Answer:
A and D
Step-by-step explanation:
I guess it depends on what kind of math you're doing but in general I would say these two at least. No matter what kind of math you're doing you should always double check your answer and make sure it has the correct units with it.

If it is about 240 miles to the International Space Station, how many kilometers is 240 miles? Round your answer to the nearest whole kilometer. Press enter to interact with the item, and press tab button or down arrow until reaching the Submit button once the item is selected A388 kilometers B385 kilometers C387 kilometers D386 kilometers
Km = miles x 1.609
240 x 1.609 = 386.24 km
The answer is D. 386 kilometers
Answer:
D. 386
Step-by-step explanation:
If we know that we have 240 miles then we need to find the Km/m which is 1.60934 Km to 1 M, and we have the equation y= 1.60934(x), y bing the total amount of Km, or in other words, your answers, and x is the miles. Now change that x into 240 so now you have y= 1.60934(240) which comes out to 386.2416 Km or 386Km as seeing you have to round tho the nearest whole number.

A ladder is leaning against a house. The distance to the house's edge from the bottom step is 3 ft. and the distance from the edge to the top step is 4 ft. What is the slant of the ladder?
Answer:
The slant of the ladder is 5 ft
Step-by-step explanation:
Look at the attached figure to understand this situation
∵ a represents the distance from the edge to the top step
∵ The distance from the edge to the top step is 4 ft
∴ a = 4 ft
∵ b represents the distance to the house's edge from the bottom step
∵ The distance to the house's edge from the bottom step is 3 ft
∴ b = 3 ft
∵ c represents the slant of the ladder
∴ We need to find c
→ By using the Pythagoras Theorem
∵ c = [tex]\sqrt{a^{2}+b^{2}}[/tex]
∴ c = [tex]\sqrt{(4)^{2}+(3)^{2}}=\sqrt{16+9}=\sqrt{25}[/tex]
∵ [tex]\sqrt{25}[/tex] = 5
∴ c = 5 ft
∴ The slant of the ladder is 5 ft

Answer:
z = 3[tex]\sqrt{13}[/tex]
Step-by-step explanation:
Using the altitude- on- hypotenuse theorem
( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
z² = 9 × (9 + 4) = 9 × 13 = 117 ( take square root of both sides )
z = [tex]\sqrt{117}[/tex]
= [tex]\sqrt{9(13)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{13}[/tex]
= 3[tex]\sqrt{13}[/tex]
Salvador’s investment of $2,200 in the stock market earned $528 in two years. Find the simple interest rate for this investment.
Answer:
24%Step-by-step explanation:
Step one:
given data
Principal= $2,200
SImple interest =$528
Time = 2years
Rate = ?
Required:
Rate R
The simple interest is expressed mathematically as
SI=PRT/100
substitute we have
528=2200*R*2/100
cross multiply
528*100=2200R
divide both sides by 2200
R=52800/2200
R=24%

