Answer:

x = number of wheelbarrow = 40

y = number of wagon = 30

Step-by-step explanation:

Let

x = number of wheelbarrow

y = number of wagon

x + y = 70 (1)

x + 4y = 160 (2)

subtract (1) from (2) to eliminate variable x

4y - y = 160 - 70

3y = 90

y = 90/3

y =30

Substitute y = 30 into (1)

x + y = 70 (1)

x + 30 = 70

x = 70 - 30

x = 40

x = number of wheelbarrow = 40

y = number of wagon = 30

Answer:

A, B, D

Step-by-step explanation:

Answer:

A, B, D, E

Step-by-step explanation:

1. 100 = 100%, so seeing that there are 55 boys and 45 girls, we can go ahead and turn those into percentages, making this answer correct.

2. Once again, 100 = 100%, so 17 = 17%

3. "10/55 of those" isn't implying this is the boys only, but rather everyone, so this statement is not correct.

4. 10/35 of the students who chose math are girls. We can see that on the graph.

5. 8 + 8 = 16. Those are both the same number and half and half of the boys and girls...

If we know the quadratic formula, the quadratic formula is

x = [-b ± √(b²- 4ac)] / 2a

Gosh! So overwhelming! But let's look at the composition of a quadratic equation:

ax² + bx + c = 0

And we have 6x² - 3x = 1. So, what do we do? We need to put this quadratic equation into an easy form to find the value of a, b, and c to plug in to the equation.

We can just minus one on both sides to get this:

6x² - 3x - 1 = 0

Is it in the form of ax² + bx + c? Yes! a = 6, b = -3, and c = -1. Now, all we have to do is plug it into the quadratic formula.

x = [-b ± √(b²- 4ac)] / 2a

x = [-(-3) ± √((-3)²- 4(6)(-1))] / 2(6)

     [3 ± √(9- 4(6)(-1))] / 12

     [3 ± √(9 + 24)] / 12

     [3 ± √(33)] / 12

At this point, we should just use a calculator, and recognize we have two answers because of the plus-or-minus sign! (or this sign: ±)

[3 ± √(33)] / 12

1) [3 + √(33)] / 12 = 0.73 approximately

2) [3 - √(33)] / 12 = -0.23 approximately

So, x=0.73 and x= -0.23.

[tex]C' = (2,0)[/tex]

Step-by-step explanation:

Given [Missing from the question]

[tex]A = (-2,2)[/tex]

[tex]B= (1,3)[/tex]

[tex]C= (1,0)[/tex]

[tex]k = 2[/tex] --- scale factor

The new coordinates

The new coordinate is calculated by:

[tex]New = Old * k[/tex]

So, we have:

[tex]A' = A * 2[/tex]

[tex]A' = (-2,2) * 2[/tex]

[tex]A' = (-4,4)[/tex]

[tex]B' = B * 2[/tex]

[tex]B' = (1,3) * 2[/tex]

[tex]B' = (2,6)[/tex]

[tex]C' = C * 2[/tex]

[tex]C' = (1,0) * 2[/tex]

[tex]C' = (2,0)[/tex]

Answer:

Angle = A

A7 = A4 (Alternate interior angles)

A14 = A11 (Vertically opposite angles)

A11 = A6(Corresponding angles)

A4 = A14 (Given)

From this, we can get A6 = A4

A6 and A4 are alternate angles and are equal. So c and d are parallel.

A7 + A10 = 180 (Linear pair of angles) - ( 1 )

A13 = A10(Alternate interior angles)

Putting A13 in place of A10 in ( 1 ),

A7 + A13 = 180

Hence proved

Answer: 36

Step-by-step explanation:

3x6x2 I think..

What I would do is draw it out in a net. Then find the area of each area of the net. After you calculate the areas, you'll get these numbers: 18, 18, 12, 12, 6, and 6. Then add them all together.

The final answer is 72 square centimeters.

Answer:

C. Points F, J, and H are collinear.

Step-by-step explanation:

Given

See attachment for triangle

Required

Which statement is false

Options A, B and D are true while C is false.

Two points are said to collinear if a straight line can pass through them.

From the attached triangle, we can see that a straight line cannot pass through F, J and H.

Hence, they are not collinear.

Since the statement is false, then it cannot be used as part of the proof.

Answer:

88%

Step-by-step explanation:

First we multiply the mean by 5.

77.4 x 5 = 387

Then we add all of the test scores.

88 + 77 + 70 + 72 = 299

We subtract the total of the scores from 387, which we got from mulitplying the mean by 5.

387 - 299 = 88

Therefore, Tom's score on his fifth test was an 88%.

Answer:

42cm²

Step-by-step explanation:

*internal screaming* okay, let's go:

So, at this point, I don't even know what I'm doing, so I'm not going to guarantee that this is right, I'm sorry, but let's do some random math:

So we know that the length (the top and bottom) of the rectangle is 7 cm, we just have to figure out the width (the sides), and we're gonna do that by:

0.5 x 2 = 1

7 - 1 = 6

So now we just do the basic rectangle area calculation:

7 x 6 = 42

So, I hope that the area of the shaded area is 42cm²

if this is wrong, let me know so I can fix it

Answer:

C) increase by 0.25

Step-by-step explanation:

The expression with the smallest probability is: (C) P(z > 2), if z is a standard Normal random variable.

A z-core is also known as a standard score and it can be defined as a measure of the distance between a data point (raw score) and the mean, when standard deviation units are used.

In Statistics, z-scores can either be positive or negative and it is calculated by using this formula:

[tex]Z=\frac{x\;-\;u}{\delta}[/tex]

Where:

In this exercise, we would have the smallest probability for P(z > 2), when z is a standard Normal random variable.

Answer: 70 chickens

Step-by-step explanation:

7:2

Chickens to ducks

5:9

Ducks to pigs.

There are 36 pigs. 9 is the ratio of pigs.

5 : 9

? : 36

9 x 4= 36

So multiply 5x4 to find the total ducks

=20 ducks

7 : 2

? : 20

So, 2x10 is 20 (ducks)

So 7x10 to find the chickens

(You have to balence out the sides and keep it equal

So if one side is multiplied by 10, the other is too)

7x10

= 70 chickens

The number of chickens in the farm is 70 chickens

The ratio of chickens to ducks is

7:2

The ratio of ducks to pigs is

5:9

There are 36 pigs in the farm

The first step is to calculate the total number of ducks

9-5

= 4

= 5×4

= 20 ducks

The next step is to calculate the number of chickens

= 7×10

= 70 chickens

Hence there are 70 chickens in the farm

The equation could be used to determine the number of emails, y, that will be sent for a given round, x, is:

Step-by-step explanation:

To obtain the equation you must know how many emails will be sent in each case, taking into account that Jesse requested that each person copy and send the same email to 4 additional people, then:

How you can see, each round is the same that to multiply the last sent emails by four, so, with the equation selected in the answer we can obtain these results:

In the first round:

In the second round:

In the third round:

And, in the fourth round:

By this reason, the equation y = 4^X is the correct answer.
