reduce the fraction 34/48 to its lowest term
Answer: 17/24
Step-by-step explanation: To write the fraction 34/48 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 34 and 48.
Since the factors of 34 are 1, 2, 17, 34 and the factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48, the greatest common factor of 34 and 48 is 2.
So we divide the numerator and the denominator of 34/48 by 2.
34 divided by 2 is 17 and 48 divided by 2 is 24.
So 34/48 written in lowest terms is 17/24.

Luis is asked to construct a triangle with a 35° angle and a 45 angle How many different triangles could he draw with
these angle measures?
There is only one unique triangle that can be drawn with a 35° angle and a 45° angle, as the third angle is determined to be 100° to make the sum 180°.
To determine how many different triangles can be constructed with a 35° angle and a 45° angle, we can use the fact that the sum of angles in a triangle is always 180°. Adding the given angles, we get 35° + 45° = 80°. Subtracting this from 180° gives us the third angle, which is 180° - 80° = 100°. Since the sum of the angles is 180° and all angles are determined, there is only one unique triangle that can be drawn with these angle measures
The icecream parlor has 30 flavors, but for the last week they have only had 25 flavors. Find the percent of change. Tell if it is an increase or decrease.
Answer:
The percent of change is 20%.
And it is increased by last month.
Step-by-step explanation:
Given:
The ice cream parlor has 30 flavors, but for the last week they have only had 25 flavors.
Now, to find the percent of change.
Flavors ice cream parlor has = 30.
Flavors last week they had = 25.
So, the flavors increased from last week by:
[tex]30-25=5\ flavors.[/tex]
Now, to get the percent of change:
[tex]\frac{5}{25} \times 100[/tex]
[tex]=\frac{500}{25}[/tex]
[tex]=20\%.[/tex]
Thus, the percent of change is 20%.
The flavor is increased by last month.
Therefore, the percent of change is 20%.
And it is increased by last month.
Final answer:
The percent of change is a decrease of 16.67%, calculated by subtracting the new amount of flavors from the original, dividing by the original amount, and multiplying by 100.
Explanation:
To find the percent of change in the number of flavors at the ice cream parlor, we will subtract the original amount of flavors from the new amount, divide that by the original amount, and then multiply by 100. The original amount of flavors was 30, and the new amount is 25. Here is the calculation:
Subtract the new amount from the original amount: 30 - 25 = 5
Divide the change by the original amount: 5 ÷ 30 = 0.1667
Multiply by 100 to get the percent: 0.1667 x 100 = 16.67%
The percent of change is a decrease of 16.67% since the number of flavors went down from 30 to 25.

Sofia places 26 tiles representing each letter of the alphabet into a bag. Five of the tiles represent the vowels A, E, I, O, and U. Sofia will randomly select 1 tile from the bag and without replacement select another tile from the bag. Sofia will draw two tiles from the bag 260 times. What is a reasonable prediction for the number of times Sofia will select a consonant tile and a vowel tile?
Answer:
42 times.
Step-by-step explanation:
The number of total alphabet = 26 tiles
The number of vowels = 5
The number of consonant = 26 - 5 = 21
Sofia will randomly select 1 tile from the bag and without replacement select another tile from the bag.
The probability to select consonant at first time = 21/26
Total tiles after the first selection = 26 - 1 = 25
The probability to select vowels at second time = 5/25
The probability to select consonant and vowels = [tex]\frac{21}{26} *\frac{5}{25} =\frac{21}{130}[/tex]
Sofia will draw two tiles from the bag 260 times.
The prediction for the number of times Sofia will select a consonant tile and a vowel tile = [tex]\frac{21}{130} *260=42 \ times[/tex]
A car approaches a stop sign going 5 m/s before it comes to a stop. If it does this in 4 seconds, what was
its acceleration?
Answer:
Acceleration = -1.25 m/s²
Step-by-step explanation:
Given data:
initial velocity = 5 m/s
Final velocity = 0 m/s since the car stopped
change in time = 4 seconds
Acceleration = change in velocity/change in time
Acceleration = (Final velocity - Initial velocity)/time
Acceleration = (0-5)/4
Acceleration = -5/4
Acceleration = -1.25 m/s²
The acceleration in negative since the car was reducing speed to stop, it can also called deceleration.
It travels 10 m and then stops.
KinematicsIt refers to the study of motion.
Given
Initial speed (u) = 5m/s
Time (t) = 4 sec
How to find distance?We know the equation of motion
[tex]\rm v = u + at\\v^{2}- u^{2} = 2as[/tex]
As final velocity (v) = 0
Then
[tex]v = u +at \\\\0 = 5 + 4a\\\\a= \dfrac{5}{4}[/tex]
then
[tex]\begin{aligned} \rm v^{2}- u^{2} &= 2as \\0^{2} - 5^{2} &= 2*\dfrac{5}{4} *s\\25 &= \dfrac{5}{2}*s \\s &= 10 m\\\end{aligned}[/tex]
Thus, it travels 10 m and then stops.

