Answer:
the answer is 40.5
Step-by-step explanation:
dont need explanation just my brain
Answer:
40.5 cm²
Step-by-step explanation:
To find the triangles area on the tip of the crayon you do base x height ÷ 2 so 3 x 2 ÷ 2 = 3.
After, multiply 12.5 by 3 then add them both together to get 40.5 cm²

1. The media reported that Olympic gold medalist Michael Phelps regularly consumed at least 8,000 calories per day when he was training for the Olympics. In order to do this, he ate at least three extra-large meals and also consumed a maximum of 2,000 calories worth of special energy drinks each day.
a.Write and graph an inequality to represent the number of calories from energy drinks Michael Phelps drank per day while training
b.Write and graph an inequality to represent the total number of calories Michael Phelps consumed each day.
2. Write a situation about Michael Phelps in which the inequality 3m + 2,000 ≥ 8,000 would represent the situation.
3. To keep from losing weight while training, athletes must not burn more calories than they consume in a day. On one day, Michael Phelps burned 1,000 calories per hour while swimming and an additional 3,000 calories while out of the pool. Write and solve an inequality to estimate the number of hours he swam that day if his daily average caloric intake was at most 9,000 calories.
4. An athlete wants to maintain a net caloric intake of no more than 2,000 calories for the day.
a. Write and solve an inequality to determine how many hours she must train if she burns an average of 750 calories per hour and eats a total of 8,000 calories.
b. Graph the solution to your inequality on a number line. Explain why your answer to part a is a solution to this situation.
c. If she trains 8 hours per day, what is the greatest caloric intake she can have to keep from losing weight? Explain your reasoning.

The probability of rolling two number cubes whose numbers match is 6/36.
What is the probability of rolling at least 1 five?
Answer:
1/6
Step-by-step explanation:
if the chance is 6/36 for the first then the answer would be 1 in 6 to at least get a 5
Based on the probability of the number match, the probability of rolling at least 1 five is 1/6.
What is probability?Probability is the possibility of an event happening or not.
It is also described as the chance or likelihood of an event happening or not.
In a cube, there are six faces numbered 1 to 6
The probability of rolling two number cubes whose numbers match is 6/36.
Then 5 is a number our of the six numbers.
Therefore, the probability of rolling at least 1 five is 6/36 or 1/6.

have a great day bye :)
Answer:
Step one was a mistake.
Step-by-step explanation:
Step one was supposed to be 8/3 = 3c + 15/3. Since he made it multiplied 3 by c, he has to multiply 5/3 by 3 as well.
Rory covers her boat with a square plastic tarp. The tarp has an area of 900 square feet. What is the length of a side of the tarp in feet?
27
30
35
15
Answer:
30 ft
Step-by-step explanation:
Since Rory's plastic tarp is a square, then that means that the side lengths are equal, so the answer must be square root of 900, which is 30!

Answer:
2 units left2 units downreflection across the y-axisStep-by-step explanation:
The letters designating the original figure, RSTU, start at the bottom of the figure and proceed clockwise around it. The letters designating the image, R'S'T'U' start at the bottom and proceed counterclockwise around it. This tells you ...
the figure has been reflected once (CW-CCW order is reversed)the line of reflection is a vertical line (up-down orientation hasn't changed)__
The fill-in for the answer tells you that translation takes place before reflection. To figure out how much translation is needed, you need to know the line of reflection.
Line of ReflectionYou can look at the reflection choices to see where the line of reflection is. We're guessing that the only vertical line choice is the y-axis. (If the line of reflection is x=1, there doesn't need to be any horizontal translation.) If the image is reflected across the y-axis, the point R' moves from (-3, 0) to (3, 0). This is where R' is reflected from.
TranslationThe point R is at (5, 2). To move R from (5, 2) to (3, 0) prior to reflection, the x-coordinate needs to decrease by 2 (from 5 to 3), and the y-coordinate also needs to decrease by 2 (from 3 to 0). That is, the point R must be translated left 2 and down 2 to get it to (3, 0).
__
R'S'T'U' is the image of RSTU after translation 2 left, 2 down, and reflection across the y-axis.
Mr. Ledger buys a box of 24 donuts for a lesson in his math class about circumference.
Write an equation for the number of donuts y that are left at the end of the day when x donuts are used during the lesson.
Last year, Mr. Ledger used 18 donuts during the lesson. This year, he used 22 donuts.
Place points on the graph to show how many donuts are left at the end of last year's lesson and this year's lesson.
Answer:
donuts L that are left at the end of the day when U donuts are being used during the day: y=24-x. You minus x, the # of donuts being used from 24, the total amount of donuts. To get your y.

Find the equation of a line which is parallel to the line with the equation 2x + y = 4 and
which passes through the origin.
Answer:
y = -2x
Step-by-step explanation:
Given
2x + y = 4Passes through the origin (0, 0)Solving
Rewriting the equation
2x + y = 4y = -2x + 4New equation
The slope of the new line is the same (-2) because it is parallelThe y-intercept is (0, 0)⇒ y = mx + b [m = slope, b = y-intercept]
⇒ y = -2x + 0
⇒ y = -2x
Answer:
2x+y=0
Step-by-step explanation:
Given:
[tex]\displaystyle \large{2x+y=4}\\\displaystyle \large{y=-2x+4}[/tex]
To find:
The equation of line that’s parallel and passes through origin point.Parallel Definition:
Both lines have same slope.Slope-Intercept:
[tex]\displaystyle \large{y=mx+b}[/tex]
m = slopeb = y-interceptTherefore, another line is:
[tex]\displaystyle \large{y=-2x+b}[/tex]
Since the line passes through origin point which is (0,0). Substitute x = 0 and y = 0 in the equation:
[tex]\displaystyle \large{0=-2(0)+b}\\\displaystyle \large{b=0}[/tex]
Therefore, the equation is:
[tex]\displaystyle \large{y=-2x}[/tex]
Convert back to standards form:
[tex]\displaystyle \large{2x+y=0}[/tex]
Therefore, another line that is parallel to [tex]\displaystyle \large{2x+y=4}[/tex] is 2x+y=0

A student made two patterns to show multiplication of a declmal by powers of ten. The equations shown for both patterns are incorrect. Pattern A 3.675 • 10 = 3.6750 3.675 - 100 = 3.67500 3.675. 1.000 = 3.675000 Pattern B 3.675.0.1 = 3.0675 3.675 -0.01 = 3.00675 3.675 -0.001 = 3.000675 explain why the equations in each of the patterns are false. include in your explanation the values that should appear on the right side of each equation in both patterns to make the equations true.
Answer:
Step-by-step explanation:
The correct solving of the decimal shows that 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
How to solve the decimals?
From the information given, it should be noted the students calculations are incorrect. Therefore, 3.675 ×10 = 3.6750, 3.675 × 100 = 3.67500 and 3.675 × 1,000 = 3.675000 are incorrect.
In this case, when multiply by raise to power 10, it's important to shift the decimal based on the number being raised to power.
Therefore, 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
