is the 72 or right or nah this is way to confusing for me

Answers

Answer:

36mm2

Step-by-step explanation:

The ratio between sides is:

[tex]\frac{12}{8}[/tex]

Since this is the proportional area, we square this ratio

[tex](\frac{12}{8} )^{2}=\frac{12^{2} }{8^{2} }= \frac{144}{64} =2.25[/tex]

If the minor triangle has an area of 16 mm2, then the greater triangle will have an area of:

[tex]16(2.25)=36mm^{2}[/tex]

the mayor is hoping to develop a new outdoor park area. he decides to survey the town residents by surveying YMCA member on a Saturday morning. Is this a random sample? Justify your answer.

it is not a random sample because it is not a good representative for all the population because what the mayor can do is to choose a random sample for all people or everyone that live in the town to get the best results he can get because if he does survey ymca he would not get the results that he expected so hopefully that is the correct answer or explanation.

The coach for a basketball team wants to buy new shoes for her 12 players.

Super Sports is offering a 20% discount on each pair of shoes, which were originally priced $72.50. A 6.5% sales tax will be applied to the discounted price.

The same shoes are also available on Double Dribble’s website for $54.75. A 9% processing fee will be applied to the cost of the shoes, plus a shipping fee of $5.99 for each pair.

What is the difference in the total cost of the 12 pairs of shoes between the two stores?

Answers

Answer:

46.77

Step-by-step explanation:

First, we need to determine what the final price is for each pair in these two stores. In Super Sports, the shoes were originally $72.50, but they had a 20% discount. This means that you would pay for 80% (0.8) of the price:

72.50 * 0.8 = 58

A 6.5% sales tax will be applied to the discounted price. This means you would pay for 106.5% of the price:

58 * 1.065 = 61.77

On the other hand, at Double Dribble, the shoes are originally $54.75. A 9% processing fee is applied to this:

54.75 * 1.09 = 59.67

plus a shipping fee of $5.99:

59.67 + 5.99 = 65.67

If we were to buy 12 pairs of shoes, the prices would be:

Store A: 61.77 * 12 = 741.24

Store B: 65.67 * 12 = 788.01

The difference would be $46.77 (788.01 - 741.24).

what is Number line?

A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present. The use of the number is determined by the question that it corresponds to, such as when graphing a point.

The horizontal straight lines known as number lines are where integers are arranged in equal intervals. A number line can be used to represent every number in a sequence. The endpoints of this line go on forever. Integers are arranged on a number line in the image above.

Given:

a) 4.6 + (–5.9)

( The arrow will be on 4.6 and move the arrow right of of the number line to reach -5.9)

Using Integers,

4.6 - 5.9 = -1.3

b) ) –4.4 + 6.2

= 1.8

( The arrow will be on -4.4 and move the arrow right of of the number line to reach  6.2 units)

c) 2.1 + 0.5

= 2.6

d)  –3.8 + (–1.3)

= -3.8 - 1.3

= -4.6

As, in number line to perform addition the arrow move to right side of number line and to perform subtraction the arrow move left side.
