Answer:
Length = 45
Width = 38
Step-by-step explanation:
2a + 2(a + 7) = 166
4a + 14 = 166
4a = 152
a = 38
a = Width
38 = Width
a + 7 = Length
(38 + 7) = Length
45 = Length
34. If each interior angle has a measure of 175.2°, how many sides does the polygon have?
Answer:
75 sides when the interior angle is 175.2
Step-by-step explanation:
these problems are all done the same way. Subtract the interior angle from 180 and divide the result into 360
360/(180 - 175.2)
360 / 4.8
75 sides
Use the remainder to divide 5x^2+9x-2 by x+3. What is the remainder?
Answer:
16
Step-by-step explanation:
Using the Remainder theorem
f(x) divided by (x + h) then the remainder is the value of f(- h)
here the divisor is (x + 3), thus remainder is f(- 3)
remainder = 5(- 3)² + 9(- 3) - 2 = 5(9) - 27 - 2 = 45 - 29 = 16
Dave works for 5 hours double time and he earns $98 find his normal hourly year rate
Answer: $9.8 per hour
Step-by-step explanation:
If Dave works for 5 hours at double time, then he gets paid for 10 hours of work. If he earned $98 for 10 hours of work, all you need to do is divide the amount of money earned by the hours of work. [tex]\frac{98}{10}[/tex]=9.8 dollars per hour.
what is the measurement of
Answer: Angle A = 120° and angle C = 45°
Step-by-step explanation: The first thing to note at the back of our minds is that the sum of the interior angles of a triangle equals 180°. Given that the three angle are available, we can start by adding them all together. Hence,
{12x + 12} + 15 + {3x + 18} = 180
12x + 12 + 15 + 3x + 18 = 180
By collecting like terms, we arrive at,
12x + 3x + 12 + 15 + 18 = 180
15x + 45 = 180
Subtract 45 from both sides of the equation
15x = 135
Divide both sides of the equation by 15
x = 9
At this point, we can now substitute for the value of x = 9 in the expressions representing angles A and C.
Angle A = 12x + 12
= 12(9) + 12
= 108 + 12
= 120
Angle A = 120°
Angle C = 3x + 18
= 3(9) + 18
= 27 + 18
= 45
Angle C = 45°
Mrs. Rivera ate 3/8 of a
pizza and Ms. Carter ate 4/8
of a pizza. How much pizza
did they eat altogether?
Answer:
They ate 7/8 of a pizza altogether.
Step-by-step explanation:
So, you know Mrs. Rivera ate 3/8 of a pizza and Ms. Carter ate 4/8 of a pizza.
You add 3/8 + 4/8 and you get 7/8.
The ate 7/8 of a pizza altogether.
The quantity of pizza that Mrs. Rivera and Ms. Carter ate altogether is equal to [tex]\frac{7}{8}[/tex]
Given the following data:
Fraction Rivera ate = [tex]\frac{3}{8}[/tex]Fraction Carter ate = [tex]\frac{4}{8}[/tex]To calculate how much (quantity) pizza they ate altogether:
A fraction can be defined as a numerical quantity that isn't a whole number.
Hence, a fraction is simply a part of a whole number.
In this exercise, we would add up the two fractions, so as to calculate how much (quantity) pizza they ate altogether.
[tex]Total \;quantity = \frac{3}{8} + \frac{4}{8}[/tex]
Lowest common multiple (LCM) = 8
[tex]Total\;quantity = \frac{4\;+\;3}{8} \\\\Total\;quantity = \frac{7}{8}[/tex]

which point is an x intercept of the quadratic function f(x) =(x-8)(x+9)
Answer:
(- 9, 0) and (8, 0)
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 8)(x + 9) = 0
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x - 8 = 0 ⇒ x = 8
The x- intercepts are x = - 9 and x = 8

An object is launched from a platform.
Its height (in meters), x seconds after the launch, is modeled by:
h(x)=-5x2verb +20x+60
What is the height of the object at the time of launch?

60 feet
Step-by-step explanation:
The height, h (in meters), of the object launched from a platform is represented by the equation
[tex]h=h(x)=-5x^2+20x+60[/tex]
where x is the time (in seconds) passed after the launch.
The time of launch is [tex]x=0[/tex] (0 seconds passed after the launch)

a jar of peanut butter contains 452 with a standard deviation of 10.4 g assuming a normal distribution find the probability that a jar contains less than 449 grams
Answer:
0.3859
Step-by-step explanation:
Assuming on the average, a jar of peanut butter contains 452 grams, with a standard deviation of 10.4 grams.
Then we have
[tex] \mu = 452 \: and \: \sigma = 10.4[/tex]
We want to find the probability that a jar contains less than 449 grams.
We first determine the z-score of x=449 grams using:
[tex]z = \frac{x - \mu}{ \sigma} [/tex]
We plug in these values to get:
[tex]z = \frac{449 - 452}{10.4} [/tex]
[tex]z = \frac{ - 3}{10.4} = - 0.29[/tex]
Now we read from the standard normal distribution table the area that corresponds to a z-score of -0.29
P(X<449)=0.3859
To find the probability that a jar contains less than 449 grams, calculate the z-score and use a standard normal distribution table or calculator.
Explanation:To find the probability that a jar contains less than 449 grams, we can use the standard normal distribution and the z-score formula. The z-score is calculated as (X - mean) / standard deviation. In this case, X = 449, mean = 452, and standard deviation = 10.4. By substituting these values into the formula, we can find the z-score, and then use a standard normal distribution table or calculator to find the probability.
1. Calculate the z-score: (449 - 452) / 10.4 = -0.2885
2. Use a standard normal distribution table or calculator to find the probability associated with a z-score of -0.2885. The probability is approximately 0.3830, or 38.30%.
