Answer:
160 pieces of gum in 20 days.
Step-by-step explanation:
First we have to find the number of gum she chewed in a day. To do this divide 112 and 14. We got 8. Then multiply the number of gum she chewed in a day (8) by the number of days (20).
8 x 20 = 160
She chewed 160 pieces of gum in 20 days.

Answer:
X= 42 degrees
Step-by-step explanation:
When combining 3x+12 and x, this results in a 180 degree angle to be formed. Therefore create the equation 3x+12+x=180 to get the value of X.
3x+12+x=180
4x+12=180

Answer:
D.) 119º
Step-by-step explanation:
All angles in a triangle have to add up to 180º. Add 87º and 32º to get 119º, then subtract from 180º to get 61º. Angle C is 61º. Since it's also supplementary to 1, subtract 61º from 180º. 1 is 119º.
Answer:
D) 119°
C) The two angles are supplementary.
Step-by-step explanation:
First problem:
<1 is an exterior angle of the triangle.
<A and <B are interior angles of the triangle far from <1.
For <1, angles A and B are called remote interior angles.
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.
m<1 = m<A + m<B
m<1 = 87° + 32°
m<1 = 119°
Answer: D) 119°
Second problem:
AB is a line. The diagonal line intersects line AB forming 4 angles, a, b, c, and d. Angles c and d are next to each other, called adjacent angles, and have a common side, and the other two sides lie on line AB. That makes angles c and d a "linear pair." Two angles in a linear pair have measures that add to 180°, so angles c and d are supplementary angles.
Answer: C) The two angles are supplementary.

Help I don’t get it..
Answer:
Step-by-step explanation:
the shape looks like a cube.. and maybe they say something about that outside of the picture, even but assuming that it is a cube, we know all the sides are the same.
we also know that the area of one side of the cube is 3 [tex]\frac{1}{4}[/tex]
so multiply that
W x L = area
3 [tex]\frac{1}{4}[/tex] * 3 [tex]\frac{1}{4}[/tex] = area
10 [tex]\frac{9}{16}[/tex] = area
10.5625 = area
those two answer above are the same .. just one is in fractions and one is in decimals
there are 6 sides on a cube, so multiply the above answer by 6
6* answer = 63.375
63 [tex]\frac{3}{8}[/tex] ( this is your answer)
both of those are also identical , but look different for the reasons I mentioned above
use which ever from seems better to you. :)

Three squares each have sides of length 6 units and overlap each other as shown below. The points where the sides cross are midpoints. Find the area of the gray figure in square units.
Answer:
90
Step-by-step explanation:
Partition the figure by extending the sides of the ``middle'' square as shown at the right. Each original square contains four $3 \times 3$ small squares. The shaded figure consists of ten $3 \times 3$ squares, so its area is $10 \times 9 = \boxed{90\text{ square
units}}$.
In this exercise we have to use the knowledge of areas to calculate the area of the square in gray, so we have that:
[tex]A=90[/tex]
First it is informed that one side of the square is 6, so every square has exactly:
[tex]l^2=6^2=36[/tex]
Adding that we have 3 squares with the same value of sides:
[tex]36*3=108[/tex]
However, there are areas that are being calculated twice in the central square, these areas are smaller squares that have side values equal to 3, so:
[tex]l^2=3^2=9\\9*2=18\\108-18=90[/tex]

If 20 articles cost ? 90, then the cost of 9 articles is ?
A. 45
B 4.50
C.40.50
D. 42
Answer:
C. $40.50
Step-by-step explanation:
OK so, If 20 articles cost ? 90, then the cost of 9 articles is ?
First you need to find out how much is 1 article.. Divide 90 by 20 you get, $4.5. now multiply 4.5 by 9. Which you get... 40.5. In other words it can also be written as, 40.50.

