Trapezoid STUV is similar to trapezoid NOPQ. What is the length of OP?

Answers

Answer:

F. 4 2/3 centimeters

Step-by-step explanation:

since the trapezoids are similar to each other, that means there is a common ratio between them. so taking into consideration the first trapezoid STUV when we compare that to NOPQ, OP comes out to be 4 and 2/3 centimeters. start by comparing the ratio of ST to NO and then move on to TU and then OP.

. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.

To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.

(which is the same as the number of sides).

540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.

Sum of Interior Angles of a Polygon

A pentagon has five sides, thus the interior angles add up to 540°, and so on.

What is the equation of the line that passes through the point
(

,

)
(7,2) and has a slope of
1
1?

Answers

Answer:

(y+2)= -3(x-7)

Step-by-step explanation:

We can use the slope-intercept formula to write this equation. The slope-intercept form of a linear equation is:

y = m x + b

Where m is the slope and b is the y-intercept value.

We can substitute the slope into the formula giving:

y = − 3 x + b

Next, we can substitute the values from the points in the problem for x and y and solve for b :

− 2 = ( − 3x 7 ) + b

− 2 = − 21 + b

21 − 2 = 21 − 21 + b

19 = 0 + b

19 = b

We can now substitute the slope from the problem and the value for b we calculated into the formula to write the equation.

y = − 3 x + 19

Another process is to use the point-slope formula. The point-slope formula states:

( y − y 1 ) = m ( x − x 1 )

Where m is the slope and ( x 1 , y1 ) is a point the line passes through.

Substituting the slope and values from the points in the problem gives:

(y − − 2 ) = − 3 (x-7)

( y + 2 ) = − 3 ( x − 7 )

The slope would be 3/4
Explanation: you would first substitute in the values of x and y into the equation to find the slope, you then would simplify the numerator by multiplying -1 and -2 over 0-(-4) and subtract 2 from -1 and after this you would simplify the denominator by multiplying -1 by 4 and after you get your result you subtract 4 from 0 and you would then divide your 2 negative values results in a positive value which is m=3/4

-2/3 x - 1 =19 yeah its -2over3 with x to the right then -1 = 19

Answers

Answer:

x = 30

Step-by-step explanation:

Given the expression

-2/3 x - 1 =19

We are to find the value of x

Add 1 to both sides

2/3 x -1 +1 = 19+1

2/3 x =20

Multiply

2/3x × 3 = 20×3

2x = 60

x = 60/2

x = 30.

Hence the value of x is 30

Lina has five more than seven times as many pictures as photo albums. If she has 75 pictures, how many photo albums does she have?

Answers

Answer:

photo albums = x

pictures =75( seven times of albums +5)

seven times of x is 7x and +5

7x +5 = 75

7x= 75-5

7x = 70

x=70÷7

x =10

x = 10 = photo albums

Denise makes three times as many chocolate cupcakes as vanilla cupcakes. She also makes three dozen strawberry cupcakes. If Denise makes 132 cupcakes, how many dozen chocolate cupcakes does she make?

Answers

Answer:

6 dozens

Step-by-step explanation:

Vanilla, v = x

Chocolate, c = 3x

Strawberry, s = 3 dozens = 36

Total cupcakes = 132

Hence,

x + 3x + 36 = 132

4x = 96

x = 96 / 4

x = 24

Chocolate = 3 * 24 = 72

Dozens of chocolate = 72 /12 = 6 dozens

Ashley and Gabby bought lunch from the food trucks on Sugar Day. Ashley bought 3 tacos and a drink for $7. Gabby bought 2 drinks and 2 tacos for $8. How much does 1 taco cost? A taco costs__

Answers

Answer:

$1.5

Step-by-step explanation:

This would be solved using a simultaneous equation

let tacos = t

drink = d

3t + d = 7 -- eqn 1

2t + 2d = 8 -- eqn 2

Multiply equation 1 by 2 to derive equation 3

6t + 2d = 14 eqn 3

Substract equation 2 from equation 3

6t + 2d = 14 -- eqn 3

2t + 2d = 8 -- eqn 2

= 4t = 6

solve for t

6/4 = 1.5

= $1.5
