Which angle corresponds to angle F?
A
B
C
D
Answer:
Step-by-step explanation:
Two angles that total 180 degrees are called
Answer:
Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be.
Answer:
They are supplementary angles
Select the correct answer. Factor the expression. A. (7x − 4)(7x − 4) B. (4x − 7)(4x − 7) C. (7x + 4)(7x − 4) D. (4x + 7)(4x − 7)
Answer:
C. (7x + 4)(7x − 4)
Step-by-step explanation:
Given expression:
49x² - 16
Using difference of two squares:
A² - B² = (A + B)(A - B)
49x² - 16 = (7x)² - (4)²
= (7x + 4)(7x - 4)
C. (7x + 4)(7x − 4)
Check:
(7x + 4)(7x − 4)
Open parenthesis
= 49x² - 28x + 28x - 16
= 49x² - 16

Answer:
The answer is B, It's the only one that doesn't equal to Zero
Step-by-step explanation:
Excluded values are also called points of discontinuity. These are the values that make the denominator equal to zero and are not part of the domain

A right cone has radius 5 ft and slant height 9 ft. The radius and slant height are both multiplied by 1/2. Which of the following correctly describes the effect on the surface area?
Answer:
101.07ft^2
Step-by-step explanation:
Given data
radius= 5ft
h= 9ft
When the radius and height are both multiplied by 1/2
radius= 5/2ft = 2.5ft
height= 9/2 ft= 4.5ft
The expression for the surface area of the cone is
A=πr(r+√h^2+r^2)
Substiute
A= 3.142*2.5(2.5√4.5^2+2.5^2)
A= 7.855(2.5√20.25+6.25)
A= 7.855(2.5√26.5)
A= 7.855(2.5*5.147)
A=101.07 ft^2
Hence the surface area is 101.07ft^2
Answer:
The surface area is multiplied by 1/4.

The base of a triangle is 5 units greater than the height, if its area is 18cm2, what is the quadratic equation that models the situation described and is used to find the height of the triangle?
base= 5+h
height= h
area= 1/2bh, so since our area us 18cm^2
therefore 18=1/2*b*h
18*2=(5+h)*h
36=5h+h^2
h^2+5h-36=0 ( for quadratic equation)
h^2+9h-4h-36=0
(h^2+9h)(-4h-36)=0
h(h+9)-4(h+9)=0
(h-4)(h+9)=0
h=4 or h= -9

A map show a town with an area of 3.5 inches.If the map has a scale of 1 inch:4 miles,what is the actual area of the town?
Answer:
The actual area of the town is 14 miles.
Step-by-step explanation:
Since you know that the scale is 1 inch:4 miles and that the map shows a town with an area of 3.5 inches, you can expressed this as follows:
Scale: 1 inch:4 miles
map area: 3.5 inches
If the actual area is x, you can say that:
3.5:x=1:4
This would be:
[tex]\frac{3.5}{x}=\frac{1}{4}[/tex]
Now, you can solve for x:
x=(3.5*4)/1
x=14
According to this, the answer is that the actual area of the town is 14 miles.
You deposit $3000 into an account that pays 4.8% interest, compounded monthly. A) What is the value of the account after 5 years?B) How long will it take for the value of the account to reach $6000?
Answer:
14.4 years (about 14 years 6 months)
Step-by-step explanation:
Given data
Principal= $3000
Rate= 4.8%
A. Time= 5 years
The expression for compound interest is
A=P(1+r)^t
Substitute
A= 3000(1+0.048)^5
A= 3000(1.048)^5
A=3000*1.264
A=$3792
Hence the balance will be $3792
B. Final Amount A = $6000
The expression to find time is given ast
t= ln(A/P) / r
substitute
t= ln(6000/3000)/0.048
t= ln2/0.048
t= 0.6931/0.048
t=14.43
Hence the time is 14.4 years (about 14 years 6 months)approx

Jack's gross weekly pay is $498. He has $52 withheld from each paycheck for federal income
tax. In addition, Social Security, Medicare, state tax of 2.5 percent, and local tax of 1.25
percent are withheld from his paycheck. How much is withheld in Social Security, Medicare,
State, and Local taxes? Finally, what is his net pay?
Answer:
A. 56.78 B. 389.22
Step-by-step explanation:
A.Social security: 498x.062=30.88
medicare: 498x.0145=7.22
state tax: 498x.025=12.45
local tax: 498x.0125=6.23
total of above = 56.78
B. Total taxes above (56.78) + federal withheld (52) = total taxes 108.78
total pay 498 - total taxes 108.78 = 389.22
-5x -10 >30 help Hehehehehe.
Answer:
x<-8
Step-by-step explanation:

(add 10 to both sides)
-5x-10+10>30+10
-5x>40
[tex]\frac{-5x}{-1}[/tex]<[tex]\frac{40}{-1}[/tex]
(dividing through by -1 changes the sign of the inequality from "<" to ">")

Answer:
180ft
Step-by-step explanation:
By using the formula, we do Pi (3) x the radius which is 6² then x by the height, so, we do 3 x 6² x 5. 6² is 36. 3 x 36 = 108. Next, we do 5 x 108. This gives us 540. Now, we have to divide by 3. This makes our answer 180ft.

An artist spent $75 on supplies to create paintings. Each painting the artist created was sold for $25.
Which function can be used to find p, the profit when x paintings are sold?
Answer: 25*x=p
or
75/25=3
3= how many paintings the artist made
Step-by-step explanation:
If you divide 75 by 25, you get 3. Use that 3 to find the profit. Or it could be 25 times x which would get you the amount of p.
