A package of 4 pairs of insulated gloves costs $29.16. What is the unit price of the pairs of gloves?
Answer:
7.29
Step-by-step explanation:
5. Mrs. Perkins hosts a birthday party for her son and 7 guests. She orders 2 cookies and a
cupcake for each child. The cost of the cupcake is $2.75, and the total bill is $46.00. What is the
cost of a cookie?
Answer:
A cookie is $1.50.
Step-by-step explanation:
Variable x = cost of cookies
For each child means the 7 guests plus Mrs. Perkins' son which equals 8.
Set up an equation:
(2x)8 + (2.75)8 = 46
Use distributive property:
16x + 22 = 46
Isolate variable x by subtracting both sides by 22:
16x = 24
Isolate variable x by dividing both sides by 16
x = 1.5
Check your work:
2(1.5) × 8 + (2.75)8 = 46
3 × 8 + 22 = 46
24 + 22 = 46
46 = 46
Correct!
Answer: $1.50 per cookie
Step-by-step explanation:
We know that each cupcake is worth $2.75 and the total bill of all her purchases is $46.
Therefore, lets multiply the cost of a cupcake times the amount of people eating them. (the sons and 7 guests which add up to 8)
2.75(8) = $22
Now take the total cost of 8 cupcakes and subtract it from the total.
46 - 22 = $24
24 dollars is equal to the cost times the amount of cookies purchased. Therefore, let X equal to the cost per cookie and multiply it times the amount of cookies purchased. The amount of cookies is equal to 2 cookies times 8 children.
(2*8)X = 24
16x=24
x= $1.50
Check:
8[ (1)(2.75) + 2X ] = 46
8[ 2.75 + (2) (1.50) ] = 46
22 + 24 = 46
46 = 46

A cylinder has a base area of 154 cm² and a height of 20cm. What is its total surface area, in cm?? Use, 22/7
A.1188
B.1200
C.1220
D.1224
Answer:
Hi there!
We've given with the base area and height. We know the formula for base area
Base area = πr²
154 = 22/7 × r²
154 × 7/22 = r²
49 = r²
√49 = r
7 = r
Now
TSA = 2πr(h + r)
TSA = 2 × 22/7 × 7(7 + 20)
TSA = 44(27)
TSA = 1188 cm²

Kelly works two jobs. She usually works at a retail store for eight hours during the day and is paid $15.23 per hour by the store. In the evening she works at a restaurant as a manager for 8 hours and is paid $24.50 per hour. How much does she make on average per hour for the day?
Answer:
Kelly makes about $19.87 per hour for the day.
Step-by-step explanation:
Solve for retail store:
15.23 × 8
121.84
Solve for restaurant:
24.50 × 8
196
Add both of her paychecks:
121.84 + 196
317.84
Divide the total by the total number of hours to find the average per hour:
317.84 ÷ 16
19.865
Round to nearest cent:
19.865 is about 19.87

Answer:
[tex]\frac{14}{19}[/tex]
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
[tex]\frac{7}{4} \div \frac{19}{8}[/tex]
Applying the fractions formula for division:
[tex]= \frac{7 \times 8}{4 \times 19}[/tex]
[tex]= \frac{56}{76}[/tex]
Simplifying 56/76, the answer is:
[tex]\frac{14}{19}[/tex]
I hope this helps! :)
Answer:
the answer is 14/19
change the mixed numbers to improper fractions then that becomes 7/4 and 19/8 then multiply across 7x8=56 and 19x4=76 that gives you 56/76
Simplifying 56/76,= 14/19

------------------------------------------------------------------
Si compro una manzana con 100 monedas, ¿cuántas monedas necesito para tener 1000 manzanas?
Answer:
100,000 coins
Step-by-step explanation:
We can use a ratio to solve
1 apple 1000 apples
------------ = ---------------
100 coins x coins
Using cross products
1x = 100 * 1000
1x = 100,000
We need 100,000 coins
Answer:
100,000 coins
Step-by-step explanation:
1 apple cost 100 coins
We want to find the amount of coins needed to get 1000 apples.
To do so we simply multiply the coins it takes to get 1 apple (100) by 1000
1000 * 100 = 100,000

Recall that in Linear Functions, we wrote the equation for a linear function from a graph. Now we can extend what we know about graphing linear functions to analyze graphs a little more closely. Begin by taking a look at Figure 8. We can see right away that the graph crosses the y-axis at the point (0, 4) so this is the y-intercept.
