Answer:
x = 34 degrees
Step-by-step explanation:
there are many rules when it comes to parallel lines but this is called corresponding angles which means if we know these two are parallel lines then x and 34 will be the same therefore x will equal 34
Answer:
34

There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?
Answer:
500 bricks.
Step-by-step explanation:
There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?
To solve e the above question, we have:
20 feet high = 250 bricks
40 feet high = x bricks
Cross Multiply
20 feet × x bricks = 40 feet × 250 bricks
x bricks = 40 feet × 250 bricks/20 feet
x bricks = 500 bricks
Therefore, 500 bricks will be used to build a wall is 40 feet high.

Step-by-step explanation:
need help asap 20 points. thank u in advance
Answer:
$50 and $6
Step-by-step explanation:
(x-6)(250-5x)=0
250x - [tex]5x^{2}[/tex] - 1500 + 30x = 0
-5x^2 + 280x - 1500 = 0
(divide everything by -5)
x^2 -56x + 300 = 0
(factorise)
(x-50)(x-6)=0
x=50, x=6
A projector displays an image on a wall. The area (in square feet) of the projection is represented by x^2-8x+15
a. write a binomial that represents the height of the projection
b. find the perimeter of the projection when the height of the wall is 8 feet
Answer:
a. (x - 5) ftb. 16 ftStep-by-step explanation:
The area given:
x² - 8x + 15a. The height is the factor of the area:
x² - 8x + 15 = x² - 3x - 5x + 15 = x(x - 3) - 5(x - 3) = (x - 3)(x - 5)The width is x - 3, so the height is x - 5
b. The perimeter formula:
P = 2(x - 3 + x - 5) = 2(2x - 8) = 4x - 16The height of the wall is 8 ft:
x = 8The perimeter is:
P = 4*8 - 16 = 32 - 16 = 16 ftExponential form 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1

The captains of the soccer team describe ordering identical T-shirts for the team. Bindi says the total cost is $192. Gina says the cost is 8t, where t is the number of T-Shirts. Which person tells how much each T-shirt costs? How do you know?
Answer:
Both of them.
Step-by-step explanation:
Gina says the cost is 8t, which means you can easily find out the cost of each t-shirt if you know the the total cost too. Bindi says the total cost was 192, which is completely useless on its own, but paired with Gina's info, you can get the answer. Divide 192 by 8, and you get the cost of each t-shirt.
what are the like terms in the expression 8+x^2-4x^3+5x+2x^2?
Answer:
B. x^2x2 and 2x^22x2
Step-by-step explanation:
The expression given is:
8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2
Like terms are terms in which their variables and the power of the variables (exponents) are the same.
While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.
In that case, the like terms in the expression given are x^2x2 and 2x^22x2 .
Note: The question says 8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2 but the option has -4x^2−4x2 .
In case its actually -4x^2−4x2 instead of -4x^3−4x3 , then,
-4x^2−4x2 is also a like term and the answer will be D.

How to represent 3/4 in a number line
Answer:
make it a decimal then with that decimal put it on a number line
Step-by-step explanation:
Answer:
you would get .75 from making it a decimal, so make a decimal number-line from .7 to .8 from exactly between the .8 and .7 remember the .8 will be at the end of the number line and the .7 will be at the start make 10 tick marks and mark it exactly in the middle because it's 5 after the .75
Step-by-step explanation:
start of the numberline .7 .750
end of the numberline .8 wanna see how? look. .800
(zeros after the decimal number dont matter but im showing you that the eight is bigger) I'm trying to show you that .8 is bigger. Obviously the .8 is bigger.

Point (7,12) is rotated 1260° counterclockwise about the origin. What is the X-coordinate of the point after this rotation?
Given:
Point (7,12) is rotated 1260° counterclockwise about the origin.
To find:
The x-coordinate of the point after this rotation.
Solution:
If a point is rotated 360 degrees then its coordinates remains unchanged.
If a point is rotated 180 counterclockwise about the origin degrees, then
[tex](x,y)\to (-x,-y)[/tex]
We know that,
[tex]1260^\circ=1080^\circ+180^\circ[/tex]
[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]
After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.
[tex](7,12)\to (-7,-12)[/tex]
The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.
Therefore, the x-coordinate of the required point is -7.

Karen bought 8 pounds of fruit to make 3 equal-sized fruit salads. What is the weight of each fruit salad? 2 pounds 223 2 2 3 pounds 3 pounds 313 3 1 3 pounds
Answer: 2²/₃ pounds
Step-by-step explanation:
There are 8 pounds of fruit.
These are to be used to make 3 equal sized fruit salad.
The weights of each fruit salad will therefore be:
= Pounds of fruit/ Number of fruit salads
= 8 / 3
= 2²/₃ pounds
What is the output of the function when the input is 10? On the graph plot this point and label its coordinates
Answer:
Output value = 20
Step-by-step explanation:
Graph of any function is made up of two values → Values on x axis and Values along y axis.
x values represent the input values and y values represents the output values.
For every x value there is a y value because of which the data set is called to a function.
In other words, a function can't have two output values for a single input value.
If the input value of function is = 10
Then for x = 10, out value (along y axis) will be = 20
Therefore, Output value of the given function is 20.
Brian bought 215 pounds of strawberries. In the afternoon his brother ate 56 of the strawberries. How many pounds of strawberries did his brother eat?
Hi there!
Step By Step:
We know that 215 pounds are about 215 strawberries since every strawberry are about 1 pound.
Let think about this... 215 pounds are 215 strawberries.
If his brother ate 56 of the strawberries, it means that his brother ate 56 pounds of the strawberry.
We can also think like this... 56/215
Final Result: 56 pound sof strawberries.

To prevent fraying, a binding is attached to the outside of a circular rug whose radius is 3 ft. If the binding costs $1.35 per foot, find the cost of the binding. Use 3.14 for . (Round your answer to the nearest cent.)
$
Answer:
$4.71
Step-by-step explanation:
you would multiply the radius times pi (you would get 6.42 ft) and then divide that by 1.35 (simplifying it to 642 divided by 135 and you would then get 4.706...)which rounds to the answer
