Answer:
Susan has more books than Michael.
Step-by-step explanation:
If Susan has 50% more books and Michael has 40 books, that means Susan has 1.5 times 40 = 60
40 + 8 = 48
60 is more than 48, so Susan has more books than Michael

Solve the equation: 7 equals p over 5
Answer:
p = 35
Step-by-step explanation:
7 = p/5
Multiply both sides by 5.
35 = p
p = 35
-5(-2x + 5) - 5 < - 6 - 4x

=============================================
Explanation:
We'll need the tangent rule
tan(angle) = opposite/adjacent
tan(R) = TH/HR
tan(30) = TH/54
sqrt(3)/3 = TH/54 ... use the unit circle
54*sqrt(3)/3 = TH .... multiply both sides by 54
(54/3)*sqrt(3) = TH
18*sqrt(3) = TH
TH = 18*sqrt(3) which points to choice A as the final answer
----------------------
An alternative method:
Triangle THR is a 30-60-90 triangle.
Let x be the measure of side TH. This side is opposite the smallest angle R = 30, so we consider this the short leg.
The hypotenuse is twice as long as x, so TR = 2x. This only applies to 30-60-90 triangles.
Now use the pythagorean theorem
a^2 + b^2 = c^2
(TH)^2 + (HR)^2 = (TR)^2
(x)^2 + (54)^2 = (2x)^2
x^2 + 2916 = 4x^2
2916 = 4x^2 - x^2
3x^2 = 2916
x^2 = 2916/3
x^2 = 972
x = sqrt(972)
x = sqrt(324*3)
x = sqrt(324)*sqrt(3)
x = 18*sqrt(3) which is the length of TH.
A slightly similar idea is to use the fact that if y is the long leg and x is the short leg, then y = x*sqrt(3). Plug in y = 54 and isolate x and you should get x = 18*sqrt(3). Again, this trick only works for 30-60-90 triangles.
Angle C and angle D are complementary. The measure of angle C is (2x)° and the measure of angle D is (3x)°. Determine the measure of the two angles.
Answer:
c=36 degrees
d=54 degrees
What is the slope of the line described by the data in the table below?
Х
-4
0
4
8
y
3
8
13
18
Given:
The table of values is:
x y
-4 3
0 8
4 13
8 18
To find:
The slope of the line that described by the data in the table.
Solution:
Consider any two points from the given table.
Let the two points are (0,8) and (4,13). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{13-8}{4-0}[/tex]
[tex]m=\dfrac{5}{4}[/tex]
[tex]m=1.25[/tex]
Therefore, the slope of the line described by the data in the table is 1.25.
The spinner shown is divided into equal sections that each contain one number, so that the probability of spinning each number on the spinner is the same. However, there are two red sections, and therefore there are a total of two numbers (1 and 3) that appear in red sections, while each other color appears in only one section.
A spinner with 6 equal-sized sections labeled 1 through 6. Sections 1 and 3 are red. Section 2 is blue. Section 4 is orange. Section 5 is purple. Section 6 is green.

aundreys mother has decided to start a college savings account for him. aundrey is about to start kindergarten, and she decides to deposit $1000 in to an account with a 1.3% annual interest rate. How much will be in the account when aundrey starts 4th grade (4 years later) if she makes no deposits or withdrawals and the interest is compounded annually?
a) $27,984.10
b) $1,630.47
c) $1,053.02

Answer:
7.D) 107°
8. A) 123°
Step-by-step explanation:
To find the correct measurement of the angel the sum of the interior angels needs to equal 360°. Angels where the lines intersect with the circle would be both 90°. ( If that makes sense.)
90°+90°=180
180°+73°= 253°
360°-253°= 107°
The same for the second one. (those two angles would also be 90° each.)
90°+90°=180°
180°+57°=237°
360°-237°=123°
I need help please what’s the answer?
Answer:
you equate 7x -2 with 4x+4

Find the area of the shaded part of the triangle below. Round to the nearest tenth if needed.
Answer:
212.5
Step-by-step explanation:
For triangles, A = (bh)/2
You can do 15+25 to find the base, which is 40. From here do 17*40/2. You get 340. However, you need to remove the right triangle on the left side.
Again do 17*15/2, which you get 127.5.
From here subtract 127.5 from 340 and get 212.5

Answer:
x=37
Step-by-step explanation:
a triangle is equal to 180°. so if you already have 50+56 then you have 74° left for 2x. and 74/2=37
Answer:
x=37 because 56+50=106 180-106=74 74÷2=37

Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
Adjacent angles. x = 55
Step-by-step explanation:
Adjacent angles are angles that are right next to each other, sharing one side.
Since that is a right angle (90º):
X + 35 = 90
X + (35-35) = 90 - 35
X = 55
Hope this helps! Have a great day!
Answer:
Adjacent, X= 55
Step-by-step explanation:
90-35= 55
log x - log 6 = 2 log 4
log(x) - log(6) = 2 log(4)
Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):
log(x / 6) = 2 log(4)
Rewrite the right side, using the property n log(a) = log(aⁿ ):
log(x / 6) = log(4²)
log(x / 6) = log(16)
Cancel the logarithms (i.e. take the exponential of both sides):
exp(log(x / 6)) = exp(log(16))
x / 6 = 16
Solve for x :
x = 6 × 16
x = 96
