Andrew Filled a measuring cup with 7/8 of a cup of olive oil then he poured 1/2 of a cup of the oil into a bowl. How much oil is left in the measuring cup
Answer:
3/8
Step-by-step explanation:
Andrew filled a measuring cup with 7/8 of olive oil
He poured 1/2 of the oil into a bowl
Therefore the amount of oil that will be left can be calculated as follows
= 7/8 - 1/2
= 3/8
Hence 3/8 oil will be left
Check the box labeled Show Segment Parallel to BC. Notice that DE intersects two sides of triangle ABC creating a smaller triangle, triangle ADE. How is triangle ADE related triangle ABC to ? How do you know?
Answer: Since corresponding angles of parallel lines cut by a transversal are congruent, ADE = ABC and AED = ACB. So, based on the AA criterion for similarity, ABC ~ ADE.
Step-by-step explanation: Sample answer from Edmentum! Hope It helps :)
The triangle ADE is similar to the triangle ABC.
What is a similar triangle?Similar triangles are triangles whose corresponding lengths are not equal to each other, but their corresponding angles are equal.
The relation between triangle ADE and ABC is shown below:It is given that the line segment DE is parallel to BC.
Since it is parallel to each other, we can say that the angles formed on both the line segments are equal to each other since they are corresponding angles. Angle A is common to both the triangles.
Therefore, we can say that the two triangles are similar because all the angles are the same in each triangle.
Therefore, we have found out that the triangle ADE is similar to the triangle ABC.

Find the equation of the linear function represented by the table below in slope-intercept form. x y -1 3 1 1 3 -1 5 -3
Answer:
y = - x + 2Step-by-step explanation:
Points given:
(-1, 3), (1, 1), (3, -1), (5, -3)Slope-intercept form:
y = mx + bFinding the slope using slope formula and the first two points:
m = (1 - 3)/(1 - (-1)) = -2 / 2 = -1Finding y-intercept using the slope and the first point:
3 = (-1)*(-1) + b3 = 1 + bb = 3 - 1b = 2So the equation is:
y = - x + 2y = 4x + 12
What is the x - intercept?
Answer:
The x-intercept is -3
Step-by-step explanation:
So what you need to do is just graph this like any other equation
Start and (0, 12) and make a point
Then the slope is 4 so go up 4 and right 1 and keep doing that.
Then go the opposite direction so down 4 left 1
After that see where the line hits the x-axis, in this case, its (-3, 0)
So the x intercept is -3 or (-3, 0)
Pls mark brainliest because i didn't waste your time lol
Answer: (-3, 0)
Step-by-step explanation: If you want to find the x- intercept for y = 4x + 12, you’ll have to plug y = 0 into the equation and solve the resultint equation 0 = 4x + 12 for x. [0 = 4 x -3 + 12]. Hence, x = -3, so the x - intercept is (-3, 0).

100 % if my grade and giving brainliest if answered correctly please helppp im failing
Answer:
Hope I'm not too late for this...
(look below)
Step-by-step explanation:
For the first part:
1. b = -1, m = 2
The y-intercept (b) is the value of y when x = 0. In this case, we can see that when x = 0, y = -1 so the y-intercept is -1.
The slope was found using the equation slope (m) = (y2-y1) / (x2-x1) and two points. (Note, you can choose any two points, I just chose the first two.)
(5,9) (-2,-5)
slope = (y2-y1) / (x2-x1)
slope = (-5-9) / (-2-5)
slope = -14/-7
slope = 2
I used the same steps as shown above:
2. b = 2, m = -3
For the second part:
1. y = 2x - 1
2.y = -3x + 2
I basically plugged in the values for m and b into the equation, y = mx + b.
Graphs:
The way to graph a line is to plot at least two points and draw a line through them. You can graph it using either the equation or the table. I used the table since it is much easier to find the points that I need.
Below I have included references to what the graph should look like if you need to check your work.
The one in blue is for the equation y = 2x - 1. This should help you get a visual of what the correct graph looks like.
The one in green is for the equation y = -3x + 2.

