Answer:
135.09 kg
Step-by-step explanation:
First, we must determine the total weight of each bicycle including their boxes. To do this, we must add 3.41 kg and 11.6 kg. 3.41 + 11.6 = 15.01.
Next, multiply the weight of one bike and its box to the total amount of bicycles there are. There are 9 bikes, so 15.01*9 = 135.09 kg.
To find the total mass of all bicycles and their boxes, add the mass of one bicycle (11.6 kg) and its box (3.41 kg) to get the total mass for one unit (15.01 kg), and then multiply by the total number of bicycles (9), resulting in a total mass of 135.09 kg.
The total mass of all the bicycles and their packing boxes can be calculated by first determining the mass of one bicycle with its box, and then multiplying that by the total number of bicycles being shipped. The mass of one bicycle is 11.6 kg and the mass of its packing box is 3.41 kg. Adding these together gives us the total mass for one bicycle and its box.
Mass of one bicycle: 11.6 kg
Mass of one box: 3.41 kg
Total mass for one bicycle and its box: 11.6 kg + 3.41 kg = 15.01 kg
This total mass for one bicycle and its box must then be multiplied by the number of bicycles to obtain the total mass for all bicycles and their boxes.
Number of bicycles: 9
Total mass for all bicycles and boxes: 9 * 15.01 kg = 135.09 kg
Therefore, the total mass of all the bicycles and their packing boxes is 135.09 kg.
Classify the following triangle as acute, obtuse, or right
A. Acute
B Right
C Obtuse
D None of these
The correct answer is option C as the shown triangle is obtuse.
Based on the image, the triangle has the following angles:
132°36°12°Step 1: Sum of angles in a triangle
The sum of the angles in any triangle is always 180 degrees.
Therefore:
[tex]132^0 + 36^0 + 12^0 = 180^0[/tex]
Step 2: Analyze angle measures
Looking at the triangle, the following are the angle measures:
One angle [tex](132^0)[/tex] is greater than [tex]90^0[/tex].
There are no angles exactly equal to [tex]90^0[/tex].
All other angles [tex](36^0,12^0)[/tex] are less than [tex]90^0[/tex].
Step 3: Triangle classification
Based on the angle measures, the following is evident.
The triangle has one angle greater than [tex]90^0[/tex], so it cannot be acute (where all angles should be less than [tex]90^0[/tex]).
The triangle does not have any angles equal to [tex]90^0[/tex], so it is not right.
Since it has one angle greater than [tex]90^0[/tex], the triangle is classified as obtuse.
Thus the triangle is obtuse and it corresponds to option C.

A 6 inch personal pizza has 600 calories with 240 from fat. A 14 inch pizza is cut into slices. Estimate the number of calories in one slice
Answer:
175 calories.
Step-by-step explanation:
There are 600 calories with 240 from fat in a 6 inch personal pizza.
If we consider the number of calories in each inch of pizza to be constant.
Then, a 14 inch pizza will have [tex]\frac{600}{6} \times 14 = 1400[/tex] calories.
Now, a standard 14 inch pizza has 8 slices and if the 14 inch pizza is cut into 8 slices then in each slice there will be [tex]\frac{1400}{8} = 175[/tex] calories. (Answer)
The estimated number of calories in one slice of a 14-inch pizza, assuming it is cut into 8 slices, is 408 calories.
Explanation:In this problem, we need to work with the concept of Ratios and Proportions in order to estimate the amount of calories in one slice of a 14-inch pizza. Firstly, we may want to calculate how many 6-inch pizzas fit into a 14-inch pizza. To do this we can use the formula for the area of a circle (πr²) where the r represents the radius.
For the 6-inch pizza, the radius is 3 inches, and for the 14-inch pizza, the radius is 7 inches. Therefore, according to the formula, we have:
Area of 6-inch pizza: π * 3² = 9π
Area of 14-inch pizza: π * 7² = 49π
By dividing the area of the 14-inch pizza by the area of the 6-inch pizza, we find that around 5.44 of 6-inch pizzas fit into the 14-inch pizza:
49π/9π = 5.44
So, the 14-inch pizza has roughly 5.44 times more calories than the 6-inch pizza, meaning it would have 600 calories * 5.44 = 3264 calories.
If you split the pizza into 8 slices, each slice of pizza would therefore have 3264 calories / 8 slices = 408 calories.

