Answer: 84, 35
Step-by-step explanation:
12*7=84
5*7=35
84-35=49
The two numbers are 35 and 84
Let the two numbers be x and y
If the ratio are in 12: 5, hence:
x/y = 12/5
5x = 12y
x = 12y/5
If their difference is 49, then;
x - y = 49 .................. 2
12y/5 - y = 49
7y/5 = 39
7y = 49 * 5
y = 7 * 5
y = 35
Recall that x - y = 49
x = 49 + y
x = 49 + 35
x = 84
Hence the two numbers are 35 and 84

Fossils show that
insects were much larger around 300 million
years ago than they are today. The table at
the right shows some of the wing lengths
found in fossils. How much longer was the
wing length of the dragonfly than the wing
length of the fly?
Answer:
The wing of the dragonfly was 9.65 cm longer than that of the fly, 102% larger in percentage terms.
Step-by-step explanation:
Since the length of the wing of the old dragonfly was 19.5 cm, while the length of the wing of a common fly is 9.85 cm, to determine how long the dragonfly's wing was compared to that of the fly, the following must be done calculations:
19.5 - 9.85 = X
9.65 = X
Thus, the wing of the dragonfly was 9.65 cm longer than that of the fly. In turn, in terms of percentages, the result is the following:
9.65 = 100
19.5 = X
19.5 x 100 / 9.65 = X
1950 / 9.65 = X
202 = X
Thus, in percentage terms, the dragonfly's wing was 102% larger than that of the current fly.

Answer:
Top left: a is negative and p is positive
Step-by-step explanation:
The formula y = ax + p is referring to the formula y = mx + b where m is the slope and b is the y-intercept.
Since the line is going down, the slope is negative-- a is negative.
Since the line crosses the y-axis above the origin, the y-intercept is positive-- p is positive.
Answer:
a is negative and p is positive
Step-by-step explanation:
The equation y = ax + p is written in slope-intercept form, where a is the slope and p is the y-intercept.
When a slope is negative, the line goes down the further right it goes.
The line on the graph lowers as it moves right, which means that the slope(a) is negative.
The line intercepts the y-axis above the origin, which means that it must be positive.
a sporting goods manufacturer requires 2/5yd of fabrick to a pair of soccer shorts how many shorts can be made from 4yd of fabric
Answer:
10 pair of soccer shorts.
Step-by-step explanation:
Let the unknown be x.
Translating the word problem into an algebraic equation, we have;
2/5 yard = 1 pair of short
4 yard = x pair of short
Cross-multiplying, we have;
2x/5 = 4
Multiplying both sides by 5, we have;
2x = 20
x = 20/2
x = 10 pair of soccer shorts.

What is triangle equality theorem?This theorem simply states that the sum of two sides of a triangle must be greater than the third side. If this is true for all three combinations, then you will have a valid triangle.
If triangle has the sides, a , b and c then
a + b > c
b + c > a
a + c > b
Given length of the sides,
a) Triangle made with sides having length 3 inch, 4 inch, 6 inch.
3 + 4 > 6 ; 4 + 6 > 3 ; 3 + 6 > 4
= 7 > 6 ; 10 > 3 ; 9 > 4
Triangle inequality theorem is satisfied, hence triangle construction is possible
b) Triangle made with sides having length 2 inch, 3 inch, 5 inch.
2 + 3 > 5 ; 3 + 5 > 2 ; 2 + 5 > 3
= 5 = 5 ; 8 > 3 ; 7 > 3
Triangle inequality theorem is not satisfied, hence triangle construction is not possible
a) Triangle made with sides having length 3 inch, 3 inch, 4 inch.
3 + 3 > 4 ; 3 + 4 > 3 ; 3 + 4 > 3
= 6 > 4 ; 7 > 3 ; 7 > 3
Triangle inequality theorem is satisfied, hence triangle construction is possible
a) Triangle made with sides having length 5 inch, 5 inch, 5 inch.
5 + 5 > 5 ; 5 + 5 > 5 ; 5 + 5 > 5
= 10 > 5 ; 10 > 5 ; 10 > 5
Triangle inequality theorem is satisfied, hence triangle construction is possible.
Hence, Triangle with side measurements of 2 inch , 3 inch , and 5 inch is not possible to construct.

