manufacturing C is $65. Please don’t send me links. Don’t send links. I will give brainlist out to whoever answers it correctly. No links please. nO LINKS.
Let's solve
C=2p+35PutC=65
2p+35=652p=65-352p=30p=15$Answer:
The value of p = $15
Step-by-step explanation:
Given equation is C = 2p + 35
and the C is $65
Putting the value of c in equation
=> 65 = 2p + 35
=> 65-35 = 2p
=> 30 = 2p
=> 30/2 = p
=> p = 15$

Delta Math: Angle Terminology with Equations
Answer:
m∠A = 139°
Step-by-step explanation:
Since knowing that:
Supplementary angles = 180 degree
Thus we put that in both equation:
( 7x - 15 ) + ( 2x - 3 ) = 180
Combine like terms & use inverse operations to find the value of x:
( 7x - 15 ) + ( 2x - 3 ) = 180
9x - 18 = 180
9x - 18 + 18 = 180 + 18
9x = 198
9x/9 = 198/9
x = 22
Hence, Angle A will have a measure of 7x - 15 which means 7 × 22 -15 = 154 - 15 = 139°
m∠A = 139°
The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
m∠ B = 41°
Check Answer by add 139 and 31 which equal 180

A toy ball can be modeled as a sphere. Eva measures its diameter as 15.7 cm. Find the
ball's volume in cubic centimeters. Round your answer to the nearest tenth if necessary
Answer:
[tex]v = 2064.2 {cm}^{3} [/tex]
Step-by-step explanation:
we first consider the formula for the volume of a sphere
[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
we were given diameter of 15.7cm.
we can find the radius by dividing the diameter by 2
because two times a radius makes a diameter.
[tex] \frac{15.7}{2} = 7.9cm[/tex]
we have the radius as 7.9cm.
and we know pi (π) to be 3.14 or 22/7.
but in this case, we use 3.14.
now let's substitute the values in the formula
[tex]v = \frac{4}{3} \times 3.14 \times {7.9}^{3} [/tex]
and we will get
[tex]v = 2064.19 {cm}^{3} [/tex]
but the nearest 10th will be
[tex]v = 2064.2 {cm}^{3} [/tex]

The hypothesis illustrates that C. Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.
How to illustrate the information?Using a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:
tInterval 9.68,1.23,125,0.99
It resulted in 9.68 ± 0.287805.
Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.
Therefore, the researcher failed to reject the null hypothesis.

Tank A fills at a rate of 6 gallons per hour and discharges water at a rate of 69 gallons per day. If the tank starts out empty, how much water would be in the tank after 24 hours
The tank fills up at a daily rate of
(6 gal/hr) (24 hr/day) = 144 gal/day
so the net rate is
144 gal/day - 69 gal/day = 75 gal/day
and after 24 hours, the tank would contain 75 gal of water.
75 gallons of water would be in the tank after 24 hours.
How to elaborate the problem ?
Tank A fills at a rate of 6 gallons/hr
We know that, 1 day = 24 hours
So, Tank A fills in a day = (6 × 24) gallons
Given that, The tank discharge water at a rate 69 gallons per day.
How much water would left after 24 hours ?Total water in the tank A in 24 hours = 144 gallons
Tank A discharge water in 24 hours = 69 gallons
∴ Water left in the tank A after 24 hours = (144-69) gallons
= 75 gallons

solving,

or, 9x + 18 = 180
or, x + 18 = 180/9
or, x + 18 = 20
or, x = 20 - 18

Distributed property 3(4x-5)
Answer:
Answer below!
Step-by-step explanation:
Alright I'm not too sure on what the question is asking for per your instructions, but I've written out my best explanation on how to use distributive property to solve this equation.
So first, what is the process of distributive property? It basically states whatever is in the parenthesis is multiplied by the outside number.
In simpler terms, each character in the parenthesis is multiplied by the number standing outside of the parenthesis.
So we can go...
(3 x 4x) - (3 x 5) = (12x) - (15)
And there's your answer, 12x - 15! Unless you know what x means, you'll probably just stop there.

which angle has its terminal side on the positive y-axis?
2pi radians
pi radians
pi/2 radians
3 pi/2 radians
Answer:
[tex]\sf \dfrac{\pi}{2}[/tex]
Step-by-step explanation:
Angles are measured in a counterclockwise direction from the positive x-axis (initial side).
Therefore, if an angle's terminal side is on the positive y-axis, the angle will be 90° or [tex]\sf \dfrac{\pi}{2}[/tex] radians.
See attached diagram for visual explanation.
If the angle was [tex]\pi[/tex] then the terminal side would be on the negative x-axis.
If the angle was [tex]\dfrac32\pi[/tex] then the terminal side would be on the negative y-axis.
If the angle was [tex]2\pi[/tex] then the terminal side would be on the positive x-axis and the angle would be one complete revolution of the circle.

Answer:

And
-11-11 has the sum of -22
16,48,144,...
Find the 6th term.
Step-by-step explanation:
16, 48, 144
hmmm.
the first thing that comes to mind : it cannot be an addition, as the difference between the 2nd and 3rd numbers is much bigger than the difference between the 1st and 2nd numbers.
so, we try multiplication.
and I see : 16×3 = 48
aha !
48×3 = 144
ok, we found it. the sequence is clearly created by multiplying always the previous number by 3.
so, we have 2 main choices to get the 6th term :
1. simply calculate 144 ×3×3×3 (3 times to get from the 3rd to the 6th term).
2. define the sequence formula and calculate for the 6th term.
1.
144 × 3×3×3 = 144 × 27 = 3,888
2.
a1 = 16
a2 = a1×3 = 16×3 = 48
a3 = a2×3 = a1×3×3 = 16×9 = 144
an = a1 × 3^(n-1) = 16 × 3^(n-1)
a6 = 16 × 3⁵ = 16 × 243 = 3,888

Using compound interest, it is found that Claire will have $6,186 in her account when Henry's money has tripled in value.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.For Henry, we have that r = 0.0675, n = 12. The time it takes for the amount to triple is t when A(t) = 3P, hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]3P = P\left(1 + \frac{0.0675}{12}\right)^{12t}[/tex]
[tex](1.005625)^{12t} = 3[/tex]
[tex]\log{(1.005625)^{12t}} = \log{3}[/tex]
[tex]12t\log{(1.005625)} = \log{3}[/tex]
[tex]t = \frac{\log{3}}{12\log{(1.005625)}}[/tex]
t = 16.32.
Then, for Claire, we have that the parameters are as follows:
P = 2300, r = 0.0625, n = 1, t = 16.32.
Hence, the amount is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]A(t) = 2300\left(1 + \frac{0.0625}{1}\right)^{16.32}[/tex]
A(t) = 6186.
Claire will have $6,186 in her account when Henry's money has tripled in value.
