Answer:
80 minutes34.4 kmStep-by-step explanation:
Use the second equation to substitute for d in the first equation.
0.43t = 0.33t +8
Subtract 0.33t from both sides
0.10t = 8
Multiply by 10
t = 80 . . . . . . Michelle will catch Jen in 80 minutes
The distance traveled will be ...
d = 0.43t = 0.43×80 = 34.4 . . . . km
The girls will have traveled 34.4 km when they meet.

Calculate angle y
Can somebody work this out?
Answer:
y = 110
Step-by-step explanation:
ABCD is a cyclic quadrilateral ( its vertices are on the circle )
The opposite angles are supplementary, sum to 180° , then
∠ C = 180° - 70° = 110° , thus
y = 110
what is that area of the trapezoid
a)50in
b)108in
c)126in
b192in
Answer:
c) 126 inches of the answer
Answer:
C. 126 inches²
Step-by-step explanation:
To find the area of a trapezoid multiply the sum of the two bases (12 + 16) and the height divide by 2 (9 / 2) by each other
(12 + 16)9/2
Add 12 and 16 to get 28.
28(9/2)
Multiply 28 by 9 to get 252.
252/2
Divide 252 by 2 to get 126.
The area of the trapezoid is 126 inches².

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Given:
Jake bought 3 drawing pens for $8.07.
Each pen costs the same amount.
To find:
How much did he spend for one pen?
Solution:
Let x be the cost of each pen. Then
Cost of three pens = 3x
Jake bought 3 drawing pens for $8.07.
[tex]3x=8.07[/tex]
Divide both sides by 3.
[tex]x=\dfrac{8.07}{3}[/tex]
[tex]x=2.69[/tex]
Therefore, he spend $2.69 for one pen.

Suppose you are facing north, each time you turn, you are going to turn 90 degrees. If you turn 2 times to the right, 1 time to the left, 3 times to the right, 2 times to the right, and 1 time to the left, which way are you now facing?
Answer:
East
Step-by-step explanation:
Starting position = North
Condition = each time you turn, you are going to turn 90 degrees
Using the image attached as a guide;
If you turn 2 times to the right
- Turning the first time to the right changes the direction to East
- Turning the second time to the right changes the direction to South
1 time to the left
- Turning once to the left changes the direction to East
3 times to the right
- Turning the first time to the right changes the direction to South
- Turning the second time to the right changes the direction to West
- Turning the second time to the right changes the direction to North
2 times to the right
- Turning the first time to the right changes the direction to East
- Turning the second time to the right changes the direction to South
1 time to the left
- Turning once to the left changes the direction to East

If we changed the -3 to a 3 in the equation, what would happen to the graph?

The graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The equation y = 2ˣ⁻⁴ - 3 is an exponential function that has been shifted 4 units to the right and 3 units down from the basic exponential function y = 2ˣ.
If we change the -3 to a 3, we get the new equation:
y = 2ˣ⁻⁴ + 3
This new equation represents the original exponential function shifted 4 units to the right and 3 units up.
Therefore, the graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.

24.5 is 33 1/3% of what number?
Answer: 73.5
Step-by-step explanation:
The percent 33 1/3% represents 1/3 of 100%. We can multiply 33 1/3% by 3 and get 100%. We need to find what 24.5 is 33 1/3% of.
Since 1/3 x 3 = 100%, then 24.5 x 3 must equal the number we're trying to find.
24.5 x 3 = 73.5.
Therefore, 24.5 is 33 1/3% of 73.5. I hope this helps, and good luck!
Workout 2/7+1/5 and then simplyfy it
Answer:17/35
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(2/7, 1/5) = 35
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(2/7x5/5)+(1/5x7/7)=?
Complete the multiplication and the equation becomes
10/35+7/35=?The two fractions now have like denominators so you can add the numerators.
Then:10+7
——- =17/35
3
This fraction cannot be reduced.
Therefore:2/7+1/5=17/35
