Answer:
7/11
Step-by-step explanation:
Let X equal the decimal number
Equation 1:
X=0.63¯¯¯¯¯
With 2 digits in the repeating decimal group,
create a second equation by multiplying
both sides by 102 = 100
Equation 2:
100X=63.63¯¯¯¯¯
Subtract equation (1) from equation (2)
100XX99X===63.63...0.63...63
We get
99X=63
Solve for X
X=6399
Find the Greatest Common Factor (GCF) of 63 and 99, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 9,
63÷999÷9=711
Therefore
X=711
In conclusion,
0.63¯¯¯¯¯=711

Tammy bought 6 CDs that were each the same price. Including sales tax, she paid a total of $94.80. Each CD had a tax of $0.05. What was the price of each CD before tax?
Answers
Answer:
$15.75
Step-by-step explanation:
first, figure out the value of the tax. that would be 0.30 because there are 6 cds, and each has a tax of 0.05. next, subtract the tax from the total. that would be 94.50. this gives us the price of the cds alone. lastly, divide the toal by 6. 94.50/6=15.75.

Suppose real gdp is 13.2 and potential real gdp is 14.0, with a gap of $800 billion. The government purchases multiplier is 5.0, and the tax multiplier is 4.0. How much will government purchases need to be increased to bring economy to equilibrium at potential GDP?
Answers
Answer: $160 billion
Step-by-step explanation:
The government purchases multiplier refers to the increase in real GDP in dollar terms as a result of a dollar of government purchases in the economy. For instance, if the multiplier is 5 and the government spends $10, real GDP increases by: 5 * 10 = $50
The gap here is $800 billion. Given a government purchases multiplier of 5.0, the amount that the government needs to spend is:
= Gap / Multiplier
= 800 / 5
= $160 billion

Which of the statement(s) about the graph shown are true? Select all that apply.
a. An equation for the graph is y=2x^2-9x+7
b. the function has two roots
c. The solutions of the related quadratic equation are -1.5 and -3
d. The related quadratic equation has two solutions
Answers
Step-by-step explanation:
The solutions of the related quadratic equation are -1.5 and -3
To summarize, the true statements are:
(b) The function has two roots.
(d) The related quadratic equation has two solutions.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
To determine which statements about the quadratic function that passes through (1,0) and (3.5,0) are true, we need to use the fact that the roots (or x-intercepts) of a quadratic function can be found by solving the related quadratic equation, which is obtained by setting the function equal to zero.
Let's start with a statement (a). Plugging in the two points given into the equation y = 2x^2 - 9x + 7, we get:
At x = 1, y = 2(1)^2 - 9(1) + 7 = 0
At x = 3.5, y = 2(3.5)^2 - 9(3.5) + 7 = 0
This confirms that points (1,0) and (3.5,0) are indeed on the graph of the function, but it doesn't tell us whether this is the only function that passes through those points. So statement (a) alone is not sufficient to determine the true statements.
Next, let's consider statement (b). Since the graph passes through (1,0) and (3.5,0), we know that it must cross the x-axis at those two points. Therefore, the function has two roots or x-intercepts. Statement (b) is true.
Moving on to statement (c), we need to find the solutions of the related quadratic equation. Setting y = 2x² - 9x + 7 equal to zero, we get:
2x² - 9x + 7 = 0
Using the quadratic formula, we find that the solutions are:
x = (9 ± √(9² - 4(2)(7))) / (2(2)) ≈ 2.5 and ≈ 1.75
Therefore, statement (c) is false.
Finally, statement (d) asks whether the related quadratic equation has two solutions. We just found that it has two solutions, so statements (b) and (d) are true.

____________________Solution :-Given Information :- Base of Triangle = 12 ftBase² = 12² = 144 ftAltitude of Triangle = 8 ftAltitude² = 8² = 64 ftTo Find :- Hypotenuse of Triangle Formula Used :- Pythagoras Theorem ↓Hypotenuse² = Base² + Altitude²Calculation :-Here, we will substitute the given values in the formula,
⇒ Hypotenuse² = ( 144 + 64 ) ft
⇒ Hypotenuse² = 208 ft

long until you have about 41 mg of caffeine?
Answers
Someone who consumes 40 milligrams (mg) of caffeine will have 20 mg remaining in their system after 5 hours.
When do effects peak?
Levels of caffeine peak in the blood within about 15–45 minutes of consumption.
They are then quickly metabolized by the liver.
Most people notice the strongest effects during this time, and many report feeling jittery, needing to urinate, and having sudden bursts of energy. These symptoms tend to go away as the caffeine starts to break down.

This room has scratch marks on the floor. Tyler wants to slide the rug over to cover the scratch marks. What kind of translation should he perform that will conceal the scratches?
A.) Reflection
B.) Rotation
C.) Translation
D.) Dilation
Answers
Answer:
Option C
Step-by-step explanation:
To cover the scratch mark Tyler will move the rug so that it covers the mark.
Area of the rug = Length × Width
= (2 units) × (3 units)
= 6 square units
Area of the block in which the scratch mark is given
= 2 × 3
= 6 square units
Option A).
Reflection
If we reflect the rug across x or y axis image will be in other quadrants.
Therefore, Reflection is not the answer.
Option B).
Rotation
Rotation of the rug will move it to other quadrants or the size of the image will not cover the scratch mark.
Therefore, Rotation is not the answer.
Option C).
Translation
By shifting the rug to the required place we can cover the scratch mark.
Therefore, Translation will be the answer.
Option D).
Dilation
Dilation of the rug will differ the size.
Therefore, Dilation will not be the answer.
Option C will be the answer.