Toby wants to find the volume of a solid toy soldier.He fills a rectangular container 8 cm long, 6 cm wide,and 10 cm high with water to a depth of 4 cm. Toby totally submerges the toy soldier in the water. The height of the water with the submerged toy soldier is 6.6 cm. Which of the following is closest to the volume, in cubic centimeters, of the toy soldier?
A. 125 B. 156 C. 192 D. 208 E.317
The volume of the toy is 125 cubic cm ,option A is the closest answer.
Step-by-step explanation:
Given:
A rectangular container .
Length of the container =8 cm
Width of the container = 6 cm
Height of the container when water is filled = [tex](h_1)[/tex] = 4 cm
Height of the container when the toy is submerged = [tex](h_2)[/tex] =6.6 cm
Volume of the toy = Volume of the container with the toy - Volume of the container (with water)
Volume of the toy = [tex](l\times b\times h_2) - (l\times b\times h_1)[/tex]
= [tex](l\times b\times)(h_2-h1)[/tex]
= [tex](6\times 8)(6.6-4)[/tex]
= [tex]48\times 2.6[/tex]
= [tex]124.8[/tex] cubic centimeters.
So,the closest value to the volume of the toy is 125 cubic centimeters.
The closest volume, in cubic centimeters, of the toy soldier is 124.8 cm³.
To find the volume of the toy soldier submerged in water, we can use the following steps:
1. Calculate the initial volume of water in the container: 8 cm x 6 cm x 4 cm = 192 cubic cm.
2. Determine the final volume of water with the toy soldier submerged: 8 cm x 6 cm x 6.6 cm = 316.8 cubic cm.
3. Subtract the initial volume of water from the final volume with the toy soldier submerged: 316.8 cubic cm - 192 cubic cm = 124.8 cubic cm.
Therefore, the closest volume, in cubic centimeters, of the toy soldier is 124.8 cm³.

Complete the sentence to finish the explanation of how you could show that points A, B, and C on the coordinate plane are collinear.
Answer:
First blank: the equation of the line that passes through A and BSecond blank: is a solution of the equation
Explanation:
Three or more points are collinear if and only if they are on the same line, and, thus they are solutions, of the same equation of the line.
When you know two points through their coordinates you can always find the equation of the line:
Point A (x₁, y₁)Point B (x₂, y₂)You can find the slope, m, of that line by using the slope formula:
m = rise / run = Δy / Δx = (y₂ - y₁) / (x₂ - x₁)And then, you apply the point-slope equation:
y - y₁ = m (x₂ - x₁)Since you know m, x₁, and y₁, your equation is determined.
Once you have your equation, substitute the x and y coordinates with the coordinates of the point C. If, and only if, the equation is satisfied, the point C is on the same line and the three points are collinear.

Bill buys a stock that decreases by 20% on the first day, and then on the second day the stock increases by 30% of its value at the end of the first day. What was the overall percent increase in Bill's stock over the two days?
Please answer someone!
The over all percent increase in Bill's stock over the two days is 4%
Step-by-step explanation:
The given is:
Bill buys a stock that decreases by 20% on the first dayOn the second day the stock increases by 30% of its value at the end of the first dayWe need to find what was the overall percent increase in Bill's stock over the two days
Assume that Bill buys the stock by $x
∵ Bill buys the stock by $x
∵ The stock decreases by 20% on the first day
- Find the 20% of x
∵ 20% × x = [tex]\frac{20}{100}[/tex] × x = 0.2 x
∴ The cost at the end of the 1st day = x - 0.2 x = 0.8 x
∵ The stock increases by 30% of its value at the end of the 1st day
- Find the 30% of 0.8 x
∵ 30% × 0.8 x = [tex]\frac{30}{100}[/tex] × 0.8 x = 0.3 × 0.8 x = 0.24 x
∴ The cost at the end of the 2nd day = 0.8 x + 0.24 x = 1.04 x
To find the percentage of increased find the increasing amount and divide it by the original cost, then multiply the quotient by 100%
∵ The increasing amount = 1.04 x - x = 0.04 x
∵ The percentage of increase = [tex]\frac{0.04x}{x}[/tex] × 100%
∴ The percentage of increase = 0.04 × 100% = 4%
The over all percent increase in Bill's stock over the two days is 4%
