if 60 blimps each had 70 people on board,how many people would be riding on the blimp
By multiplying the number of blimps (60) with the number of people on each blimp (70), we find that a total of 4200 people would be riding on the blimps.
Explanation:This is a simple multiplication problem, where you simply need to multiply the number of blimps by the number of people on each blimp to get the total number of people. In this case, we have 60 blimps each carrying 70 people. So we multiply 60 blimps by 70 people to get the total number of people, which is 4200 people. Therefore, if 60 blimps each had 70 people on board, a total of 4200 people would be riding on the blimps.

On Wednesday, Miguel's bank account balance was -$55. On Thursday, his balance was less than that. Use absolute value to describe Miguel's balance on Thursday as a debt. In this situation, -$55 represents a debt of _________. On Thursday, Miguel had a debt of _____________than $55.
In this situation, the -$55 represents the debt of $55, since this happens when Miguel does not have enough money in his account to cover payments or transactions. On Thursday, he has a debt of more than $55. The explanation behind this is if an account balance is less than -55 dollars, it exemplifies a debt bigger than 55 dollars.
what is the indicated operation of
10 3/7 + 19 5/9
Final answer:
To find the sum of mixed numbers, convert them into improper fractions and then add the fractions together. The answer here is 1889/63.
Explanation:
The student’s question “what is the indicated operation of 10 3/7 + 19 5/9” asks to perform the operation of addition between two mixed numbers. The indicated operation is addition. To add these mixed numbers, you first add the whole numbers (10 + 19) and then add the fractions (3/7 + 5/9). When adding fractions, find a common denominator, in this case, 63, and convert the fractions to have this common denominator before adding.
To find the sum of mixed numbers, we first convert them into improper fractions.
10 3/7 becomes 73/7 and 19 5/9 becomes 176/9.
Then, we add the numerator of the fractions and keep the denominator the same. So, 73/7 + 176/9 = (73 * 9 + 7 * 176)/(7 * 9). Which gives 1889/63.

(–30, 10)
(80, –30)
The (–30, 10) ordered pair would form a proportional relationship with the point graphed option (C) is correct.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
The point (60, -20) is shown in the graph:
As we know from the definition of the proportional relationship:
y = kx

if (sin(()−1))p =2cos(()−1)q , show that p^2 =4q^2 (1− q^2) ?.
To show that p^2 = 4q^2(1-q^2), we use trigonometric identities and algebraic manipulations to prove the given equation sin((θ-1)p) = 2cos((θ-1)q). By taking the inverse sine, squaring both sides, and applying trigonometric identities, we arrive at the desired result.
Explanation:To show that p^2 = 4q^2(1-q^2), we need to start with the equation sin((θ-1)p) = 2cos((θ-1)q). We can use the trigonometric identities and algebraic manipulations to prove this equation.
Start by taking the inverse sine of both sides: (θ-1)p = sin^(-1)(2cos(θ-1)q).Next, use the identity sin^(-1)(x) = θ: (θ-1)p = sin^(-1)(2cos(θ-1)q) becomes p = sin^(-1)(2cos(θ-1)q)/(θ-1).Square both sides of the equation to eliminate the inverse sine: p^2 = (sin^(-1)(2cos(θ-1)q)/(θ-1))^2.Apply the identity sin^2(θ) = 1 - cos^2(θ) to the right side of the equation: p^2 = (1 - cos^2(sin^(-1)(2cos(θ-1)q)/(θ-1))))Finally, simplify the equation using algebraic manipulations to arrive at p^2 = 4q^2(1-q^2).Learn more about Trigonometry here:https://brainly.com/question/31896723

