Write an equation to match this graph.
Answer:
y=5x
Step-by-step explanation:
We can write this in slop-intercept form
Find the slope, rise/run = 10/2 = 5. So our slope is 5
Find the y-intercept which is 0
y=5x+0 or y=5x
Check it by plugging in a y value or x value
lets says we plugin 15, 15=5x and x=3
By looking at the graph we can see that it works

MODELING REAL LIFE A softball has a volume of about 29 cubic inches. Find the radius of the softball. Round your answer to the nearest tenth.
The radius of the softball is about___inches.
the equation for volume is V=4/3 * pi * radius cubed.
Since we know 29 is the volume, the equation is 29=4/3 * pi * radius cubed.
To get the radius alone, first divide 29 by 4/3. You get 21 3/4 or 87/4 or 21.75 (whichever way).
Then divide 21.75 by pi (3.14). You get 6.92675159236
To get the radius alone, find the cubed root of 6.92675159236.
The answer is 1.90623543217, but I'd rounded to 1.91
Answer: 1.91
Step-by-step explanation: the equation for volume is V=4/3 * pi * radius cubed.
Since we know 29 is the volume, the equation is 29=4/3 * pi * radius cubed.
To get the radius alone, first, divide 29 by 4/3. You get 21 3/4 or 87/4 or 21.75 (whichever way).
Then divide 21.75 by pi (3.14). You get 6.92675159236
To get the radius alone, find the cubed root of 6.92675159236.
The answer is 1.90623543217, but I rounded it to 1.91

Divide the minutes by 2 since 6 is half of 12.Half of 1 is .5 or [tex]\frac{1}{2}[/tex]Half of 6 is 3Half of 17 is 8.5If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
Step-by-step explanation:
Pages is directly proportional to Minutes
P = KM
k = P/M
when P = 6, M = 12.
k = 6/12
k = 0.5
_____________________
when M = 1
P = Km
P = 0.5×1 = 0.5
P = half a page.
______________________
when M = 6
P = 0.5× 6
P = 3 pages
______________________
when M = 17
P = 0.5×17 = 8.5
P = 8 and half pages

x = number of minutes for fruit cans
y = number of minutes for vegetable cans
Which of the linear equations expresses the situation?
3x + 8y = 384
24x + 64y = 384
64x + 24y = 384
24x + 64y + 384 = 0

The fractions 1/2 and 3/5 are terminating decimals. The fractions 1/3 and 1/7 are repeating decimals.
Without using a calculator, how can you determine in a fraction will repeat or terminate? Give an additional example of a fraction that repeats.
Step-by-step explanation:
A terminating decimal is a decimal that doesnt repeat, it just stops. A repeating decimal is a decimal that goes on forever, it never stops.
Answer:
To determine if a fraction will repeat or terminate, first you need to turn it into a decimal, then you can see if it repeats or terminates.
An example of a fraction that repeats is 1/3

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 4 = 4. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - four minus one quarter = fifteen quarters.

Given: KLMN is a parallelogram, LF is perpendicular to KN, LD is perpendicular to NM, angle FLD = 35. Find angles of KLMN
The question is four parts, It is required the angles of parallelogram KLMN
So, It is required ⇒ ∠K , ∠L , ∠M and ∠N
See the attached figure which represents the explanation of the problem
========================
Part (1): Find ∠N:
==============
in the shape FLDN
∵ LF ⊥ KN ⇒⇒⇒ ∴ ∠LFN = 90°
∵ LD ⊥ NM ⇒⇒⇒ ∴ ∠LDN = 90°
∵ The sum of all angels of FLDN = 360°
∵ ∠FLD = 35°
∴ ∠FLD + ∠LDN + ∠DNF + ∠LFN = 360°
∴ 35° + 90° + ∠DNF + 90° = 360°
∴ ∠DNF = 360° - ( 90° + 90° + 35°) = 360° - 215° = 145°
∴ The measure of angle N = 145°
=============================
Part (2): Find ∠M:
==============
∵ KLMN is parallelogram , ∠N = 145°
∴ The angles N and M are supplementary angles ⇒ property of the parallelogram
∴ ∠M + ∠N = 180°
∴ ∠M = 180° - ∠N = 180° - 145° = 35°
∴ The measure of angle M = 35°
================================
Part (3): Find ∠L:
==============
∵ KLMN is parallelogram , ∠M = 35°
∴ The angles N and M are supplementary angles ⇒ property of the parallelogram
∴ ∠M + ∠KLM = 180°
∴ ∠KLM = 180° - ∠M = 180° - 35° = 145°
OR ∠KLM = ∠N = 145° ⇒⇒⇒ property of the parallelogram
∴ The measure of angle KLM = 145°
===================================
Part (4): Find ∠K:
==============∵ KLMN is parallelogram , ∠N = 35°
∴ The angles N and M are supplementary angles ⇒ property of the parallelogram
∴ ∠K + ∠N = 180°
∴ ∠K = 180° - ∠N = 180° - 145° = 35°
OR ∠K = ∠M = 35° ⇒⇒⇒ property of the parallelogram
∴ The measure of angle K = 35°
Answer:
m∠K= 35°, m∠KLM= 145°, m∠M= 35°, m∠N = 145°

