Are u asking what 10 +19 is its 29
Help?? Please please
Answer:
................................
Answer:
23
Solving steps
We know x= -10-15y, so we can subtract it to the equation above
x = -10-15y
2x+5y=35
2(-10-15y) + 5y = 35
(Refer to the 1st image to solve for y)
Y = -11/5
We now know y= -11/5, so we can subtract it to the equation for x.
Y = -11/5
x = -10-15y
x = -10-15(-11/5)
(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)
x = 33 - 10
x = 23

You ride through some wet paint on your bike, creating a red
spot on the tire. Write a cosine equation to model the height
of the red spot over the distance you ride.
• Your bike tire has a radius (r) of 13 inches
• The period is the circumference of the tire (2 πr)
• Start the cycle when the spot is at the top of the tire
Answer:B
y=13cos(1/13x)+13
Step-by-step explanation:
The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.
What is a cosine Function?It is a function that repeats itself in a particular time interval.
You ride through some wet paint on your bike, creating a red spot on the tire.
Write a cosine equation to model the height of the red spot over the distance you ride.
Your bike tire has a radius (r) of 13 inches.
The period is the circumference of the tire (2πr).
The cosine equation is given as
y = A cos (Bx + C) + D
Where
A = the amplitude
B = time period
C = phase difference
D = shifting of central line
Then we have the diagram
A = 13
B = 1/13
C = 0
D = 13
Then the equation will be
[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]

Which algebraic expression represents “the quotient of 7 and a number”?
Answer: D
Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Answer:
The surface area is 286.5in.
Step-by-step explanation:
7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles
7.5 * 3 = 22.5 for little rectangle
11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles
7.5 * 3 = 22.5 for the smallest rectangle
22.5 + 69 + 22.5 + 172.5 = 286.5 in SA
express -32/243 into power notation
This problem can take a while if you cannot observer the answer quickly.
First of all we can see that 32=2*2*2*2*2=2^5
243, if you don't know its actually is 3^5
Now we can see that this turns into...
- 2^5/3^5
since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below
(-3)^2=9 Positive
(-3)^3=-27 Negative since its to the odd power it keeps the sign.
This problem can be simplified to.
(-2/3)^5
And this is the answer :D

The heights of young American women, in inches, are approximately Normally distributed with mean μ and standard deviation σ = 2.4. If I want to construct a 99% confidence interval with a margin of error of no more than ± 1 inch, what is the smallest sample I can select?
The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.
The margin of error (E) for a confidence interval is described as:
E = z × (σ / √n)
where:
E is the desired margin of error
z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)
σ is the population standard deviation
n is the sample size
In this case, the margin of error is no more than ±1 inch, so E = 1 inch.
Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.
For a 99% confidence level, the z-score is approximately 2.576.
Plugging in the known values into the margin of error formula,
1 = 2.576 × (2.4 / √n)
To solve for n, rearrange the formula as follows:
√n = (2.576 × 2.4) / 1
√n = 6.1824
n = (6.1824)²
n ≈ 38.16
Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.
