Answer:
The value of [tex]j[/tex]:
[tex]j = -56[/tex]
Step-by-step explanation:
Solve for [tex]j[/tex]:
[tex]\frac{j + 42}{-7} = 2[/tex]
-Multiply both sides by -7:
[tex]j + 42 = 2 ( -7)[/tex]
[tex]j + 42 = -14[/tex]
-Subtract both sides by 42:
[tex]j + 42 - 42 = -14 - 42[/tex]
[tex]j = -56[/tex]
So, therefore, [tex]x = -56[/tex] would be the final answer.
Answer:
j = -47
Step-by-step explanation:
I think you meant j + 42 - 2 = -7
So what I would do is first find the two number we know which would be
42 - 2 = 40
So, then the equation comes down to j + 40 = -7
So,
j = -47
Because = -47 + 40 = -7

Another candle has a volume of 75 cubic inches and a height of 6 inches. What is the radius, in inches, of this candle? Round your answer to the nearest inch. Use 3.14 for π.
Answer: 3 inches
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cone = 1/3 x π x radius^2 x height
Replacing with the values given:
75 = 1/3(3.14) r^2 (6)
Solving for r:
75 / (1/3 (3.14) 6) = r^2
75/ 6.28 = r^2
11.94 = r^2
√11.94 =r
3.45 inches = r
3 inches = r

Given the following exponential function, identify whether the change represents growth or decay , and determine the percentage rate of increase or decrease y =550(1.075)x
Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%
the zero of the polynomial 6x power 2 + 19 X - 77 is
Answer:
The zeros of the polynomial are x = 7 or x = -11/2
Step-by-step explanation:
The zeros of a polynomial refers to the solution of the polynomial.
6x^2 + 19x -77
6x^2-14x+ 33x -77
2x(x-7) + 11(x-7)
= (2x + 11)(x-7)
2x + 11 = 0
x-7 = 0
2x = -11
x = -11/2 = -5.5
and x-7 = 0
x = 7
So the zeros of the polynomial are x = 7 or x = -11/2

what is the solution for the inequality -3x + 2 < 11?
Start by subtracting 2 from both sides.
This gives us -3x < 9.
Now, divide both sides by -3.
However, when you divide both sides of an inequality by a negative number, you must switch the direction of the inequality sign.
So we have x > -3.

Wilson needs 9 pieces of wood that are each 1/3 ft long. He has one board that is 3 1/3 ft long. Will he be able to make all the pieces he needs from that one board?
Answer:
Yes, he will.
Step-by-step explanation:
Since he needs 9 pieces of 1/3 ft, yo would start by dividing 9 by 3 (9 x 1/3). This would give you 3, meaning that you would need 3 feet of would in all, and since he is given 3 and 1/3 feet, he has enough.

At 7 p.m. the temperature was 5° F. At midnight the temperature was -7° F. What was the change in temperature?
Answer:
Change in temperature was 12 degrees
Step-by-step explanation:
If you start with five degrees and end into negative 7 degrees, you can find the result within two steps
5 degrees minus 5 = 0 degrees
then, 0 degrees minus 7 = -7 degrees
Because you subtracted 5 from five, and 7 from seven, you add those two values together
7 + 5 = 12 degrees
So the change in temperature was 12 degrees

Tom can do a job in 4 hours while Sam can do it in 6 hours. How many hours would it take to complete this job if they work together?
Answer:
12/5hours=2.4 hours
Step-by-step explanation:
Sam:6hours
Tom:4hours
This is a rate problem
Sam's rate is one job completed in 6 hours which is 1/6
Tom's rate is one job completed in 4 hours which is 1/4
Together, they could complete 1/4+1/6 of the job in y hours
We are trying to find the rate at which Sam and Tom could complete the job together, or one job in x days, for a rate of 1/y
1/4+1/6=1/y
The least common denominator is 12y
Multiplying through by the LCD which gives:
12y(1/4)+ 12y (1/6)= 12y (1/y)
3y + 2y=12
5y = 12
y=12/5 hours=2.4hours
Therefore it will take 12/5 hours or 2.4 hours to complete the job if they work together
The amount of money that Tom had in his pension fund n 2016 was E55 000. Dis plans involve him putting $8 200 in his fund every year for the next 15 years. How much will Tom have in the pension fund in 2031?
Answer:
$178,000
Check my explanation for further details
Step-by-step explanation:
$8200 in his pension fund for 15 years
=8200×15
=$123,000
By 2031
Tom will have a total of $55 000+$123,000
=$178,000
If by saying E55,000 you mean 55,000 Euro
Then,
$62,174.99=E55000
$62,174.99+$123,000
=$185,174.99

