A write an equation for the amount of money they made from selling grapefruits and nuts
B Jada claims that the point of intersection is (50, 30) . Is she correct? What does the interception point mean in the situation

Answers

Answer:

A) The equation is x + 5y = 200

B) Jada is right, x is 50 and y is 30 The interception point is the amount of grapefruits and nuts they sold

it is where x + y = 80 and x + 5y = 200

Step-by-step explanation:

For question a, the equation would be:

x + y = 80, x = 80 - y

x + 5y = 200

substitute 80 - y for x

(80 - y) + 5y = 200

80 + 4y = 200

subtract 80 from both sides

4y = 120

y = 30

now for x:

x + 5(30) = 200

x = 50

Answer:

If you used π, 157.079632679 yards or 157.08 yards rounded to the hundredths place. If you used 3.14, the answer is 157 yards.

Step-by-step explanation:

The formula to find the perimeter of a circle is P=2×π×r.

Step 1: Find the radius. In this case, the radius is 25 yards as shown in the diagram.

Step 2: Since the formula only includes multiplication, you can multiply any of the factors. For simplicity, multiply your radius by 2 first. In this case, 2×25=50.

Step 3: Multiply your last number with π. In this case, 50×π=157.079632679 or 157.08 rounded the hundredths place. 50×3.14=157.

Step 4: You found the answer! Hope this helps.

Morgan saw 12 blue, 18 red, and 40 white cars drive by her house in 1 hour. What is the experimental probability that the next car that drives by her house will not be a white car? Round to the nearest hundredths.

Answers

Answer:

0.7 or 1 rounded to the whole number

Step-by-step explanation:

Add all of the numbers together (12+18+40=60)

And make your total as a fraction

There were 42 white cars and the total was 60 so the answer would be [tex]\frac{42}{60}[/tex] or 0.7 simplified (42 ÷ 60)

Hope this helps

It requires 1/4 of a credit to play a video game for one minute.
a. Emma has 7/8 credits. Can she play for more or less than one minute? Explain how you know.
b. How long can Emma play the video game with her 7/8 credits.

Answers

1/4 is the same as 2/8. Since emma has 7/8 credits, she can’t play another minute, since 7+2 would be 9 (bigger than 8).

She can play the video game for half a minute, because 1/8 (how much she can use) is half of 2/8, Which would be a whole minute
