James drove to the lake and back the trip there took four hours and the trip back took six hours he average 20 mph faster on the trip there on on the return tip find Jameses average speed on the trip
Answer: 60 mph
Step-by-step explanation:
Question wants the speed to the lake.
It took James 4 hours to get to the lake and he drove at a speed 20 mph faster than when he came back.
It took him 6 hours to come back.
Assuming the speed James used on the return trip is x:
Expression for distance is:
4(x + 20) = 6x
4x + 80 = 6x
2x = 80
x = 80/2
x = 40 mph
Speed to the lake = 40 + 20
= 60 mph

a bus traveled for 540 miles in 12 hours. was it traveling at a faster or slower rate than the car? show your work to explain
Answer:
It is at 45. So you need to determine is it faster of slower. You didn't put the whole question.
Step-by-step explanation:
If the measures of two angles of a triangle are 102° and 27°, what is the measure of the third angle?
The measure of the third angle isº
Step-by-step explanation:
therefore the third angle is 51 degrees
The pendulum swings at an arc of 30 cm and its successive swings reduced to 10% of the previous swings. What is the total distance travelled by the pendulum after 5 swings? This problem is an example of what sequence?
Answer:
[tex]S_g= 33.333cm[/tex]
Step-by-step explanation:
From the question we are told that
Arc of 30 cm
10% reduction after each swing
Generally sum of geometric sequence is given by the equation
[tex]S_g=\frac{a(1-r^n)}{1-r}[/tex]
Mathematically solving for total distance traveled we have
[tex]S_g=\frac{30(1-(0.10^5)}{1-(0.10)}[/tex]
[tex]S_g=\frac{30}{0.9}[/tex]
Therefore the total distance traveled by the pendulum after 5 swings
[tex]S_g= 33.333cm[/tex]

Round to the nearest hundredth O(5x + 2) = 2(9x - 6) Type your answer...
Answer:
Solving the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]
Step-by-step explanation:
We need to solve the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex]
Solving:
[tex]0(5x+2)=2(9x-6)[/tex]
We know that multiplying anything by zero we get zero
[tex]0=2(9x-6)[/tex]
Switching sides
[tex]2(9x-6)=0[/tex]
Multiplying 2 with terms inside the bracket
[tex]18x-12=0[/tex]
Adding 12 on both sides
[tex]18x-12+12=0+12\\18x=12[/tex]
Divide both sides by 18
[tex]\frac{18x}{18}=\frac{12}{18}\\x=0.666[/tex]
Rounding to nearest hundredth we get:
[tex]x=0.67[/tex]
So, solving the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]
Which number is equivalent to?
Andre types 208 words in 4 minutes. Noah typed 342 words in 6 minutes
A) Who typed faster
B) How many words can andre type in 10 minutes
C)Would you find the unit rate of words per minute or the unit rate of minutes per word to
figure out how long it would take Noah to write 1710 words? Why? (You do not need to
solve, just choose and explain why).
Answer:
Noah types faster because he can type more words per minute.
Step-by-step explanation:
For Andre you would divide 208 words by 4 minutes getting 52 words per minute. Then, for Noah divide 342 words by 6 minutes getting 57 words per minute.

Which of the following tables represents a function?
Answer:
The third table
Step-by-step explanation:
It's the third table because each input does not repeat, so it means all of the inputs are unique
Repeating inputs (x) make it not a function
As their is no mention of test assuming it's not a test question
Solution
Now
As per definition of function
Every domain has an unique rangef(x)=yThing we have to see here is x values must not repeated more than once
In table 3
It follows the definationTable 3 is a function
A
,
B
and
C
are points on a circle with
A
C
as a diameter.
A
B
C
is a right-angled triangle.
Work out the total area of the regions shaded in the diagram.
Give your answer correct to 1 decimal place.
Answer:
Area of the shaded portion = 54.5 cm²
Step-by-step explanation:
Solve first for the area of the circle:
[tex]area \: of \: circle = \pi {r}^{2} \\ = \pi( \frac{d}{2} )^{2} \\ = \pi( \frac{10}{2} )^{2} \\ = 25\pi \: or \: 78.5398 {cm}^{2} [/tex]
Then, compute for the area of the triangle:
[tex]area \: of \: triangle = \frac{1}{2} \times base \times height \\ = \frac{1}{2} ( {8})(6) \\ = 24 {cm}^{2} [/tex]
Since we only needed the shaded portion, we have to subtract the area of the triangle from the area of the circle
[tex]25\pi {cm}^{2} - 24 {cm}^{2} = 54.5398 {cm}^{2} [/tex]

2 sides of a triangle have measures of 5 inches and 11 inches which measure could be the length of the third side
Answer:
the third side must be greater than 6 but less than 16
Step-by-step explanation:
use triangle inequality theorem - 3 scenarios (one of which is discounted because it produces a negative and a side of a triangle cannot be negative)
5 + 11 > 3rd side (n) n < 16
5 + n > 11 n > 6
11 + n > 5; n > -6 discounted
HELp please!!!!!!!!!!!!!!!!!!!!!!11
Answer:
it’s 15x+30y-220
Step-by-step explanation:
Because you distribute and then you add the like terms

The area of a rectangle is 1,872 ft2. The ratio of the length to the width is 9:13. Find the perimeter of the rectangle. A. 88 ft B. 117 ft C. 168 ft D. 176 ft
Answer:
Length = 36
Width = 52
Step-by-step explanation:
Area of rectangle = Length * width
Length = L ; Width = W
Area (A) = 1872 ft²
Ratio L:W = 9:13
Hence,
1872 = lw - - - (1)
l/w = 9/13 - - - (2)
From (2)
13l = 9w
l = (9/13)w - - (3)
Put (3) into (1)
1872 = (9/13)w * w
1872 = 9/13 w²
24336 = 9w²
24336 / 9 = w²
2704 = w²
w = 52
If w = 52
1872 = 52 * l
l = 1872 / 52
l = 36
Length = 36
Width = 52
