Find the area of the triangle

Answer:

105 students

Step-by-step explanation:

The computation of the number of students left the school is given below:

Let us assume the total students be  x  and 100%

Left percentage = 84%

Remaining percentage = 100% - 84% = 16%

Now according to the question

16% of x = 20

0.16x = 20

x = 20 ÷ 0.16

x = 125

Total students 125

Those who left is

= 84% of 125

= 105 students

Answer:

Joshua's account had a greater change.

Step-by-step explanation:

Both accounts had $100

Joshua's account now has $67.25 which means he used $32.75

Crystal's account now has $131.97 which means he saved $31.97.

Joshua had a greater change of balance.

Answer:

4) The error made was that you were supposed to multiply 5 and 2. The answer is supposed to be 43.

5) B) 18

6) 18

7) B) 20

8) B) 28

Step-by-step explanation:

4)

36 - 3 + 5 · 2

36 - 3 + 10

43

5)

3(7) - 3 = 18

6)

3(2) + 2(4) + 4 =

6 + 8 + 4 =

18

7)

24 ÷ 3 + 12 = 8 + 12 = 20

8)

5(6) - 2 = 30 - 2 = 28

Answer:

tall candles = 39

Short candles = 52

Step-by-step explanation:

let tall candles be x

and short candles be y

No. Of candles sold = x + y =91

Money made from candles will be equal to = 8x + 5y = $572

These both are simultaneous linear equations.

x + y =91 ( multiply by 5)

5x + 5y = 455

8x + 5y = $572

Subtract them:

-3x = -117

x = -117/3

x = 39

put value of x in

x + y = 91

39 + y = 91

y = 91 - 39

y = 52

x shows tall candles so they are 39

y shows short candles so they are 52

Skewed Right I think. I'm not sure but try it

Answer:

C. Skewed Left

Step-by-step explanation:

Because the first 2 age group have minimal runners than the next 3 age groups spikes and the last 4 are very low once again. the spike occurs relavity near the beggining so if graphed it would be skewed left.

Step-by-step explanation:

The equation of an exponential function will be y = 7.68 × 2.5ˣ.

What is equation of line?

The equation of line with slope m and passes through the point (x₁, y₁) is calculated as;

y - y₁ = m (x - x₁)

Given that;

An exponential function passes through the points (2, 48) and (5, 750).

Now, The exponential function is;

y = abˣ

Where, a and b are unknowns.

Hence, For the point (2, 48), we get the equation;

48 = ab² .. (i)

And, For the point (5, 750), we get;

750 = ab⁵   .... (ii)

Solve the equation (i) for value of a, we get;

48 = ab²

a = 48/b²

Substitute in equation (ii);

750 = ab⁵

750 = (48/b²) b⁵

750 = 48 b³

b³ = 750/48

Take cube root both side;

b = 5/2

Hence, a = 48/b² = 48/(5/2)²

a = 48 × 4 / 25

a = 7.68

Thus, After substitute the value of a and b we get the exponential equation as;

y = 7.68 × 2.5ˣ

Therefore, The equation of an exponential function will be,

⇒ y = 7.68 × 2.5ˣ.

Hope this helped!!!

Answer:

24p - 35

Step-by-step explanation:

1 + 4 ( 6p - 9 ) (multiply 4 x 6p = 24p and 4 x 9 = 36 )

1 +  24p - 36   ( subtract 1 on both sides on 1 and 36)

-1              -1     ( 36 - 1 = 35 )

Answer:

x = 65

Step-by-step explanation:

Exterior angle thm states the 2 interior angles of a triangle are equal to the exterior angle:

x + 48 = 2x - 17

x - 2x = -17 - 48

-x = -65

x = 65
