Mr. Miller created a graph of the number of emergency phone calls made to 9-1-1 during one week in January. Which statement describes Mr. Miller's data?

Answer:

This week her gross wage is equal to $216.25

Step-by-step explanation:

From the question it self we can make the following equation.

Let  "W" be the gross wage for the week.

Let  "V" be the value of the goods she sells.

then.....

W = $140 + 0.05V

(Where $140 is the price she will be paid for just working and 0.05V is the commission she will get paid this week)

Now that we know what "v" equal to, we can easily find out her Gross Wage this week by inserting in the value of V. And so we get.......

W = $140 + 0.05V

W = $140 + 0.05 x 1525

W = $140 + 76.25

W = $216.25

[tex]\Large\boxed{\tt Answer:~Isosceles~Triangle;~x=25}[/tex]

[tex]\tt Step-by-step~explanation:[/tex]

Since this triangle has two congruent angles/sides, we know that it is an isosceles. We can tell by looking at the markings on the triangles: The curves on both angles A and C indicate that they are congruent, and the markings on lines AB and CB also tell us that they are congruent.

To solve for x, we set up our equation like this:

[tex]\tt 4x-20=2x+30[/tex]

Since we know that lines AB and CB are congruent, that means 4x - 20 is equal to 2x + 30.

To solve, we can first subtract 2x from both sides and add 20 to both sides.

[tex]\tt 4x-(2x) -20=2x-(2x)+30\\2x-20+(20)=30+(20)\\2x=50[/tex]

Then, we divide both sides by 2 to isolate x.

[tex]\tt \frac{2x}{2} \frac{50}{2} \\x=25[/tex]

We can check if our answer is correct by plugging in our value for x into both expressions and see if they equal the same thing.

[tex]\tt 4(25)-20=80\\2(25)+30=80\\Correct[/tex]

Answer:

18

Step-by-step explanation:

Answer:

The value of a is 25

Step-by-step explanation:

When two angles are supplementary, they add up to 180 degrees

Mathematically,

(30 + 2a) + (125-a) = 180

30 + 2a + 125 - a = 180

a + 155 = 180

a = 180-155

a = 25 degrees

20-9=11

Answer:

since all sides are congruent the you could divide 180 by the because there are 180 degrees in a triangle

So the measure of angle R is 60 degrees

Answer:

[tex]x = \frac{-3}{4}[/tex] or  [tex]x = \frac{3}{2}[/tex]

Step-by-step explanation:

[tex]8x^{2} - 4x = 2x +9[/tex]

Okay, let's put everything on one side.

[tex]8x^{2} -4x-2x-9=0[/tex]

As you can see we can subtract -4x from -2x now leaving us with -6x.

[tex]8x^{2} -6x-9=0[/tex]

Now there are multiple ways to solve a polynomial, but we can go with a way to factor them the easy way. We need to multiply the leading coefficient with the ending term because there is no common number we can factor out of these guys.

[tex]8(-9)=-72[/tex]

We multiplied 8 and -9 together which gave us -72. With this, we need to find two numbers that add to the middle term, -6, but will multiply to -72. This is going to be 6 and -12. Now we are going to replace the middle coefficient with those two numbers.

[tex]8x^{2} + 6x - 12x- 9= 0[/tex]

(Keep in mind the equation has not changed)

Now we are going to do something called factoring by grouping, with the first two terms, 8x^2 and 6x we take out the GCF (greatest common factor):

[tex]2x(4x+3)[/tex]

so let's do the same between the last two.

[tex]-3(4x+3)[/tex]

So when putting them together we have,

[tex]2x(4x+3)-3(4x+3)=0[/tex]

Now let's factor here, (4x+3) can be taken out and 2x as well as -3 can be put together.

[tex](4x+3) (2x-3)=0[/tex]

Then we set these factors to zero to get our x answer:

[tex]4x+3=0[/tex]

[tex]2x-3=0[/tex]

And we solve, which leaves us with:

[tex]x = \frac{-3}{4}[/tex] or  [tex]x = \frac{3}{2}[/tex]

Answer:

40 feet represents the height of the tree ⇒ H

Step-by-step explanation:

Let us solve the question using the proportional

∵ A tree casts a shadow 64 feet long

∴ L[tex]_{T}[/tex] = 64 feet

∵ At the same time, a girl 5 feet tall standing near the tree

∴ H[tex]_{G}[/tex] = 5 feet

∵ She casts a shadow that is 8 feet long

∴ L[tex]_{G}[/tex] = 8 feet

The ratios between the shadows and the heights of the tree and the girl are proportional

∵ [tex]\frac{H_{T}}{H_{G}}[/tex] = [tex]\frac{L_{T}}{L_{G}}[/tex]

→ Substitute their values in the equivalent ratios

∴ [tex]\frac{H_{T}}{5}[/tex] = [tex]\frac{64}{8}[/tex]  

→ By using cross multiplication

∴ H[tex]_{T}[/tex] × 8 = 5 × 64

∴ 8H[tex]_{T}[/tex] = 320

→ Divide both sides by 8

∴ H[tex]_{T}[/tex] = 40 feet

∴ 40 feet represents the height of the tree

Answer:

Percentage of boy students is 45 per cent.

The total number of students is 480.

Step-by-step explanation:

To find the percentage of boy students, just subtract 55% (the percentage of girl students) from 100%, then you'll get 45%.

To find the total number of students, just use algebraic equation, rearrange it, and solve for x.

The workings are shown in the picture attached. Hope this helps!

Answer:

total of students is 480

Step-by-step explanation

let t = total of students.

if 55% of the students in school are girls.

then 45% of the students in the school are boys.

if there are 216 boys in school.

[tex]45\% \times t = 216 \\ t = \frac{216}{45\%} \\ t = \frac{216}{ \frac{45}{100} } \\ t = \frac{216 \times 100}{45} \\ t = 480[/tex]