Answer:
111°
Step-by-step explanation:
The polygon given is a heptagon having 7 sides.
Sum of interior angles of a 7-sided polygon = (n - 2)*180
= (7 - 2)*180
= 5*180 = 900°
Therefore:
126° + 158° + 120° + 125° + 121° + 139° + x° = 900°
Solve for x
789° + x° = 900°
Subtract 789 from each side
x = 900° - 789°
x = 111°

Since the fractions have the same denominator, all we have to do is subtract the numbers in the numerator:
15 - 3 = 12
The difference of the two fractions is [tex]\frac{12}{20}[/tex]. To simplify this answer, divide both the numerator and the denominator by 4:
12/4 = 3
20/4 = 5
The difference in simplified form is [tex]\frac{3}{5}[/tex].

The coldest temperature last December was –18.24 degrees. The difference between this and the highest recorded temperature was 56.24 degrees. What was the highest recorded temperature?
Answer: The highest recorded temperature was 38 degrees.
Step-by-step explanation:
Given: The coldest temperature last December was –18.24 degrees.
Difference between this and the highest recorded temperature=
56.24 degrees
The highest recorded temperature = coldest temperature + difference
= -18.24+56.24 degrees
= 38 degrees
Hence, the highest recorded temperature was 38 degrees.

A dressmaker needs to cut 6-inch pieces of ribbon from rolls of ribbon that are 9 feet in length. How many 6-inch pieces can the dressmaker cut from 15 of these rolls of ribbon? Before you try that problem, answer the question below. How many inches of ribbon does the dressmaker have, in total?
Answer:
Step-by-step explanation:
Answer:
60 pieces
Step-by-step explanation:
What we know:
There are 12 inches in a foot
There are 5 6-feet lengths of ribbon
So, we simply need to multiply.
Since there are 12 inches in a foot, and we only need 6 inches for each one, we can see that she makes 2 pieces for each foot.
Multiply
2*6=12
She makes 12 pieces for each length of ribbon.
Now multiply it by 5
12*5= 60
She can make 60 pieces from 5 of these length of ribbon.
Hope this helps!
Why can you use cross products to solve the proportion StartFraction 18 over 5 EndFraction = StartFraction x over 100 EndFraction for x?
9514 1404 393
Answer:
it is application of the multiplication property of equality
Step-by-step explanation:
You can use "cross products" to solve any proportion. What looks like a "cross product" is just application of the multiplication property of equality. That property says the variable value is unchanged if both sides of the equation are multiplied by the same value.
For your fraction, the "cross product" is what you get when you multiply both sides of the equation by 500.
[tex]\dfrac{18}{5}=\dfrac{x}{100}\qquad\text{given}\\\\\dfrac{18\cdot5\cdot100}{5}=\dfrac{x\cdot5\cdot100}{100}\qquad\text{multiply by $5\cdot100$}\\\\18\cdot100=5\cdot x\qquad\text{cancel common factors; looks like cross product}[/tex]
__
Note that the next step here is to divide by the x-coefficient, the 5 that was in the left-side denominator.
[tex]\dfrac{18\cdot100}{5}=x\qquad\text{divide by 5}[/tex]
Please also note that this is exactly the same result you would get by multiplying the original equation by the original denominator of x.

Two marathon runners run the full distance of the marathon, approximately 26 miles, in 4 hours.
Part A
About how many miles did they run in 1 hour?
Enter the correct answer in the box. Part B
What percent of the full distance have they run in 1 hour?
Enter the correct answer in the box.
Answer:
6.5 miles in 1 hour and they will run 75% of the full distance in 1 hour.
Step-by-step explanation:
The distance covered by two marathon runners = 26 miles
They takes 4 hours
We need to find how many miles did they run in 1 hour
In 4 hour, the distance covered is 26 miles
To find distance covered in 1 hour, divide 26 by 4 such that.
[tex]d=\dfrac{26}{4}\\\\d=6.5\ \text{miles/hour}[/tex]
So, they will cover 6.5 miles in 1 hour.
For percentage,
[tex]\%=\dfrac{26-6.5}{26}\times 100\\\\=75\%[/tex]
So, they will run 75% of the full distance in 1 hour.
