Jim currently has $1,250 in his bank account and Sally has $1,400 in her bank account. Jim deposits $27.50 per week and Sally deposits $20 per week into her account. After how many weeks will they have the same amount of money? Jim and Sally will have the same amount of money after nothing week(s). (Type an integer or a decimal.)
Answer:
20 weeks.
Step-by-step explanation:
The equations of money deposits of each bankholder as a function of time are, respectively:
Jim
[tex]p_{1} = 1250 + 27.50\cdot t\\[/tex]
Sally
[tex]p_{2} = 1400 +20\cdot t[/tex]
The number of weeks so that both have the same amount of money is:
[tex]1250 + 27.50\cdot t = 1400 + 20\cdot t[/tex]
[tex]7.50\cdot t = 150[/tex]
[tex]t = 20[/tex]

Residents of a small city voted on whether
to allow a developer to build a shopping
center. The number of votes in favor of the
shopping center was 3,400. The number of
votes against the shopping center was 15,600.
What percent of the voters were in favor of
building the shopping center?
What percent of the voters were against of
building the shopping center?
Add the two numbers together to find total votes:
3,400 + 15,600 = 19,000 total votes.
Divide votes for by total votes:
3,400 / 19,000 = 0.1789
Multiply by 100:
0.1789 x 100 = 17.89% voted for it.
Subtract the percent that votes for it from 100%
100% - 17.89% = 82.11% voted against it.
The answers probably need to be rounded, so 18% for, and 82% against.
Two parallelograms are similar. The base of the first is 12cm, and its height is 8 cm. Find the base of the second parallelogram if its height is 34 cm.
Answer:
The base of the second parallelogram is 51cm.
Step-by-step explanation:
If the parallelograms are similar, it means by applying the same scale factor to all the sides in one gives you the other. The question tells us the height of the first shape is 8cm and the height of the second shape is 34cm. That means the scale factor is:
[tex]\frac{34}{8}=4.25[/tex]
Apply this same scale factor to the base of the first shape to find the base of the second:
[tex]12 \times 4.25=51[/tex]

Answer:
The value if x is 0.9875.
Step-by-step explanation:
First, we have to get rid of brackets by expanding :
[tex]0.5(2x + \frac{3}{4} ) - \frac{1}{3} (0.1 + x) = 1[/tex]
[tex]0.5(2x) + 0.5( \frac{3}{4} ) - \frac{1}{3} (0.1) - \frac{1}{3} (x) = 1[/tex]
[tex]x + \frac{3}{8} - \frac{1}{30} - \frac{1}{3} x = 1[/tex]
Next you have to collect like terms :
[tex]x - \frac{1}{3} x + \frac{3}{8} - \frac{1}{30} = 1[/tex]
[tex] \frac{2}{3} x + \frac{41}{120} = 1[/tex]
Lastly, you can solve x :
[tex] \frac{2}{3} x = 1 - \frac{41}{120} [/tex]
[tex] \frac{2}{3} x = \frac{79}{120} [/tex]
[tex]x = \frac{79}{120} \div \frac{2}{3} [/tex]
[tex]x = \frac{79}{80} [/tex]
[tex] x = 0.9875[/tex]
The price of a computer was decreased by 7% to £500. What was the price before the decrease? Give your answer to the nearest penny.
The original prize of the computer is £537.63.
The given parameters:
Final prize of the computer, y = £500Percentage decrease in prize, = 7% = 0.07Original prize of the computerThe original prize of the computer is calculated as follows;
Let the original prize of the computer = x
y = x(1 - 0.07)
500 = x(1 - 0.07)
500 = 0.93x
divide both sides by 0.93

of alien races think invading Earth is a bad idea.
What percent of alien races think invading Earth is a bad idea?
Answer: 90%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 9/10 as a percent, we need to find a fraction
equivalent to 9/10 that has a 100 in the denominator.
We can do this by setting up a proportion.
So we have [tex]\frac{9}{10} = \frac{n}{100}[/tex].
Now, we can use cross-products to find the missing value.
So we have (9)(100) which is 900 is equal to (10)(n) or 10n.
So we have 900 = 10n.
Next, dividing both sides of the equation by 10, we have 90 = n.
So, 9/10 is equal to 90/100 or 90%.
Answer:
90%
Step-by-step explanation:
9/10 times 100 is 90%

