1. C
L=1/2(Pxl)
L=1/2(20x9)
L=1/2(180)
L=90

SA=1/2(Pxl)+B
SA=90+5^2
SA=115

B, A, C, B.

To help answer this question, Deigo wrote the division equation 3/4 divided by 2/5. Explain why this equation does not represent
Mars2501 [29]

Answer:

The fraction of the rain filled in the gauge will be =  \frac{8}{15}

Diego wrote the division equation incorrectly.

It must be given as \frac{2}{5} divided by \frac{3}{4} .

Step-by-step explanation:

Given:

After \frac{3}{4} of an hour of rain the rain gauge is \frac{2}{5} filed.

To find the fraction of the rain that will be filled in the gauge if it continues to rain at the same rate for 15 more minutes.

Solution:

15 minutes in hours will be = 15\ min \times \frac{1\ hour}{60\ min} = \frac{1}{4} of an hour.

Given that it has rained for \frac{3}{4} of an hour, and it continues to rain for  \frac{1}{4} of an hour more.

Thus, total time of rain will be = \frac{3}{4}+\frac{1}{4}=\frac{4}{4}=1\ hour

Using unitary method to find the fraction of rain filled in the gauge after 1 hour of rain.

If in  \frac{3}{4} of an hour of rain the rain gauge is \frac{2}{5} filed.

Thus, in 1 hour of rain the gauge will be filled by = \frac{2}{5}\div \frac{3}{4}

To divide fractions, we take reciprocal of the divisor and replace division by multiplication.

⇒ \frac{2}{5}\times\frac{4}{3}

⇒ \frac{8}{15}

Thus, the fraction of the rain filled in the gauge will be =  \frac{8}{15}

Diego wrote the division equation incorrectly.

It must be given as \frac{2}{5} divided by \frac{3}{4} .

Write equation for the graph
Whitepunk [10]

Answer:

the line goes through 1 from x axis and in the same time the line continue his trip and goes through 4 from y axis

so now we have rule to use to find the equation

y/4+x/1=1

y/4=1-x

y=4-4x

and this is the equation
