What is the value of 3^5 times 3^3 divided by 3^4
Answer:
3^4
Step-by-step explanation:
One of the laws of exponents is that when you are multiplying exponents with the same base, then you add their powers. So,
3^5 x 3^3 = 3^8
Another law is when dividing exponents with the same base, you can subtract the powers. So,
3^8/3^4 = 3^4

Pls help me with the answer and explanation
Answer:
10
Step-by-step explanation:
Calculate the length using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+ (y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 3, - 4) and (x₂, y₂ ) = (5, 2)
d = [tex]\sqrt{(5+3)^2+(2+4)^2}[/tex]
= [tex]\sqrt{8^2+6^2}[/tex]
= [tex]\sqrt{64+36}[/tex]
= [tex]\sqrt{100}[/tex] = 10
An angle measures 50° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
20° and 70°
Step-by-step explanation:
Complementary angles sum up to 90°.
The angle = x
Its complement = x + 50
x + x + 50 = 90
2x = 40
x° = 20°
20+50=70
Answer: 70° and 20°
Step-by-step explanation:
Complementary angles add up to 90 degrees and we now that one angles measure is 50 degrees less than the other. So we can represent it by the expression x = y -50 where x and y are the two angles. We don't the value of y so it will be just y .
Now we know that if we add them,they will equation 90 degrees so we can represent it by the equation,
y + y-50 = 90 Now solve for y
2y - 50 = 90
+50 +50
2y = 140
y = 70
Now we know one angles is 70 degrees and the other is 50 less than it so the other angle will be 70 - 50 = 20

The equation to represent Jason’s job is y = 9x, where x is the number of hours he works and y is the total amount he earns. Mia has applied to be a lifeguard for the summer. The lifeguard job is three days a week with hours and pay as shown in the table below. Tuesday Thursday Saturday Hours worked 6 8 5 Amount paid $52.50 $70.00 $43.75 Which statement best describes the hourly rates? The two jobs pay the same hourly rate. The comparison cannot be made with the information given. Jason’s camp counselor job pays a higher hourly rate than Mia’s lifeguard job. Jason’s camp counselor job pays a lower hourly rate than Mia’s lifeguard job.
Answer:
Jason's camp counselor job pays a higher rate than Mia's lifeguard job.
Jason's job pays $9 a hour.
Mia's job pays $8.75 a hour.
52.50 divided by 6 equals 8.75
70.00 divided by 8 equals 8.75
43.75 divided by 5 equals 8.75

mathematics question in the screenshot below.
Step-by-step explanation:
1/6×100%=50/3%
3/24×100%=25/4%
3/8×100%=75/2%
=>50/3%+25/4%+75/2%+x=100%
=>100%-725/12%=x
=>x=59 and 5/12
Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
13
8
Answer:
129.1 square units
Step-by-step explanation:
First, let's find the area of the rectangle. We can use the formula below.
[tex]a=lw[/tex]
where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
The length of the rectangle is 13 and the width is 8.
[tex]l=13\\w=8[/tex]
Substitute the values into the formula.
[tex]a=13*8[/tex]
[tex]a=104[/tex]
Next, let's find the area of the semicircle. We can use the formula below.
[tex]a=\frac{1}{2} *\pi r^2[/tex]
First, find the radius. The radius is half of the diameter, and the diameter is 8.
⇒ r= d/2
⇒ r= 8/2
⇒ r= 4
[tex]a=\frac{1}{2} *\pi (4)^2[/tex]
Evaluate the exponent.
⇒ 4² = 4*4 = 16
[tex]a=\frac{1}{2} *\pi *16[/tex]
Multiply pi and 16.
[tex]a=\frac{1}{2} *50.2654825[/tex]
Multiply.
[tex]a=25.1327412[/tex]
Finally, find the area of the figure.
Add the area of the rectangle (104) and the area of the semicircle (25.1327412)
[tex]104+25.1327412[/tex]
[tex]129.132741[/tex]
Round to the nearest tenth. The 3 in the hundredth place tells us to leave the 1 in the tenth place.
[tex]129.1[/tex]
The area of the figure is about 129.1 (square units).
Write an equation for a line that is parallel to 2x+5y=15 and passes through the point (-10, 3)
Answer:
The equation of the line is,
[tex]y = - \frac{2}{5} x - 1[/tex]
Step-by-step explanation:
First, you have to write it in a form of y = mx + b :
[tex]2x + 5y = 15[/tex]
[tex]5y = 15 - 2x[/tex]
[tex]y = 3 - \frac{2}{5} x[/tex]
[tex]y = - \frac{2}{3} x + 5[/tex]
When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :
[tex]y = - \frac{ 2}{5}x + b [/tex]
[tex]let \: x = - 10,y = 3[/tex]
[tex]3 = - \frac{2}{5} ( - 10) + b[/tex]
[tex]3 = 4 + b[/tex]
[tex]3 - 4 = b[/tex]
[tex]b = - 1[/tex]
Answer:
the equation of a parallel line is : y=-2/5 x -1
Step-by-step explanation:
2x+5y=15
put the equation in the form of y=mx+b
2x+5y=15
5y=15-2x
y=15/5-2/5 x
y=-2/5 x+3
parallel lines has the same slope : m=-2/5
passes through point (-10,3) find b
y=-2/5 x +b
3=-2/5(-10)+b
3=20/5 +b
3=4+b
b=3-4
b=-1
the equation of a parallel line is : y=-2/5 x -1

