A triangle has a base length of 12 inches and a height of 14 inches. From that
information, answer the following:
What is the area?

Answer:

86%

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

The sum for the class is calculated as

[tex]\frac{sum}{30}[/tex] = 70 ( multiply both sides by 30 )

sum = 2100

The sum of the 20 boys is

[tex]\frac{sum}{20}[/tex] = 62 ( multiply both sides by 20 )

sum = 1240

The sum for the 10 girls is therefore 2100 - 1240 = 860

Thus the mean mark for the girls is

mean = [tex]\frac{860}{10}[/tex] = 86%

Answer:

The area of a shape is the amount of two-dimensional space that it covers. The ratio of the perimeter to the area of a shape is simply the perimeter divided by the area. This is easily calculated.

Answer:

[tex]900m^3[/tex]

Step-by-step explanation:

Volume is found when you multiply length by height by width.

So, in this case, 18 times 10 times 5.

[tex]18*10*5=180*5=900[/tex]

So, [tex]900m^3[/tex] is the answer

Answer:

The quotient is  3 and [tex]\frac{3}{4}[/tex].

Step-by-step explanation:

To find the quotient of the division (which is just the solution, really), we have to solve the division itself:

[tex]\frac{\frac{3}{4}}{\frac{1}{5}}[/tex]

[tex]= \frac{3 \cdot 5}{1 \cdot 4}[/tex]

[tex]= \frac{15}{4}[/tex]

Now that we know the quotient, we can look at the question itself to find it requires from us an answer with a whole number in it.

Therefore, we transform the fraction as thus:

[tex]\frac{15}{4}[/tex]

[tex]= 3 \frac{3}{4}[/tex]

Therefore, the final answer is 3 and [tex]\frac{3}{4}[/tex].

Answer:

She will have 17 and 3/5 cups of green paint.

Step-by-step explanation:

1. Identify your key factors:

Yellow paint: 4/5

Blue paint: 4/5

Mixes: 11 batches.

2. Arrange and solve:

4/5 x 11/1 = 44/5 x 2/1 = 88/5

[4/5 is the same amount for eithr paint so multiplying it by 2 is will give the same result, it's just less work.]

3. Simplify:

Answer:

80 degrees

Step-by-step explanation:

since ac and bc equal each other, it is an isosceles triangle. due to that, the measure of angle a and b are 50. so the measure of angle c is 80. due to some theorem, angle ecd is equal to angle acb. so ecd = 80

y + 1 = -1/4x + 2

y = -1/4x + 1

Answer:

314 * 2

Step-by-step explanation:

Answer:

y = -x + 9

Step-by-step explanation:

The line that passes through the points (-2,4) and (0,6) has a slope of 1, and a y intercept of 6. The equation to the first line is y = x + 6. and perpendicular lines always have the opposite, reciprocal slope of the other line. So the slope for the second line would be -1. A line with the slope of -1 and a point of (5,4) would contain the points (5,4) , (4,5) , (3,6) , (2,7) , (1,8) , and (0,9) , which is the y intercept for the second line. So the equation for the second line would be y = -x + 9

Final result :

3 • (8yx + 18y - x)

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line is y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope of the line using the points (1, 1) and (2, 4).

Slope = [tex]\frac{rise}{run}[/tex]

          = [tex]\frac{4-1}{2-1}[/tex]

          = 3

Based on the graph, the y-intercept is (-2) so the equation of the line is:

y = 3x - 2

7x+4=3x-20

Subtract 3x to the left.

4x+4=-20

Subtract 4 to the right.

4x=-24

Divide -24/4 to isolate variable "x".

x=-6

Plug it back it to prove the solution.

7(-6)+4=3(-6)-20

-38=-38

Answer:

7x+3=-25+3x

minus 3 on both sides

7x=-28+3x

minus 3x both sides

4x=-28

divide 4 both sides

x=-7

the number is -7
