Answer:

C and D are rhombuses

Step-by-step explanation:

C is a rhombus because the shape is a parallelogram with all equal sides. And if the sides are all equal in a parallelogram then it is a rhombus.

D is also a rhombus because the shape is a square with equal sides and with right angles. Furthermore, a square is always a rhombus because of the sides and the right angle.

So the final answer is C and D.

Hope it helped!

At a school number of boys : number of girls = 11 : 9

aliya0001 [1]

Ok, so 11:9
11-9 = 2
which means that 124= 2:1
124/2 = 62
so 62:0
now 11 x 62= 682
9 x 62= 558

so the ratio is 682:558
now 682 + 558 = 1,240
There are 1,240 total students in the school. 682 boys and 558 girls

Joe's Plumbing and Mark's Plumbing have different ways of charging their customers. The function defined by J(t)=45t represents

puteri [66]

Answer:

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

Step-by-step explanation:

Let

t ------> the number of hours

J(t) ---->the total amount in dollars that Joe's Plumbing charges

M(t) ---->the total amount in dollars that Mark's Plumbing charges

we know that

The linear equation in slope form is equal to

$f(x)=mx+b$

where

m is the slope or rate of the linear equation

b is the y-intercept (initial value)

In this problem we have

Joe's Plumbing

$J(t)=45t$

The slope or rate is equal to

$m=\$45\ per\ hour$

$b=\$0$

Mark's Plumbing

$M(t)=40t+25$

The slope or rate is equal to

$m=\$40\ per\ hour$

$b=\$25$

therefore

Joe's Plumbing charges more per hour ($45) than Mark's Plumbing (S40)

Solve the inequality r+7 is lesser than or equal to 12

zvonat [6]

R+7(<=)12

r+7 should result: 0,1,2,3,4,5,6,7,8,9,10,11,12

so, here's the process:

r+7= 0
r= 0-7
r= -7

r+7= 1
r= 1-7
r= -6

r+7= 2
r= 2-7
r= -5

r+7= 3
r= 3-7
r= -4

r+7= 4
r= 4-7
r= -3

r+7= 5
r= 5-7
r= -2

r+7= 6
r=6-7
r= -1

r+7= 7
r= 7-7
r= 0

r+7= 8
r= 8-7
r= 1

r+7= 9
r= 9-7
r= 2

r+7= 10
r= 10-7
r= 3

r+7= 11
r= 11-7
r= 4

r+7= 12
r= 12-7
r= 5

r = { -7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5}
