Bradley $15 painting a fence for two hours and 30 dollars for pressure washing the patio and deck for 4 hours. Did he learn the same amount per hour for. Both jobs? Explain
Answers
Yes, he earns the same amount per hour for the fence because in two hours he earned 15. The pressure washing and deck was 4 hours and every 2 hours he got 15.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that, Bradley $15 for painting a fence for two hours and 30 dollars for pressure washing the patio and deck for 4 hours.
Bradley $15 painting a fence for two hours, its unit rate is
=$15 / 2 hours
=$ 7.5 per hour
If 30 dollars for pressure washing the patio and deck for 4 hours, the unit rate is
=$ 30 /4 hours
=$ 7.5 / hour
Thus, he earns the same amount per hour for the fence because in two hours he earned 15. The pressure washing and deck was 4 hours and every 2 hours he got 15.

Keisha bought these supplies for school:
4 packs of pencils that cost $0.85 each
6 packs of pens for $1.25 each
5. What was the total cost of the pencils and pens, including a 6% tax?
A
$13.35
B
$10.90
C
$11.55
D
$2.23
.
Answers
Answer:
C. $11.55
Step-by-step explanation:
First, multiply 4 by $0.85 to get an answer of $3.40. Next, multiply 6 by $1.25 to get an answer of $7.50. Add up the cost of the pencils and pens by adding $3.40 and $7.50 to get $10.90. Next, we have to add the tax. Multiply $10.90 by 0.06 to get $.65. Add the $.65 to the $10.90 for a grand total of $11.55. Hope this helps!

Answers
9514 1404 393
Answer:
(c) y = 3|x| + 5
Step-by-step explanation:
The vertex is at (0, 5), so the basic function has been translated up 5 units.
The slope of each line has a magnitude of 3, so the basic function has been scaled vertically by a factor of 3.
The transformation ...
g(x) = c·f(x) +h
is a vertical scaling by a factor of c, and a translation upward by h units. Here, we have c=3 and h=5. The basic function is f(x) = |x|, so the transformed function shown on the graph is ...
y = 3|x| +5

The trick is to let the letters = points of a clock that keeps time this way.
l = 9 oclock
C = 3 oclock
-H= -8
Formula
(x - l) / C = -H
Solution
Substitute the givens into the equation
(x - 9) / 3 = -8 Multiply both sides of the equation by 3
3*(x - 9)/3 = -8*3 Simplify
(x - 9) = - 24 Remove the brackets
x - 9 = - 24 Add 9 to both sides.
x-9+9 = -24+9 Combine

Amy uses 48-cent stamps and 7-cent stamps to mail a gift card to a friend. If the postage is $2.07, how many of each stamp did Amy use?
Answers
9514 1404 393
Answer:
3 48-cent stamps
9 7-cent stamps
Step-by-step explanation:
The number of 48-cent stamps Amy can use is less than 207/48 ≈ 4.3, so we can find the numbers by trial and error. We want ...
48a +7b = 207 . . . . . . postage in cents, where a, b are the numbers of stamps
b = (207 -48a)/7 = 29 4/7 -a(7 -1/7) = (29 -7a) +(a+4)/7
In order for b to be an integer, we must have (a+4) a multiple of 7. The least value of 'a' that will make this true is a=3. That value gives ...
b = (29 -7·3) +(3+4)/7 = 8 +1 = 9
Amy used 3 48-cent stamps and 9 7-cent stamps.

Express the edge length of a cube as a function of the cube's diagonal length d. Then express the surface area and volume of the cube as a function of the diagonal length.
a. A function for the edge length of a cube is L(d) = _________________
b. A function for the surface area of a cube is Ald) = _____________
c. A function for the volume of a cube is V(d) = ________________
Answers
Answer:
Step-by-step explanation:
If L is the length of a side, the longest diagonal in the cube is
d = √(L² + L² + L²) = √(3L²) = L√3
meaning
a) L(d) = d/√3 = ⅓d√3
b) A(d) = 6(L(d))² = 6(⅓d√3)² = 6(⅟₉d²(3)) = 2d²
c) V(d) = (L(d))³ = (⅓d√3)³ = ⅟₂₇d³3√3 = ⅟₉d³√3
If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-fifths full?
Answers
Answer:
3/5 of 30 = (3/5)*30
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.
