Answer:
The answer is "The product is greater than 3/8 and less than 7/2"
Step-by-step explanation:
This is because the product of 3/8 and 7/2 is 21/16.
When you simplify 21/16, you get 1 and 5/16 which is greater than 3/8 but less than 7/2, which simplified is 3 and 1/2.
You can solve this in two ways.
First way:
Let’s find out how many my friend makes in one minute.
12/5=2.4
He makes 2.4 in one minute. Let’s multiply that by 20 to find what he makes in 20 minutes.
2.4•20=48
My friend made 48 desserts.
Second way:
Let’s make a ratio.
12 desserts:5 minutes
X desserts: 20 minutes
Whatever you do to one side, you have to do to the other. Since you are multiplying the minutes by 4, you have to multiply the desserts by 4.
12•4=48
So, my friend made 48 desserts.
Tell me if this helps!!!
Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
Option A:
Slope of the line is .
Solution:
Given points are (1, 1) and (7, 5).
To find the slope of the line:
Slope of the line:
Hence slope of the line is .
Option A is the correct answer.
Answer:
16.6 degrees (to nearest tenth)
Step-by-step explanation:
Angle of inclination = the angle whose sine is 2/7.
Its the sine because 7 miles = hypotenuse and elevation ,2 miles , = opposite side).
This is 16.6 degrees (to nearest tenth)
