Jose had a rectangular piece of paper that

was 80 mm long and 70 mm wide. He cut

the paper in half. What is the area of each

half of the paper in square millimeters?


A. 5600 sq mm

B. 2800 sq mm

C. 140 sq mm

D. Not here

Answers

Answer:

B. 2800 sq mm

Step-by-step explanation:

Given the following data;

Length = 80 mm

Width = 70 mm

Area of rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

Area of rectangle = 80 * 70

Area of rectangle = 5600 mm²

Since the paper (area of rectangle) was halved, we would divide by 2;

Area of each half = 5600/2

Area of each half = 2800 sq mm.

Step-by-step explanation:

first, you have to look pythagoras theorem (in picture)

then; x² + 14² = 20²

x² + 196 = 400

x² = 204

x = [tex]\sqrt{204}[/tex] = [tex]2\sqrt{51}[/tex]

x is less than 5.
Because the circle is not closed, there’s no equal to.
Because it’s going to the left, it’s less.

Answer:

A; x< 5

Step-by-step explanation:

A simple way to remember the difference between greater than or less than is picturing the symbol as an alligator, the mouth of the alligator, the open end, eats the bigger number. The line under the greater than/ less than symbol means "or equal to". An open circle on a number line means that it's NOT "or equal to", so the answer isn't B or D. On the number line, it shows what x could equal. The arrow falls on 0, I'll use 0 as an example. Is 0 less than 5? Yes. If x could equal 0, that means that x is less than 5.

Lucas wants to have at least $4,000 in his account. He has $2,500 to deposit into an account that earns simple interest at a rate of 6%. What is the fewest number of years it will take Lucas to reach his goal?

Answers

Answer:

6.25 years

Step-by-step explanation:

Simple interest = principal x time x interest rate

simple interest = $4,000 - $2,500 = $1,500

1500 = $4,000 x 0.06 x n

1500 = 240n

divide both sides by 240

n = 6.25 years

Answers

Answer:

-152 feet in relation to sea level.

Step-by-step explanation:

If it descends 20 feet per minute, you just multiply the distance by the minutes. So 20x7 and you will get 140. You can't forget that it's already -12 below sea level, so it's 12 feet deeper. It's -152 feet in relation to sea level.

Answers

Answer:

y = 4x - 9

Step-by-step explanation:

y = 4x + 2

the the slope m is 4

the new line which paraller to the first one will have a slope 4 too

M = 4

then, the new slope-intercept form which pass through (x1,y1), in this case (5,-4) is

y - y1 = M(x - x1)

y - (-4) = 4(x - 5)

y + 4 = 4x - 5

y = 4x - 5 - 4

y = 4x - 9

Answer:

Step-by-step explanation:

FYI only

Slopes of parallel lines are the same and y-intercepts are different

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

y - [tex]y_{1}[/tex] = 4( x - [tex]x_{1}[/tex] )

A train travels 423 miles every 9 hours. What is the unit rate of the train?

Answers

Answer:

47 mph.

Step-by-step explanation:

The unit rate would be in mph.

Divide 423 miles with 9 hours:

423/9 = 47

47 mph, or miles per hour, is your answer.

~

Given that: Train travels 432 miles in every 4 hours

To Find: Unit rate of the train

⠀⠀⠀⠀⠀⠀__________________

Solution:-

we can find the unit rate of train by divide the distance and time.

⠀⠀

[tex]:\implies\sf{speed(v)} \: = \dfrac{distance(s)}{time(t)} [/tex]

[tex]:\implies\sf Speed\; (v) = \dfrac{423}{9}[/tex]

[tex]:\implies\sf Speed \: (v) = 47 \;mph\;(miles\;per\;hour)[/tex]

⠀⠀⠀⠀

[tex]\therefore \underline {\sf{Hence \: , \: \pmb{47mph} \: is \: the \: required \: answer}}[/tex]

(-3 + 4) x 66 + -19 x 8 - 2

Answers

Answer:

-88

Step-by-step explanation:

(-3 + 4) x 66 + -19 x 8 - 2

According to PEMDAS (or GEMDAS), you start with the parenthesis. So you do the equation in the parenthesis.

-3+4= 1

Now you replace it with your answer.

1 x 66 + -19 x 8 - 2

You next do multiplication.

1*66=66

66+ -19 x 8 -2

Multiplication again

-19*8=-152

66 + -152 - 2

Now there is only addition and subtraction left so you solve left to right.

66 + -152= -86

-86-2=-88

The answer is -88

If 1 inch = 9 feet, and the model is 7.5 inches,

you just need to do 7.5 • 9 = 67.5 feet.

OR

7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5

63 + 4.5 = 67.5
