Answer:

D

Step-by-step explanation:

Subtract 30 and 16. Cross out 0 and make it a 10 and 10-6= 4 then take 1 from 3 and make it a 2 and 2-1=1. It will all equal up to 14!

Answer:

8x+30+4x+18=180

12x+48=180

180-48=12x

132=12x

x=132/12

x=11

Answer:

mean=42

SD=7.8

X=54

Z=(X-u)/SD

Z=(54-42)/7.8=12/7.8

=1.54

Answer:

D. 10

Step-by-step explanation:

Assuming that <COA is a right angle, we can say that the two given angles are complementary

complementary angles are angles that add up to 90 degrees

this means we can create this equation: 3x + 46 + 14 = 90

so subtract 46 and 14 from 90: 3x = 30

divide both sides by 3: x = 10

Answer:

132 units

Step-by-step explanation:

the area of triangle = 1/2 × 6 × 8 = 24 units >>>1

the area of the rectangle = 3 × 8 = 24 units >>>2

the area of rectangle(2) = (21-(9+3)) × 8 = 9 × 8 =72 units >>>3

the area of triangle(2) = 1/2 × 3 × 8 = 12 units >>>4

then , from 1 , 2 , 3 and 4 the area of the figure = 24+24+72+12 = 132 units

Answer:

it's answer is 132

hope it helps you

Answer:

Parallel lines

Step-by-step explanation:

The standard form of equation of a straight line is expressed as:

y = MX+c

m is the slope

Given the equations

y = 7x – 2

On comparison;

m = 7 i.e the slope of the line is 7

For the line 14x – 2y = 3

First write in standard form

-2y = -14x +3

y = -14x/-2 + 3/-2

y = 7x- 3/2

Hence the slope is also 7

Since both equations have the same slope hence they are parallel lines(Parallel lines have the same slope)

Answer:

the slope is m= 5/31 :)

Answer:

I think the answer is B. The equation has infinitely many solutions.

Step-by-step explanation:

4(3x + 4) = 15x + 12 - 3x + 4

*group like terms so 4(3x+4) = 15x - 3x + 12 + 4

*add similar elements 15x - 3x = 12x

*add the numbers 12 + 4 = 16

*Expand to 12x + 16 - 16 = 12x + 16 - 16

*You simplify 12x = 12x

*Subtract 12x from both sides

*Then Simplify which is 0

Which means Both sides are equal to 0

Step-by-step explanation:13+4>а>13-4

a>9

Given:

1 set requires 4 couples 8 dancers.

Total number of people at a square dance = 250.

To find:

The greatest number of sets possible at the dance.

Solution:

We have,

Total people = 250

1 set = 8 people.

[tex]\text{Number of possible sets}=\dfrac{\text{Total people}}{\text{People required for 1 set}}[/tex]

[tex]\text{Number of possible sets}=\dfrac{250}{8}[/tex]

[tex]\text{Number of possible sets}=31.25[/tex]

Number of possible sets cannot be a decimal or fraction value. So, approx. the value to the preceding integer.

[tex]\text{Number of possible sets}\approx 31[/tex]

Therefore, the number of possible sets at the dance is 31.

Answer:

A

Step-by-step explanation:

Let's say the surface of the pool is 0, and the diver 4 meters above represents +4, and the diver 5 meters below represents -5. Which number is closer to 0? It's 4! 4 is 4 numbers away from 0, meanwhile 5 is 5 numbers away from zero, 4 is closer to 0!

Answer: I put b. Parallelogram

Step-by-step explanation:

Answer:

B) 5.7

Step-by-step explanation:

The area of a square is found by multiplying its sides. Since a square has perfectly equal side lengths, you know that the square root of the area is equal to the side lengths. The area is 33. The square root of 33 is roughly 5.7. Hope that helps!

Answer:

7/2 and 3

Step-by-step explanation:

using quadratic formula

{-(-13) +- √(-13)^2 - 4(2)(21) } /2(2)

-(-13)+1 / 4 = 7/2

-(-13)-1 / 4 = 3

Answer: x = 7/2 and 3

Step-by-step explanation: Rewrite and factor

2x² —13x + 21 = 0

(2x - 7)(x - 3) = 0

2x - 7 = 0. x = 7/2

x - 3 = 0 x = 3

Answer:

x>10/4

Step-by-step explanation:

When you combine like terms, you get 10>4x and then divide by 4 and you get x>10/4. To plot this, you put an open point on 10/4 and highlight everything to the right of it with an arrow.
