The estimate of the sum of 202 and 57 is 260. You add the numbers together and than round up.
Answer:
Total Distance Michelle Covered is 26.14 miles
Step-by-step explanation:
According To the Question, We Have
Michelle First Ride Her bike In 12 miles South, then Changed her Direction & Ride Bike For A long While, and when she stopped she find Herself 2 miles south and 10 miles west from starting point. that shows she change direction and start walking in South-West Direction.
(For Diagram, Please Find in attachment)
In Triangle ABC , Apply Phythagorus Theorem
AB² = BC² + AC²
AB² = 10² + 10²
AB² = 200
AB = √2×10 ⇔ 14.14 miles
Now The Total Distance Travelled by Michelle Would be
OA + AB = 26.14 miles
Answer:
The linear model of her monthly earnings is; Y =1200 +0.03*X. The amount earned is 1350; choice A
Step-by-step explanation:
Let Y denote her monthly earnings and X her total sales. The linear model can thus be formulated as; Y =1200 +0.03*X. We are then to find the value of Y given X =5000. We simply substitute X =5000 into the linear model which yields; Y =1350
1. The solution for the equation is -16t² + 64t > 0
2. The interval notation for the equation is (0, 4)
Given,
The height of the building = 400 feet
A ball is thrown straight up from the top of the building.
The initial velocity of the ball = 64 feet/second
The height of the object is modeled by, s(t) = -16t² + 64t + 400
1. Solution for the equation:
s(t) > 400
So,
-16t² + 64t + 400 > 400
Add -400 to both sides
ie, -16t² + 64t + 400 - 400 > 400 - 400
We get,
-16t² + 64t > 0
2. Now find the interval notation for the equation:
-16t² + 64t > 0
Here, 64/16 = 4
So,
-16t (t - 4) > 0
Now,
t = 0 and t - 4 = 0
The interval notation for the equation is (0, 4)

Answer:
property of zero.
Step-by-step explanation:
It is given that, (4y + 1) × 0 = 0
. We need to tell out of four given options, which property is used in this case.
The property of zero states that if any number is multiplied by 0, then the answer is equal to 0.
Here, the number is (4y+1). It is multiplied by 0. It means that the result is 0.
Hence, it shows "property of zero".
