Answer:
x=24
Step-by-step explanation:
Because the triangle is a 30-60-90 triangle, you can find side x, the hypotenuse, by doubling the short side 12. Therefore, x=2(12)=24.

x + 3 > 70
How do I solve this step by step?
Answer:
x > 67
Step-by-step explanation:
x+3 >70
subtract from each side
x+3-3 > 70 -3
x > 67
Algebra
To solve this, simplify the algebra inequality.
Subtract three from both sides.
x>67
Meaning, x is bigger than 67.
PLS HELP What is 4 1/3 multiplied by 2 1/4 reduced to the lowest term
5x - y = -1 - -5x + 3y = 25
Answer:
x = 101/20, y = 1/4
Step-by-step explanation:
Solve the following system:
{-y + 5 x = 25 | (equation 1)
3 y + 5 x - 1 = 25 | (equation 2)
Express the system in standard form:
{5 x - y = 25 | (equation 1)
5 x + 3 y = 26 | (equation 2)
Subtract equation 1 from equation 2:
{5 x - y = 25 | (equation 1)
0 x+4 y = 1 | (equation 2)
Divide equation 2 by 4:
{5 x - y = 25 | (equation 1)
0 x+y = 1/4 | (equation 2)
Add equation 2 to equation 1:
{5 x+0 y = 101/4 | (equation 1)
0 x+y = 1/4 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 101/20 | (equation 1)
0 x+y = 1/4 | (equation 2)
Collect results:
Answer: {x = 101/20, y = 1/4

Reasoning A cone with radius 3 and height 10 has its radius tripled. How many times
greater is the volume of the larger cone than the smaller cone? Use pencil and paper.
Explain how the volume of the cone would change if the radius were divided by three.
The volume of the larger cone is times greater than the volume of the smaller
cone.
Answer:
9 times larger and 9 times smaller (it changes by the square of the change factor of the radius).
Step-by-step explanation:
the reason :
the formula of the volume of a cone is base area times height divided by 3.
and the base area is the area of a circle with radius r.
=> Vc = pi×r²×height / 3
now, when we multiply r by a factor, like in our examples here by 3 and also by 1/3, then this factor also gets squared in the calculation of that formula.
so, if the new radius is 3×r, then the formula looks like
Vc = pi×(3r)²×height / 3 = pi×9r²×height / 3
so, as you can see, when we triple the radius, we introduce the factor 9 (square of 3) into the volume, and therefore the volume increases by the factor 9.
similar, when we divide the radius by 3
Vc = pi×(r/3)²×height / 3 = pi×(r²/9)×height / 3
we introduce the factor 1/9 into the volume, and it decreases to 1/9th of its original size.

Jack is 5 years older than Mary. In four years the sum of their age is 33 years old. What are their ages?
Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.
Which statement is not true about the data set shown? 66, 89, 90, 55, 92, 82 A.) The median ia 82 B.) The mean is 79 C.) The rante is 37 D.) There is no mode
Answer:
a
Step-by-step explanation:
Mode refers to a value that appears most frequently in a data set.
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Median is the number that occurs in the middle of a set of observations
Arranging the numbers in ascending order : 55, 66, 82, 89, 90, 92
median = (82 + 89) / 2 = 85.5
There is no mode because the numbers only appear once
Range = 92 - 55 = 37
mean = 476/6 = 79

( MULTIPLE CHOICE)
Answer:
A+6=4/5(B+6) A=B+3/4
Step-by-step explanation:
The first sack contains A, the second sack contains B.
So, A = 3/4 B
When 6 potatoes are added to each sack.
Then: A+B = 4/5 (B+6)
So, the answer is A+6=4/5(B+6) A=B+3/4
Sue’s bakery sold 850 donuts last week this week the number of donuts sold increase 12% how many more donuts were sold this week

Step-by-step explanation:
If you have anything else that has to do with donuts it goes straight to me.
Answer:
102 more donuts
Step-by-step explanation
when dealing with how much percent increase you multiply the amount by the percent in decimal form . So 850x0.12 is 102.

Put Y=x^2+10x+18 in vertex form
Answer:(-5,-7)
Step-by-step explanation:
Rewrite in Vertex form and use this form to find the vertex (h,k)
Answer:
y = (x + 5)² - 7
Step-by-step explanation:
Given
y = x² + 10x + 18
To obtain vertex form use the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² + 10x
y = x² + 2(5)x + 25 - 25 + 18
= (x + 5)² - 7 ← in vertex form
Write an equation of the line that passes
through (0, – 5) and is perpendicular to
the line y= - 4/5x
Answer:
y=5/4x-5
Step-by-step explanation:
Hi there!
The equation of the line is typically written as y=mx+b, where m is the slope and b is the y intercept
Perpendicular lines have slopes that are negative and reciprocal. If they are multiplied together, the result is -1
So let's find the slope of the perpendicular line with this formula:
-4/5m=-1
multiply both sides by -5/4 (we need to isolate m onto one side, and -4/5*-5/4=1)
m=5/4
So the slope of the new line is 5/4
Here's the equation so far:
y=5/4x+b
now we need to find b
Because the equation of the line passes through (0,-5), we can use it to solve for b
substitute 0 as x and -5 as y
-5=5/4(0)+b
-5=0+b
-5=b
Therefore the equation of the line is:
y=5/4x-5
Hope this helps!