Jenna’s method: Mia’s method:
5(30 + 4) 5(30 + 4)
(5)(30) + (5)(4) 5(34) = 170
150 + 20 = 170
Explain why both Jenna and Mia arrived at the same answer and the advantage of one method over the other.
Answer:
Jenna and Mia both used the distributive property to solve the problem, and the advantage of using Mia's method was that she added whats was I the parentheses, which narrowed down the math, but was still longer than Jenna's, as Jenna just multiplied both parts then added, making it shorter, and easier.

what is lim x → -1 ln x
Answer:
Step-by-step explanation:
ln(∞) = ?
Since infinity is not a number, we should use limits:
x approaches infinity
The limit of the natural logarithm of x when x approaches infinity is infinity:
lim ln(x) = ∞
x→∞
x approaches minus infinity
The opposite case, the natural logarithm of minus infinity is undefined for real numbers, since the natural logarithm function is undefined for negative numbers:
lim ln(x) is undefined
x → -∞
So we can summarize
ln(∞) = ∞

Answer:
[tex]7[/tex]
Step-by-step explanation:
Use the Pythagorean Theorem
[tex]a^2 + b^2 = c^2[/tex]
[tex]a[/tex] and [tex]b[/tex] are either opposite or adjacent
[tex]c[/tex] is the hypotenuse.
1. Look for the right angle. (the little box). The right angle "points" to the hypotenuse. In this case, the hypotenuse is 25.
2. Because we know the hypotenuse is 25. We know that 24 is our adjacent. Meaning our missing side is the opposite.
3. Plug in the numbers. [tex]24^2 + b^2 = 25^2[/tex]
4. Solve:
[tex]24^2 + b^2 = 25^2[/tex]
[tex]576 +b^2=625[/tex]
[tex]b^2 = 625-576[/tex]
[tex]b^2 = 49[/tex]
[tex]\sqrt{b^2} = \sqrt{49}[/tex]
[tex]b = 7[/tex]

The following data points represent last year’s revenue (in thousands of dollars) for each Herman Huagoes location
Answer:
142
Step-by-step explanation:
Since the median is defined as the data point that separates the lower half from the upper half.
Odd # data points: Middle value of an ordered pair with an equal amount of data points on both sides.Even # data points: Average of two middle values in an ordered pair with an equal amount of data points on both sides.Since there is an even amount of data points, to find the median, identify the two middle values, which are 137 and 147. Then add them together and divide by 2 to compute the average →
137 + 147 / 2 → 284 / 2 → 142.
Thus the median revenue is
142 thousand dollars
A local store buys video games from the manufacturer for $15.99. They mark up the price of the game 250%. What is the selling price of the video game? Round your answer to the nearest cent.
The answer for the above question wherein we are given the cost price and mark up price and we have to find the selling price is $39.98 after rounding it to the nearest cents.
The method of calculation for the same computation is as follows:
Firstly, the cost price of the video game is $15.99.
Second, the merchant is 250% overcharged for the game. Therefore, we would have to calculate the 250% of $15.99 as it would give us the selling price. We are making use of the following formula Selling price = markup price/100 × Cost price. Applying this formula we would get the following solution:
$15.99 × 250/100 = $ 39.975.
Rounding to the nearest cents we would get our final answer as $39.98. Hence, the selling price of the video game is $39.98.
