B, because you would subtract the total from what she ate it will equal what she has left and since c represents the total then you would have the equation c-8=14.
Step-by-step explanation:
Penny drives a truck. The function p = 20h + 75 represents her daily pay, in dollars, for working h hours. She travels 60 miles each hour. She also receives $0.10 for each bonus mile she drives. The function b = 60h × (0.10) represents the amount she earns for her bonus. Which function represents Penny's earnings, P, for driving h hours?
Answer:
Penny's earning for driving h hours is represented by the function
P = 26h + 75
Step-by-step explanation:
- The function p = 20h + 75 represents her daily pay
- The function b = 60h × (0.10) represents the amount she earns for her bonus.
Penny's earnings is the addition of her daily pay and bonus.
It is represented by the function P.
P = (20h + 75) + 60h × 0.10
Simplifying this, we have
P = 20h + 75 + 6h
= 26h + 75

Given:
Quadrilateral PQRS is a rhombus.
To find:
The value of y.
Solution:
In the rhombus PQRS,
PS = 10y and SR = y + 45
Property of rhombus:
All sides are congruent.
⇒ PS = SR
⇒ 10y = y + 45
Subtract y from both sides.
⇒ 10y - y = y + 45 - y
⇒ 9y = 45
Divide by 9 on both sides.
[tex]$\Rightarrow \frac{9y}{9} =\frac{45}{9}[/tex]
⇒ y = 5
The value of y is 5.
The two isosceles triangles are similar.
Answer:79
Step-by-step explanation:
Since a triangle has a total of 180 degrees in the interior, you can subtract 22 from 180 to get 158.Because the triangle is isosceles, the 2 remaining angles have the same measure. All you need to do now is to divide 158 by 2.
You get 59.
Morgan babysits every Saturday. The equation d = 9.5h
represents how much she earns after h hours. Last week,
she also babysat on Friday and earned $63 for 6 hours.
Which statement is true?
A. Morgan earns the same amount per hour on Friday and Saturday.
B. Morgan’s hourly rate on Friday $12 per hour.
C. Morgan earns more money per hour on Friday.
D. Morgan earns more money per hour on Saturday.
Answer:
Morgan earns more money per hour on Friday.
Step-by-step explanation:
Using the equation d= 9.5h, we see that the hourly rate for Saturday is 9.5, which is $9.50.
On Friday, she babysits 6 hours and earns $63. This is an hourly rate of 63/6 = 10.5, or $10.50.
She earns more money on Friday.
The statement that is true is C. Morgan earns more money per hour on Friday.
From the information given, Morgan babysits every Saturday and the equation is given as d = 9.5hLast week, she also babysat on Friday and earned $63 for 6 hours. This means the rate will be 63/6 = $10.5Therefore, based on this, we can see that the rate on Friday is better.Therefore, Morgan earns more money per hour on Friday.

Find the value of x. The diagram is not to scale. Explain your reasoning.
Answer:
x = 24
Step-by-step explanation:
Since SR = ST then Δ RST is isosceles, thus the base angles are congruent.
∠ SRT = ∠ STR = 4x - 60
∠ STR and ∠ STU are adjacent and supplementary, thus
∠ STR + ∠ STU = 180, substitute values
4x - 60 + 6x = 180, that is
10x - 60 = 180 ( add 60 to both sides )
10x = 240 ( divide both sides by 10 )
x = 24
Find the area of the rhombus.
A=
square units
Answer: A=70 square units
Step-by-step explanation:
The area of a triangle can be found using the formula [tex]A=\frac{1}{2} bh[/tex]
Let 5=h and 7=b
Plug in the values and solve
[tex]A=\frac{1}{2} (7)(5)[/tex]
[tex]A=17.5[/tex]
However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.
[tex]A=17.5*4[/tex]
[tex]A=70[/tex]
n the Present Value of an Ordinary Annuity formula, what does the n represent?
a.
nominal interest rate
c.
number of periods
b.
number of payments
d.
decimal number of percentage
update: got the answer... it is c.
Answer:
C, number of periods
Step-by-step explanation:
ed2022
Final answer:
The 'n' in the annuity formula stands for Option C. the total number of payments or periods, essential for calculating the present value of equally spaced payments over time.
Explanation:
The letter 'n' in the Present Value of an Ordinary Annuity formula represents the total number of payments or periods over which the payments are made. When calculating the present value of an annuity, the formula accounts for each payment being discounted by the interest rate per period. Therefore, the present value of an annuity is calculated by summing up the values of all the payments, each discounted back to their present value.
An example of using the formula could relate to calculating the present value of a series of fixed mortgage payments over time. If the monthly interest rate is 'r', and there are 'n' total payments (for instance, 360 payments for a 30-year mortgage), the present value would account for each payment by discounting it over the number of periods to reflect the time value of money.

Final answer:
To convert 56/15 to a decimal and round to the nearest tenth, you divide 56 by 15 to get 3.7333 and then round it down to 3.7 since the hundredths place is less than 5.
Explanation:
The question is asking to convert the fraction 56/15 to a decimal and round it to the nearest tenth. To convert a fraction to a decimal, you need to divide the numerator by the denominator. In this case, divide 56 by 15. The decimal form of 56/15 is approximately 3.7333. When rounding this number to the nearest tenth, we look at the hundredths place, which is a 3. Since it's less than 5, we do not round up. Therefore, the decimal rounded to the nearest tenth is 3.7.

The formula for the circumference C of a circle with diameter d is C = xd. Write an expression to represent the circumference of the following circle
The circumference of a circle is calculated based on its diameter using the formula C = πd. Replace 'd' with the value of the circle's diameter to obtain an expression representing the circumference.
Explanation:The formula for the circumference C of a circle with a diameter d is given by C = πd, where π (Pi) is approximately 3.14. To write an expression to represent the circumference of a specific circle, simply replace the term 'd' with the actual diameter of the circle. For example, if the diameter of the circle is 10 units, then the expression for the circumference would be C = π * 10 or C = 3.14 * 10, hence the circumference C of the circle would be about 31.4 units.