Kristin wants to buy a pair of jeans that cost $35 and are on sale
20% off. She is also buying two T-shirts at a full price of $9.99 each.
She must pay 6.5% sales tax. How much will she pay for the clothes
Answer:
$51.10
Step-by-step explanation:
First, find 20% of $35, then add the sale price of the jeans and the two t-shirts. Take the total and find the sales tax and add that onto the cost.
100 - 20 = 80 If you multiply the jeans by 80% it gives you the price for the jeans saving you from having to subtract the discount from the original price.
35 * 0.80 = $28.00 jeans 28.00 47.98

The mean diameter of the rim of Honda tires is 16 inches. Assume that the standard deviation of diameter of the rims is 0.3 inches. For quality control purposes, the diameter of the rims of 9 tires is measured every hour. The manager applies the rule that if the mean of diameter of a rim is greater or equal to 16.25, and lesser or equal to 15.75, the manufacturing should be stopped. If the diameter is between 15.75 and 16.25, the manufacturing process is not to be disturbed. a. Calculate the probability of stopping the manufacturing when the sample mean is 16 inches. b. Calculate the probability of stopping the manufacturing in case the mean is shifted to 16.05 inches. c. Calculate the probability of not disturbing the manufacturing if mean shifts to 16.25 inches.
Answer:
a. 0.0124 = 1.24% probability of stopping the manufacturing when the sample mean is 16 inches.
b. 0.0241 = 2.41% probability of stopping the manufacturing in case the mean is shifted to 16.05 inches.
c. 0.5 = 50% probability of not disturbing the manufacturing if mean shifts to 16.25 inches.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
Assume that the standard deviation of diameter of the rims is 0.3 inches. Samples of 9.
This means that [tex]\sigma = 0.3, n = 9, s = \frac{0.3}{\sqrt{9}} = 0.1[/tex]
a. Calculate the probability of stopping the manufacturing when the sample mean is 16 inches.
Here we have [tex]\mu = 16[/tex]
Higher than 16.25:
This is 1 subtracted by the pvalue of Z when X = 16.25. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{16.25 - 16}{0.1}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a pvalue of 0.9938
1 - 0.9938 = 0.0062
Lower than 15.75:
This is the pvalue of Z when X = 15.75. So
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{15.75 - 16}{0.1}[/tex]
[tex]Z = -2.5[/tex]
[tex]Z = -2.5[/tex] has a pvalue of 0.0062
Probability of stopping:
2*0.0062 = 0.0124
0.0124 = 1.24% probability of stopping the manufacturing when the sample mean is 16 inches.
b. Calculate the probability of stopping the manufacturing in case the mean is shifted to 16.05 inches.
Here we have [tex]\mu = 16.05[/tex]
Higher than 16.25:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{16.25 - 16.05}{0.1}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a pvalue of 0.9772
1 - 0.9772 = 0.0228
Lower than 15.75:
This is the pvalue of Z when X = 15.75. So
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{15.75 - 16.05}{0.1}[/tex]
[tex]Z = -3[/tex]
[tex]Z = -3[/tex] has a pvalue of 0.0013
Probability of stopping:
0.0228 + 0.0013 = 0.0241
0.0241 = 2.41% probability of stopping the manufacturing in case the mean is shifted to 16.05 inches.
c. Calculate the probability of not disturbing the manufacturing if mean shifts to 16.25 inches.
Between 16.25 and 15.75 with [tex]\mu = 16.25[/tex]. This is the pvalue of Z when X = 16.25 subtracted by the pvalue of Z when X = 15.75.
X = 16.25
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{16.25 - 16.25}{0.1}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a pvalue of 0.5
X = 15.75
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{15.75 - 16.25}{0.1}[/tex]
[tex]Z = -5[/tex]
[tex]Z = -5[/tex] has a pvalue of 0
0.5 - 0 = 0.5
0.5 = 50% probability of not disturbing the manufacturing if mean shifts to 16.25 inches.
