Answer:

250x + 525y ≤ 7800

no, 15 refrigerators and 8 pianos will not fit on the truck

Step-by-step explanation:

we know that x is the refrigerators and each one is 250 lbs

this can be written as 250x

we know that y is the pianos and each one is 525 lbs

this can be written as 525y

we also know that "no more than" is the same that as less than equal to

so this can be written as ≤

we can also say that the refrigerators and pianos has to be ≤ 7800

so now we have: 250x + 525y ≤ 7800

plug in 15 to x and 8 to y

250(15) + 525(8) ≤ 7800

3750 + 4200 ≤ 7800

7950 ≤ 7800

this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck

Answer:

#1: $36.94

#2: 4.9 continuous

#3?

#4 $18

#5 64in squared

Step-by-step explanation:

#1 2x9.95+19.9

$19.90+$14.95=34.85

6% of 34.85=2.09

$34.85+$2.09=

$36.94

#4 8 yards = 24 feet

432/24=

18

#5 4x2=8

8x8=64

remember to make sure it is squared because it is area

Answer:

B, C, F

Step-by-step explanation:

B- has different lengths for each side and different angles

C-has different lengths for each side and different angles

F-has different lengths for each side and different angles

Non congruent triangles means if shape is reflected or rotated they would not look the same. Congruent triangles have same equal length and angles are equal in measure.

Answer:

They are similar by SSS similarity. TUV ~ QRS

Step-by-step explanation:

yes

Answer:

ΔTUV ~ ΔQRS

Step-by-step explanation:

The sides on the smaller triangle are 15, 25, and 30.

The sides of the larger triangle are 42, 70, and 84.

15*X = 42

X = 2.8

25 * 2.8 = 70

30 * 2.8 = 84

Since all sides of the larger triangle are 2.8 times the sides of the smaller triangle, the two triangles are similar.

Answer: I am assuming its telling me to see where it is placed at so it would be (5,7).

I not for sure but I am pretty sure!

Good Luck!

Answer:

Measure of angle E is 37 degrees because the triangles are similar and angle c and angle e are the ones that match up.

Answer:

43%

Step-by-step explanation:

There are 39 girls. 21 of them like biology. 11 out of 34 who like chemistry are girls.

No. of girls who prefer biology = 21

There are (100-39) boys. 16 of them like physics. (34-11) of them like chemistry.

No. of boys who prefer biology = 100-39-16-34+11

                                                    = 22

Percentage of students who prefer biology = [tex]\frac{21+22}{100}[/tex] × 100%

                                                                        = [tex]\frac{43}{100}[/tex] × 100%

                                                                        = 43%

Answer:

because 116 - 180 = 64 +57 =121 -180 =59 I hope this helps!

Answer:

x=7,  angle a= 45 degrees, angle b= 65 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65

Answer:

x = 7

m∠B = 65

m∠A = 45

Step-by-step explanation:

So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.

180 - 70 = 110

Now we can set both equations equal to 110.

2 + 9x + 7x - 4 = 110

Now simplify.

2 + 9x + 7x - 4 = 110

2 + 16x - 4 = 110

16x - 2 = 110

      +2       +2

------------------

16x = 112

÷16       ÷16

-----------------

x = 7

So now you can just plug 7 in for x to check your answers

2 + 9(7) = 65

7(7) - 4 = 45

65 + 45 + 70 = 180

Answer:

Anniversary sale price= $570

Step-by-step explanation:

Giving the following information:

Purchase cost= $400

Mar-up percentage= 90%

First, we need to calculate the "normal" selling price:

Selling price= 400*1.9= $760

Now, we can determine the anniversary sale price:

Anniversary sale price= 760 - (760*0.25)= $570

Answer:

-430

Answer:

(2 , 0)

I solved this using the comparison method ;)

Answer:

y=4×+6=56

56×65

45×34=

2×-4=67

Lets denote the numbers x and y:

The sum of two numbers 94 → x + y = 94

Their difference is 12 → x - y = 12

We have:

x + y = 94

x - y = 12

----------------  Add both equations

2x = 106

x = 106/2

x = 53

Using first equation:

x + y = 94

53 + y = 94

y = 94 - 53

y = 41

A/ The numbers are 53 and 41.
