Answer:

A. None of these

Step-by-step explanation:

The largest perfect square under 100 would actually be 81 (9 x 9)

90 and 99 are not perfect squares and 64 is smaller than 81.

Answer:

a. none of these

Step-by-step explanation:

10 * 10 = 100, so 100 is a perfect square.

The next smaller perfect square is 9 * 9 = 81, but 81 is not in the choices.

Find the midpoint of points A(8,-7) and B(3,-1) graphically

sukhopar [10]

Answer: (5.5, -4)

Step-by-step explanation:

You can use the midpoint formula to find the midpoint of point A and point B.

$M(\frac{x_{1}+x_{2} }{2}, \frac{y_{1} + y_{2} }{2})$

x₁ = 8

x₂ = 3

y₁ = -7

y₂ = -1

$M(\frac{x_{1}+x_{2} }{2}, \frac{y_{1} + y_{2} }{2})$

$M(\frac{8+3 }{2}, \frac{-7 +-1}{2} )$

$M(\frac{8+3 }{2}, \frac{-7 -1}{2} )$

$M(\frac{11 }{2}, \frac{-8}{2} )$

$M(5.5, -4 )$

Midpoint = (5.5, -4)

Hope this helps!

At sunset the temperature was 4 dgrees. the next morning at sunset it was -7 degrees. what is the difference betweeen these temp

DedPeter [7]

The difference between these temperatures for the sunset is found as 11 degrees.

<h3>What is temperature difference?</h3>

In science, the term Delta T (ΔT) refers to the temperature between two measuring points. The temperature varies according to time and/or location.

Some key features regarding the temperature difference are-

Merus, for example, uses it to assess the effectiveness of such a heat exchanger.
Or to evaluate the effectiveness of a heating or cooling system.
A fourth letter of a Greek alphabet is, (Δ). Whereas is the capital letter symbol and the lower case letter.
The sign is also used in mathematics. Describes the "difference" between any two changeable quantities. T is a value in a process that represents a difference between two observed temperatures.

Now, according to the question;

Let the initial temperature be 'T' = 4 degrees.

Let the final temperature be 't' = -7 degrees.

Therefore, the temperature difference is;

ΔT = T - t

= 4 - (-7)

= 4 + 7

ΔT = 11

Therefore, the difference between these temperatures is 11 degrees.

PLEASE HELPPP ASAP, NEED THIS DUEEE ASAP

valentina_108 [34]

Answer:

Proportional relationship.

Step-by-step explanation:

From the given table, let us find the ratio of each pair of time and distance.

The first pair is 2 and 90.

Therefore, the ratio is $r=\frac{90}{2}=45$

The second pair is 3 and 135.

Therefore, the ratio is $r=\frac{135}{3}=45$

The third pair is 5 and 225.

Therefore, the ratio is $r=\frac{225}{5}=45$

The fourth pair is 6 and 270.

Therefore, the ratio is $r=\frac{270}{6}=45$

Since, the ratio of each pair is same and equal to 45, therefore, the relationship is proportional relationship.
