Answer: The answer is option C: 23 square inches

Step-by-step explanation: The two rectangles are given as

ABCD with area of 90 and one side equals 10. That means the other side measures

Area = L x W

90 = 10 x W

90/10 = W

W = 9.

The second rectangle has a side measuring 5 inches and both rectangles have been described as similar. This means there is a common ratio between all sides of both figures.

If AB in rectangle 1 equals 10 inches, and XY in rectangle 2 equals 5 inches, the ratio of both rectangles is given as

Ratio = 10:5

Ratio = 2:1

Hence for rectangle 2, if line AB equals 9, then line WX equals

2/1 = 9/WX

By cross multiplication we now have

WX = 9/2

WX = 4.5

Therefore, the area of rectangle WXYZ is computed as

Area = L x W

Area = 5 x 4.5

Area = 22.5

Approximately to the nearest integer,

Area ≈ 23 square inches

A football quarterback goes for a two-point conversion when the ball is within 10 yards of the end zone. During the game, he has

Crank

Answer:

$P=0.075$ , $P=7.5\%$

Step-by-step explanation:

We look for the probability that the player fails the first attempt and also fails the second attempt.

We know that the probability that the quarterback fails the first attempt is:

$P(1) = 0.5$

We know that the probability that the quarterback fails the second attempt after failing the first is:

$P(2|1) = 0.15$

Then the probability of failure of both attempts is:

$P(2|1)=\frac{P(1\ and\ 2)}{P(1)}$

$P(1\ and\ 2)=P(1)*P(2|1)$

$P(1\ and\ 2)=0.5*0.15$

$P(1\ and\ 2)=0.075$

How many roots does the graphed polynomial function have?

TiliK225 [7]

To start, note that the roots of a function have to do with how many times the function passes through the x-axis.

When you look at the graph above, notice that it passes through the x-axis 3 times, at the points (-6,0), (-4,0), and (3,0).

Knowing this, you can conclude that your answer would be choice B.)3

Solve problems about a lemonade stand, and write about the solutions. Cups $2 Lemons $8 Sugar $3 Juan wants to start a lemonade

Fofino [41]

Answer:

$3 from his pockets

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

To begin solving this problem we need to first calculate how much money all the supplies will cost. We do this buy adding up the prices of each individual supply. Like so,

$2+8+3 = 13$

Now we can see that the total amount of the supplies is $13. Since his mom loaned him $10 we can subtract that from the total cost.

$13-10 = 3$

Finally, we can see that Juan would need to pay a total of $3 from his pockets to be able to buy all the ingredients.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
