Answer:

80m²

Step-by-step explanation:

area of rectangle-&10m×6m=60m²

10m-6m=4m

10m×4m=40m²

area of triangle->40m²÷2=20m²

area->60m²+20m²=80m²

Answer:

18.6inches

Step-by-step explanation:

Given the length of a side of a pentagon to be 6 inches.

If this length is dilated by a factor of 3.1, the new length will be;

New length = Old length * dilation factor

New length = 6 * 3.1

New length = 18.6inches

Hence the length of each side of the dilated pentagon is 18.6inches

Answer:

So the answer is 2^-3

Step-by-step explanation:

The principle is the same no matter what the base.

Log_2 (7) + Log_2(3/28) - Log_2(6)

+ means multiply

- means divide

Log_2(7 * 3/28 /6)

Log_2(7/6 * 3/28)

Log_2(1/2 * 1/4)              3 divides into 6 twice. 7 divides into 28 four times

log_2 (1/8)

This is equivalent to 2^(-3)

Yes you are correct! This equation will make a parabola. The width when the arch is at ground level would be the x-intercepts, or zeros, of the parabola.

The vertex point is (0,12)

the axis of symmetry is 0

The zeros are (-4,0) and (4,0)

using the zeros take away the negative because something cant be negative feet wide and add the numbers together (4+4)

Answer:

70

Step-by-step explanation:

since you are solving for the middle angle, you solve for the average for both angles on the side

(112+28)/2=70

x=70

Answer:

Step-by-step explanation:

A line is expressed as y=mx+b where m=slope and b=y intercept. As long as we have two points we can solve the equation of that line.

y=mx+b

For the top line I found two points (5,200) and (30,325)

m=(y2-y1)/(x2-x1)=(325-200)/(30-5)=125/25=5

y=5x+b, using point (5,200) we can solve for b

200=5(5)+b, b=200-25=175 so the line is

y=5x+175

For the bottom line we have points (5,50) and 10,100)

m=(100-50)/(10-5)=50/5=10

y=10x+b, using point (5,50) we have

50=10(5)+b, b=50-50=0 so

y=10x

Answer:

The Reach for a Dream Foundation received R33000, NSPCA received R44000, and Smile received R55000.

Step-by-step explanation:

Total money for charity = R132,000

Ratio:

3 : 4 : 5

Charities:

The Reach for a Dream Foundation : NSPCA : Smile

x : y : z

3x + 4y + 5z = R132000

Charity 1 = Charity 2 = Charity 3

x = y = z

3x + 4x + 5x = R132000

x = 11000

The Reach for a Dream Foundation:

3(11000) = R33000

NSPCA:

4(11000) = R44000

Smile:

5(11000) = R55000

Double Check:

R33000 + R44000 + R55000 = R132000

Answer:

b=8

Step-by-step explanation:

Perpendicular lines are negative and reciprocal; when you multiply the slopes together, the result is -1.

we are given the line y=-3x-5

we need to find the slope of the new line. To do that, we can use this equation:

-3m=-1

divide by -3 on both sides

m=1/3

so the slope of the perpendicular line is 1/3

We can write our line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, which is what we need

so far our equation is:

y=1/3x+b

we need to find b

we can substitute the point (-3,7) into the equation, since the line will pass through it to solve for b

so:

7=1/3(-3)+b

7=-1+b

8=b

so the y intercept of the line is 8; as a point it's (0,8)

the answer is 0.85 of 2.38 ÷ 2.8

Answer:

0.85

Step-by-step explanation:

[tex]\frac{2.38}{2.8} =\frac{2.38}{2.8}*\frac{100}{100}=\frac{2.38*100}{2.8*100}=\frac{238}{280}\\\\\frac{238}{280}=\frac{238}{280}/\frac{14}{14} =\frac{238/14}{280/14}=\frac{17}{20}\\\\\frac{17}{20}=\frac{17/2}{20/2}=\frac{8.5}{10}=0.85[/tex]

Answer:

x=11°

<Bec = 33°

<Ced = 39°

Step-by-step explanation:

That's a right angle so it would be 90 degrees angle.

18+3x+4x-5=90

Lets simplify it to make it easier to work out by collecting like terms.

First all the variable 3x+4x=7x

Then the numbers 18+-5=13

13(-13)+7x = 90(-13)take away 13 from both sides

(Opposite operators EG, Add becomes subtract)

7x = 77 then divide 7 from both sides

x=11

Then work out

3x11=33 degrees

4x11=44-5=39 degrees

To double check 39+33+18=90 degrees

the answer is A. fggggggggtggg
