Vineisha earned 110 percent on the science quiz which was about the phases of the moon.

Vineisha earned 22 out of 20 points on her science quiz over the phases of the moon

The percent earned can be calculated by dividing 20 by 22 and then multiplying the result by 100

22/20 × 100

= 1.1 × 100= 110

Hence the percent she earned on the quiz is 110%

Answer:

y intercept is (0,8) and the slope is 2 or 2/1 (its the same thing)

Step-by-step explanation:

i dont know the first answer sorry :( and to find the y-intercept its just where the line crosses the y-axis. slope is just rise over run and you go up 2 and to the right 1, so its 2/1 :) hope this helped!

Answer:

15:16 boys to girls

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

Distribute the 7 to get 273=14n+21

Subtract 21 to get 14n=252

Divide by 14 to get 18

Answer:

N=18

Step-by-step explanation:

Distribute~ 273=14n+21

Minus 21 to both sides~ 273-21=14+21-21

Divide your 14 to get rid of your variable~ 14n/14=252/14

Which would equal •18•

Answer:

Cross Multiply

Step-by-step explanation:

Cross multiplication can help answer these questions.

a. 3x-4/8=x+2/3

step 1- multiply 8 and (x+2), and 3 and (3x-4)

8x+16=9x+12

step 2- Subtract 8x on both sides

16=x+12

step 3- subtract 12 on both sides

4=x, or x=4

b. 3(2-r)/4=3+r/6

step 1- open parentheses

3(2-r)=6-3r

6-3r/4=3+r/6

step 2- cross multiply (put them into a equation without fractions by cross multiplying)

(6-3r) · 6= (3+r) ·4

step 3- multiply

36-18r=12+4r

step 4- solve

add 18r on both sides

36=12+22r

subtract 12 from both sides

24=22r

divide by 22 on both sides

24/22 or 12/11=r

r=12/11

c. 4p+3/8=p+2/4

step 1- cross multiply

(4p+3) · 4= (p+2)·8

step 2- open the parentheses

16p+12=8p+16

step 3- solve

subtract 12 on both sides

16p=8p+4

subtract 8p on both sides

8p=4

divide by  8 on both sides

p=4/8, or p=1/2

d. 2(a-7)/15=a+4/6

step 1- open parentheses

2(a-7) = 2a-14

2a-14/15=a+4/6

step 2- cross multiply

(2a-14) · 6 = (a+4) · 15

step 3- open parentheses

12a-84=15a+60

step 4- solve

subtract 60 on both sides

12a-144=15a

(the answer is -144 because a negative minus a negative such as -80-60=-144.

subtract 12a on both sides

-144=3a

divide by 3 on both sides

-48=a, or a=-48

Answer:

60 inches

Step-by-step explanation:

There are 12 inches in a foot.

There are 3 feet in a yard.

With this information, Joe is 5 feet away from finishing the race, but we need that answer in inches.

So if one foot equals 12 inches, we will simply multiply:

5ft × 12 in = 60 inches

Answer:

Step-by-step explanation:

First method: for (x+3)^2 if you multiply (x+3)(x+3) you get x^2+6x+9 which doesn't equal x^2+9

Second way:  plug in a variable for example (2+3)^2= 25 and 2^2+9=13 so 13 doesn't equal 25

Answer: y = -5x + 20

Step-by-step explanation:

Remember that : y=mx+b

y = (-5)x + b

Now you can plug your coordinates (-7,8) into that equation.

8 = (-5)-7 + b

Solve for b

8 = -12 + b

Add +12 to both sides of your equation:

20 = b

Now, your new equation is:

y = -5x + 20

Step-by-step explanation:

Answer:

x = 35º

Step-by-step explanation:

(x - 5)°+ (3x)º+ (x + 10)° = 180º

5x + 5 = 180º

5x = (180 - 5 )º

5x = (175 )º

x = 35º

Answer:

The Perimeter figure is: 21.42 mm

Step-by-step explanation:

The given figure consists of two parts:

1) Semicircle

2) Square

Determining the Perimeter of the Semicircle:

Given

Diameter d = 6 mm

Radius r = d/2 = 6/2 = 3 mm

In a semi-circle, the perimeter is made up of half the circumference (arc) of the circle and the diameter of the circle.

Perimeter = 1/2 × ( circumference of the circle ) + d

                = 1/2 × (2πr) + d

                = πr + d

                = 3.14(3) + 6

                = 9.42 + 6

                = 15.42 mm

Thus, the Perimeter of the semi-circle is: 15.42 mm

Determining the Perimeter of the Square:

Given

Length of a side = a = 2mm

Perimeter of square = 4a = 4(2) = 8mm

Thus, the Perimeter of the Square is: 8mm

Now, in order to determine the Perimeter of a complete figure, we need to add the Perimeter of the square and the perimeter of the semicircle and subtract 2 mm.

The reason why we need to subtract 2mm because one side of the square (2mm) is overlapped along the diameter of the semicircle.

Now,

Figure Perimeter = Perimeter of square + Perimeter of Semicircle -  2

                             = 8 + 15.42 - 2

                             = 21.42 mm

Therefore, the Perimeter figure is: 21.42 mm

Note: It seems you may have missed adding the correct choice there.

Answer:

x = 2

Step-by-step explanation:

2x - 3 = 9 - 4x ( add 4x to both sides )

6x - 3 = 9 ( add 3 to both sides )

6x = 12 ( divide both sides by 6 )

x = 2

The measure of {x} in the equation -3 = 9 - 4x is {x} = 3

A function is a relation between a dependent and independent variable. We can write the examples of function as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the value of {x} for the equation -

- 3 = 9 - 4x

The given equation is -

- 3 = 9 - 4x

We can write that -

- 3 = 9 - 4x

4x = 9 + 3

4x = 12

x = 3

Therefore, the measure of {x} in the equation -3 = 9 - 4x is {x} = 3.
