(1 - 15%) × 80 =

(100% - 15%) × 80 =

85% × 80 =

85 ÷ 100 × 80 =

Answer:

33 and -39

Step-by-step explanation:

Angle on a straight line = 180

|5x + 15| = 180 and |5x + 15| = -180

5x + 15 = 180

Subtract 15 from both sides;

5x = 165

Divide both sides by 5;

x = 33

5x + 15 = -180

Subtract 15 from both sides;

5x = -195

Divide both sides by 5;

x = -39

joseph is planting a garden. he plants 2 tomato plants for every 5 peppers. If joseph plants 14 tomato plants how many pepper plants does he plant?

Answers

Answer:

Ratio of tomato plant to that of pepper plant = 2:5

Let x be the number of pepper plants for 14 tomato plants.

Now, according to the question,

2:5 = 14:x

14×5 = 2x

x = 70/2 = 35 plants.

Step-by-step explanation:

So he/she would have 35 pepper plants to plant

A 12-foot ladder is placed 4 feet away from a house as shown.

A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees.

What is the value of x, rounded to the nearest degree?

x ≈
°

According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.

Is this ladder being used safely?

Answers

Answer:

Answer: x = 71 degrees. Yes, the ladder meets safety standards

Discussion:

The problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x". For this triangle,

cosx = (side adjacent to angle) / hypotenuse

= 4 / 12

= 1/3

To find "x" take the inverse cosine of each side to find that :

x is approximately 70.52 degrees. That's 71 degrees rounded to the nearest degree.

Step-by-step explanation:

select the correct solution for 6x = 30
(A) x = 24
(B) x = 1/5
(C) x = 5
(D) x = 36

Answers

Answer:

answer is (C) x = 5

I hope it helps you

:-))

There are two ways to solve this u can divide the 30 by 6 (30/6=5) or you can ask yourself what numbers times 6 is equal to 30? 6 time ? =30 which is also equal to 5.
So that would make (c) x=5 the correct answer

Square ABCD has diagonals AC¯¯¯¯¯

and BD¯¯¯¯¯

. What is m∠ABD

A

180º

B

90º

C

45º

D

360º

Answers

Answer:

option (c)

Step-by-step explanation:

Given,

ABCD is a square.

AC and BD are diagonals

We know that,

Sides of the square make 90 degrees with each other.

And Diagonals bisect the opposite angles of the square.

Now,

[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]

[tex]\angle ABC = 90^\circ[/tex]

[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]

[tex]\angle ABD = \dfrac{90^\circ}{2}[/tex]

[tex]\angle ABD = 45^\circ[/tex]

Hence, option (c) is correct.

Use the Distributive Property to solve the equation. -2(x + 4) = 8 Apply the Distributive Property and simplify. - 2x+ what = 8

Answers

Answer:

if your asking for the -2(x+4)=8 equation its -8

Hey there!

First, use the Distributive Property and distribute -2:

-2(x+4)=8

-2x-8=8

Add 8 to both sides:

-2x=8+8

-2x=16

Divide both sides by -2:

x=-8

Hope everything is clear.

Answer:

Through pythogoras theorem

a^2+b^2=c^2

20^2+16^2=c^2

c^2=400+256

c^2= 656

c= square root of 656

c=25.6 inches or 30 inches

Missing side 25.6 inches or 30 inches

c^2 = a^2 + b^2

c^2 = 16^2 + 20^2

c^2 = 256 + 400

c^2 = 656

Now, square root both sides to find the missing length of c or the hypontenuse.

Answer: c = 25.6 inches
