B-11 4/15
C- 4 1/2
D-10 9/15
9514 1404 393
Answer:
B -11 4/15
Step-by-step explanation:
-7 3/5 -3 2/3 = -(7 3/5 +3 2/3)
= -((7 +3) +(3/5 +2/3)) = -(10 +9/15 +10/15)*
= -(10 +19/15) = -(10 +1 4/15)
= -11 4/15

sin 70 in surf form
Step-by-step explanation:
Calculate sin(70)°
Determine quadrant:
Since our angle is between 0 and 90 degrees, it is located in Quadrant I In the first quadrant, the values for sin, cos and tan are positive.
Determine angle type:
70 is an acute angle since it is less than 90°
sin(70) = 0.93969262030844
Write sin(70) in terms of cos
Since 70° is less than 90,
we can express this in terms of a cofunction
sin(θ) = cos(90 - θ)
sin(70) = cos(90 - 70)
sin(70) = cos(20)

Joaquin is four more than half Marjorie’s age. Marjorie is also 32 less than three times Joaquin’s age.
How old is Marjorie?
Answer:
She is 40 years of age
Step-by-step explanation:
Let Joaquin age be j
Let Marjorie age be m
From the first part of the question;
j = 4 + m/2
Secondly;
m =3j - 32
Multiply equation i through by 2
2j = 8 + m
m = 2j-8
Equate both m
2j-8 = 3j-32
3j-2j = 32 -8
j = 24
m = 2j-8
m = 2(24)-8
m = 48-8
m = 40

please solve this equation and show work 4y−70=12y+2
Answer:
Step-by-step explanation:
Simplifying 4y + -70 = 12y + 2
Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y
Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70
Divide each side by -8.
So y = -9 is your answer.

Answer:
(3, - 2)
given y = - 2, then
- 2x + 4 = - 2 ( solve for x )
subtract 4 from both sides
- 2x = - 6 ( divide both sides by - 2 )
x = -6/-2 = 3

Leah would like to earn at least $120 per month. She babysits for $5 an hour and works at an ice cream shop for $10 per hour. Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop.
This question is incomplete
Complete Question
Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $10 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y
represent the number of hours Leah works at the ice cream shop.
Answer:
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120
Step-by-step explanation:
Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop. Leah cannot work more than a total of 20 hours per month.
Hence:
x + y ≤ 20 ...... Equation 1
Leah would like to earn at least $120 per month.
She babysits for $5 an hour and works at an ice cream shop for $10 per hour.
Hence, out Equation is given as:
x × $5 + y × $10 = $120
5x + 10y ≥ 120..... Equation 2
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
To find x and y:
x + y = 20
x = 20 - y
5x + 10y = 120
Substitute: 20 - y for x
5(20 - y) + 10y = 120
100 - 5y + 10y = 120
Collect like terms
- 5y + 10y = 120 - 100
5y = 20
y = 20/5
y = 4 hours
Note:
x = 20 - y
x = 20 - 4
x = 16 hours
Hence:
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120

Mr. Stip bought a new pair of Jordans and 4 new polo shirts. The price of one pair of jordans were double the amount of one polo shirt. If Mr. Stip spent $510, determine the price he paid for the Jordans.
9514 1404 393
Answer:
$170
Step-by-step explanation:
If the price of a pair of Jordans is the same as the price of two shirts, the total purchase has a value equivalent to that of 3 Jordans.
pair of Jordans = $510/3 = $170

Answer:
B
Step-by-step explanation:
Volume = 4/3 pi r^3
r = 15 / 2
r = 7.5
Volume = 4/3 * 3.14 * 7.5^3
Volume = 4.1867 * 421.875
Volume = 1766.3 Cubic inches.

Hans has done a mistake in the second step.
The correct answer is:
