Answer:
1. x = 58
2. x = 44
Step-by-step explanation:
#1:
2x + 5 + x + 2x + 7 + x = 360
Step 1: Combine 2x, x, 2x, and x to get 6x.
6x + 5 + 7 = 360
Step 2: Add 5 & 7 to get 12.
6x + 12 = 360
Step 3: Subtract 12 from both sides
6x = 360 - 12
6x = 348
Step 4: Divide both sides by 6.
x = 348/6
x = 58
#2:
3x + 2 + 2x + 2x + 1 + x + 5 = 360
Step 1: Combine like terms.
8x + 2 + 1 + 5 = 360
8x + 8 = 360
Step 2: Subtract 8 from both sides.
8x = 360 - 8
8x = 352
Step 3: Divide both sides by 8.
x = 352/8
x = 44

a circle has a radius of sqrt37 units and is centered at 1.3,-3.5
Answer:
80
Step-by-step explanation:
Answer:
(x-1.3)^2 + (y+3.5)^2 = 37
In general, (x-c)^2 + (y-k)^2 = r^2 where (c,k) is the center and r is the radius.
So if the circle with radius 5 has center (3,-4) then it's equation is:
(x-3)^2 + (y+4)^2 = 25
Notice that the second term is (y+4)^2 because the y-coordinate is -4 and y-(-4) = y+4
Which transformations are needed to change the parent cosine function to y = 3 cosine (10 (x minus pi))?
Answer:
See Explanation
Step-by-step explanation:
Given
New function: [tex]y = 3 \cos(10 (x -\pi))[/tex]
We can assume the parent function to be:
[tex]y = \cos (x)[/tex]
The new function can be represented as:
[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex]
Where
A = Vertical stretch factor
B = Period
C = Right shift
By comparison:
[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex] to [tex]y = 3 \cos(10 (x -\pi))[/tex]
[tex]A = 3[/tex]
[tex]c = \pi[/tex]
[tex]\frac{2\pi}{B} = 10[/tex]
Solve for B
[tex]B = \frac{2\pi}{10}[/tex]
[tex]B = \frac{\pi}{5}[/tex]
Using the calculated values of [tex]A,\ B\ and\ c.[/tex] This implies that, the following transformations occur on the parent function:

Answer:
Q5: S.A = 216 cm²
Q6: S.A = 254 cm²
Step-by-step explanation:
Q5:
Surface area of a cube = 6a²
a = 6 cm
Plug in the value of a
Surface area of the cube = 6(6²)
= 6(36)
S.A = 216 cm²
Q6:
Given:
Length (L) = 9 cm
Width (W) = 4 cm
Height (H) = 7 cm
Required:
Surface area
Solution:
Surface area of the rectangular prism = 2(LW + LH + HW)
Plug in the values
S.A = 2(9*4 + 9*7 + 7*4)
= 2(36 + 63 + 28)
= 2(127)
S.A = 254 cm²

Daniel bought a bicycle for $80 and a helmet for $20. The sales tax was 5%. How much did Daniel pay for the two items, including tax?
Given:
Daniel bought a bicycle for $80 and a helmet for $20.
Sales tax = 5%
To find:
The total amount of both items including tax.
Solution:
Price of bicycle (excluding tax)= [tex]\$80[/tex]
Price of helmet(excluding tax) = [tex]\$20[/tex]
Price of both items = [tex]\$80 + \$20[/tex]
=[tex]\$100[/tex]
Now, the sales tax is 5%. So,
Price of both items (including tax) = [tex]\$100+\dfrac{5}{100}(\$100)[/tex]
= [tex]\$100+\$5[/tex]
= [tex]\$105[/tex]
Therefore, the Daniel pays $105 for the two items, including tax.

Answer:
They played 4 games and paid $19
Step-by-step explanation:
4x + 3 = 2x + 11 (You basically have to solve for X)
4x - 2x = 11 - 3 (move like terms together)
2x = 8
x = (8/2)
x = 4
This means they had to play 4 games.
To get how much they paid, just plug 4 into any one of those given equations (They will both give the same answer).
4x + 3 ⇒ 4(4) + 3 = $19
To check if this is true,
2x + 11 ⇒ 2(4) + 11 = $19
Therefore, they paid $19
Answer:
$19 and played 4 games
If θ is an angle in standard position and its terminal side passes through the point (-7,-5), find the exact value of cot θ cotθ in simplest radical form.
Plot the point (-7, -5). We are in quadrant 3.
We also know that tan θ = opp/adj.
Cot θ = adj/opp.
Let us use a^2 + b^2 = r^2 to show you how to find r, the radius aka hypotenuse.
Look: (-7)^2 + (-5)^2 = r^2
If you should ever need to find r, do this:
(-7)^2 + (-5)^2 = r^2
(49) + 25) = r^2
74 = r^2
Take the square root on both sides of the equation to find r.
sqrt{74} = sqrt{r^2}
sqrt{74} = r
It is ok to simplify the sqrt{74} but not needed.
We now have the three sides of the triangle that is form in quadrant 3.
We can now read cot θ from the triangle itself.
So, cot θ = adj/opp = (-7)/(-5) or 7/5.
No need to find r but I simply wanted to show you how it's done in case you are given a question where r must be found.

Ms. Hernandez takes 56 students to the museum. Some of the students travel in a van and some travel on a bus. Going to the museum, the ratio of students in the van to students on the bus is 2 : 5 Going back to school, 2 students move from the van to the bus.
Answer:
I think we are missing part of the question.
But if it's looking for how many students rode the bus and van on the way to the museum when the ratio was 2:5, it's 16 students in the van and 40 students in the bus.
On the way home, it was 14 students in the van and 42 students in the bus, the ratio changes to 1:3

What is the perimeter of the circle with a missing sector of 40% and a radius of 3? 16.74 units 18.84 units 2.09 units d 22.74 units
Answer:
11.3097335 seems to have nothing with the question so the answer is
B) 18.8495559
Step-by-step explanation:
to find the perimeter (circumference?) do 2pi(r)
2 pi 3 = pi 6 = 18.8495559
since there is 40 percent missing, multiply the perimeter by 60% (part not missing)
18.8495559 * 60%
11.3097335

Take 45 + 90 then subtract the answer from 180
A local school board wants to determine if the proportion of households in the district that would support starting the school year a week earlier has changed from the previous year. Last year, the school board determined that 65% of households supported starting school earlier. They ask a random sample of 100 households this year, and 70% state they would support starting the school year earlier. Which hypotheses would determine if the proportion of households that support starting school earlier has changed this year?
Group of answer choices
H 0: p not-equals 0.70, H alpha: p = 0.70
H 0: p = 0.70, H alpha: p not-equals 0.70
H 0: p = 0.65, H alpha: p greater-than 0.65
H 0: p = 0.65, H alpha: p not-equals 0.65
Answer:
C
Step-by-step explanation:
Considering the situation, the hypotheses set that would determine if the proportion of households that support starting school earlier has changed this year is given by:
[tex]H_0: p = 0.65, H_\alpha: p \neq 0.65[/tex]
What are the hypotheses tested?At the null hypotheses, it is tested if there has been no change, that is, the proportion is still of 0.65 = 65%, hence:
[tex]H_0: p = 0.65[/tex]
At the alternative hypotheses, it is tested if there has been a change, that is, the proportion is not of 0.65 = 65% anymore, hence:
[tex]H_\alpha: p \neq 0.65[/tex]

What is the length of bc in the right triangle?
Answer:
D.39
Step-by-step explanation:
Pythagorean Theorem: a^2+b^2=c^2 (Where a and b are the legs of the triangle and c is the hypotenuse)
Using this:
(AB)^2+(AC)^2=(BC)^2 (Pythagorean theorem)
15^2+36^2=(BC)^2 (Substitution)
225+1296=(BC)^2
(BC)^2=1521
BC=39
Answer:
D. 39
Step-by-step explanation:
The three interior angles of a right triangle always have a sum of 180°, and right angles always equal 90°.
Adding the angles shown here,
36+15+90 = 141
And, 180 - 141 = 39°.
Therefore, the length of angle BC is 39°.

1. In the following inequality, x = -2, what type of circle would appear on the number line (open
or closed circle) and in which direction would the arrow point on the number line(right or left)?
Also, what is a possible solution to x2 -2?
Please answer all of the questions in sentence form. *
Answer:
For number one it would be a closed circle poiting to the left because it is a negative number and it is not equal to or less than anything.
For number 2 a possible solution will be 2^2-2 which would equal 2 because 2^2=4 then 4-2=2
