Answer:  17.28 cm^2

Step-by-step explanation:

You can also use AC as the base, then BE will be the height to that.

Assuming you want your answer in cm^2, then (7.2*4.8)/2 = 17.28 cm^2.

Answer:

2160mm

Step-by-step explanation:

Recall that to find the area of a triangle, you need to follow the formula:

A = 1/2 * b * h

But first we need to convert the cm to mm, or else our calculations will be incorrect:

9.6 cm = 96 mm

4.8 cm = 48 mm

Let's cut the triangle into two pieces to make it easier for us to find the area. We'll start with triangle ACD:

A = 1/2 * 36 * 72

A = 1/2 * 2592

A = 1296 mm

Now that we have the area for triangle ACD, let's move on to try to find the area of triangle DCB:

A = 1/2 * 36 * 48

A = 1/2 * 1728

A = 864

It's time to add them up:

(DCB) 864 + (ACD) 1296 = 2160

The area of the triangle is 2160 mm.

Answer:

  B. 2 in

Step-by-step explanation:

The lengths are proportional, so you have ...

  blueprint length / room length = (1/5 in)/(3 ft) = (x in)/(30 ft)

Multiplying by 30 ft gives ...

  x in = (1/5 in)(30/3) = 10/5 in = 2 in . . . . . note that units of ft cancel

The blueprint length of the room is 2 inches.

Comment on "convert the fraction"

As a general rule, you can work math problems with the numbers in any convenient form: fractions, decimals, scientific notation, percentages. Your calculator or your mental arithmetic methods may prefer one form over another, but conversion isn't always necessary.

Answer:

7.6

Step-by-step explanation:

From the graph, we know the lengths of two legs.

  a = 3

  b = 7

Knowing this, we can use the Pythagorean Theorem to solve for c, the hypotenuse. (remember,  a^2 + b^2 = c^2)

c = √a2 + √b2  

= √(7)2 + √(3)2

= √49 + √9

= √58

= 7.6

Answer:

-6 < n < -4

Step-by-step explanation:

Solving the inequality 5 + 7n > -37  :

5 + 7n > -37

⇔ 7n > -37 - 5

⇔ 7n > -42

⇔ n > -42/7

⇔ n > -6

Solving the inequality n + 8 < 4 :

n + 8 < 4

⇔ n < 4 - 8

⇔ n < -4

Then , the solution to the compound inequality

5 + 7n > -37 and n + 8 < 4 is :

All real numbers n ,where -6 < n < -4

The solution in interval notation (-6 , -4)

Answer:

Base of figure A = 12 units

Step-by-step explanation:

Given:

Base of figure B = 15 units

Ratio of figure A to figure B = 4:5

Find:

Value of X

Computation:

X / 15 = 4 / 5

x = 4(15) / 5

x = 12

Base of figure A = 12 units

Answer:

{-5,15}

Step-by-step explanation:

because this function is constantly decreasing, we can get our range by looking at the endpoints:

f(-5) = 15

f(5) = -5

Answer:

x = 4

Step-by-step explanation:

10 = -1/4 x + 11

10 - 11 = -1/4 x

-1 = - 1/4 x

x = 4

Answer:

3

Step-by-step explanation:

You might just think that I subtracted but on the triangle the last side is the base which is always smaller.

Answer: The answers are 4, 8, 10

To solve, you must use the Triangle Inequality Rule -

Subtract 7-4=3; therefore, the 3rd side must be greater than 3

Add 7+4=11; therefore, the 3rd side must also be less than 11

Any number greater than 3 or less than 11 would be correct.

Answer:

$300

Step-by-step explanation:

First, you subtract 475 and 175.

Which equals 300. That means that you saved $300.

Answer:$300

Step-by-step explanation:

475 (base price) - 175 (sale price)

=300 (saved price)

Step-by-step explanation:

Answer:

x=7,  angle a= 45 degrees, angle b= 65 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65

Answer:

x = 7

m∠B = 65

m∠A = 45

Step-by-step explanation:

So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.

180 - 70 = 110

Now we can set both equations equal to 110.

2 + 9x + 7x - 4 = 110

Now simplify.

2 + 9x + 7x - 4 = 110

2 + 16x - 4 = 110

16x - 2 = 110

      +2       +2

------------------

16x = 112

÷16       ÷16

-----------------

x = 7

So now you can just plug 7 in for x to check your answers

2 + 9(7) = 65

7(7) - 4 = 45

65 + 45 + 70 = 180

Answer:

c = 0.6d + 1.2

Answer:

1. The slope of line l1 is -1/2

2. The slope of l2 is 2

Step-by-step explanation:

Perpendicular lines have opposite inverse slopes. The inverse of 2 is 1/2 and the opposite is -2. Therefore the opposite inverse slope of the perpendicular line, l1, is -1/2

When two lines are parallel, the slopes are the same. l2 is parallel to l therefore, they share the same slope.

Answer:

-a + 40 = 28, a = 12

Step-by-step explanation:

If he takes the opposite of his age, that means the current number is negative. We can get -a + 40 = 28, we can then simplify by subtracting both sides by 40 and getting -a = -12 which is equal to a = 12