A flower shop sells tulips and roses. The price of each tulip is the same, and the price of each rose is the same. One customer bought 7 tulips and 9 roses for $25.90. Another customer bought 4 tulips and 8 roses for $19.80. How much will it cost a customer to buy 5 tulips and 6 roses?
It will cost a customer $17.75 to buy 5 tulips and 6 roses.
Step-by-step explanation:
Let,
Cost of one tulip = x
Cost of one rose = y
According to given statement;
7x+9y=25.90 Eqn 1
4x+8y=19.80 Eqn 2
Multiplying Eqn 1 by 4
[tex]4(7x+9y=25.90)\\28x+36y=103.60\ \ \ Eqn\ 3[/tex]
Multiplying Eqn 2 by 7
[tex]7(4x+8y=19.80)\\28x+56y=138.60\ \ \ Eqn\ 4\\[/tex]
Subtracting Eqn 3 from Eqn 4
[tex](28x+56y)-(28x+36y)=138.60-103.60\\28x+56y-28x-36y=35\\20y=35[/tex]
Dividing both sides by 20
[tex]\frac{20y}{20}=\frac{35}{20}\\y=1.75[/tex]
Putting y=1.75 in Eqn 1
[tex]7x+9(1.75)=25.90\\7x+15.75=25.90\\7x=25.90-15.75\\7x=10.15[/tex]
Dividing both sides by 7
[tex]\frac{7x}{7}=\frac{10.15}{7}\\x=1.45[/tex]
Cost of 5 tulips and 6 roses = 5x+6y = 5(1.45)+6(1.75) = 7.25+10.50 = $17.75
It will cost a customer $17.75 to buy 5 tulips and 6 roses.

The cost to customer to buy 5 tulips and 6 roses will be $17.75
Given that:The price of all tulips are same.The price of all roses are same.Price of 7 tulips and 9 roses is $25.90 Price of 4 tulips and 8 roses is $19.80To find:Cost of buying 5 tulips and 6 roses.
Naming the prices:Let price of one tulip be $xLet price of one rose be $yForming system of equations:By given data, we have:
7 tulip + 9 roses costs $25.90
or
[tex]7x + 9y = 25.9[/tex]
And
4 tulips + 8 roses costs $19.8
or
[tex]4x + 8y = 19.8[/tex]
Thus, we have two equations.
Using method of substitution:From equation first, we have:
[tex]7x + 9y = 25.9\\\\ x = \dfrac{25.9-9y}{7} [/tex]
Substituting this value in second equation, we get:
[tex]4(\dfrac{25.9 - 9y}{7}) + 8y = 19.8\\\\ 103.6 - 36y + 56y = 138.6\\ 20y = 138.6 - 103.6\\\\ y = \dfrac{35}{20} = 1.75\\ [/tex]
Thus, we have:
[tex]x = \dfrac{25.9-9y}{7} \\ \\ x = \dfrac{25.9 - 15.75}{7} = 1.45[/tex]
Thus, the price of a tulip = x = $1.45
and the price of a rose = y = $1.75
Now, calculating price of 5 tulips and 6 roses:
[tex]\: \rm Total \: Cost = 5x + 6y = 5 \times 1.45 + 6 \times 1.75 = \$17.75[/tex]

Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.
Answer:
c ≥ 56 is the REQUIRED INEQUALITY.
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the inequality and solution to represent the number of cans, c, that Xander must still collect.
Now, here:
The number of cans Xander needed to collect = At least 120
The number of items already collected = 64
c: the number of cans, c, that Xander must still collect.
Now, the number of cans to be collected - Cans already collected
= 120 - 64 = 56
So, the number of can he must collect to make a TOTAL OF AT LEAST 120 cans = 56 cans
⇒ The number of cans to be collected ≥ 56 cans
⇒c ≥ 56 cans
or, c ≥ 56 is the REQUIRED INEQUALITY.
Answer:
c ≥ 56 is the REQUIRED INEQUALITY.

