Step-by-step explanation:
17 and 18 please no links
Answer:
Below
Step-by-step explanation:
Since all angles in a triangle add up to 180 degrees, all you need to do to find the 1 missing angle is to subtract the given values from 180.
17) 180 - 25 - 102 = 53
Angle Q = 53 degrees
18) 180 - 46 - 34 = 100
Angle E = 100 degrees
Hope this helps, good luck!

It takes 3/4 of a cup of sugar to make one batch of cookies how many cups of sugar does he need to double the recipe
Answer:
Step-by-step explanation:
3/4 cups → 1 batch
x cups → 2 batches
x = 2(3/4) = 6/4 = 1 1/2 cups
3/4 cups → 1 batch
y cups → 9 batches
y = 9(3/4) = 6 3/4 cups

Solve the equation with logs on both sides of the equation. Please try to be quick
Answer: a=-1
Step-by-step explanation:
Given
[tex]\log_2 (-a+4)=\log _2(3-2a)[/tex]
As the base of both the logarithm is the same. Therefore, the value inside the logarithm is also the same
[tex]\Rightarrow -a+4=3-2a\\\Rightarrow 2a-a=3-4\\\Rightarrow a=-1[/tex]
Thus, the value of a is -1

Thomas has 12 more marbles than twice the number of marbles Andrew has. Andrew has x marbles. Which expression represents how many marbles Thomas has?
Answer:
2x + 12
Step-by-step explanation:
Let
x = number of marbles Andrew has
Number of marbles Thomas has = 2x + 12
The expression which represents number of marbles Thomas has = 2x + 12
If Andrew has 2 marbles, that is, x = 2
Then, 2x + 12 = 2(2) + 12
= 4 + 12 = 16
Thomas = 16 marbles
Find the volume of the cylinder . Round to the nearest tenth. r = 5 cm 5 cm V=[?]cm^ 3
Answer:
V = 392.70 cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
V = 22/7 * 5² * 5
V = 392.70 cm³
Answer: Acellus uses 3.14 for pi, so 5^2*5*3.14 is 392.5
Step-by-step explanation: 392.5
Write the equation of a line that is perpendicular to x = -1 and that passes through the Point (8, -4).
Answer:
y = - 4
Step-by-step explanation:
x = - 1 is the equation of a vertical line parallel to the y- axis
The equation of a line perpendicular to it will therefore be a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (8, - 4 ) with y- coordinate - 4 , then
y = - 4 ← equation of perpendicular line

M&M plain candies have a normally distributed weight with a mean of 0.8565 g and a standard
deviation of 0.0518 g. If 465 M&M plain candies are randomly selected, find the probability that
their mean weight is at least 0.8535 g each.
Answer:
0.89417
Step-by-step explanation:
Using the relation to obtain the Zscore :
Z = (x - mean) ÷ standard deviation / sqrt(n)
x = 0.8535
Mean = 0.8565
Standard deviation = 0.0518
Sample size, n = 465
P(x ≤ 0.8535) = (0.8535 - 0.8565) ÷ 0.0518/sqrt(465)
P(x ≥ 0.8535) = - 0.003 / 0.0024021
P(x ≥ 0.8535) = - 1.249
P(Z ≥ - 1.249) = 0.89417

look at the rectangle and the square. ada says the length of diagonal SQ is two times the length of diagonal OM. is ada correct? justify your answer and show all of your work your work should state the serum you use to find the length of the diagonals.
Answer:
No Ada is not correct
Step-by-Step Explanation:
The length of diagonal SQ is not two times the length of diagonal OM. When you split the rectangle using the diagonal you can make a right triangle and use the Pythagorean Theorem to the rest of it.
This would be the Rectangle:
a^2+b^2=c^2
8^2+16^2=c^2
64+256+c^2
320=c^2
√320
17.8
This would be the Square:
a^2+b^2=c^2
8^2+8^2=c^2
64+64=c^2
128=c^2
√128
11.3
Now when I divide these answers that I came up with I get 1.7 which is not equal to 2 therefore SQ is not two times bigger than OM.
I hope this helped :3

A rectangular roof shingle has a perimeter of 32 inches and an area of 60 square inches. What are the dimensions of the shingle?
Answer:
Length = 6 inches, Width = 10 inches
Step-by-step explanation:
A rectangular roof shingle has a perimeter of 32 inches and an area of 60 square inches. What are the dimensions of the shingle?
Note :
L = Length
W = Width
The perimeter of a rectangle = 2( L + W)
The area of a rectangle = LW.
A rectangular roof shingle has a perimeter of 32 inches and an area of 60 square inches.
32 = 2( L + W)
Divide both sides by 2
16 = L + W.... Equation 1
L = 16 - W
Also:
LW = 60....... Equation 2
Let us substitute 16 - W for L in Equation 2
(16 - W)W = 60
16W - W² = 60
W² - 16W + 60 = 0
W² - 6W - 10W + 60 = 0
W(W - 6) - 10(W - 6) = 0
W - 6 = 0, W = 6 inches
W - 10 = 0, W = 10 inches
Solving for L
W = 10
L = 16 - 10
L = 6 inches
Therefore, the dimensions of the shingle =
Length = 6 inches, Width = 10 inches
