Evaluate the expression if r = 12 and t = -6.<br> (t-r)/3
Lynna [10]

Answer:

-6

Step-by-step explanation:

\frac{(t-r)}{3}

input the numbers

\frac{(-6-12)}{3}

do the problem in the parentheses first

-6-12 = -18

now it becomes

-\frac{18}{3}

simplify and you'll get

-6

this is because -18 ÷ 3 =

-6

I NEED HELP ASAP
SVEN [57.7K]

Alright, lets get started.

If the polygon measures 45 degree exterior angle and we are asked to find number of sides, there is a formula for that.

\frac{360}{n} = value of exterior angle

Where n is number of sides of ploygon

\frac{360}{n}  = 45

Multiplying n into both sides

\frac{360}{n} * n = 45 n

360 = 45 n

Now divide 45 in both sides

\frac{360}{45}  = \frac{45n}{n}  = n = 8

n = 8

Means number of sides of polygon is 8, hence its Octagon. Answer

Now we have given 45 exterior angle hence interior angle would be

180 - 45 = 135°

So, sum of all interior angles would be = number of sides * interior angle

sum of all interior angles would be = 8 * 135 = 1080

Hence sum of all interior angles would be 1080°. Answer

Hope it will help :)

To find the surface area of the pyramid, in square inches, Vikram wrote (33.2) (34.2) + 4 (one-half (34.2) (28.4)). What error d
madam [21]

Answer:

B. He used the wrong expression to represent the area of the base of the pyramid.

Step-by-step explanation:

Given

See attachment for pyramid

Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4

Required

Vikram's error

The surface area of a square pyramid is:

Area = Base\ Area + 4 * Area \triangle

Where

Base\ Area = Length * Length

Base\ Area = 34.2 * 34.2

4 * Area \triangle = 4 * \frac{1}{2} * Base * Height

4 * Area \triangle = 4 * \frac{1}{2} * 34.2 * 28.4

So:

Area = Base\ Area + 4 * Area \triangle

Area = 34.2 * 34.2 + 4 * \frac{1}{2} * 34.2 * 28.4

By comparing the calculated expression with

Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4

Option (b) is correct

Please help me solve the table below
ArbitrLikvidat [17]

Answer:

2, 4 ,6 8

Step-by-step explanation:

Given condition y = 2x

When x = 1 , y = 2 *1 = 2

When x = 2 , y = 2 * 2= 4

when x = 3 , y = 2* 3 = 6

When x = 4 , y = 2 * 4 = 8

Hope it will help :)