A bicycle has a listed price of $736.99 before tax. If the sales tax rate is 9.75%, find the total cost of the bicycle with sales tax included
Round your answer to the nearest cent, as necessary.
Please help me
Answer:
First, we need to calculate the tax. So we can multiply 736.99*0.0975 which will give us 71.856525 or about 71.86. So then we add them together and we get an answer of 808.85. Therefore the answer to this question is.

Solve for q.
–15 − 18q = –20q + 15
q =
Answer:
q = 15
Step-by-step explanation:
→First, add 18q to both sides:
-15 - 18q = -20q + 15
-15 = -2q + 15
→Subtract 15 from both sides:
-30 = -2q
→Divide both sides by -2:
15 = q
We first want to get q on its own then solve like shown:
-15-18q=-20q+15
Now add 15 to both sides and add 20 q to both sides.
2q=30
Now divide 30 by 2.
q=15

Answer: True
Step-by-step explanation: The angles given are the same AND the side given us the same. The triangle has been reflected, but the reflection is still congruent.
The two triangles given are congruent according to the ASA congruence rule.
What is ASA congruence rule ?Two triangles are congruent if two angles and the included side of one triangle are equal to two angles and the included side of the other triangle.
Check whether the triangles are congruent :The given triangles are both right angled triangles.
The side 12 units is the included side between the angles 45° and 90° in both the triangles. This is the required condition for ASA congruence rule.
Hence we can say that the triangles are congruent according to the ASA congruence rule. The answer is A.True.

A scientist measured the wavelength of an X-ray as 0.0000000065 meters.
Write the number in scientific notation.
Answer:
6.5 * 10 ^ -9
Step-by-step explanation:
0.0000000065
Scientific notation means a* 10 ^b
where a is number between 1 and less than 10
Move the decimal 9 places to the right which means the power of 10 is negative since we moved the decimal to the right
6.5
The power of 10 is -9
6.5 * 10 ^ -9
Answer:
6.5 * 10^-9 metres.
Step-by-step explanation:
This is < 1 so the exponent is negative
We count the number of digits after the decimal point up to and including the first digit > 0.
This is 9 digits.
So the answer is 6.5 * 10^-9.
Cam is making a party hat, shown at left, in the shape of a cone for his
birthday. The circumference of the part of his head where the hat will
rest is 56 centimeters (cm). If the height of the hat is 25 cm, which of
the following is closest to the volume of Cam's hat, measured in cubic
centimeters (cm)?
Answer:
V≈2,080cm^3 Hope I helped :)
Step-by-step explanation:
The volume of a cone of radius r and height h is:
V=1/3πr^2h
Since the circumference of Cam's head is 56
2πr=56
r=56/2π
r=28/π
The volume of the hat is therefore:
V=1/3π(28/π )^2(25)
V=1/3((28)^2/π)(25)
V=1/3(19,600/π)
V≈2,080cm^3
The volume of the Cam's hat measured in cubic centimetres is 2081 cm³
Volume of a cone:The volume of a cone is as follows:
v = 1 / 3 π r²hwhere
h = height
r = radius
The circumference of the part of his head where the hat will rest is 56 cm. Let's find the radius
circumference = 2πr56 = 2 × π × rr = 28 / πh = 25 cm
V = 1 / 3 × π × (28 / π )² × 25
V = 1 / 3 × π × 784 / π² × 25
V = 19600 / 3π
V = 19600 / 9.42
V = 2080.67940552
V ≈ 2081 cm³
