Answer:

True

Step-by-step explanation:

since, S= D/T the distance traveled would only be 100m, it is a consatnt variable dividing it with the time it takes to reach that distance would be its speed. Unless there is an acceleration happening in that process the speed would change depending on the situation.

Answer:

$130.68

Step-by-step explanation:

1 acre = 43,560 square feet

3/4 of 43560 = 32,670 (So that would be 76,230 sq ft in 1.75 acres because 43560 + 32670 = 76230)

We need to divide the total by 35 plots.

76230 / 35 = 2178, using long division.

2,178 square feet is just one plot of 35. We need to multiply 2178 by 0.06.

Answer: $130.68

Which of these expressions demonstrates the identity property? 25(0) = 25 25(1) = 25 25 + 0 = 25 25 + 1 = 25
tresset_1 [31]

The expressions which demonstrates the identity property of multiplication is; 25(1) = 25 option B

<h3>Identity Property</h3>

Identity Property of Multiplication states that any number multiplied by 1 does not change, that is, it is constant or remains the same

Check all options

25(0) = 25

0 = 25

Not true

25(1) = 25

25 = 25

True (identity property of multiplication holds)

25 + 0 = 25

25 = 25

True (Not identity property of multiplication)

25 + 1 = 25

26 = 25

Not true

adoni [48]
6:50 is the answer! Hope this helps. You can figure this out by crossing out the ones you KNOW are factors of 4 and 20. And 6:50 is NOT a factor of them . Hope this helped!!

Analyze the graph of the function f(x) to complete the statement.
Burka [1]

The function f(x) is less than 0 at x < -1.8

<h3>How to analyze the graph?</h3>

The missing graph is added as an attachment

The interval where f(x) < 0 are the intervals where the y value of the function is less than 0.

This in other words, represent the negative y-axis

From the attached graph, the function f(x) is less than 0 at x < -1.8.

This extends till x = infinity

Hence, the function f(x) is less than 0 at x < -1.8
