Answer:

58.5

Step-by-step explanation:

Split the figure into three shapes; square, trinagle, and rectangle.

Square is 3 ⋅ 3 = 9

Triangle's sides are 3 and 11 so...

(3 ⋅ 11)/2 = 16.5

Rectangle is 3 ⋅ 11 = 33

Once you have the area of all the figures, you just add them together so...

9 +16.5 + 33 = 58.5

Answer:

area of the figure= 58.3ft²

Step-by-step explanation:

area of the figure= area of trapezoid+ area of a rectangle

area of the figure= [½(a+b)*height]+ (length*breadth)

area of the figure= [½(3+14)*3]+ (11*3)

area of the figure=25.3+ 33

area of the figure= 58.3ft²

Answer: 34 questions right

Turn 85% into a decimal so .85 then multiply by 40 to get 34

Step-by-step explanation:

Answer:

34

Step-by-step explanation:

*A triangle has an interior angle of 180 degrees

We know that one of the angle is 112 degree

180 - 112 = 68 degrees

We also know that the triangle is an isosceles triangle which means both sides and both angles are the same ( we can determine that it's an isosceles because of the two lines)

68 / 2 = 34

R = 34 degrees

T = 34 degrees

S = 112 degrees

Answer:

Step-by-step explanation:

okay don't feel bad, you actually got it right, let me help you with some holes!

You calculate slope by the rise over run. These people are confusing you a bit - do problem 2 then 1

the vertical change is -1 horizontal change is 3 so by rise/run=-1/3

-1/3 is the slope

for the second problem this is confusing but just read and try to analyze

vertical change/horizontal change = 5-4/0-3= 1/-3(or -1/3)

The y intercept is the point where the line hits the y axis, so at point (0, 5)

The function is y=mx+b

m is the slope

b is the y intercept

so y=-1/3x+5

Answer:

9x + 15 < -12 =x<−3

Step-by-step explanation:

Step 1: Subtract 15 from both sides.

9x+15−15<−12−15

9x<−27

Step 2: Divide both sides by 9.

9x

Answer:

$35.75

Step-by-step explanation:

.35 • 55

19.25

This is the amount off.

55-19.25

35.75

Answer:

19.25

Step-by-step explanation:

you set up a proportion x/55=35/100

you cross multiply the divide by the 100

then you subtract 19.25 from 55 which = 35.75

Answer:

A

Step-by-step explanation:

1.9 about 2, and 4.4 is about 4.

2x4=8

So it is safe to say between 4 and 10.

Answer:

Your answer is A, or -200.

Since your slope is going down, you know that the number is going to be a negative value. Then, check where the line hits a direct point. You would notice that it hits every 200 number values, which means that your answer is A.

Answer: A

Answer:

[tex]3 > b[/tex]

Step-by-step explanation:

Given

[tex]a = 1[/tex]

[tex]c = 2[/tex]

Required

Inequality to measure the length of b

The triangle inequality theorem states that:

[tex]a + b > c[/tex]

[tex]a + c > b[/tex]

[tex]b + c > a[/tex]

On side b, we make use of:

[tex]a + c > b[/tex]

Substitute values for a ad c

[tex]1 + 2 > b[/tex]

[tex]3 > b[/tex]

The inequality is: [tex]3 > b[/tex]

Answer:

Look below

Step-by-step explanation:

So you know a point and the slope, now you can substitute the values of the point for the equation.

Answer: y = (5/2)x + 7

Step-by-step explanation:

Plug in given numbers into the following equation:

y = mx + b

Solve for b:

-3 = (5/2)(-2) + b

-3 = -10 + b

b = 7

Answer:

[tex]f(x) = \frac{24}{25} * \frac{5}{6}^x[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (2,\frac{2}{3})[/tex]

[tex](x_2,y_2) = (3,\frac{5}{9})[/tex]

Required

Write the equation of the function [tex]f(x) = ab^x[/tex]

Express the function as:

[tex]y = ab^x[/tex]

In: [tex](x_1,y_1) = (2,\frac{2}{3})[/tex]

[tex]y = ab^x[/tex]

[tex]\frac{2}{3} = a * b^2[/tex] --- (1)

In [tex](x_2,y_2) = (3,\frac{5}{9})[/tex]

[tex]y = ab^x[/tex]

[tex]\frac{5}{9} = a * b^3[/tex] --- (2)

Divide (2) by (1)

[tex]\frac{5}{9}/\frac{2}{3} = \frac{a*b^3}{a*b^2}[/tex]

[tex]\frac{5}{9}/\frac{2}{3} = b[/tex]

[tex]\frac{5}{9}*\frac{3}{2} = b[/tex]

[tex]\frac{5}{3}*\frac{1}{2} = b[/tex]

[tex]\frac{5}{6} = b[/tex]

[tex]b = \frac{5}{6}[/tex]

Substitute 5/6 for b in (1)

[tex]\frac{2}{3} = a * b^2[/tex]

[tex]\frac{2}{3} = a * \frac{5}{6}^2[/tex]

[tex]\frac{2}{3} = a * \frac{25}{36}[/tex]

[tex]a = \frac{2}{3} * \frac{36}{25}[/tex]

[tex]a = \frac{2}{1} * \frac{12}{25}[/tex]

[tex]a = \frac{24}{25}[/tex]

The function: [tex]f(x) = ab^x[/tex]

[tex]f(x) = \frac{24}{25} * \frac{5}{6}^x[/tex]
