what is the area of this figure?

Answers

Answer:

400 in²

Step-by-step explanation:

Consider the figure as a triangle on top of a parallelogram. The tic marks on the sides mean that the lengths with the same tic marks are equal.

The area of the parallelogram is 20×16=320

The area of the triangle is (20×8)/2= 80

Add the two areas: 320 + 80 = 400

Rewrite the formula to find the width of the base of the prism if the volume, length of the base, and height of the prism are already known.

Answers

Answer:

w = V/lh

Step-by-step explanation:

The volume of a rectangular prism is calculated using the formula V = lwh, where V is the volume of the prism, l and w are the length and width of the base of the prism, respectively, and h is the height of the prism.

Rewrite the formula to find the width of the base of the prism if the volume, length of the base, and height of the prism are already known.

volume of a rectangular prism,V = lwh

Where,

l = length of the base of the prism

w = width of the base of the prism

h = height of the prism

Rewrite the formula to find w

V = lwh

w = V/lh

That is,

width of the base of the prism = volume of the prism divided by length of the base of the prism multiplied by height of the prism

Evaluate the following algebraic expression, if (x = 5, y = 3)

Answers

Answer: 47

Step-by-step explanation:

simply substitute the constants with 5 and 3.

(5)^2 + 9(3) - 5 = 47

answer is 49. explanation: substitute 5 in for x and 3 in for y to get
5 squared+9(3)-5. 5 squared is 25. 9(3) is 27. 25+27-3 equals 49

In triangle Xyz the measure of angle YXZ is 14.5°, and the measure of angle XYZ is 75°. What is the measure of angle XZY in degrees

Answers

Answer:

90.5 degrees

Step-by-step explanation:

The sum of the angle in triangle XYZ is 180 degrees, hence;

m<XYZ + m<YXZ + <XZY = 180

Substitute the given angles

75 + 14.5 + <XZY = 180

89.5+m<XZY = 180

m<XZY = 180 - 89.5

m<XZY = 90.5 degrees

Hence the measure of angle XZY in degrees is 90.5 degrees

X^2+10x+22=13 1. Rewrite the equation by completing the square your equation should look like (x+c)^2 = d or (x-c)^2=d 2. What was the solution to the equation?

Answers

Answer:

(x+5)² = 16

Solution: -1 and -9

Step-by-step explanation:

Given the quadratic equation X^2+10x+22=13

Subtract 22 from both sides

X^2+10x+22-22=13-22

x^2+10x = -9

Complete the square

Add the square of half of coefficient of x to both sides

coefficient of x = 10

half of coefficient of x = 10/2 = 5

square of half of coefficient of x= 5² = 25

Add 25 to both sides

x²+10x + 25 = -9+25

(x+5)² = 16

Hence the required equation is (x+5)² = 16

(x+5)² = 16

square root both sides

√(x+5)² = √16

x+5 = √16

x +5 = ±4

x = +4 - 5 and -4-5

x = -1 and -9

Hence the solution to the equation is -1 and -9

Rose and Carl share a 24-ounce bucket of clay. By the end of the week, Rose has used 3 8 of the bucket, and Carl has used 1 4 of the bucket of clay. How many ounces are left in the bucket?

Answers

Answer:Quantity of Clay left = 9ounce

Step-by-step explanation:

Quantity of clay in the bucket = 24 ounce

Quantity of clay used by rose=3/8 of 24 ounce = 4 x 3 = 9 ounce

Quantity of clay used by Carl= 1/4 of 24 ounce = 6 ounce

Therefore Quantity of Clay left = Quantity of clay in the bucket - (Quantity of clay used by rose+ Quantity of clay used by Carl

24 ounce - ( 9ounce + 6 ounce )

24-15ounce

= 9 ounce

What are the restrictions for y for the following equation? X=10/5+y

Answers

Answer:

y = -5

Step-by-step explanation:

The restriction for the value of y is the value of the variable that will make the function undefined

The function is undefined when the denominator is zero i.e when 5 + y is zero

5+y = 0

y = 0-5

y = -5

Hence the restrictions is at when y = -5
