Answer:
31x=217 x=7
Step-by-step explanation:
begin with what you know. You know that you will have 31 days to complete the goal and that the goal is 217 miles. This gives you your y (217) and your m (31). Then set up into y=mx+b form. This gives 31x=217. Then to solve divide 217 by 31. This gives the needed the needed answer of 7 miles per day

x = 0,5 ft
y = 2 ft and
V = 2 ft³
Step-by-step explanation: See annex
c) V = y*y*x
d-1) y = 3 - 2x
d-2) V = (3-2x)* ( 3-2x)* x ⇒ V = (3-2x)²*x
V(x) =( 9 + 4x² - 12x )*x ⇒ V(x) = 9x + 4x³ - 12x²
Taking derivatives
V¨(x) = 9 + 12x² - 24x
V¨(x) = 0 ⇒ 12x² -24x +9 = 0 ⇒ 4x² - 8x + 3 = 0
Solving for x (second degree equation)
x =[ -b ± √b²- 4ac ] / 2a
we get x₁ = 1,5 and x₂ = 0,5
We look at y = 3 - 2x and see that the value x₂ is the only valid root
then
x = 0,5 ft
y = 2 ft and
V = 0,5*2*2
V = 2 ft³

A single die is rolled. Find the odds in favor of rolling a number greater than 3.
Answer:
6:3
Step-by-step explanation:
Answer and Step-by-step explanation:
3 of the options are not to be chosen, and 3 are wanted.
That means that anything above 3 (so, 4, 5, or 6) are the numbers that are wanted, while the numbers 1, 2, and 3 are not wanted.
We have 6 total options.
The ration would be:
3:6, or 3 to 6. This reduces down to 1:2, or 1 to 2.
That means that there is a 50% chance of getting 4, 5, or 6.

You spin a spinner that is equally divided into 5 parts, and then you spin it again. 1 part is pink, 2 parts are blue, and 2 parts are black. What is the probability of the spinner dropping on a blue section on the first spin and then a blue section of the second spin?
Answer:
There is a 16% chance of the spinner dropping on a blue section on the first spin and then a blue section of the second spin.
Step-by-step explanation:
Given that I spin a spinner that is equally divided into 5 parts, and then I spin it again, knowing that 1 part is pink, 2 parts are blue, and 2 parts are black, to determine what is the probability of the spinner dropping on a blue section on the first spin and then a blue section of the second spin the following calculation must be performed:
Blue parts: 2
Total Parts: 5
2/5 = 0.4 = 40%
0.40 x 0.40 = 0.16
Thus, there is a 16% chance of the spinner dropping on a blue section on the first spin and then a blue section of the second spin.
The opposite sides of a parallelogram have measures (2x+10) cin and (x+15)
cm. What is the measure of the sides?
Answer:
The measure of the sides is 20 cm.
Step-by-step explanation:
Opposite side of a parallelogram:
Opposite sides of a parallelogram are congruent, that is, they have the same measure.
Measures (2x+10) cm and (x+15) cm:
This means that:
[tex]2x + 10 = x + 15[/tex]
[tex]2x - x = 15 - 10[/tex]
[tex]x = 5[/tex]
2x + 10 = 2*5 + 10 = 10 + 10 = 20
The measure of the sides is 20 cm.

Esther estimates that she will need about $8,600 for the first year of tuition at college. Her grandparents contribution will cover 65% of the tuition expenses, and Esther will need to save to pay for the rest. If Esther has 2 years to save, what is the minimum amount that she should save each month?
Answer:
$125.42
Step-by-step explanation:
Her grandparents will cover 65% of $8600, which is 8600 * 0.65 = $5590. Therefore, she needs to pay for the part they're not covering, which is $8600 - $5590 = $3010.
2 years = 24 months, so assuming she wants to save the same amount each month, we need to divide $3010 by 24 to get the amount per month. This gets us $125.42
The minimum amount that she should save each month for two years is $125.42.
What is the minimum amount she would have to save each month?Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.
Amount given by her grandparents = 65% x 8600= $5590
Amount she would have to save each month for two years = (8600 - $5590) / 24 = $125.42

π = 22/7Diameter = 4 mexplanation :⟼ c = πd
⟼ c = 22/7 × 4 m
⟼ c = 88/7 m

A woman bought some large frames for $13 each and some small frames for $6 each at a closeout sale. If she bought 18 frames for $136, find how many of each type
she bought
She bought large frames
vie
Answer:
she bought 4 large frames and 14 small frames!
Step-by-step explanation:
This is a system of equation problem!
let's say that x= large frames and y=small frames.
since there's 18 total, we already have our first equation set.
x+y=18
(number of large frames) + (number of small frames)= 18
13x would represent the large frames because each one is 13 dollars.
6y would represent the small frames because each one is 6 dollars.
Since she paid 136 dollars total, we can already tell that
13x+6y=136
(price of large frames*number of large frames) + (price of small frames*number of small frames)=136.
Now, time for the math!
Attached below is how you would work it out using substitution.
Hope this helps!
x=4 and y=14
Meaning that she bought 4 large frames and 14 small frames!

Madeline invested $51,000 in an account paying interest rate of 6 1/8% compounded daily. Harper invested 51000 in an account paying an interest rate of 5 3/4% compounded monthly. After 13 years, how much more money would Madeline have in her account than Harper
Answer:
$5564.87
Step-by-step explanation:
We are to determine the difference between the future values of each investment
The formula for calculating future value:
FV = P (1 + r)^mn
FV = Future value
P = Present value
R = interest rate
N = number of years
m = number of compounding
Madeline
P = Present value = 51,000
R = interest rate = 0.06125 / 365 = 0.000168
N = number of years = 13
m = number of compounding = 365
51,000 x (1.000168)^4745 = 113,070.20
Harper
51,000 x (1.004792)^156 = 107,505.33
Difference = 113,070.20 - 107,505.33 = $5,564.87

On the left side of the chart, is the x values. The x values are listed on the x axis which is the horizontal line.
The right side of the chart are the y values. The y values are listed on the y axis which is the vertical line.
Knowing this, we can start
First, for all the answer that we know the x value, we need to find the number that matches on the x axis. Once we find that number, we go up or down on the y axis until we find the line.
If we know the y value, we need to find the number that matches on the y axis. Then we will go right until we find the line.
Remember - There CAN NOT be two y values for the same x value but THERE CAN BE two x values for the same y value
