Answer:

60

Step-by-step explanation:

At the time of launch, x will be 0 because the object hasn't been thrown yet. Therefore, its height will be 60.

Answer:

The answer for it is 60.

Step-by-step explanation:  

5*0+20*0+60

And due to the simplification by keeping the value 0 in place of x. So if any term is multiplied with 0 the value of that term will be 0. So by adding 0+0+60 . Therefore , the height will be 60 .

More explanation:

At the time of launch, x will be 0 because the object have not  been thrown yet.So its height will be 60.

Answer:

Fair

Step-by-step explanation:

Based on the description provided in the question it is safe to say that the survey that Paula conducted is completely Fair. This is mainly due to the fact that her pool of participants are completely random. Paula does not control who will walk through the schools doors first. Therefore she cannot be biased since she is surveying whoever walks through the doors first regardless of her personal opinions or feelings.

Answer:

It is the third one

Step-by-step explanation

3 times 3 equals 9.

By solving Power equation, answer of the equation [tex]\frac{(3x)^2x^4y}{x^5}[/tex] is 9xy³.

The power is "a number says how many times to use the number in a multiplication".

According to the question,

[tex]\frac{(3x)^2x^4y}{x^5}[/tex]  = [tex]\frac{9x^2y^2x^4y}{x^5}[/tex]    [using power equation]

            = 9xy².

Answer:

It has the same slope and a different y-intercept

Step-by-step explanation:

Y + 11 = -(x-18)

Y + 11 = -x + 18

Y = -x +7

thus it has a slope of -g too but y-intercept was 7 instead of 13

Answer: y=8x+6

Step-by-step explanation:

The equation for a line is y=mx+b, where m is your slope and b is the y intercept of the line. Hope this helps!

Using the law of sins:

B =sin^−1((sin(A)⋅a)/b) = sin^−1((sin(65)⋅110)/155)=40.03 degrees

B= 40.03 degrees (round as needed)

Answer:

A y = -3/4x + 6

Step-by-step explanation:

We know that the plot decreases from left  to right so the slope is negative

That eliminates choices B and D

We also know that the y intercept is between 5 and 8  

That eliminates choice C

Answer:

B, C, and F

Step-by-step explanation:

Answer:

h = 9

Step-by-step explanation:

You can use the Pythagorean theorem to solve this.  Consider each half of the main triangle their own triangles.  

h = a

a^2 + b^2 = c^2

or

a^2 = c^2 - b^2

a^2 = 10^2 - 5^2

a^2 = 100 - 25

a^2 = 75

a = √75

a = 8.66, or 9

h = 9 (when rounded)

Answer:

80 (I think)

Step-by-step explanation:

I would just go to x=7 and look up until i reach the line of best fit. The intersection is at y=80

The score of student is 80 marks if she studied for 7 hours.

Given,

The scatter plot shows the time spent studying compared to test scores for Mr. Stone’s eighth-grade class. From the plot it is clear that time is shown on x  axis and test scores is shown on Y axis.

We have to predict the score that a student would earn if he studied for 7 hours.

Here look at the Scatter plot we find that 7 hours is on x axis and the respective line of best fit of test score is passing through score 80.

Hence if a student is studied for 7 hours he would earn 80 marks.

Answer:

Step-by-step explanation:

Let x be the number of students that like both algebra and geometry. Then:

1. 45-x is the number of students that like only algebra;

2. 53-x is the number of students that like only geometry.

You know that 6 students do not like any subject at all and there are 75 students in total.

If you add the number of students that like both subjects, the number of students that like only one subject and the number of students that do not like any subject, you get 75.

Therefore,

[tex]x+45-x+53-x+6=75.[/tex]

Solve this equation:

[tex]104-x=75,\\\\x=104-75,\\\\x=29.[/tex]

You get that:

29 students like both subjects;

45-29=16 students like only algebra;

53-29=24 students like only geometry;

24+6=30 students do not like algebra;

16+6=22 students do not like geometry.

a = 29, b = 16, c = 24, d = 30, e = 22

Answer:

Volume: 105 cubic centimeters

Mass of doorstop: 924 grams

Step-by-step explanation:

First, you need to find the area of the triangular base of the prism. The area of the triangle is bh/2=10*6/2=30 square centimeters. Multiplying this by the height of the doorstop of 3.5, you get a total volume of 105 cubic centimeters. Since each cubic centimeter weighs 8.8 grams, the whole thing weighs 105*8.8=924 grams. Hope this helps!

Answer:

volume 105 cm³

mass 924 g

Step-by-step explanation:

This is triangular prism so (Volume) V = (Area of base) B * (Height) H

In this case is triangle is the base shape with base b =10cm and height h= 6cm so

B =1/2 bh = 1/2 *10*6 =30 cm²

(Height) H = 3.5 cm

so V = 30*3.5 = 105 cm³

1 cm³ has a mass ≈ 8.8g

so the mass of the doorstop is volume * mass per cm³

105 * 8.8 = 924 g

4x^4-3

4x³

Answer:

4x^3

Step-by-step explanation:

In the numerator, (top part) we have 2x^4 times 6x^2

2 times 6 is 12, and x^4 times x^2 is x^6.

Thus, in the top part, we have 12 times x^6.

In the bottom part we have 3 times x^3.

This is exactly the answer for d, but this is not a simplified answer.

Dividing 12 by 3 we have 4, and x^6/x^3 gives us x^(6-3) which is x^3.

Therefore, we have the correct answer: 4x^3

Step-by-step explanation:

let the recurring decimal be (n)

we need to find a number that will subtract the number to remove the decimal

the nearest number is 16.666...

because the decimal has moved one step ahead, we will call the new number (10n)

16.666 - 1.666 = 15.

1900 ≥50 + .40 *4100

Step-by-step explanation:

Cost = rush fee + cost per brochure * number of brochures

 cost= 50 + .40 * b where b is the number of brochures

This must be less than or equal to 1900 dollars

1900 ≥50 + .40 * b

We are getting 4100 brochures

1900 ≥50 + .40 *4100

1900≥50 + 1640

1900 ≥1690

Answer:

This guy is a fooooool the real answer is

Step-by-step explanation:

x=8 and y=−1

so : (8,-1)

From the system of equation 2x + 4y = 12 and  y equals StartFraction one-fourth EndFraction x minus 3. The solution to the system of equations in terms of (x, y) is equal to ( (8, -1)

The system of equations is given as:

2x + 4y = 12        -------  (1)

[tex]\mathbf{y = \dfrac{1}{4}x - 3} \ \ \ ----(2)[/tex]

So, from equation (1), we will replace the value of y which is [tex]\mathbf{ \dfrac{1}{4}x - 3} }[/tex] in order to be able to solve for x.

i.e.

[tex]\mathbf{2x + 4\Big ( \dfrac{1}{4}x -3 \Big) = 12 }[/tex]

Open brackets

2x + x -12  = 12

3x - 12 = 12

3x = 12 + 12

3x = 24

x = 24/3

x = 8

Now, we will replace the value of x into equation (2) to be able to solve for y.

[tex]\mathbf{y = \dfrac{1}{4}(8) - 3} }[/tex]

y = 2 -3

y = -1

Therefore, the solution to the system of equations in terms of (x, y) is equal to ( (8, -1)
