-7.5k is less than or equal to -82.5

Answers

Answer 1

Answer:

Answer:

$k\leq 11$

Step-by-step explanation:

I do not have a physical graph with me, so I'll only be able to solve the inequality.

If $$-7.5k \geq -82.5$,$ we can solve this inequality for $k$ as follows:

Divide both sides of the inequality by $-7.5$ :

$k \leq (-82.5)/(-7.5)$

Simplifying the right side:

$k \leq 11$

So, the solution to the inequality $-7.5k \geq -82.5\) = \(k \leq 11$ .

I have a triangle with side lengths of 2 cm, 3 cm, and 4 cm. If I have a second triangle that is similar that has a shortest side length of 4 cm, what is the longest side length?

Answers

so 2,3,4
another one is
4,x,y
the shortest is 2 and 4
4/2=2

2 time 2=4

the other triangle sides area obviously twice as large

2 times 2=4
2 times 3=6
2 times 4=8

the longest sides is 8 cm

A puppy will grow 28 in it is currently 1 foot tall

Answers

♥ If he will grow to 28inches and he is currently 1ft tall, then he needs to grow 16 more inches to get his full height.
♥ I did this by solving what was in 1ft (12 inch) so 28-12=16.
♥ Therefore he needs to grow 16 more inches.
♥Hope this helps♥

so 1+28in so 3ft4in would be correct idk just using the metric system

Find the supplement of the given angle. Then draw the two angles as linear pairs. Label each angle with its measure.m angle ABC=72 B will be the vertex

Answers

The supplement angle of angle ABC is 108 degrees because, supplement angles mean angles that add up each other to 180 degrees so 180-72=108

Garrett is a member of a movie club. He pays a monthly service fee of $5.75 and $2.50 for each movie he rents. Which expression represents how much money he will spend for renting x amount of movies a month?

3.25x

5.75x + 2.50

2.50x + 5.75

9.25x

Answers

ANSWER: 2.50x + 5.75

REASON: x represents the number of movies and if each movie is 2.50, then 2.50x will tell u what u paid for the movies, but u cant forget the monthly service fee of 5.75. So lets say u rent 5 movies, 2.50(5) + 5.75 = 12.50 + 5.75 = 18.25, so u would have spend 18.75 for the month

Answer:

$\$2.50x+\$5.75$
