22. Two automobiles started at the same time from a point, but traveled in
opposite directions. Their rates were 45 and 65 miles per hour respectively.
After how many hours were they 440 miles apart?

Answer:

They did not state exactly what the width or length is. So in this case, let's name the number of width to be x. And thus we can derive to the conclusion of,

Step-by-step explanation:

Width : x

Length : x-44 (from the 1st sentence of question)

So, We all know that a rectangle has 2 Lengths and 2 widths. So we can derive the conclusion that,

2(x)+2(x-44)=150150

2x+2x-88=150150

4x-88= 150150

4x= 150150+88=150238

4x=150238

x= 150238÷4

=37559.5

Answer:

The width is 8 meters and the length is 3(8)-2=22 meters. Hope this helps (owo)/ brainlist please.

Step-by-step explanation:

Let x= the width

then 3x-2= length (because the length is 2 meters less than 3 times the width)

P=2l+2w

60=2(lenght)+2(width)

60=2(3x-2)+2x      

60=6x-4+2x    Distribute

60=8x-4          Combine like terms

64=8x             Divide both sides by 8

8=x

Answer:

Step-by-step explanation:

10+60t≤280

60t≤280-10

60t≤270

6t≤27

2t≤9

t≤9/2

t≤4.5

t=4 hours

first subtract $10 from$280 and you get $270

270 divided by 60 = 4.5

so the answer is four and a half hours

Answer:

16x^4

Step-by-step explanation:

first compute -2 to the 4th power, then x to the 4th power

(-2)^4= positive 16 because of parentheses and the exponent(4) is even

(x)^4 is just x^4

so multiply 16 and x^4 together and you get 16x^4

Answer:

Step-by-step explanation:

here you go mate'

step 2

(-2x)^4  put (-2x) in four places

(-2x)(-2x)(-2x)(-2x)

step 3

(-2x)(-2x)(-2x)(-2x)  multiply

answer

16x^4

The kind of ice cream the least number of students prefer is Strawberry ice cream.

Step-by-step explanation:

We convert all given values to decimal

Hiroshi found that:

a) For vanilla ice cream

3/5 of his class prefers vanilla ice cream

3/5 to decimal = 0.6

b) For Chocolate ice cream

26% prefers chocolate ice cream

26% to decimal = 0.26

c) For strawberry ice cream

0.14 prefers strawberry ice cream

0.14 = 0.14

Arranging the numbers in order from least to greatest, we have :

0.14, 0.26 , 0.6

The kind of ice cream the least number of students prefer is Strawberry ice cream.

Answer:

The Area of the sector is: A = 95.4 cm²

Step-by-step explanation:

Given

Central angle Ф = 135°

radius r = 9 cm

To determine

Area of the sector = ?

The Area of the sector can be calculated using the formula

A = Ф/360 × πr²

substitute Ф = 135°, r = 9 and π = 3.14

A = 135/360 × (3.14) (9)²

A = 95.4 cm²

Therefore, the Area of the sector is: A = 95.4 cm²

Answer:

Step-by-step explanation:

Because these two triangles are isoceles triangles, two angles are the same, which in this case would be 78. 78 times 2 would give us 156 for the right triangle, but since 180 - 156 does not equal 16, they are not similar nor congruent.

Step-by-step explanation:

multiplying the 2nd eqn by 9 we get,

9x+9y=81

then,subtracting 1st and 2nd eqn

9x+5y=41

9x+9y=81

- - -

__________

0. -4y=-40

we get y = 10

then we get x=9-y

x=9-10

x= -1

so x is -1 and y is 10
