Find the Surface Area of the Pyramid. Round to the NEAREST TENTH.

Answers

Answer:

465.75 or 465.8 rounded to the nearest tenth

Step-by-step explanation:

You would multiply 16.2 and 14.5 and divide by 2 to get 117.45. You then multiply by 3 for the 3 sides to get 352.35. Lastly, to find the area of the base you would need to multiply 16.2 and 14 and divide it by two to get 113.4. Add it with the 3 sides and you get 465.75.

find the value of x when y equals -7.
2(3x - 7) = 9y​

Answers

Hey there!


2(3x - 7) = 9y

2(3x - 7) = 9(-7)

2(3x - 7) = -63

2(3x) + 2(-7) = -63

6x - 14 = -63

ADD 14 to BOTH SIDES

6x - 14 + 13 = -63 + 13

SIMPLIFY IT!
6x = -63 + 13

6x = -49

DIVISION 6 to BOTH SIDES

6x/6 = -49/6

SIMPLIFY!
x = -49/6

x = -8 1/6


Therefore, the answer should be:

x = -8 1/6 (or x = -49/6 [EITHER OF THOSE SHOULD BE YOUR RESULT BECAUSE THEY ARE BOTH EQUAL TO EACH OTHER])

Find the measure of angle x in the figure below:

A) 35
B) 47
C) 51
D) 62

Answers

Answer:

The value of y = 62°

and x = 50°

Step-by-step explanation:

=> 57° + y + 61° = 180°

=> 118° + y = 180°

=> y = 180° - 118

=> y = 62°

Now ,

x° + y° + 67° = 180° { sum of angles of a triangle is 180° }

=> x° + 62° + 68° = 180°

=> x + 130° = 180°

=> x = 180° - 130°

=> x = 50°

5 pails
6 pails
4 pails
3 pails

Answers

Answer:

3 pails

Step-by-step explanation:

The square room's base is 14 x 14 = 196

You need to fill the whole room so you might get extra

so... 196 / 90 = 2.177777778

which means you will need  3 and you will have extra

Answer:

3 pails!

Step-by-step explanation:

The area of the ceiling:

A = 14² = 196 ft²

We need plaster to cover 196 ft².

196 : 90 = 2.17778

Answer:

25

Step-by-step explanation:

Let the whole number be W

W x 140% = 35

Percentage to Decimal conversion

Divide % by 100 to get the decimal140/100 = 1.4

Solving

1.4W = 35W = 35/1.4W = 175/7W = 25

Answer:

25

Step-by-step explanation:

We're given:

140% of a number is 35

Let the number be x.

First, convert 140% into a decimal:

1.4

Then, write an equation:

1.4x = 35

x = 35 ÷ 1.4

x = 25

Therefore, 140% of 25 is 35.

A bowl has 3 red beads and 7 blue beads. Two beads are selected at random one at a time. First a red bead is drawn and placed on a table. Next a blue bead is drawn.

What is the probability of this event?

Drag and drop the answers into the boxes to complete the sentences.

Answers

The probability that first a red bead is drawn and next a blue bead is drawn is 7/30,and both events are dependent

How to determine the probability?

The distribution of the beads are:

Red = 3

Blue = 7

Total = 10

The probability of selecting the red bead first is:

P(Red) = 3/10

When the red bead is selected, the number of beads becomes 9

So, the probability of selecting a blue bead is

P(Blue) = 7/9

The probability of the event is then calculated using:

P = 3/10 * 7/9

Evaluate

P = 7/30

Hence, the probability of the event is 7/30