What is the probability a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 on the critical reading part of the test (to 4 decimals)? 0.6578?
The probability that the sample mean of 90 test takers falls within 10 points of the population mean of 502 is approximately 0.6578.
To find the probability that a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 on the critical reading part of the test, we need to calculate the probability using the standard normal distribution.
Given:
- Population mean [tex](\(\mu\))[/tex]: 502
- Sample size[tex](\(n\))[/tex]: 90
- Standard deviation [tex](\(\sigma\))[/tex] of the population (assumed known or provided): Let's assume it is 100 (for example purposes).
We are looking for the probability that the sample mean[tex](\(\bar{X}\))[/tex] falls within 10 points of the population mean (502 ± 10).
Step 1: Calculate the standard error of the mean (SEM):
[tex]\[ SEM = \frac{\sigma}{\sqrt{n}} \][/tex]
[tex]\[ SEM = \frac{100}{\sqrt{90}} \][/tex]
[tex]\[ SEM = \frac{100}{9.4867} \][/tex]
[tex]\[ SEM \approx 10.548 \][/tex]
Step 2: Convert the deviation of ±10 points from the mean into a z-score using the standard normal distribution:
[tex]\[ z = \frac{\text{sample mean} - \mu}{SEM} \][/tex]
For the upper bound:
[tex]\[ z_{\text{upper}} = \frac{502 + 10 - 502}{10.548} \][/tex]
[tex]\[ z_{\text{upper}} = \frac{10}{10.548} \][/tex]
[tex]\[ z_{\text{upper}} \approx 0.9497 \][/tex]
For the lower bound:
[tex]\[ z_{\text{lower}} = \frac{502 - 10 - 502}{10.548} \][/tex]
[tex]\[ z_{\text{lower}} = \frac{-10}{10.548} \][/tex]
[tex]\[ z_{\text{lower}} \approx -0.9497 \][/tex]
Step 3: Find the cumulative probabilities using the standard normal distribution table or a calculator:
[tex]\[ P(-0.9497 \leq Z \leq 0.9497) \][/tex]
Using a standard normal distribution table or a calculator, find:
[tex]\[ P(Z \leq 0.9497) \approx 0.8289 \][/tex]
[tex]\[ P(Z \leq -0.9497) \approx 0.1711 \][/tex]
Step 4: Calculate the probability that the sample mean falls within 10 points of the population mean:
[tex]\[ P(-0.9497 \leq Z \leq 0.9497) = 0.8289 - 0.1711 \][/tex]
[tex]\[ P(-0.9497 \leq Z \leq 0.9497) = 0.6578 \][/tex]
Therefore, the probability that a sample of 90 test takers will provide a sample mean test score within 10 points of the population mean of 502 is approximately [tex]{0.6578} \).[/tex]
The perimeter of a rectangular garden is 90 meters. the length is 6 meters longer than twice the width. find the dimensions of the garden.
The width of the rectangular garden is 13 meters and the length is 32 meters.
Explanation:The problem pertains to perimeter of a rectangle, which is calculated by the formula 2*(length + width). You're told the perimeter is 90 meters, and that the length is 6 meters longer than twice the width.
So, let's denote the width as x. Then the length would be 2x + 6.
Substitute these expressions into the perimeter formula: 2*(x + 2x + 6) = 90. Simplifying this equation gives us 6x + 12 = 90.
Subtract 12 from both sides of the equation to get 6x = 78. Finally, divide each side by 6 to solve for x, which results in x = 13.
Since x represents the width of the rectangular garden, the width is 13 meters. The length, which is twice the width plus 6, is 2*13 + 6 = 32 meters.

two crooks rob a bank and flee to the east at 66mph. in 30 minutes, the police follow them in a helicopter, flying 132mph. how long will it take for police to overtake the robbers?
To calculate this, firstly we need the initial lead of the robbers in miles before the police starts to chase, which is the product of the speed of the robbers and the time before the police starts to chase. Given that the speed of robbers is 66 mph and the time before the police chase is 0.5 hours, multiplying these gives a robber lead of 33 miles.
Next, to determine how quickly the police can close this gap, we need to calculate the relative speed of the police helicopter compared to the robbers. The speed of the police is 132 mph and the speed of the robbers is 66 mph, the difference between these two speeds is the relative speed. So, 132 mph - 66 mph gives a relative speed of 66 mph.
Finally, the time it will take for the police to catch up to the robbers - the catchup time - is the ratio of the initial lead of the robbers to the relative speed of the police. Here it is 33 miles divided by 66 mph, this yields a catchup time of 0.5 hours.
Therefore, it will take the police 0.5 hours to overtake the robbers.