Given the function f(x)=2x-4 find x if f(x)=10
Answer:
7
Step-by-step explanation:
Since f(x)=10 is equivalent to f(x)=2x-4, make these equations equivalent. Add 4 to both sides, and simplify to get 2x=14. Divide both sides by 2 to get 7 as your answer.
Answer:
x = 7
Step-by-step explanation:
Given
f(x) = 2x - 4 and f(x) = 10, then equating gives
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Two forces are given by j = (-2,1] and K = (-5,3), in
Newtons. What is the magnitude of j+k ?
Answer:
[tex]\sqrt{65}[/tex]
Step-by-step explanation:
The magnitude of a vector < x, y > is calculated as
| < x, y > | = [tex]\sqrt{x^2+y^2}[/tex]
Thus
j + k = < - 2, 1 > + < - 5, 3 > = < - 2 - 5, 1 + 3 > = < - 7, 4 >
Then
| < - 7, 4 > | = [tex]\sqrt{(-7)^2+4^2}[/tex] = [tex]\sqrt{49+16}[/tex] = [tex]\sqrt{65}[/tex]
Which of the following describes a situation where the total distance a person traveled is 0 feet from the starting point? A. Wyatt drove 25 miles west and then 10 miles in the opposite direction B. Wyatt drove 25 miles east and then 25 in the opposite direction C. Wyatt drove 25 miles north then 20 miles in the opposite direction D. Wyatt drove 25 miles south and then 19 miles in the opposite direction
Answer:
B. Wyatt drove 25 miles East and then 25 miles in the opposite direction
Step-by-step explanation:
This is because he drove East but then drove the same distance back, so he is basically cancelling out the distance he already traveled. Therefore, the traveled 0 feet from the starting point.
Answer:
B. Wyatt drove 25 miles east and then 25 in the opposite direction
Step-by-step explanation:
if you drive x amount of miles in one direction and then the oposite you return where you statred.
ugh no body knows this? Suppose a square garden represented by 16x2 ft2. a. What is the length of each side? b. What is the perimeter of the garden? c. If each side was increased by 5 feet what would be the new perimeter?
Answer:
A. [tex]4x[/tex]
B. [tex]16x[/tex]
C. [tex]16x+20[/tex]
Step-by-step explanation:
A square's area will be the length of each side squared (that's why it's called squared).
Since we know the area, we can find the square root of [tex]16x^2[/tex] to find the length of each side.
We know that [tex]4^2 = 16[/tex] and [tex]x^2 = x^2[/tex], so [tex]4x\cdot 4x[/tex] should be equal to [tex]16x^2[/tex].
This means the side length is [tex]4x[/tex].
The perimeter of a square will be 4 times it's side length. We know the side length, so the perimeter is [tex]4x \cdot 4 = 16x[/tex].
If we added 5 to the length of each side, the new side length would be [tex]4x + 5[/tex]. Again, the perimeter is 4 times the side length so the perimeter would be [tex]4(4x + 5) = 16x + 20[/tex].

D is between C and E, CD = x 2 , CE = 32-2x, and DE = 12x. Find CD, DE, and CE.
Answer:
CD = 4DE = 24CE = 28Step-by-step explanation:
The segment addition theorem tells you ...
CD +DE = CE
x^2 +12x = 32 -2x
Subtract the right side to put this in standard form.
x^2 +14x -32 = 0
(x +16)(x -2) = 0
x = -16 or 2
In order for DE to have a positive length, we must have x > 0. So ...
CD = x^2 = 2^2 = 4
DE = 12x = 12(2) = 24
CE = 32 -2x = 32 -2(2) = 28
