Answer:

E) 551.7 ft Squared

Step-by-step explanation:

First find the area of the rectangle. 15 x 25 = 375. Then remove the rectangle so your left with a circle with a diameter of 15. Find the area of the circle. Pi x R squared. Pi x 7.5 squared = 176.7 . Then add the areas together. 375 + 176.7 = 551.7

Pleaseeee i will mark brainlesttttt solve this system of equations 12x−15y=14 8x−15y=6

Sphinxa [80]

Answer:

x = 2 and y = $\frac{2}{3}$

Step-by-step explanation:

To solve this system of equation, we will follow the steps below;

We will use both elimination and substitution method to solve this system of equations

12x−15y=14 ------------------------------------------------------------------------(1)

8x−15y=6 --------------------------------------------------------------------------(2)

subtract equation (2) from equation (1)

(By doing that the y variable will be eliminated)

4x = 8

Divide both-side of the equation by 4

4x/4 = 8/4

x = 2

Substitute x =2 into equation (2) and then solve for y

8x−15y=6

8(2)−15y=6

16 - 15y = 6

subtract 16 from both-side of the equation

16 - 16- 15y = 6-16

-15y = -10

Divide both-side of the equation by -15

-15y/-15 = -10/-15

y = $\frac{2}{3}$

x = 2 and y = $\frac{2}{3}$

PLEASE HELP! 25 POINTS!

Marizza181 [45]

Step-by-step explanation:

Step 1: Convert the mixed number into an improper fraction

$1 \frac{5}{7}$

$\frac{7}{7}+ \frac{5}{7}$

$\frac{12}{7}$

Step 2: Multiply to find the area

$\frac{5}{6}*\frac{12}{7}$

$\frac{60}{42}$

Step 3: Convert into a mixed number

$\frac{60}{42}$

$\frac{42}{42} + \frac{18}{42}$

$1 \frac{18}{42}$

$1\frac{3}{7}$

Answer: $1\frac{3}{7}$

Find the values of x and y if (2x + y, 2) = (1, x - y).

m_a_m_a [10]

Answer:

We have, 2x+y=3 .......(1)

xy=1....(2)

In equation (2), we get

..........(3)

y put in the equation (1)

2x+

+1=3x

−3x+1=0

−3x−1x+1=0

2x(x−1)−1(x−1)=0

x=1, x=

We take the value of x=1

x value put in equation (1)

2(1)+y=3

y=3−2

y=1

x=1

x and y value put (x+y)

x−y

=(1+1)

(1−1)

Hence, this is the answer
