11. If you randomly selected 500 U.S. homes, about
how many would be heated with fuel oil?
Answer:
50
Step-by-step explanation:
Given
Total number of US houses = 500
If 10% were affected by fuel oil
Total number affected by fuel oil = 10% of 500
Total number affected by fuel oil = 0.1 * 500
Total number affected by fuel oil = 50
Hence 50 houses were affected by fuel oil
Marie spent $15 on 4 identical jars of jelly. Each jar of jelly costs the same amount. How much did 1 jar of jelly cost? Use paper to show your work.
One jar of jelly costs $
Answer: $3.75
Step-by-step explanation:
First you would have to find the unit rate.
$15 / 4 jars of jelly = $3.75
Therefore, 1 jar of jelly = $3.75
Answer:
the answer is $3.75
Step-by-step explanation:
15 ÷ 4= 3.75
to verify your answer multiply
3.75 × 4= 15

This series of transformations is performed on a quadrilateral:
a dilation by a factor of 4 with the origin as the center of dilation
a reflection across the y-axis
a 90° counterclockwise rotation about the origin
a translation 3 units down
Arrange the functions representing these transformations in the order in which the transformations occur.
(The tiles are)
f(x, y) = (-4x, 4y)
g(x, y) = (4x, -4y)
h(x, y) = (4x, 4y)
i(x, y) = (4y, 4x − 3)
j(x, y) = (4y, 4x)
k(x, y) = (-4y, -4x)
l(x, y) = (-4y, -4x − 3)
Answer:
l(x,y) = (-4y, -4x - 3)Step-by-step explanation:
Let's start with function (x, y)
Transformations in the given order result in following
A dilation by a factor of 4 with the origin as the center of dilation
This results in both coordinates multiplied by 4(x, y) → (4x, 4y)A reflection across the y-axis
This results in x-coordinate changing sign to opposite(4x, 4y) → (-4x, 4y)A 90° counterclockwise rotation about the origin
This results in x-coordinate swapping with negative y-coordinate (-4x, 4y) → (-4y, -4x)A translation 3 units down
This results in y-coordinate change by -3(-4y, -4x) → (-4y, 4x - 3)The final function is:
l(x) = (-4y, -4x - 3)Answer:
l(x) = (-4y, -4x - 3)

Find the length of the third side. If necessary, round to the nearest tenth.
12
5
9514 1404 393
Answer:
13
Step-by-step explanation:
The hypotenuse can be found using the Pythagorean theorem. If we call that side 'c', then the theorem tells us ...
c² = 5² + 12²
c² = 25 +144 = 169
c = √169 = 13
The length of the third side is 13 units.
_____
Additional comment
The numbers (5, 12, 13) are what is called a "Pythagorean triple." That is, they are integers that can be used to form a right triangle. Others often seen in algebra problems are the (3, 4, 5), (7, 24, 25), and (8, 15, 17) triples. It can be worth your trouble to remember these. Then when you see side lengths of 5 and 12, you don't need to do any math to know the third side is 13.

Answer:
90
Step-by-step explanation:
Remeber there are 180 degress in a right triangle.
Answer:
y = 90°
Step-by-step explanation:
Y is 90 degrees. The base of the triangle seems to be bisected by a perpendicular bisector. The resulting angles are 90 degrees on both sides. And seeing as 90 is y, x is 20.
To be more precise. We know this is an isosceles triangle, due to the fact that the angle right of 110 must be 70 degrees (they are supplementary angles.) The entire triangle must add up to 180 by the triangle angles sum theorem, and two 70 degree angles add up to 140, meaning the last angle is 40 degrees. That final angle is bisected, meaning each part is 40/2, that's 20.

Answer:
[tex] \large \boxed{y = - \frac{2}{3} x + 2}[/tex]
Step-by-step explanation:
both slopes multiply each others must equal to -1 for perpendicular.
[tex] \large{m_1m_2 = - 1}[/tex]
Let m1 = 3/2
[tex] \large{ \frac{3}{2} m_2 = - 1} \\ \large{3m_2 = - 2} \\ \large{m_2 = - \frac{2}{3} }[/tex]
Therefore -2/3 is perpendicular to 3/2. Because the line passes through (6,-2)
[tex] \large{y - y_1 = m(x - x_1)}[/tex]
Given (x1, y1) = ordered pair
Therefore (x1, y1) = (6,-2)
and m = - 2/3
[tex] \large{y + 2 = - \frac{2}{3} (x - 6)}[/tex]
Write in slope-intercept form.
[tex] \large{y = - \frac{2}{3} x + 4 - 2} \\ \large{y = - \frac{2}{3}x + 2}[/tex]

A badminton tournament begins with 512 teams. If a team loses once, it is eliminated from competition. After the first round, 256 teams remain. After the 4th round, how many teams remain? How many rounds will be required to determine the champion?
Answer:
This is GP with the first term of 512 and common ratio of 1/2
The formula for nth term is:
aₙ = 512*(1/2)ⁿThe number of teams after the 4th round:
a₄ = 512*(1/2)⁴ = 32 teamsNumber of rounds to determine the champion:
1 = 512*(1/2)ⁿ2⁰ = 2⁹*2⁻ⁿ0 = 9 - n n = 9 roundsEric starts with 10 milligrams of a radioactive substance. The amount of the substance

How many cards are in a standard deck of cards? What are their colors?
Answer:
A standard deck of cards consists of 52 cards. The colors are usually black for the spades and clubs and red for the hearts and diamonds.
Step-by-step explanation:
Answer:
There are 52 cards which are either red or black
Step-by-step explanation:
A card is picked at random from a pack of 52 playing cards. The probability that it is a 6
Answer: 4/52 = 1/13
Step-by-step explanation: Every card in the deck has 4 suits which means that there will be 4 sixes in the deck so the probability will be any of the 4 out of the whole 52 or 1/13.

A bacterium triples in size every 6 minutes. If you start with 3 bacterium
in a dish, which of the following calculates the total amount of bacteria
after t hours?
3^t+1
3(2)^10t
3•3^t/6
3(2)^10t+1
None of the above
9514 1404 393
Answer:
E none of the above
Step-by-step explanation:
"Triples in size" means the growth factor is 3, so we expect to see that as the base of the exponent. That growth factor applies to a period of 6 minutes, or 1/10 hours. The number of 6-minute intervals in t hours is 10t, so we expect to see that as the exponent. The appropriate model could be written ...