Kittens weigh about 100 grams when born and gain 7 to 15 grams per day. If a kitten weighed 100 grams at birth and gained 8 grams per day, in how many days will the kitten triple its weight?
It would take the kitten 25 days after its birth to triple its weight.
Solution:
kitten weighed 100 grams at birth
And gained 8 grams per day
kitten needed to triple its weigh
Which means, they have to become 3 x 100 = 300 grams
Let "x" be the number of days needed to be 300 grams
Then we can say,
300 grams = 100 grams at birth + 8 grams( number of days)
[tex]300 = 100 + 8x\\\\8x = 300-100\\\\8x = 200\\\\Divide\ both\ sides\ by\ 8\\\\x = 25[/tex]
Thus it would take the kitten 25 days after its birth to triple its weight.
Ms. Willis drives to a conference in 5 hours.Due to bad weather on the return in trip home, she drives the same route in 8 hours at an average speed that is 24 miles per hour slower than her trip to the conference
Answer:
Distance = 192 km
Step-by-step explanation:
To calculate the distance, the distance is given by the formula:
s = vt
where s = distance
v = average speed
t = time taken to travel
therefore, the distance is given as
s = 24miles/hour× 8 hours
= 192 miles.
The total distance is 192 miles.
To calculate the average speed on the first trip to the conference, divide the distance by the time like this:
s = vt
v = s/t
= 192 miles/ 5 hours
= 38.4 miles per hour
As you can see, the driver drove faster than she did when she was driving in bad weather.
The carnival fundraiser at Central High School raised $400 on Thursday. On Friday, 280% of that amount was raised. How much money did the carnival raise on Friday? Which statements are correct? Check all that apply. The answer will be less than $400 because 100 is less than 280. The answer will be greater than $400 because 280 is greater than 100. (100)(4) = 400, so (280)(4) = the amount of money the carnival raised on Friday. 400 + 280 = the amount of money the carnival raised on Friday. The carnival raised $680 on Friday. The carnival raised $1,120 on Friday.
Multiply the amount raised by 280%
Rewrite 280% as a decimal by moving the decimal point 2 places to the left
280%. = 2.80
400 x 2.80 = $1120.00
Answers are:
The answer will be greater than $400 because 280 is greater than 100.
(100)(4) = 400, so (280)(4) = the amount of money the carnival raised on Friday.
The carnival raised $1,120 on Friday.

-5(x-3=14
Answer:
x = 1/5
Step-by-step explanation:
To solve, simplify the equation, then isolate "x". Start with the distributive property, where you multiply the number outside the brackets with each number inside the bracket. Isolate "x" by bringing all the other numbers to the right side on the equal sign. When moving a number, do its reverse operation to the whole equation.
-5(x-3) = 14 Distribute. Multiply -5 by "x", subtract -5 times 3.
(-5)x - (-5)3 = 14 Multiply -5 and 3
(-5)x - (-15) = 14 Two negatives make a positive
(-5)x + 15 = 14 Remove brackets around -5
-5x + 15 = 14 Start isolating
-5x + 15 - 15 = 14 - 15 Subtract 15 from both sides
-5x = -1 Left side: 15 cancelled out. Right side: 14-15 = -1
-5x/-5 = -1/-5 Divide both sides by -5.
x = 1/5 Solved for "x"
Check your answer by substituting "x" with the answer you found:
-5(x - 3) = 14
-5(([tex]\frac{1}{5}[/tex]) - 3) = 14 Change "x" to 1/5.
-5(([tex]\frac{1}{5}[/tex]) - [tex](\frac{5}{5})(\frac{3}{1})[/tex]) = 14 Make 5 the common denominator
-5([tex]\frac{1}{5}[/tex] - [tex]\frac{15}{5}[/tex]) = 14 Multiply the fractions across
-5([tex]\frac{1-15}{5}[/tex]) = 14 Combined the fractions on top of the same denominator
-5([tex]-\frac{14}{5}[/tex]) = 14 Simplify numerator
[tex]\frac{-5*-14}{5}[/tex] = 14 Multiply by combining into the numerator
[tex]\frac{70}{5}[/tex] = 14 Divide the top by the bottom of the fraction
14 = 14 Same answer on both sides
LS = RS Left side equals right side
Therefore the answer is correct.
