If I do this with 4 and 5 - I get 29. If I do the same thing with 4 and 6 - I get 40. Thesame thing again to 8 and 9 gives me 89. What do I get if I do the same thing to 5 and 8?
Answer: 69
Step-by-step explanation:
If I do this with 4 and 5 - I get 29.
This can be explained as this:
4 + (5^2) = 4 + 25 = 29
If I do the same thing with 4 and 6 - I get 40. This can be explained as:
4 + (6^2) = 4 + 36 = 40
Thesame thing again to 8 and 9 gives me 89. This can be explained as:
8 + (9^2) = 8 + 81 = 89
What do I get if I do the same thing to 5 and 8. This will be:
5 + (8^2) = 5 + 64 = 69
Jen rode her bike 1/5 of a mile to her friend's house. It took her 5 minutes to get there. What was Jen's speed?
Jen's speed is 0.04 miles per minute.
Explanation:To find Jen's speed, we need to divide the distance she traveled by the time it took her to get there. In this case, Jen traveled 1/5 of a mile and it took her 5 minutes. To find her speed in miles per minute, we divide the distance (1/5 mile) by the time (5 minutes):
Speed = Distance ÷ Time
Speed = 1/5 mile ÷ 5 minutes
To simplify the calculation, we can convert 1/5 mile to a decimal by dividing 1 by 5:
1/5 = 0.2
Now we can divide 0.2 by 5 to find Jen's speed:
0.2 ÷ 5 = 0.04
Therefore, Jen's speed is 0.04 miles per minute.

Determine the slope and y-intercept. 4x + y = -10
Answer:
Y intercept is -10
Step-by-step explanation:
Answer:
slope = -4
y-intercept = -10
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 4x from both sides:
4x (-4x) + y = -10 (-4x)
y = -4x - 10
Note the slope intercept form: y = mx + b
y = y
m = slope = -4
x = x
b = y-intercept = -10
slope = -4
y-intercept = -10
What is the radius of the circle with the following equation (x+1)²+ (y-3)²= 64? *

In ADEF, DE = 25 cm, EF = 17 cm, and DF -- 20 cm
Which angle in the triangle is the smallest?
Answer:
angle FBE
Step-by-step explanation:
By using the formula, the shortest angle is facing the shortest side
so the shortest angle is angle FBE
In triangle ADEF, angle E is the smallest angle.
Explanation:In triangle ADEF, we are given that DE = 25 cm, EF = 17 cm, and DF = 20 cm. To determine which angle is the smallest, we need to compare the lengths of the sides opposite each angle. The smallest angle will have the smallest side opposite it. Let's compare the lengths:
Side DE is opposite angle D.
Side EF is opposite angle E.
Side DF is opposite angle F.
Since side EF (length 17 cm) is the smallest, angle E is the smallest angle in triangle ADEF.

Mike and his friends hiked 23 miles on Saturday. They hiked 7 miles less than that on Sunday. Their goal is to hike a total of 50 miles during their trip. How many miles did they hike on Sunday?
Mike and his friends hiked 16 miles on Sunday. They have hiked a total of 39 miles over Saturday and Sunday, which is 11 miles short of their 50-mile goal.
Mike and his friends hiked a total of 23 miles on Saturday and hiked 7 miles less on Sunday. To find out how many miles they hiked on Sunday, we subtract 7 miles from the 23 miles they hiked on Saturday.
So, Sunday's hiking distance = Saturday's hiking distance - 7 miles
Sunday's hiking distance = 23 miles - 7 miles
Sunday's hiking distance = 16 miles.
Now, to check if they met their hiking goal of 50 miles during their trip, we add the distances hiked on both days:
Total hiking distance = Saturday's hiking distance + Sunday's hiking distance
Total hiking distance = 23 miles + 16 miles
Total hiking distance = 39 miles.
They have hiked 39 miles so far, which is short of their 50-mile goal.

Answer:
initial value: 0rate of change: 200 m/minequation: H = 200TStep-by-step explanation:
The initial value is always the value that corresponds to the independent variable being 0. Here, that's the first entry in the table. The initial Height is 0, when Time is 0.
__
The rate of change can be figured by looking at the change in Height for a change of 1 in Time. Here, the height changes by 200 m for every 1 min change in time. The rate of change is 200 m/min.
__
The equation can be written in slope intercept form using the rate of change and initial value:
(dependent variable) = (rate of change)×(independent variable) + (initial value)
H = 200T + 0
H = 200T . . . . . . . . height in meters for time in minutes
Danny read three books over winter break. The first book had 1,349 pages, the second book had 1,281 pages, and the third book had 1,195 pages. How many total pages did Danny read over the break?
Answer:
3825 pages
Step-by-step explanation:
Add the pages together:
1349+1281+1195 = 3825 pages
Danny read a total of 3,825 pages over winter break, which is well above 1,050 pages, indicating that it was very likely he had to read more than 1,050 pages.
Danny read three books over winter break. To determine the total number of pages Danny read, we need to add up the pages from each book. Here is the step-by-step explanation:
First book: 1,349 pages
Second book: 1,281 pages
Third book: 1,195 pages
Add these numbers together:
1,349 + 1,281 + 1,195 = 3,825 pages in total
Therefore, Danny read a total of 3,825 pages over the break. Clearly, this number is much greater than 1,050 pages, so without doing any calculations, we could confidently say that it's highly likely that Danny had to read more than 1,050 pages based on the individual page counts of each book provided.

