Answer:

Increase: 1.7

Decrease: 0.3

Step-by-step explanation:

Increase:

100% + 70% = 117%

117/ 100 = 1.7 (multiplier)

Decrease:

100% - 70%= 30%

30/ 100 = 0.3 (multiplier)

Choose the graph which represents the solution to the inequality:<br> 3x + 8 ≥ 11
Mashutka [201]

The solution of the inequality is x ≥ 1.

Solution:

Given inequality:

3 x+8 \geq 11

To find the solution of the inequality:

3 x+8 \geq 11

Subtract 8 from both sides.

3 x+8-8 \geq 11-8

3 x \geq 3

Divide by 3 on both sides.

$\frac{3 x}{3} \geq \frac{3}{3}

On simplifying this, we get

x \geq 1

The solution of the inequality is x ≥ 1.

The graph of the solution is attached below.

Joshua has a bag of marbles. In the bag are 5 white marbles, 3 blue marbles, and 7 green marbles. Peter randomly draws one marbl
Step2247 [10]

Answer:

1 / 5

Step-by-step explanation:

Given that:

Number of white marbles = 5

Number of blue marbles = 3

Number of green marbles = 7

Required is the approximate probability of drawing 2 green marbles, Note that drawing is done without replacement :

Probability = required outcome / Total possible outcomes

Total possible outcomes = sum of all marbles = (5 + 3 + 7) = 15 marbles

First draw:

P(Green) = 7 / 15

Second draw:

Required outcome = 7 - 1 = 6

Possible outcomes = 15 - 1 = 14

P(green) = 6 / 14

Probability of drawing out two green marbles :

(7/15 * 6/14) = 42 / 210 = 1 / 5

On a piece of paper, use a protractor to construct a triangle with angle measures of 40 degrees and 60 degrees.
Andru [333]

Answer:

80

Step-by-step explanation

Well every triangle has to equal 180 degrees.

So you would add the two degrees you already have, which on this one you would get 100.

Then, you would subtract that number from 180 to get 80.


Hope this helps you!!
