Answer:
$16.77
Step-by-step explanation:
1. Grapefruit cost 1/2 pound = 0.5 pound
2. Since the bag weighs 6.5 pounds, you can do 6.5/0.5 to find the number of grapefruits
3. 6.5/0.5 = 13
4. The total cost of the grapefruits would be $1.29 * 13 = $16.77

Find the measurement for x.
Answer:
x=120 degrees
Step-by-step explanation:
All triangle add up to 180 degrees so first you need to finnish the triangle which is 60 degrees. X and 60 degrees is on a straight line which means something + 60= 180.
(180-60=120)

pls help :) determine which function has a greater rate and explain how you know.
function 1: y = 2 • 0.2x
function 2:
x y
0 1
1 0.8
2 0.64
3 0.512
Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
What is an exponential function?It is modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value, that is, y when x = 0.b is the rate of change, as a decimal.Function 1 is given by:
[tex]y = 2(0.2)^x[/tex]
Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:
[tex]y = (0.8)^x[/tex]
Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.

How high will the firework be when it explodes? (Look at Photo)
Answer:
606 feet
Step-by-step explanation:
The fireword has a 5-second fuse, meaning that's how long it will take to explode.
Given the polynomial -16t² + 200t + 6, where t is the time in seconds
We need to subsitute 5 sec. (as stated in the question) for t in the polynomial, to find how high the fireworks will be when it explodes :
-16t² + 200t + 6 <== substitute 5 for t
-16(5)² + 200(5) + 6 <== square the exponent first
-16(25) + 1000 + 6 <== multiply
-400 + 1000 + 6 <== add
-400 + 1006 <== add
606 feet <== final answer
This means that it will be 606 feet high before it explodes.
Hope this helps!

A large white canvas, 9' x 21', has two triangles painted on it, one with a base of a 1' and height of 3',
and the other with a right triangle with a hypotenuse of 5' and a side of 3'. What is the probability of
throwing a drop of paint into one of the triangles?
The probability of throwing a drop of paint into one of the triangles is 3.96% if a large white canvas, 9' x 21', has two triangles painted on it, one with a base of a 1' and a height of 3', and the other with a right triangle with a hypotenuse of 5' and a side of 3'
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Total area of the canvas = 9' x 21' = 189 square units
This area is representing the total outcome = 189
Total favorable outcome = area of first triangle + area of the second
triangle
Area of the first triangle = (1/2)(1x3) = 3/2 square units
From the Pythagoras theorem:
Height = √(5² - 3²) = 4'
Area of the second triangle = (1/2)(3x4) = 6 square units
Total favourable outcome = 3/2 + 6 = 15/2
Now the probability:
[tex]= \frac{\frac{15}{2} }{189}[/tex]
= 15/378
= 0.0396×100
= 3.96%
Thus, the probability of throwing a drop of paint into one of the triangles is 3.96% if a large white canvas, 9' x 21', has two triangles painted on it, one with a base of a 1' and a height of 3', and the other with a right triangle with a hypotenuse of 5' and a side of 3'

Answer:
30.84 in
Step-by-step explanation:
First we find the circumference, which is d(pi), 12(3.14) which = 37.68. Then since the circle is a semicircle, we divide 37.68 by 2=18.84 in. Then we have to add 12 since the circle is cut in half, so add 12 to get 30.84.
Use the long division method to find the result when 4x3 + 11x2 + 30x + 18 is
divided by 4x + 3.

Answer:
50.24
Step-by-step explanation:
4²=16
16×3.14=50.24
Firstly, we must use the equation to solving a circle which is [tex]A = \pi r^2[/tex]. Since we already know pi (3.14) and the radius (4), we must plug the numbers into the formula. Here is how it should look like with the plug-ins: [tex]A = 3.14 * 4^2[/tex].
Next, we solve the formula. After solving, we get 50.24. The final answer to the problem is 50.24 inches squared.

La siguiente tabla presenta las frecuencias absolutas y relativas de las distintas caras de un dado cuando se simulan 300 lanzamientos en una página web: Si ahora se simulan 600 lanzamientos en la misma página web, Marcos cree que la frecuencia relativa de la cara con el número 6 será 0,36, porque se simula el doble de los lanzamientos originales. Por otro lado, Camila cree que la frecuencia relativa de la cara número 6 se acercará más al valor 0,166, tal como el resto de las frecuencias relativas de la tabla
La opinión correcta es la de Camila que argumenta que la frecuencia relativa de la cara con el #6 será un valor cercano a 0,166.
Qué es la frecuencia relativa?La frecuencia relativa es un término matemático que se utiliza en la estadística para referirse al número de veces que un evento se repite durante un experimento.
Por otra parte, es necesario aclara que la frecuencia relativa no se modifica en gran medida si se aumenta el número de veces de una prueba, debido a que la probabilidad de ocurrencia de este evento va a ser la misma.
De acuerdo a lo anterior, Camila tiene razón debido a que considera que el valor de la frecuencia relativa no se modifica en gran medida entre 300 o 600 lanzamientos de los dados.

(30 Points) 1. State the minimum monthly income and hourly wage per worker needed to cover monthly expenses for the family you used in part a (first picture). Then, explain how to calculate the hourly wage based on the monthly income and state the hourly wage. Assume that each full-time worker works four 40-hour work weeks per month, and each part-time worker works two 40-hour weeks per month.
2. ⦁ Keeping all other criteria the same, add a child to the family you used in part a to determine the monthly expenses. How does an additional child impact the family budget and hourly wage (second picture)? Which category was least affected by this change? Explain why you think there was little impact to this category.
The minimum monthly income will be $6165 and the hourly wage to cover the expenses will be $8.5625.
How to calculate the income?From the information given, the minimum monthly income will be $6165 since that's needed to cover the expense.
Also, the hourly income will be:
= 6165/(24 × 30)
= 6165/720
= 8.5625
The hourly income will be $8.5625.

What is the value of x that makes the equation true
Answer:
fraction:
x = [tex]\frac{1}{8}[/tex]
decimal:
x = 0.125
Step-by-step explanation:
64 divided by 8 = 8
[tex]\frac{64}{8}[/tex] = 8
So if youre changing this to multiplication you want to multiply by [tex]\frac{1}{8}[/tex]
[tex]\frac{64}{1}[/tex] * ( [tex]\frac{1}{8}[/tex] )= [tex]\frac{64}{8}[/tex] = [tex]\frac{8}{1}[/tex] = 8
Answer:
fraction:
x = \frac{1}{8}81
decimal:
x = 0.125
Step-by-step explanation:
64 divided by 8 = 8
\frac{64}{8}864 = 8
So if youre changing this to multiplication you want to multiply by \frac{1}{8}81
\frac{64}{1}164 * ( \frac{1}{8}81 )= \frac{64}{8}864 = \frac{8}{1}18 = 8

Landon Wallin is an auto mechanic who wishes to start his own business. He will need $4100 to purchase tools and equipment. Landon decides to finance the purchase with a 60-month fixed installment loan with an APR of 6%.
a) Determine Landon's finance charge.
b) Determine Landon's monthly payment.
Answer:
a.$1230
b.$20.50
Step-by-step explanation:
Assuming Landon only makes the minimum payments for the sixty months this is how you would find it
Multiply loan by percentage over the five years: 4100 x .3 = 1230
Then divide that amount by months paid: 1230/60= 20.5