If you had a right triangle with legs measuring 40 yards and 100 yards long,
what would be the length of the hypotenuse? Round your answer to the
nearest yard if necessary. *
70 yd
92 yd
108 yd
146 yd
9514 1404 393
Answer:
(c) 108 yd
Step-by-step explanation:
For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...
c² = a² +b²
Solving for c, we have ...
c = √(a² +b²)
c = √(40² +100²) = √(1600 +10000) = √11600
c ≈ 107.70 . . . . yards
The length of the hypotenuse is about 108 yards.
Joy recorded the distances she walked each day for six days. How far did she walk in 6 days? Enter your answer as a mixed number in simplest form.
Answer:
[tex]2\frac{1}{6}[/tex]
Step-by-step explanation:
The question is not complete, but I would show how to solve a similar question.
Joy recorded the distances she walked each day for five days. How far did she walk in 5 days?
Solution:
We can see that Joy distance is recorded in the dot plot. From the dot plot, we can see that she walked 1/3 miles each day for three days, 1/2 miles for one day and 2/3 miles for one day. Therefore, to get the total distance walked, we just have to sum the individual distance that she walked each day. Hence the total distance is given as:
[tex]Total \ distance=\frac{1}{3} +\frac{1}{3} +\frac{1}{3}+ \frac{1}{2}+ \frac{2}{3} =\frac{13}{6}=2\frac{1}{6}[/tex]
A shipping container has a volume of 48 cubic meters. What could be the dimensions (length, width, height) of the container if none of the dimensions are 1 m? Explain how you found the dimensions.
Answer:
6m * 4m * 2m
Step-by-step explanation:
Given that :
Cubic volume = 48 m³
Possible dimension if none of the dimensions is 1 m
Volumetric Dimension = (length * width * height)
The product of the three dimensions must give 48m³
Constraint : none of the dimensions has a volume of 1 m.
Hence, possible dimension :
6m * 4m * 2m = 48m²
Hence, one possible dimension is :
6m * 4m * 2m

C)
BC = 19; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Answer:
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Step-by-step explanation:
15²-12² = 9²
BC = 9
sin B = 12/15 = 0.8
∠B = 53.1°
The solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.
The triangle ABC is a right triangle. The new path is in front of the right angle, therefore it is the hypotenuse. To find the length of the hypotenuse we use the Pythagorean theorem:
H² = P² + B²
The length BC will be calculated as below:-
15²-12² = 9²
BC = 9
The angle B will be calculated as below:-
sin B = 12/15 = 0.8
∠B = 53.1°
Therefore, the solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.

Which proportion can be used to find the arc length, s, in units?
Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s = [tex]\frac{150}{360}(2\pi )(42)[/tex]
[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]
[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]
Therefore, Option B will be the answer.

Brett has a $30 online gift voucher. He plans to buy as many books as he can. The cost of each book is $4. There is also a single shipping charge of $2. How many books can he afford without spending more than his gift voucher amount?
its an inequality eqution, i already know he can spend 30 or less on the boook
answer:
30 > 4x + 2 and 6 books
step-by-step explanation:
read the question and set up the inequalitylet x = number of books he can afford30 > 4x + 2
30 would be on one side since that's the most he can spend4x because each book is $4+ 2 because there is a charge of $230 > 4x + 2
28 > 4x
7 > x
he can afford 6 booksit cannot be 7 because if he does buy 7 books, it would cost more than $30a boat travels at a rate of 25 miles, m, per hour, h. which equation represents this scenario?

Consider this expression. x-4/2(x+4)
Answer:
Option A
Step-by-step explanation:
We will simplify the expressions given in the options first,
x² - 16 = (x - 4)(x + 4)
2x + 8 = 2(x + 4)
x² + 8x + 16 = (x + 4)²
Option A
[tex]\frac{x^2-16}{2x+8}[/tex] × [tex]\frac{x+4}{x^2+8x+16}[/tex]
= [tex]\frac{(x+4)(x-4)}{2(x+4)}\times \frac{(x+4)}{(x+4)^2}[/tex]
= [tex]\frac{x-4}{2(x+4)}[/tex]
Option B
[tex]\frac{2x+8}{x^2-16}[/tex] ÷ [tex]\frac{x^2+8x+16}{x+4}[/tex]
= [tex]\frac{2(x+4)}{(x+4)(x-4)}[/tex] ÷ [tex]\frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{2}{(x-4)}\times \frac{1}{(x+4)}[/tex]
= [tex]\frac{2}{x^2-16}[/tex]
Option C
[tex]\frac{x^2-16}{2x+8}[/tex] ÷ [tex]\frac{x+4}{x^{2}+4x+16}[/tex]
= [tex]\frac{(x-4)(x+4)}{2(x+4)}\times \frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{(x-4)(x+4)}{2}[/tex]
Option D
[tex]\frac{2x+8}{x^2-16}\times \frac{x^2+8x+16}{x+4}[/tex]
= [tex]\frac{2(x+4)}{(x-4)(x+4)}\times \frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{2(x+4)}{(x-4)}[/tex]
