Find the value of x in the following figure.
Answer:
x = 8
Step-by-step explanation:
180-(89+57)= 180-146 = 34
(5x -6) = 34
5x = 34 + 6
5x = 40
x = 40 ÷ 5
x = 8

A. 5 square root 2/2
B 5
C 10
D 10 square root 2
Answer:
The answer is C
Step-by-step explanation:
That side with the 5 is equal to 7.071067812.... (irrational number)
To get x you need to use the equation a^2 + b^2 = c^2
A^2 and B^2 will both be the same thing. The red line indicates they are the exact same length.
7.071037812.... ^2 is 50
Now your equation would be 50+50= c^2 (which is the same as x^2)
100= c^2 is simplified by finding the square root of 100.
Your answer is 10 for side X because the square root of 100 is 10.
This problem was solved using the Pythagorean Theorem.
The hypotenuse x of the right triangle is (c) 10
Finding the hypotenuse, x of the right triangleFrom the question, we have the following parameters that can be used in our computation:
The right triangle
Where, we have
Leg a = 5√2
Leg b = 5√2
The hypotenuse of the right triangle can be calculated using the following Pythagoras theorem
h² = a² + b²
Using the above as a guide, we have the following:
x² = (5√2)² + (5√2)²
Evaluate
x² = 100
Take the square roots
x = 10
Hence, the hypotenuse of the right triangle is (c) 10

. Chris read 25 books in 135 days. At this rate, in how many days will he read another 5 books? Another 10 books?
Answer:
5 books - 27 days
10 - 54 days
15 books - 81 days
Step-by-step explanation:
First, you need to find how many days it takes to read one book, to do this, simply divide 135 by 25 (135/5=5.4). Then, you multiply that number by the amount of books it wants to know how long it would take him to read (5 and 15 since it asks "another 10". It could also be 54 if it was asking how many for 10 books not including the 5 he would have read). 5*5.4=27, 10*5.4=54, and 15*5.4=81.
An isosceles triangle includes two 72°
angles. Which equation could be used to
find the measure of the third angle?
A X + 72 = 180
B X = 180 - 72
C 72-X= 180
D 180 - 2(72) = X
I don't understand the options but I will explain it to u!
Step-by-step explanation:
An Isosceles triangle has two equal sides that means , In this question it is given that there are two 72°angles so,
72+72+x =180
(Transpose)
x = 180-(72+72)
x = 180-(144)
Therefore, x= 36
In an isosceles triangle, two sides are equal and their opposite angles are also equal. Then the correct option is D.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
An isosceles triangle includes two 72° angles.
In an isosceles triangle, two sides are equal and their opposite angles are also equal.
And the sum of the angles of the triangle is 180°.
Let the third angle be x. Then we have
72° + 72° + x = 180°
180° - 2(72°) = x
Thus, the correct option is D.

Jen weighs 100 pounds, Jack weighs 120 pounds, and Billy weighs 80 pounds. What is their average weight?
Answer:
100 pounds
Step-by-step explanation:
To find their average weight, add all of their weights together then divide it by 3
(100 + 120 + 80) / 3
300 / 3
= 100
So, their average weight is 100 pounds

I need help PLEASE !!!! Write a cosine function that has an amplitude of 2, a midline of 4 and a period of 4.
Answer:
[tex]\mathbf{y = 2cos ( \dfrac{\pi}{2}(x - 0) + 4}[/tex]
Step-by-step explanation:
The standardized cosine function is ;
[tex]\mathbf{y = Acos (Bx + C) +D}[/tex]
Amplitude |A| = 2
Period [tex]\dfrac{2 \pi}{B }= 4[/tex]
2π = 4B
[tex]B = \dfrac{2 \pi}{4}[/tex]
[tex]B = \dfrac{\pi}{2}[/tex]
Midline y = 4; D = 4
Phase shift; since no phase shift is given; then C = 0
The cosine function: [tex]\mathbf{y = 2cos ( \dfrac{\pi}{2}(x - 0) + 4}[/tex]

============================================================
Work Shown:
Convert each fraction or mixed number into its equivalent decimal form. Use a calculator or long division.
1 & 3/5 = 1 + 3/5 = 1+0.6 = 1.68/5 = 1.61 & 3/4 = 1 + 3/4 = 1 + 0.75 = 1.751 & 3/8 = 1 + 3/8 = 1 + 0.375 = 1.375The decimal value 1.75 is larger than 1.6, so this shows that 1 & 3/4 is larger than 1 & 3/5
The hotdog stand at a baseball game sells hotdogs for $3.50 each. The amount, D dollars, Mr. Moore paid for the hotdogs is directly proportional to the number of hotdogs, H, he buys. Identify the constant of proportionality and write a direc
Answer:
D α H
k = D/H
k = 3.50
Step-by-step explanation:
Amount paid, D is directly proportional to the number of hotdogs, H
D = $3.50 per hot dog
D = $3.50 is directly proportional to 1 hotdog
Hence,
D α H
D = kH
k = proportionality constant
H = 1
3.50 = k
k = 3.50
k = D/H

All 8 angles measure 135°
Step-by-step explanation:
(n-2)·180 = (8-2)·180 = 1,080°; this is the total of all interior angles
each angle is equal so we can divide 1080 by 8 and find that each angle measures 135°
to solve for 'x':
16x + 23 = 135
16x = 112
x = 112/16
x = 7
check: 16(7) + 23 = 135
112 + 23 = 135
135 = 135
Mrs. Smith is making christmas baskets and wants to evenly divide the 36 ornaments and 24 candy canes so that each basket has the greatest number of
ornaments and candy canes without any left over. When you make the greatest # of baskets, how many ornaments will be in each basket?
A.2
B.3
C.6
D.12
Answer:
C.
Step-by-step explanation:
It is c because 6 can go into both of those numbers when multiplying
Answer:
B. 3
Step-by-step explanation:
We are looking for the greatest number of baskets. The greatest number of baskets is the greatest number that divides evenly into both 36 and 24.
We need to find the greatest common factor of 36 and 24 to find the greatest number of baskets.
36 = 2^2 * 3^2
24 = 2^3 * 3
GCF = 2^2 * 3 = 4 * 3 = 12
The number of baskets is 12.
Now we need to find the number of ornaments that will go in each basket.
36 ornaments / 12 baskets = 3 ornaments/basket
