Answer:
It'll take 7 hours for the car B to cath up to A
Step-by-step explanation:
In order to solve this problem we can write the equation from the distance of each car. Assuming that t = 0 happens when the second car leaves Toronto. When the second car leaves Toronto, the first one is on the road for two hours already, thefeore it travelled a total of:
distance = speed*time = 70*2 = 140
We have:
Car A:
x(t) = 70*t + 140
Car B:
x(t) = 90*t
We now need to find the value of "t" that makes x(t) the same for both cars:
90*t = 70*t + 140
20*t = 140
t = 140 / 20 = 7 h

1) Tanya is buying edging for a triangular flower garden she plans to build in her backyard. If the lengths of the three pieces of edging that she purchases are 13 feet, 10 feet, and 7 feet, will the flower garden be in the shape of a right triangle ?
Answer:
• In a right triangle, the two sides adjacent to the
right angle are known as the _________, or
______ and ______.
• The side opposite from the right angle
is called the ___________________, or ______.
• The hypotenuse is always the _______________ side of a right triangle.
Step-by-step explanation:
Answer:
The Flower Garden is not in the shape of a right Δ
Step-by-step explanation:
~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~
Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;
a^2 + b^2 = c^2,
10^2 + 7^2 = 13^2,
100 + 49 = 169,
149 ≠ 169,
So the Flower Garden will not be in the shape of a right Δ

Stephen and Alice are reading the same book for a book club. Stephen reads
278 pages in 7 weeks. Alice reads 31 pages each week. About how many more
pages does Stephen read each week than Alice?
20
70
o
10
Answer:
10
Step-by-step explanation:
Stephen 278 pages in 7 weeks. Divide 278 by 7 to get 39.71 pages per week. 39.71 rounds up to 40, and 40 is about 10 more than 31.
There are more 9 pages does Stephen read each week than Alice.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Stephen reads 278 pages in 7 weeks.
And, Alice reads 31 pages each week.
Here, Stephen reads 278 pages in 7 weeks.
Hence, Number of pages read in 1 week = 278 / 7
= 40
And, Alice reads 31 pages each week.
Thus, Number of more pages Stephen read each week than Alice is,
⇒ 40 - 31
⇒ 9

Answer:
∠ A = 31.3°, ∠ C = 58.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{25}[/tex] , thus
∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{13}{25}[/tex] ) ≈ 31.3° ( to the nearest tenth )
The sum of the 3 angles in a triangle = 180° , thus
∠ C = 180° - (90 + 31.3)° = 180° - 121.3° = 58.7°

Lei pre sold 32 carnations for a fundraiser, then she sold c more carnations on the day of the fundraiser. She earned 0.25 dollars for each carnation she sold. The expression 8+ 0.25c describes how much money Lei earned for the fundraiser. We can also use the expression 0.25(32+c) to represent the same quantity. Help me Create another Expression please.
Answer I WILL GIVE BRAINLIEST!
Answer: [tex]0.5 * (16 + 0.5c)[/tex]
Step-by-step explanation:
Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.
For instance, if Lei sold 4 carnations:
[tex]8 + 0.25 (4) = 9\\\\0.25 * (32 + 4) = 9[/tex]
In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.
You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:
[tex]0.5 * (16 + 0.5c)[/tex]
If Lei sold 4 carnations:
0.5 * (16 + 2) = 9
This equation represents the same quantities as the other equations.

3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6
Answer:
5 3/8
Step-by-step explanation:
3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6
Get a common denominator for the right side
3 1/8 ÷(x−4 7/28 )= 17/18 +1 15/18
Combine like terms
3 1/8 ÷(x−4 7/28 )= 1 32/18
3 1/8 ÷(x−4 7/28 )= 2 14/18
3 1/8 ÷(x−4 7/28 )= 2 7/9
We have a ÷ b = c
Rewriting as a ÷c = b
3 1/8 ÷ 2 7/9 = (x−4 7/28 )
Changing from mixed numbers to improper fractions
25/8 ÷ 25 /9 = (x−4 7/28 )
Copy dot flip
25/8 * 9/25 = (x−4 7/28 )
9/8 = (x−4 7/28 )
Add 4 7/28 to each side
9/8 + 4 7/28 = (x−4 7/28 )+ 4 7/28
Simplifying the fractions
9/8 + 4 1/4 = x
Getting a common denominator
9/8 + 4 2/8 =x
4 11/8 =x
4 + 8/8+3/8 =x