If a class has 14 out of 30 students are boys, it has 30 - 14 = 16 girls
ratio of the number of boys to the number of girls means = [tex]\frac{Boys}{girls}[/tex]
Because, firstly it's saying ''boys'' , after ''girls''

[tex]y = {x}^{2} - 6x + 8[/tex]
Let x = 0,
[tex]y = {0}^{2} - 6(0) + 8[/tex]

Answer:
1/12 ( -x -4 )
Step-by-step explanation:
1/12 ( -x - 4 )
1/12(-x) = -1/12x Multiply 1/12 and -x to get -1/12x.
1/12 x -4 = -1/3 Multiply 1/12 and -4 to get -1/3.
So, therefore, the expression 1/12 ( -x - 4 ) is equivalent to -1/12x - 1/3.

You spin the spinner twice.
What is the probability of landing on a 4 and then landing on a 4?
Simplify your answer and write it as a fraction or whole number.
Answer: 1/16
Step-by-step explanation: It's important to understand that the two spins are called independent events because the outcome of the first spin does not affect the outcome of the second spin.
To find the probability of independent events, we first find the probability of each event, then we multiply the probabilities together.
Since there is one 4 on the spinner and four possible outcomes, each of which is equally likely, the probability of spinning a 4 is 1/4.
This mens that 1/4 is the probability of
getting a 4 on the second spin too.
Now we multiply.
1/4 x 1/4 gives us 1/16.
So the probability of spinning a 4 twice is 1/16.

Slope is calculated by [tex]\frac{y1-y2}{x1-x2}[/tex] so now you put the points (-10,4) and (-10,8) into that.
Since both x values are the same you can tell that the line is a vertial line meaning the slope is undefined.

If Rosetta sells her house and pays off the mortgage, how much should she receive (assuming there are no other costs associated with selling the house)?
$42,000
$50,000
$52,000
$60,000
Answer:
$50,000
Step-by-step explanation:
The computation of the amount received after paying off the mortgage is shown below
= Value of the house - mortgage amount
= $150,000 - $100,000
= $50,000
By deducting the mortgage amount from the value of the house we can get the amount received and the same is shown in the computation part
Since in the question it is given that the Rosetta sells her house and paid off mortgage so only these two items are considered and others are to be ignored

What is the volume of the pyramid?
12 in
8 in
10 in
120 in
320 in
480 in
960 in
Answer:
B. 320 inches cubed
Step-by-step explanation:
A pyramid's volume is denoted by: V = (1/3) * B * h, where B is the base area and h is the height.
Here, the base is a rectangle with dimensions 10 inches by 8 inches. The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. The length is 8 and the width is 10, so plug these in:
A = lw
A = 8 * 10 = 80
So, we know that B = 80.
We are also given that the height is h = 12, so plug these values into the volume formula:
V = (1/3) * B * h
V = (1/3) * 80 * 12 = 320
The answer is thus B.

32
6
24
12
Answer:
the answer is 12 degrees
The measure of angle ACB when the secant BC and the tangent AC intersect is 12°
Secant and Tangent intersectionWhen a secant and a tangent meet outside the circle, thwe product of the length of the secant and its external segment equals the square of the length of the tangent segment.
Therefore,
arc XA = 2(64) = 128 degrees.
Hence,
m∠C = 1 / 2 (152 - 128)
m∠C = 1 / 2 (24)
m∠ACB = 12°
Therefore, angle ACB is 12 degrees.
