30 + a = 40
40 + b = 30
c - 3 = 8
d - 3 = 8
plz answer.

Answer:

It would take 6 hours.

An equation for that could be: 50x = 300 (X is how long it would take)

So 50 mph• X (time spent) = 300 miles

You didn't give me any scatterplots to look at so I can't help you with that sorry

Answer:

Train A is 497 tons and Train B is 13 tons

Step-by-step explanation:

Let a represent the weight of Train A, and b represent the weight of Train B

Set up a system of equations:

a + b = 510

a - b = 484

Solve by elimination by multiplying the top equation by -1

-a - b = -510

a - b = 484

Add these together, and solve for b:

-2b = -26

b = 13

Find the weight of Train A by plugging in 13 as b into one of the equations, and solving for a

a + b = 510

a + 13 = 510

a = 497

So, Train A is 497 tons and Train B is 13 tons

Answer:

7/10

Step-by-step explanation:

To make things simple, let's turn 80% into a fraction, 8/10. To get a common denominator let's turn 8/10 into 4/5. Since they are both of equal size, the first group would have 2/5 left-handed people and the second 1/5 left-handed people. Let's imagine that each group has 5 people in it. There would be 10 people in total. There is 1 person for each fifth so we can add now. 4 + 3 = 7 right handed people. To check, 2 + 1 = 3 and 3 + 7 = 10. so 7/10 of the class is right-handed.

Volume of cylinder = 1,156.57 cm³

Step-by-step explanation:

Given:

Radius R = 4 cm

Height of cylinder = 23 cm

Find:

Volume of cylinder

Computation:

Volume of cylinder = πr²h

Volume of cylinder = (22/7)(4)²(23)

Volume of cylinder = (22/7)(16)(23)

Volume of cylinder = 1,156.57 cm³

Answer:

40 Square Units

Step-by-step explanation:

Easy way to find area: Diagonal 1 * Diagonal 2 divide by 2 = your answer

Diagonal 1 (AC) = 5 + 5 = 10

Diagonal 2 (BD) = 4 + 4 = 8

10 + 8 = 80, 80/2 = 40

Answer: 40 square units

Step-by-step explanation:

Given

diameter (d) = 36 inches

Radius (r) = d / 2 = 36 / 2 = 18 inches

Now

Area of the circle

= πr²

= 3.14 * 18²

= 1017.36 inches²

6/12+8/12+9/12=23/12=1 11/12

Answer:

D. 1 11/12

Step-by-step explanation:

Let's set up our common denominator first. To do this we need to find a number divisible by 2, 3, and 4.

Multiply 3 by 4 and you'll come out with 12. 12 is divisible by 2.

Now, multiply your fractions by the numbers they need to get the denominator to 12.

1/2 x 6/6 = 6/12

2/3 x 4/4 = 8/12

3/4 x 3/3 = 9/12

Add your numerators.

6 + 8 + 9 = 23.

Your fraction should look like 23/12.

Subtract 12 from 23 and you should get 11. Because 12 equals a whole, we can go ahead and put one.

1 and 11/12.

Answer:

180

straight

Step-by-step explanation:

Hello There

So we are given that angle a is equal to 11x + 37

we are also given that x = 13

because we are given the value of x we can simply find the measure of angle A by plugging in 13 to x into the expression

so basically angle A = 11 ( 13 ) + 37

11 * 13 = 143

143 + 37 = 180

now we want to classify the angle

here are the angle types and what they measure

(let x be measure of angle)

acute 0 < x < 90

so an acute angle has a measure of less than 90 degrees

the measure of angle A is 180 degrees so we can clarify that it is not an acute angle

right angle x = 90

a right angle has a measure of 90 degrees

angle a has a measure of 180 degrees therefore it is not a right angle

obtuse angle 90 < x < 180

the measure of an obtuse angle must be less than 180

because angle a = 180 it is not classified as an obtuse angle

straight angle x = 180

the measure of a straight angle is 180 degrees

angle a measure 180 degrees so we can conclude that angle a is a straight angle

neither positive nor negative

Step-by-step explanation:

In order to identify a type of correlation the points have to form where we can draw a line through the points and most of the points will be near that line drawn.

Because most of the points graphed are scattered we cannot identify if it has a positive or negative correlation

Answer:

1.92

Step-by-step explanation:

Given :

Cups of flour = 13

Cups of cinnamon = 25

Number of cinnamon cups needed for each cup of flour :

Number of cinnamon cups / number of cups of flour

25 / 13

= 1.923

Hence, about 1.92 cups of cinnamon is needed per cup of flour

I can confirm that it is A as I took the test and got 100%.

The length of side A in the new parallelogram will be [tex]2[/tex] cm.

Scale Factor is defined as the ratio of size of new image formed to the size of old image.

We have,

A parallelogram with side lengths [tex]18[/tex] centimeters and [tex]45[/tex] centimeters.

And,

A second parallelogram with side lengths [tex]A[/tex] and [tex]5[/tex] centimeters.

Now,

Scale Factor [tex]=\frac{size\ of\ new\ image}{size\ of\ old\ image}[/tex]

So,

Now, Comparing sides ,

We get,

Scale Factor [tex]=\frac{45}{5}=9[/tex]

i.e. the second parallelogram have Scale Factor of [tex]9[/tex].

So,

Other sides of both parallelograms will be of same Scale Factor.

i.e.

[tex]=\frac{18}{A} =9[/tex]

⇒

[tex]A=2[/tex] cm

Hence, we can say that the length of side A in the new parallelogram will be [tex]2[/tex] cm.
