Answer 1

Answer:

see below

Step-by-step explanation:

a. -11r ≥ 220

Divide both sides by -11 to isolate r.

r ≥ -20

b.

-8 ≤ -7 + (x/10)

Add 7 to both sides.

-1 ≤ x/10

Multiply both sides by 10 to cancel out the denominator of x.

-10 ≤ x

c. -1 - 6(5q - 2) ≥ -139

Distribute the -6 across the parentheses.

-1 - 30q + 12 ≥ -139

Combine like terms on the left side.

-30q + 11 ≥ -139

Subtract 11 from both sides.

-30q ≥ -150

Divide both sides by -30 to isolate q.

q ≥ 5

Hope this helps!

Answer 2
-11r>=220

divide both sides by -11
since both sides are divided, flip the sign

r<=-20
r is less than or equal to negative twenty

Pls answer dont sweat it though u tried ur best right (its worth branliest)

Answers

Answer:

A

Step-by-step explanation:

B is 180

C looks like 30-ish

D looks like 270

so A is the only one that looks to be 45

Answer:

C

Step-by-step explanation:

45/360 covers about 1/8 of the entire degress of a circle, this means the image that corresponse with be on the smaller side.

a- this seems closer to 1/4 and would not be the best match

b- this covers half, so this is much to large to correspond

c- this is the closest eyballing it, as it looks small enough to cover 1/8th as well as be properly notated

d- this is smaller and could be correct except the notation on it shows that it is going around the outside (so 360- that angle)

I hope this helps!

Answers

The answer is 62.8
Use the formula C=(3.14)d
C=(3.14)(20)
C= 62.8
Circumference of a circle = 2(3.14)r
The radius is 10
So 2 x 3.14 x 10 =62.83

What is the solution set for -4x-10 ≤ 2?

Answers

Answer:

x≥−3

Step-by-step explanation:

Let's solve your inequality step-by-step.

−4x−10≤2

Step 1: Add 10 to both sides.

−4x−10+10≤2+10

−4x≤12

Step 2: Divide both sides by -4.

−4x /−4 ≤ 12 /−4

= x≥−3

brainliest please?

Answer:

x ≥ -3

Step-by-step explanation:

you add 10 on both sides

-4x - 10 ≤ 2

      +10  +10

=   -4x ≤ 12

then you divide -4 on both sides to get the x by itself

12/-4 is -3

since you divided by a negative you flip the sign

8. Find the surface area of a triangular pyramid if the area of each phase is 16 cm² and each of its lateral faces has an area of 9 cm².

Answers

Answer:

The base of a right pyramid is an equilateral triangle with area 16√3 cm².  area of one of its lateral faces is 30 cm²

To find :   height (in cm) i

Solution:

The base of a right pyramid is an equilateral triangle with area 16√3 cm²

Area of an equilateral triangle = (√3 / 4) Side ²

(√3 / 4) Side ²  = 16√3

=> Side ²  = 64

=> Side = 8 cm

Distance of center of triangle to mid point of Side for Equilateral triangle = side/ 2√3     = 8/ 2√3  = 4/√3

Let say Height  = H

Slant Height =  √((4/√3)² + H²)

Area of lateral surface = (1/2) * base * Slat Height

= (1/2) * 8 * Slant height = 30

=> Slant height = 15/2

15/2   = √((4/√3)² + H²)

=> 225/4  =  16/3  + H²

=> 611/12  = H²

=> H = 7.135  cm

Please help me with this volume problem!♪☂♧(^.^):ω

Answers

Answer:

A. 4 * 3 * 7 and 1 * 3 * 4

D. 4 * 6 * 1 and 6 *4 * 3

Step-by-step explanation:

First I'll find the volume of the figure itself.

I'll split it into two figures. A 4 * 3 * 7 rectangular prism and a 1 * 3 * 4 rectangular prism. (That confirms A as one of the answers.)

(4 * 3 * 7) + (1 * 3 * 4)

(12 * 7) + 12

84 + 12

96 cubic meters

Now, I'll do the math to see which one of the remaining choices equals 96.

(4 * 6 * 7) + (3 * 3) = (24 * 7) + 9 = 168 * 9 = 177 cubic meters (X)

(4 * 7) + (4 * 3 * 6) = 28 + (12 * 6) = 28 + 72 = 100 cubic meters (X)

(4 * 6) + (4 * 6 * 3) = 24 + (24 * 3) = 24 = 72 = 96 cubic meters (✓)

(4 * 6 * 3) + (7 * 3 * 3) = (24 * 3) + (21 * 3) = 72 + 63 = 135 cubic meters (X)

With the problem solved, A & D are the answers to this question.

Your answer would be C
