Answer:
Answer is C
Step-by-step explanation:
It tells you on the graph paper that 1 square is 6 meters.
The problem says the Post Office is 60 meters long, in its longest dimension
The outine on the graph paper is 10 squares long on the longest side.
10 squares to represent 60 meters is 60 meters/10 squares = 6 meters per square
So we are shown in more than one way that a square on the graph paper represents a length of 6 meters.
Now, for the answers A,B,C, and D.
A is wrong because it says 6 squares for 1 meter. But it is actually the other way around, 6 meters for 1 square.
In B, C, and D they get the 6 meters /1 square part right. But these are proportions, where two fractions are stated to be equalt to each other. Which proportion is true?
There is an easy way to check!
IF a/b = c/d, for real, then ad = bc. (The product of the means equals the product of the extremes.) That is a rule in proportions, and is always mathematically true as long as there are no undefined terms (like zero in a denominator).
So if ad = bc, then B says that 360 = 10. False.
If ad = bc, then C says that 60 = 60. True.
If ad = bc, then D says that 360 = 10. false.
The answer is C

A jacket with an original price of $160 is on sale for 15% off what is the sale price
Answers
Answer:

Step-by-step explanation:
Multiply 160 by 0.15 to find what 15% of 160. The answer is 22.5. Then subtract 22.5 from 160 to find the answer (137.50)
Answer:
$136
Step-by-step explanation:
To solve percent problems, you can use the formula part %
------- = -----
whole 100
The % would be 15, the whole would be 160, and the part would be x. Cross multiply to get 100x = 2400. Divide 2400 by 100 to get x = 24. Then, subtract 24 from $160 to get $136. The sale price is $136.

Answers
Step-by-step explanation:
9x+4+2x=180
= 11x=176
= x=176/11
=x=16
2x=32°
9x+4=148°
The measure of two angles are 2x=31.6° and (9x+4)°=146.4°.
From the given figure, there are two angles 2x° and (9x+4)°.
What are adjacent angles?Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.
Here,
2x°+(9x+4)°=180° (Sum of two adjacent angles is 180°)
⇒ 11x+4=180
⇒ 11x=174
⇒ x=174/11
⇒ x=15.8°
So, 2x=31.6° and (9x+4)°=146.4°
Therefore, the measure of two angles are 2x=31.6° and (9x+4)°=146.4°.

Convince Me! There are two outputs of 24. Does this
help you determine whether the relation is a function?
Explain.
Answers
Answer:
For the first question, No, because there is 2 inputs and only 1 output so it is not a function.
Convince me: This does help you find whether it is a function or not. Since 24 has two outputs, it is not a function.
Step-by-step explanation:
Convice me explain: The reason is that is for a function to be a function, there must be one input for one output, it can't have two different outputs.
Hence, it is not a function because one input should have one output not more than you.
What is the ordered pairs?
An ordered pair [tex](a, b)[/tex] is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair [tex](a, b)[/tex] is different from the ordered pair [tex](b, a)[/tex] unless [tex]a = b[/tex].
(A) No, because there is only two inputs and which have only one output so it is not a function.
Convince me: It does help to you find whether it is a function or not. Since [tex]24[/tex] has two outputs,so it is not a function. So, one input have only one ouput not more than one.

A factory received a shipment of 19 bolts, and the vendor who sold the items knows there are 7 bolts in the shipment that are defective. Before the receiving foreman accepts the delivery, he samples the shipment, and if too many of the bolts in the sample are defective, he will refuse the shipment. For each of the following, give your responses as reduced fractions. If a sample of 7 bolts is selected, find the probability that all in the sample are defective. If a sample of 7 bolts is selected, find the probability that none in the sample are defective.
Answers
Answer:18
Step-by-step explanation: 19-7=12 bolts and 7+7=14 so 12-14=18
If a sample of 7 bolts is selected, then the probability that all in the sample are defective = [tex]\frac{7}{50388}[/tex]
If a sample of 7 bolts is selected, then the probability that none in the sample are defective = [tex]\frac{66}{4199}[/tex]
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.
What is the formula for combination?[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]
For given question,
Out of 19 bolts, 7 bolts are defective.
So 19 - 7 = 12 bolts are non-defective.
If sample of 7 bolts is selected.
The total number of ways of selecting 7 bolts from the 19 bolts.
Using combination formula,
[tex]^{19}C_7\\\\=\frac{19!}{7!(19-7)!} \\\\=50388[/tex]
Let event A: all bolts in the sample are defective
n(A) = 7
So the probability that all in the sample are defective would be,
[tex]P(A)=\frac{7}{50388}[/tex]
Let event B: no bolt in the sample are defective
This means the sample of 7 bolts has non-defective.
The total number of ways of selecting 7 bolts from the 12 non-defective bolts.
Using combination formula,
[tex]^{12}C_7\\=\frac{12!}{7!(12-7)!}\\\\ =792[/tex]
son n(B) = 792
So, the probability that none in the sample are defective would be,
[tex]P(B)=\frac{792}{50388} \\\\P(B)=\frac{66}{4199}[/tex]
Therefore, If a sample of 7 bolts is selected, then the probability that all bolts in the sample are defective = [tex]\frac{7}{50388}[/tex]
If a sample of 7 bolts is selected, then the probability that none in the sample are defective = [tex]\frac{66}{4199}[/tex]

The reason why is because the human is 4 feet since it says that 1/2 inch on the scale is 2 feet and the human is 1 inch on the scale so the human is 4 feet.
The dino is 8 feet since it goes to 2 inches on the scale which means 8 feet. The difference between 4 and 8 is 4, so 5 feet is the approximate for this problem.

Answers
Answer:
i = 87
Step-by-step explanation:
First, you would distribute 5 through the parenthesis by multiplying everything inside by 5. So 5*21=105 and 5*4=20. Next, you would add them together and simplify the equation to 125 - i = 38. Then you would subtract 38 from 125 to receive the equation 87 - i = 0. Finally, you would add i to both sides and get i = 87.

Answers
Answer:
(0,inf)
Step-by-step explanation:
The range is the y-values included in the graph. This function is exponential decay, which means it has a horizontal asymptote. A function will never cross or touch the horizontal asymptote. Since the asymptote for this graph is y=0, the lowest y-value will be 0, however it is not an included value. Then, the graph will reach every y-value above 0, so the highest range will be infinity.
