Answer:
1 / 180 + 1 / t = 1/84
t = 157.5 minutes
Step-by-step explanation:
3hrs = 180 minutes
1.4 hours = 84 minutes
your rate + friend's rate = rate together
1 lap in 180 min + 1 lap in t min = 1 lap in 84 min
The equation is
1 / 180 + 1 / t = 1/84
subtract 1/180 from both sides
1/t = 1/84 - 1/180
1/t = 0.006349206349
multiply both sides by t
1 = 0.006349206349t
Divide both sides by 0.006349206349
1 / 0.006349206349 = t
157.5 = t
t = 157.5 minutes

June, Gavyn and Alex share some sweets in the ratio 5:3:2. June gets 42 more sweets than Alex. How many sweets does Gavyn get?
Answer:
42 sweets
Step-by-step explanation:
The ratios are 5 : 3 : 2 = 5x : 3x : 2x (x is a multiplier )
June gets 42 more sweets than Alex , then
5x = 2x + 42 ( subtract 2x from both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Gavyn = 3x = 3 × 14 = 42 sweets
Answer:
42 sweets.
Step-by-step explanation:
First work out the number of parts:
5 + 3 + 2 = 10.
So June gets 5/10 = 1/2 of the sweets.
Alex gets 2/10 = 1/5.
Gavyn gets 3/10.
If the total number of sweets was x, then:
1/2 x - 1/5 x = 42
5/10x - 2/10 x = 42
3/10 x = 42
x = 42*10/3 = 140.
So Gavyn has 3/10 * 140 = 42.

Answer:
The correct answer is H: c=2A/h-b
Step-by-step explanation:
A=1/2(b+c)h
Multiply both sides by two: 2A=(b+c)h
Divide both sides by h: 2A/h=b+c
Subtract b: 2A/h+b=c

The new pastry chef at Jackson's Bakery specializes in Sheet cakes for parties. She sold 17 small, 11 medium, and 20 large sheet cakes in one week. How much money did Jackson's Bakery make in one week from sheet cakes?
Answer: $2,245 (I know it for this one but not the next one)
How many people would all of the sheet cakes sold in problem 3 feed?
--------------------------------------------------------------------------------------------------------
(Dont need to tell me the answer just tell the steps I need to do)
Answer:
The chef sold 17 small sheet cakes. One small sheet cake can feed 12 people, so the small sheet cakes she sold can feed 17*12 people, which is 204 people. Do this for the medium and large sheet cakes as well, and add them up, and you'll get the answer.
Step-by-step explanation:
Hope this helps!
Answer:
1086
Step-by-step explanation:
1. 7x12= 204(small cakes)
2. 11x22=242(medium cakes)
3.20x32=640(large cakes)
4. add all of the products up
so: 204+242+640
= 1086
This should be correct.
The town of Lantana needs $14,000 for a new playground Lantana elementary school raised 5358, Lantana Middle School raised $2,834 and Lantana High school raised $4132. about how much more do they need to raise? Choose the best estimate.

2. 2,000
3. 3000
4. they already raised enough money.
Answer: The answer is actually 1,676. But you can estimate it to 2,000. so the town of Lantana would have about 2,000 dollasrs left to raise to reach there goal.
Step-by-step explanation:
You would first make sure you add all the number like 5,358+2,834+4,132. And once you get you answer you subtract 14,000 from the number you got!

Julie has a jewelry box shaped like a cube. The volume of the jewelry box is V cubic inches. Use this information to answer Questions 6 and 7. Write an expression that represents the edge length of Julie's jewelry box in inches.
Answer:
s = ∛V
Step-by-step explanation:
The relationship between edge length (s) and volume (V) of cube is ...
V = s³
Taking the cube root of both sides of this equation gives you an expression for the edge length:
s = ∛V
_____
Additional comment
The units of s will be the cube root of the units of V. If V is in cubic inches, then s is in inches.

Identify the parent function for the function g(x) = x2 - 4 based on its function rule.
Then graph g and identify the transformation of the parent function that it
represents.
linear; translation up 4 units
quadratic; translation up 4 units
quadratic; translation down 4 units
O
linear; translation down 4 units
Answer:
Parent function is g(x) = x² a quadratic
Step-by-step explanation:
quadratic; translation down 4 units
-4 means the vertex will move down 4
The transformation of the parent function that represents translation down 4 units. Therefore, quadratic; translation down 4 units.
The given function is g(x)=x²-4.
What is the parent function?A parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.
Quadratic; translation down 4 units:
The parent function of the quadratic family is f(x) = x2. A transformation of the graph of the parent function is represented by the function g(x) = a(x − h)² + k, where a ≠ 0.
The transformation of the parent function that represents translation down 4 units. Therefore, quadratic; translation down 4 units.
