Answer:
362
Step-by-step explanation:
let the digits that make up the number be a, b and c with a in the hundred position, b in the tens and c in the units position. Given that
he hundreds digit is one more than the ones digit
a = c + 1
c = a - 1
and the tens digit is twice the hundreds digit
b = 2a
If the sum of the digits is 11
a + b + c = 11
substituting
a + 2a + a - 1 = 11
4a - 1 = 11
4a = 11 + 1
4a = 12
a = 12/4
= 3
recall that
c = a - 1 = 3 - 1 = 2
b = 2a = 2 * 3 = 6
Hence the number is 362

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?
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.

Write an explicit formula that represents the sequence defined by the following
recursive formula:
a1= -1 and an = an-1 – 6
Answer:
an = -6n + 5.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 = -1 and common difference d = -6
an = a1 + d(n-1)
an = -1 + -6(n - 1)
an = -1 -6n + 6
an = -6n + 5.

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
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.

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
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.

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?
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