answer the question for n
Answer:
el pepe
Step-by-step explanation:
The table shows the temperature (y) at different altitudes (x).
This is a linear relationship. (Example 2)
2)Find the slope of this relationship
3)Find the y-intercept for this relationship
4)Write an equation in slop intercept form that represents this relationship
5)Use the equation to determine the temperature at an altitude of 5000 feet
Answer/Step-by-step explanation:
2. Using two pairs of values, (0, 59) and (2,000, 51),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{51 - 59}{2,000 - 0} = \frac{-8}{2,000} = -\frac{1}{250} [/tex]
3. The y-intercept is the value of y when x = 0. Thus, x = 0, when y = 59. Therefore,
y-intercept (b) = 59
4. To write an equation in slope-intercept form, simply substitute m = -¹/250, and b = 59, in [tex] y = mx + b [/tex]
✅[tex] y = -\frac{1}{250}x + 59 [/tex]
5. Substitute x = 5,000 in [tex] y = -\frac{1}{250}x + 59 [/tex].
[tex] y = -\frac{1}{250}(5,000) + 59 [/tex]
[tex] y = -20 + 59 [/tex]
[tex] y = 39 [/tex]
At an altitude of 5,000 ft, temperature would be 39°F
Cindy did an experiment. She started out with 600 bacteria cells. She found that the growth rate of the bacteria cells was 4.1%. Create an equation for the situation that would work for any time, x.
Pls Help thx
Answer: P(t) = 600*(1.041)^t.
Step-by-step explanation:
An exponential growth can be written as:
P(t) = A*(1 + r)^t
Where:
A = initial population = 600
r = rate of growth in decimals = 4.1%/100% = 0.041.
t = number of units of time.
Now we have a problem, we know that the growth rate is 4.1 %, but we do not know in which time units are we working.
Because is not the same if the bacteria grows a 4.1% in one day, than if the bacteria grows a 4.1% in a hour.
But that does not matter for the actual equation, because we can just define "t" as the time (like the question asks) and the equation will be:
P(t) = 600*(1 + 0.041)^t
P(t) = 600*(1.041)^t.

At a homecoming game, there are 630 students and 1080 alumni in attendance. Express the
ratio of students to alumni as a fraction in simplest form. Explain its meaning,
Answer:
7/12
There are 7 students for every 12 alumni
Step-by-step explanation:
So, the ratio of students to alumni is 630/1080. This means there are 630 students for every 1080 alumni.
However, we can simplify this. If you treat this like a fraction and simplify, it will be much easier. Both numerator and denominator can be divided by 90, so that's what we'll do. 630/90 is 7. 1080/90 is 12.
Therefore, the correct answer is 7/12!
Hope I helped!!!!!!

Answer:
x intercept: (-1/7, 0) or (.14, 0)
y intercept: (0, 1/4) or (0, .25)
Step-by-step explanation:
Answer:
x- (−0.142857142857143,0)
y- (0, .25)
Step-by-step explanation:
The x-intercept:
Plug y=0 into the equation and solve the resulting equation 7x−5=−6 for x
(−1/7,0) = (−0.142857142857143,0)
The y-intercept:
Plug x=0 into the equation and solve the resulting equation −5=4y−6 for y
(0,1/4) = (0, .25)

Answer: y=−x+3
Step-by-step explanation: the line starts from top left between - 8 and -6 and goes through right under 4 / half a square intercepts on the x axis right onto the 4 and to the part stopping between - 8 and -6 once again, so it basically goes diagonal just be sure to make those marks
A tower is 234 meters tall. Jaylon is looking up at the top of the tower and thinking it would be cool to string a zip line from the top of the tower to a platform that is 1.9 meters high. If the angle formed between the zip line and tower would be 76 degrees how many meters of the line is neded?
Answer:
A length of 959.401 meters is needed for the zip line is needed to string it from the top of the tower to the platform.
Step-by-step explanation:
The geometrical representation of the statement is summarized in the figure below attached. The length of the line is represented by hypotenuse of the right triangle, whose value is calculated by the help of trigonometrical relations:
[tex]\cos \alpha = \frac{h}{r}[/tex] (1)
Where:
[tex]\alpha[/tex] - Angle formed between the zip line and the tower, measured in sexagesimal degrees.
[tex]h[/tex] - Vertical distance between the tower and the platform, measured in meters.
[tex]r[/tex] - Length of the zip line, measured in meters.
If we know that [tex]\alpha = 76^{\circ}[/tex] and [tex]h = 232.1\,m[/tex], then the length of the zip line is:
[tex]r = \frac{h}{\cos \alpha}[/tex]
[tex]r = \frac{232.1\,m}{\cos 76^{\circ}}[/tex]
[tex]r = 959.401\,m[/tex]
A length of 959.401 meters is needed for the zip line is needed to string it from the top of the tower to the platform.
