I need help on this question I got 145.13 but i dont know what I did wrong

Answer:

a) 3a + 8b = 93

Hope this helps!

Answer:

Total students = 460+320+165=945

Key stage 3 ... asafraction = 460 divide by 945

the number in a sample of 100 = 460 divide by 945 x 100= 48.67

So 48 or 49 (are both, acceptable answers).

Answer:

14.3 yd

Step-by-step explanation:

apply the pythagorean Theorem formula:

= sqrt(14^2 +3^2)

= sqrt(205)

roughly 14.3 yd

Answer: Ms. Basalyga won $2,000 in a math contest. She had to pay 13.5% of that amount in taxes to the government. How much did Ms. Basalyga pay in taxes?

:13.5/100×2000=270

Step-by-step explanation

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept

1) Determine the slope (m)

To find the slope, take two points from the table, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] and plug them into the following equation to solve for m:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug m into [tex]y=mx+b[/tex] .

2) Determine the y-intercept (b)

Take any point given in the table and plug them into [tex]y=mx+b[/tex] (along with the slope that you solved for earlier) as [tex](x,y)[/tex]. Solve for b. Plug b back into [tex]y=mx+b[/tex] along with the slope.

Answer:

Number of hours= 20 hours

Step-by-step explanation:

Giving the following information:

Net savings (babysitting)= 250 - 110= $140

Rate per hour= $7

To calculate the number of hours that Melissa worked as a babysitter, we need to use the following formula:

Number of hours= net savings / rate per hour

Number of hours= 140 / 7

Number of hours= 20 hours

have a great day!!

The 28.3 ft is closest to the length of the walkway. the answer will be Option B. 28.3 ft

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

It is given that Mr. Ammons is constructing a walkway through his rectangular Garden. The walkway runs diagonally as shown in the diagram.

We need to find the length of the walkway.

Using Pythagoras Theorem;

[tex]15^2 + 24^2 = x^{2} \\\\x^{2} = 225 + 576\\\\x^{2} = 801\\\\x = \sqrt{801} \\\\x = 28.30[/tex]

Therefore, 28.3 ft is closest to the length of the walkway. answer will be Option B. 28.3 ft

Answer:

A is the answer

Step-by-step explanation:

6 times 3.14 is 18.84

Given,

Diameter of circle = 6 in.

As we know that radius is half of diameter.

Radius = 6 × 1/2 = 3 inches

Now,

[tex] \sf Circumference \: of \: circle = 2 \pi \: r[/tex]

[tex] = \: 2 \times \dfrac{22}{7} \times 3[/tex]

[tex] = \dfrac{44}{7} \times 3[/tex]

[tex] = \dfrac{132}{7} [/tex]

[tex] = 18.84\: in.[/tex]

Hence,option ( a ) is correct.

The anwer is 62 degrees

Step-by-step explanation:

angle x and the angle with a measure of 62 degrees are alternate exterior angles therefore they are congruent
