Answer:
[tex]5820[/tex] square inches
Step-by-step explanation:
For the rectangular prism in the middle:
[tex]24*30=720*2=1140[/tex]
[tex]10*30=300*2=600[/tex]
[tex]1140+600=1740[/tex]
For the left triangular prism:
[tex]10*24=240[/tex]
[tex]26*30=780[/tex]
[tex]24*30=720[/tex]
[tex]10*30=300[/tex]
[tex]240+780+720+300=2040[/tex]
For the other right triangular prism, it's the same.
Let's add now to find the surface for the whole ramp.

Answer:
x = 26
Step-by-step explanation:
x+64 is a right angle
x+64 = 90
Subtract 64 from each side
x = 90-64
x = 26
Answer:
x = 26°.
Step-by-step explanation:
This is a complementary angle. Complementary angles are two angles that have a sum of 90°.

If mAD = (17x + 2)°, mAC = (7x - 10°), and m∠ABC = (4x + 15)°, find m∠ABC
Please help
Answer:
m<ABC = 51degrees
Step-by-step explanation:
The angle at the vertex is half the difference of the angles at the intercepted arcs. Hence;
m<B = 1/2 (arcAD - arcAC)
<ABC = 1/2(17x + 2 -(7x - 10°))
4x + 15 = 1/2(17x-7x+2+10)
2(4x+15) = 10x+12
8x + 30 = 10x+12
8x-10x = 12-30
-2x = -18
x = 18/2
x = 9
Get m<ABC
m<ABC = 4x + 15
m<ABC = 4(9) + 15
m<ABC = 36 + 15
m<ABC = 51degrees
The measure of angle ∠ABC = 51 degree.
Since we know that,
For a circle,
The angle at the vertex is half the difference of the angles at the intercepted arcs.
Therefore,
m∠ABD = 1/2 (arcAD - arcAC)
⇒ ∠ABC = (1/2)(17x + 2 -(7x - 10°))
⇒ 4x + 15 = (1/2)(17x-7x+2+10)
⇒2(4x+15) = 10x+12
⇒ 8x + 30 = 10x+12
⇒ 8x-10x = 12-30
⇒ -2x = -18
⇒ x = 18/2
⇒ x = 9
Get m∠ABC
⇒ m∠ABC = 4x + 15
⇒ m∠ABC = 4(9) + 15
⇒ m∠ABC = 36 + 15
⇒ m∠ABC = 51 degree

At Mathville Middle School, there were 50 students and 50 lockers. Each year for Pi Day (March 14), the students lined up in alphabetical order and performed the following strange ritual. The first student opened every locker. The second student went to every second locker and closed it. The third student went to every third locker and changed it (i.e. if the locker was open, the student closed it; if the locker was closed, the student opened it). In a similar manner, the fourth, fifth, sixth, . . . student changed every fourth, fifth, sixth, . . . locker. After all 50 students had passed by the lockers, which lockers were left open?
PLZZZZ help me T^T
Step-by-step explanation:
This problem is a bit tedious to work out all at once. The first student opens every locker so lockers 1 to 50 are open.
The second student closes every two lockers so every even locker is closed while every odd locker is open. This will repeat over and over and will take too long.
An alternative for this would be checking the factors of each number. For example, 4 has three unique factors, which are 1, 2 and 4. The number of unique factors determine whether the locker is open or closed. In this case, locker 4 will be open after all 50 students finished. Student 1 opens locker 4, student 2 closes locker 4, student 3 doesn't change locker 4 and student 4 opens locker 4. However, students 5 to 50 will never change the locker.

Find the distance between each pair points
Lisa is building a garden in her backyard in the shape of a right triangle and wants to put a fence around it to keep her dog out.
The longest side of the garden is 20 ft and one of the shorter sides is 9 ft. How long does the 3rd piece of the fence have to be?
Round this value however you need to. The exact length is sqrt(319)
In other words, sqrt(319) = 17.8606
=======================================================
Work Shown:
a = 9 is one of the legsb = unknown is the other legc = 20 is the hypotenuse, aka longest sideApply the pythagorean theorem to solve for b.
a^2+b^2 = c^2
9^2 + b^2 = 20^2
81 + b^2 = 400
b^2 = 400-81
b^2 = 319
b = sqrt(319)
b = 17.8606 which is approximate
I'm going with the approximate value it makes more sense to do so in this case. Saying "the length is sqrt(319)" to someone not familiar with math, would probably not convey just how long the third side must be. Round the value in bold however you need to.
Solve for P.
-1 + 14 p = -435
Answer:
P = -31
Step-by-step explanation:
-1 + 14p = -435
Remove the -1 by adding it from both sides.
14p = -434
Remove the 14 by dividing it from both sides.
p = -434/14
p = -31
Answer:
-31
Step-by-step explanation:
-1+14p=-435
14p=-435-(-1)
14p=-435+1
14p=-434
p=-434/14
p=-31

Answer:
a) There are 4 terms.
b) 2 of them are negative
explanation:
Let's simplify step-by-step.

=−3x^2+2y^2+5xy+−2y+5x^2+−3y^2
Combine Like Terms:
=−3x^2+2y^2+5xy+−2y+5x^2+−3y^2
=(−3x2+5x^2)+(5xy)+(2y^2+−3y^2)+(−2y)
=2x^2+5xy+−y^2+−2y
Answer:
=2x^2+5xy−y^2−2y
Answer:
Step-by-step explanation:
A. There are 6 terms. Even if there is a variable onto the coefficient, it wouldn't be 2 terms but only 1, in this case, there are 6 terms.
B. If I simplify the number of negative terms, there would be 2 terms.-3x^2,-2y, and -3y^2 are all negative terms in this equation. I can't combine all because one has x as a variable and the other 2 has y. If I simplify both of the negative terms (-2, -3y^2) Ill get -5y^2. -2-3= -5 and just add my other values y and 2 square, and in that case, my final 2 negative terms are -3x^2 and -5y^2

The radius of a sphere is 12 units. Find the volume of the sphere. Write your answer in terms of pi.
Answer:
V = 2304π units³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( where r is the radius ) , then
V = [tex]\frac{4}{3}[/tex]π × 12³
= [tex]\frac{4}{3}[/tex] π × 1728
= 4π × 576
= 2304π units³

Step-by-step explanation:
everything can be found in the picture
The nth term of an arithmetic sequence is expressed as Tn = a +(n - 1)d. The 157th term of the sequence is 2180
Arithmetic sequenceThe nth term of an arithmetic sequence is expressed as:
Tn = a +(n - 1)d
where
a is the first termd is the common differencen is the number of termsIf -4 is the first term and 10 is the third term, then;
a = -4
a + d = 10
d = 10 - (-4)
d = 14
Determine the 157th term
T157 = -4 + (157 - 1)(14)
T157 = -4 + (156*14)
T157 = 2180
Hence the 157th term of the sequence is 2180

If two angles are both vertical and supplementary, can we determine the angles? Is it possible to be both vertical and complementary? If so, can you determine the angles? Explain how you know ASAP
Answer:
Two angles can be vertical and supplementary only if they add up to 90 degrees because there perpendicular.
Step-by-step explanation:
Answer:
90 + 90 = 180, 45 + 45 = 90
Step-by-step explanation:
Supplementary angles add up to 180 and to be vertical angles they need to be equal to each other so 2x = 180
x = 90
Hence both angles will be equal to 90
Complementary angles add up to 90 and as previously stated, to be vertical angles they need to be equal to each other so 2x = 90
x = 45
Hence both angles equal to 45
