Answer:
66.9375
Step-by-step explanation:
from what you told me 4cm=21km
if you divide 21 by four, you get how many km is one cm. which is 5.25km
15 divided by 4 = 3.75
what we know is that 4 can go into 15 three whole times. so.. 21x3=63
now what we need to figure out is that .75
so, 75 is three quarters, so i divided 5.25 divided by 4 to get how much one quarter of a cm is in km. then i multipled that by three, giving me: 3.9375
63+3.9375= 66.9375
but you might have to round this i dont know if you do or not so thats the answer im giving

Select all of the expressions that are equivalent to 16 5/2
Answer:
Step-by-step explanation:
C and E are corre6
The expressions that are equivalent to 16^(5/2) is 16^(5/2) is 4^(5), √16^(5), 16^(2 + 1/2), 16^(2) 6^(1/2).
What is an exponent?An exponent is a number or letter written above and to the right of a mathematical expression called the base. The exponent of a number says how many times to use that number in a multiplication.
Now the given expression is,
16^(5/2)
Since 4^2 = 16
Therefore we can write,
16^(5/2) = (4^2)^(5/2)
Using the exponent property,
a^b^(c) = a^(bc)
⇒ (4^2)^(5/2) = 4^{2*(5/2)}
⇒ (4^2)^(5/2) = 4^(5)
Thus,
16^(5/2) = 4^(5)
Now, Using the exponent property,
{a^(b)}^(c) = a^(bc)
Also, 16^(5/2) = 16^{5(1/2)}
⇒ 16^(5/2) = {16^(1/2)}^5
∵ 16^(1/2) = √16
⇒ 16^(5/2) = √16^(5)
Now, Using the exponent property,
a^(b)^(c) = a^{(b)(c)}
Also, 16^(5/2) = 16^(2 + 1/2)
Using the exponent property,
a^(b).a^(c) = a^{(b + c)}
16^(2 + 1/2) = 16^(2) 6^(1/2)
⇒ 16^(5/2) = 16^(2) 6^(1/2)
The expressions that are equivalent to 16^(5/2) is 4^(5), √16^(5), 16^(2 + 1/2), 16^(2) 6^(1/2).

A rectangle has a length of 80 cm and a width of 50 cm. The rectangle is dilated by a scale factor of 3.5 to create a new rectangle. What is the area in square centimeters of the dilated rectangle?
Answer:it’s 4,000
Step-by-step explanation:
The area in square centimeters of the dilated rectangle will be A[d] = 49000 square centimeters.
What is scale factor? How it is used in Dilating sides?
Scale factor tells us by how much one quantity is greater than the other. It is denoted by [K]. Mathematically -
K = a/b.
Rewriting, we get -
a = Kb
If a side length [a] of any 2 - D figure is dilated by a scale factor of [k], then the length of new side will be [Ka]
Given is a rectangle has a length of 80 cm and a width of 50 cm. The rectangle is dilated by a scale factor of 3.5 to create a new rectangle.
Now, after dilation the new dimensions will be -
Length = 3.5 x 80 = 280 cm
Width = 3.5 x 50 = 175 cm
The area in square centimeters of the dilated rectangle will be -
A[d] = 280 x 175 = 49000 square centimeters
Therefore, the area in square centimeters of the dilated rectangle will be A[d] = 49000 square centimeters

A car traveling at 25 m/s starts to decelerate steadily. It comes to a complete stop in 5.5 seconds. What is the car’s acceleration?
Answer:
4.5 m/s
Step-by-step explanation:
acceleration is the change in velocity divided by time. so, 25 m/s going to 0 m/s (stop), which is 25, divided by 5.5 seconds is 4.5 m/s

In Minnesota, the state sales tax rate is 6.875%. The price tag on an HDTV gives
the price as $1560, plus a $100 rebate.. What is the total cost for the TV, including
sales tax and rebate in Minnesota?
Answer:
1560.38
Step-by-step explanation:
As far as I know, a sales tax is never calculated until money changes hands. So the rebate is the first amount to take place.
1560 - 100 = 1460
Now if the purchaser agrees to this amount and does anything to pay partially or in full, the tax is added.
Total Cost = 1460 * (1.06875)
Total Cost = 1560.38
Edit
You have to be very careful when you use a term like rebate. Rebate is a very special kind of discount. Your purchase has to qualify for a rebate. Apparently this one does. If you are willing to spend 1560 on something, the merchant selling the product offers you a rebate to help you decide.
If the TV cost is 1200 you may not get the rebate.

Terrell loves to listen to music, so he buys a subscription to a music-streaming service. He pays $4.99 each month. How much does the streaming service cost per year?
Answer:
[tex]Yearly = \$59.88[/tex]
Step-by-step explanation:
Given
[tex]Monthly = \$4.99[/tex]
Required
Determine the yearly cost
To do this, we multiply the monthly subscription by 12
[tex]Yearly = Monthly * 12[/tex]
[tex]Yearly = \$4.99 * 12[/tex]
[tex]Yearly = \$59.88[/tex]
Hence, the yearly servics cost is $59.88

Step-by-step explanation:
2+6x= -10 + 11(x + 4)
2+ 6x = -10 + 11x + 11(4)
2 + 6x = -10 + 11x + 44
2+ 6x = 11x + 34
6x - 11x = 34 - 2
-5x = 32
x= - 32/5
Answer:
Step-by-step explanation:
1) multiplication- 2+6x=-10+11x+44
2)addition or subtraction- 2+6x=11x+34
3)isolate the variable- -5x=32
4)divide 32 by 5= x=6.4 or 32/5
-5x + y = 35 and 3x + 2y = -21 How would I solve by substitution?
Answer:
x= -7
y=0
Step-by-step explanation:
you want to get one variable alone and substitute it into the other equation
in this case, get the y in -5x+y=35 alone
y=5x+35
now substitute this into 3x+2y= -21
3x+2(5x+35)= -21
3x+10x+70= -21
13x=-91
x= -7
now substitute x into one of the equations
3(-7)+2y= -21
-21+2y= -21
2y=0
y=0
if a * b + 5 *a + 3 * b + 15= 24 and a+ 3 =6 then what is the value of a+b
Answer:
a +b = 2
Step-by-step explanation:
a +3 = 6
a = 6 -3
a = 3
Plugin a =3 in the equation,
a*b +5*a +3*b + 15 = 24
3b + 5*3 + 3b + 15 = 24
3b + 15 + 3b + 15 = 24 {combine like terms}
3b + 3b + 15 + 15 = 24
6b + 30 = 24 {Subtract 30 from both sides}
6b = 24 -30
6b = -6 {divide both sides by 6}
b = -6/6
b = -1
a + b = 3 + ( -1)
= 2

What is the slope of y = 4 - 2x
compare with y=mx+c
then
y=4-2x
y=-2x+4
c=4,m=-2
Answer:
slope = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4 - 2x , that is
y = - 2x + 4 ← is in slope- intercept form
with slope m = - 2
