As we know that, 1 cm = 0.01 m
So,
(a) 65 cm/s = 0.65 m/s
b) 367 km/h = (367 × 5 ÷ 18) m/s
c) 1000 cm/min = (1000 × 60 ÷ 100) m/s
d) 86 km/min = (86 × 60 ÷ 1000) m/s

3. Your test scores in science are 83 and 87. What
possible scores can you earn on your next test to have
a test average between 85 and 90, inclusive?
Answer:
Between 85 and 100
Step-by-step explanation:
Getting this will get the average between the required numbers since the average of 83 and 87 is 85, getting 85 will keep the answer at 85 and getting 100 will get the average at 90.
1.) Solve the system of equations by method of elimination. Show all your work.
2x + 4y = 8
10x – 4y = 16
Answer:
x=2, y=1
Step-by-step explanation:
Add:
2x+4y=8
+10x-4y=16
------------------
12x=24
Divide by 12 on both sides:
x=2
Substitute x with 2 on either 2x+4y=8 or 10x-4y=16 it doesn't matter it will result in the same answer.
(I will do both of them to prove it but you only need to replace x with one of the equation)
For 2x+4y=8
2(2)+4y=8
4+4y=8
Subtract 4 on both sides
-4+4+4y=8-4
4y=4
Divide 4 on both sides:
y=1
For 10x-4y=16
10(2)-4y=16
20-4y=16
-20+20-4y=16-20
-4y=-4
Divide -4 on both sides:
y=1
The answer for both 2x + 4y = 8 and 10x – 4y = 16 are the same showing that it doesn't matter which equation you replace the number with it will still result you in the same answer
Hope this helps!
At a local gym you go to, you either pay $90 fee for a monthly pass, and an additional $4 for each time you decide to go to the gym, or you can pay $13 each time you go to the gym. Write and solve a system of equations for this situation to determine how many times you have to go to the gym in order for it to cost the same amount
A. 90
В. 130
C. 10
D. 5
Answer: C. 10.
Step-by-step explanation:
Let x = Number of times you have to go to the gym in order for it to cost the same amount.
Given: Monthly pass fee = $90
Additional charge = $4
Total amount = (Monthly fee) + (Number of times) (Additional charge)
Total amount = 90+4x (i)
Payment for each time you go to the gym = $13
Total amount = 13x (ii)
From (i) and (ii) , we get
[tex]13x=90+4x\\\\\Rightarrow\ 13x-4x=90\\\\\Rightarrow\ 9x=90\\\\\Rightarrow\ x=\dfrac{90}{9}\\\\ \Rightarrow\ x= 10[/tex]
Hence, the number of times you have to go to the gym in order for it to cost the same amount= 10
Hence, the correct option is C. 10.

What is the slope of the line?
Answer:
The slope of the line is -3/2
What is the equation of the line that passes through the point (3,-5) and has a
slope of o?
Answer:
y = -5
Step-by-step explanation:
slope of 0 means m = 0 in y intercept form y = mx + b.
they have given you (3, -5), plug these in and solve for your equation.
remember, a line that has a 0 slope means it is a horizontal line.
y = mx + b
-5 = 0(3) + b
-5 = b
so you have, y = -5.

please i need helpp ion get math at all
Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21

The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode
Answer:
5 35/72 kilometers
Step-by-step explanation:
The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode
This is calculated as:
Total distance = 6 7/12 km
Evan rode = 5/6 of the distance
Hence:
The distance Evans rode is
5/6 of 6 7/12
= 5/6 × 79/12
= 395/72
= 5 35/72 km(kilometers)
What is Which equation correctly demonstrates the Distributive Property? F. $a\left(b+c\right)=ab+c$ G. $a\left(b+c\right)=ab+ac$ H. $a+\left(b+c\right)=\left(a+b\right)+\left(a+c\right)$ I. $a+\left(b+c\right)=\left(a+b\right)\cdot\left(a+c\right)$