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4 years; the standard deviation is 1.9 years. Use the empirical rule (68-95-99.7%) to estimate the probability of a meerkat living between 12.3 and 14.2 years.
Answer: 13.5 % would be the answer
To estimate the probability of a meerkat living between 12.3 and 14.2 years, we can use the empirical rule (68-95-99.7%).
Explanation:The probability of a meerkat living between 12.3 and 14.2 years can be estimated using the empirical rule (68-95-99.7%).
First, calculate the z-scores for the given values using the formula: z = (x - μ) / σ, where x is the given value, μ is the mean, and σ is the standard deviation. For 12.3 years:z = (12.3 - 10.4) / 1.9 = 0.947For 14.2 years:z = (14.2 - 10.4) / 1.9 = 2.000Next, use a standard normal distribution table or a calculator to find the probabilities associated with these z-scores.
The probability of a meerkat living less than 12.3 years is the same as the probability of a z-score less than 0.947.The probability of a meerkat living less than or equal to 14.2 years is the same as the probability of a z-score less than or equal to 2.000.Finally, subtract the probability of the lower value from the probability of the higher value to find the probability of a meerkat living between 12.3 and 14.2 years.
What is 1,289,845 rounded to the nearest thousand?
Answer:
1,290,000
Step-by-step explanation:
Answer:
1,290,000
Step-by-step explanation:
If we are rounding to the nearest thousand, then we are finding the number in the hundredth's and rounding it.
From 1-9 If it's less than 5, round down. If it's 5 or more, round up.
At this case, it is 8 in the hundredths and nine in the thousandths. Since 8 is 5 or greater, you round it up to 1000, but the thousandth's place has a nine, which nine plus 1 is 10.
Therefore, 1,289,845 rounded up is 1,290,000.

A. Use the formula A = one-half b h to find the area of the base.
B. Use the formula A = b h to find the area of the base.
C. The area of the base, A, is One-half (7) (8) = 28 meters squared.
D. The area of the base, A, is One-half (8) (14) = 56 meters squared.
E. The volume of the prism, V is (56) (7) = 392 meters cubed.
Answer:
Options A, D and E.
Step-by-step explanation:
Formula to calculate the volume of the triangular prism is,
Volume of the triangular prism = (Area of the triangular base)×(height)
= B × h
Area of the right triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]
= [tex]\frac{1}{2}(8)(14)[/tex]
= 56 m²
Volume of the prism = [tex](56)(7)[/tex]
= 392 cubic meter
Therefore, from the given options correct options are Option A, Option D and Option E.

Step-by-step explanation:
The cable company takes an SRS (simple random sample) of 250 of the approximately 15,000 households who subscribe to them. They found that 75% of the sampled households watch sports on television at least once a month. The company is considering taking more samples like this. Suppose that it is actually 60% of their total subscribed households who watch those sports. Let p represent the proportion of a sample of 250 households that watch sports on television at least once a month. What are the mean and standard deviation of the sampling distribution of p?
The mean of the sampling distribution of p is 0.70 and the standard deviation is 0.029 .
To find the mean and standard deviation of the sampling distribution of p , we can use the properties of sampling distributions.
Given:
Sample size, n = 250
Proportion of subscribed households who watch sports, p = 0.70 (from the population)
Sample proportion of households who watch sports, [tex]\( \hat{p} = 0.75 \)[/tex](from the sample)
The mean of the sampling distribution of p is equal to the population proportion, which is p = 0.70 .
The standard deviation of the sampling distribution of p can be calculated using the formula:
[tex]\[ \sigma_{\hat{p}} = \sqrt{\frac{p(1-p)}{n}} \][/tex]
Substituting the given values:
[tex]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.70(1-0.70)}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.70 \times 0.30}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.21}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{0.00084} \]\[ \sigma_{\hat{p}} = 0.029 \][/tex]
So, the mean of the sampling distribution of p is 0.70 and the standard deviation is 0.029 .
