Answer:

Step-by-step explanation:

Use the area formulas to help.

Area of a triangle = 1/2bh

Area of a rectangle = lw

Area of the triangle:

6*5 =30 yds

30*0.5= 15 yds

Area of the rectangle:

7*12=84 yds

Area of the shaded region:

84-15=69 yds

Answer:

Answer:

(1,3)

Step-by-step explanation:

The image of (1, -3) is (1, 3).

There are two ways of reflection.

Along x-axis:

(x, y) – (x, -y)

Along y-axis:

(x, y) - (-x, y)

We have,

Point = (1. -3)

Reflected over the x-axis.

So,

(1, -3) = (1, -(-3)) = (1, 3)

Thus,

(1, 3) is the reflected image.

Answer:

The Equation to find the smallest integer =

4x + 6 = 170

The smallest integer = First integer = x = 41

Step-by-step explanation:

Four consecutive integers is represented by:

First Integer = x

Second Integer = x + 1

Third Integer = x + 2

Fourth Integer = x + 3

The sum of four consecutive integers is 170.

x + x + 1 + x + 2 + x + 3 = 170

The Equation to find the smallest integer =

4x + 6 = 170

4x = 170 - 6

4x = 164

x = 164/4

x = 41

Therefore:

The Equation to find the smallest integer =

4x + 6 = 170

The smallest integer = First integer = x = 41

Sure thing. Which question do you need help with? ill do the best i can.

Answer:

1kg of apple : €0.50

1kgof grapes : €1.20

Step-by-step explanation:

15kg of apples and 40kg of grapes costs €38

15kg of apples and 9kg of grapes costs €22.50

38 - 22.50 = 15.5

40 - 9 = 31

15.5 ÷ 31 = 0.5 ( 1kg of grapes )

0.5 × 3 = 1.5

7.5 - 1.5 = 6

6 ÷ 5 = 1.2 ( 1kg of apples )

a² + b² = c²

c² - b² = a²

10² - 8² = 36²

Square root of 36 = 6 inches

Answer:

6 in

Step-by-step explanation:

hypotenuse (h) = 10 in

base (b) = 8 in

perpendicular (p) = ?

we know that by using Pythagoras theorem

p = √h² - b²

= √10² - 8²

= √ 36

Answer:

the radius is 3.5 cm

the Diameter is 7 cm

Answer:

Possible dimensions are [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex] and [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]

Step-by-step explanation:

Given:

Volume of a cylinder is [tex]64\pi\,\,cm^3[/tex]

To find: Dimensions of a cylinder

Solution:

Let [tex]r,h[/tex] denote height of a cylinder.

Volume of a cylinder = [tex]\pi r^2h[/tex]

Therefore,

[tex]64\pi=\pi r^2h\\64=r^2h\\4^2\,4=r^2h[/tex]

One possible dimension can be [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex].

Also, [tex]64=r^2h[/tex] can be written as [tex]16(2^2)=hr^2[/tex]

So, another possible dimension can be [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]

Answer:

Answer:

x=5

x=−5

Step-by-step explanation:

5x^2+8 =133

Subtract 8 from both sides.

5x^2=133−8

Subtract 8 from 133 to get 125.

5x^2=125

Divide both sides by 5.

x^2=125/5

Divide 125 by 5 to get 25.

x^2=25

Take the square root of both sides of the equation.

x=5

x=−5

Answer:

b=40/63

Step-by-step explanation:

b= 7. 3b+-4

multiply both sides by 10

b*10=7.3b*10-4*10

refine

b*10=7.3b-40

subtract 7.3b from both sides

b*10-7.3b=7.3b-40-7.3b

simplify

-63b=-40

divide both sides by -63

-63b/-63=-40/-63

simplify

b=40/63
