Answer:
10x + 19
Step-by-step explanation:
The expression 2(5x + 6) can be simplified to 10x + 12, and when that is combined with 7, the result is 10x + 19.
Answer: First, distribute the 2 to the parentheses:
2 * 5x + 2 * 6 + 7 = 10x + 12 + 7
Next, combine like terms:
10x + 12 + 7 = 10x + 19
So the result is 10x + 19.

The following sample space could represent which repeated experiment?
S: {BY, YB, BB, YY}
A: Flipping a fair coin once
B: Rolling a number cube twice
C: Spinning a spinner once with 2 equal sections colored blue and yellow
D: Spinning a spinner twice with 2 equal sections colored blue and yellow
The sample space S = {OB, BB, BO, OO} represents the outcome of spinning a spinner twice with two equal sections colored brown (B) and orange (O).
What is the repeated experiment?Getting the same result when an experiment is repeated is called replication. If research results can be replicated, it means they are more likely to be correct. Repeated replication of investigations may turn a hypothesis into a theory.
here, we have,
In this experiment, each spin of the spinner results in either a brown or an orange section being selected. Since the spinner is spun twice, there are four possible combinations of results: OB (orange followed by brown), BB (brown followed by brown), BO (brown followed by orange), and OO (orange followed by orange). These four possible combinations make up the sample space S.
The correct option is A.
So the repeated experiment represented by the sample space S is spinning a spinner twice with 2 equal sections colored brown and orange.

b. 4 1/2 feet
c. 12 3/4 feet
d. 13 1/4 feet
13 1/4
4.5 into a fraction is 4 1/2. 4 1/2 + 8 3/4 is 13 1/4 feet.
Answer:
The answer is d. 13 1/4 feet PLEASE MARK BRAINLIEST
Step-by-step explanation:
the 8 feet plus the 4 feet from the 4.5 feet makes 12 feet plus the fractions so 8 inches is 1/4 feet and 8 inches plus 5 inches on the 4.5 feet makes 13 inches which is 13 1/4 feet so 8 3/4 feet + 4.5 feet = 13 1/4 feet

A party planner organized a dinner party. The party planner recorded the height of the candlesticks over time and graphed the relationship.
graph with the x axis labeled time in hours and the y axis labeled height of candlestick in inches and a line going from the point 0 comma 9 through the point 3 comma 7
Find and interpret the slope and y-intercept in this real-world situation.
The slope is negative two thirds, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases two thirds of an inch every hour.
The slope is negative three halves, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases three halves of an inch every hour.
The slope is 9, and the y-intercept is negative two thirds. The candle starts at a height of two thirds of an inch and decreases 9 inches every hour.
The slope is 9, and the y-intercept is negative three halves. The candle starts at a height of three halves of an inch and decreases 9 inches every hour.
Answer:
(a) The slope is negative two thirds, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases two thirds of an inch every hour.
Step-by-step explanation:
You want to find the y-intercept and slope from the given graph of candle height versus time.
Y-interceptThe y-intercept is the point on the y-axis where the graph intercepts the y-axis. This graph has a y-intercept of 9 inches, the height of the candle when it starts burning.
SlopeThe slope of the graph is the ratio of "rise" to "run". Here, we can see that over a period of 3 hours, the candle loses 2 inches in height. That means the slope is ...
slope = rise/run = (-2 in)/(3 h) = -2/3 in/h
This slope means the candle height decreases 2/3 inch every hour.
__
Additional comment
Your problem statement identifies points on the graph as (0, 9) and (3, 7). These are actually the points where we drew the "rise" and "run" lines in the attachment. They are points where the line crosses grid intersections, which are the best choice for finding slope.
The slope can be found algebraically as ...
m = (y2 -y1)/(x2 -x1) = (7 -9)/(3 -0) = -2/3
We find it is often easier to count grid squares.
I had a simalar question where it was the same this but with 8 as the intercept sooooo it's c if ur looking for the answer hope this helps "The slope is negative two thirds, and the y-intercept is 8. The candle starts at a height of 8 inches and decreases two thirds of an inch every hour."

The price of oil decreased from $54 per barrel to $50 per barrel. What was the percent decrease in oil prices?
The percent decrease in oil prices can be calculated using the below-mentioned formula:
(original price - new price) / original price * 100
(54 - 50) / 54 * 100 = 7.41% decrease.
Step-by-step explanation:
The percent decrease in price expresses the change in price as a percentage of the original price.
To calculate it, subtract the new price from the original price and divide the result by the original price. Multiply that result by 100 to get the percentage decrease.
In this case, the original price was $54 per barrel, and the new price was $50 per barrel, for a 7.41% decrease. This means that the price of oil fell by 7.41% from $54 to $50 per barrel.

Kate spent 15.5% of the money in her pocket on dinner. Her dinner cost $20. How much did he have in her pocket?
Answer:
You can use the proportion of how much money Kate spent on dinner to find out how much money she had in her pocket. The proportion is:
(amount spent on dinner) / (total amount of money in pocket) = (dinner cost) / (100%)
We know that the dinner cost was $20 and that Kate spent 15.5% of her money on dinner. So we can set up the proportion like this:
(x * 0.155) = 20
To find the value of x, we can divide both sides of the equation by 0.155:
x = 20 / 0.155
x = 129
So Kate had $129 in her pocket.

List the angles of WXY in order from least to greatest if WX=9x-7, XY = 12x-1, WY= 3x + 4,
and the perimeter of WXY = 68.
Answer: Hello There.
To solve this problem, we can use the fact that the sum of the interior angles of a triangle is 180 degrees.
First, we know that the perimeter of WXY is 68, so we can set up the following equation:
WX + XY + WY = 68
Then we can substitute in the given values for WX, XY, and WY:
(9x-7) + (12x-1) + (3x+4) = 68
We can then solve for x by adding like terms and setting the equation equal to 0:
24x = 77
x = 3.29
Now that we have the value of x, we can substitute it back into the equations for WX, XY, and WY to find the lengths of each side:
WX = 9x-7 = 9(3.29)-7 = 27.61
XY = 12x-1 = 12(3.29)-1 = 38.48
WY = 3x+4 = 3(3.29)+4 = 13.87
Now we can use the Law of Cosines to find the angles of WXY
cos(A) = (WX^2 + WY^2 - XY^2)/(2WXWY)
cos(B) = (XY^2 + WX^2 - WY^2)/(2XYWX)
cos(C) = (WY^2 + XY^2 - WX^2)/(2WY*XY)
Once we have the cosine of the angles, we can use the inverse cosine function to find the measure of the angles in degrees. Then we can sort the angles from least to greatest.
Please note that this is only one way to solve this problem, and there might be other ways to approach it.
