The measures of the legs of a right triangle both measure 7 yards. What is the length of the hypotenuse? Round your answer to the nearest tenth.
A. 7 yards
B. 9.8 yards
C. 9.9 yards
D. 10 yards
Answer: 9.9 yards
Step-by-step explanation: Since we know that the legs of the right triangle both measure 7 yards, we can use the Pythagorean theorem to find the length of the hypotenuse, which is the longest side of the right triangle.
According to the Pythagorean theorem, the square of the hypotenuse equals the sum of the squares of the legs. In this case, we have:
c^2 = 7^2 + 7^2 c^2 = 49 + 49 c^2 = 98
To find the length of the hypotenuse, we need to take the square root of both sides of the equation:
c = √98
Using a calculator, we can find that √98 is approximately 9.9. Therefore, the length of the hypotenuse is approximately 9.9 yards.
The answer is C. 9.9 yards.
How many yards are in two and one-half miles?
A 4,400 yards
B 4,928 yards
C 5,280 yards
D 6,160 yards
A. 4,400

One mile is equal to 1,760 yards. Therefore, two and one-half miles can be calculated as:
2.5 miles * 1,760 yards/mile = 4,400 yards
So, the answer is A) 4,400 yards.

An $800 deposit for 24 months earned $200 in interest.
SIMPLE INTEREST
NEED RATE & TOTAL VALUE
Answer:
x=12.5% (hope this right if not I am so sorry)
Answer Explanation:
let x%= annual interest rate
deposit = $800
interest earning period = 24 months = 24/12 years
interest earned = $200
so $200 = $800 * x /100* 24/12
200 = 800 * x/100 * 2
solve for x,
x = 12.5% per annum
Answer: X = 12.5%

Erin gets her exercise by running. The graph shows the distances she covers in a given amount of time. How many hours does it take for Erin to run 25 miles? Distance (miles) y 60 50 9 20 10 0 2 3 4 Time (hours) 5 X 6
Answer:
2.5 hours (2 and 1/2)
Step-by-step explanation:
Every 1 hour, Erin runs 10 miles and so on. The ratio is 1:10 (2:20, 3:30, etc.) 25 is 20+5, and 5 is considered 1/2 of 10, so it would count as 0.5 (or 1/2). So in 2.5 hours Erin will run 25 miles. Hope it helped :>
Can someone answer this please?????
Answer: y=-7
Step-by-step explanation:
solve 5x+2y =-4 for x
Add -2y to both sides
divide both sides by five
substitue -2/5y +-4/5 for x in 3X +10 Y equals -64
44/5 + -12/5 equals -64
Simply both sides
add 12/5 to both sides
Divided by 44/5
y= -7
Answer:
Hence The Value of Y=-2 at the intersecting point
Step-by-step explanation:
Given the equation
5x+2y=-4 and 3x+10y=-64
are intersected at X=2 to find the value of y
solution the equation 5x+2y=-4 and 3x+10y=-64
are intersect at x=2 means x=2 satisfied both equations so x=2 put in the
1st equation
5 x 2+2y=-4
2y=-4 -1 0= -14
y= -7

What is the sum of -2x³ + x-3 and x³ - 3x - 4?
(a) Show your work.
(b) Is the sum of -2x³ + x-3 and x³ - 3x - 4 equal to the sum of x³ - 3x - 4 and
-2x³ + x-3? Explain your answer.
Answer:
Step-by-step explanation
For the first sum you nee to find the same coefficient or add or subtract a number
[tex]-x^3 -2x -7[/tex]
This the simplified version of the sum above. I have basically subtracted -2x^3 by x^3 to make -x^3. Then I have subtracted -3x and x to make -2x. Finally I have added -4 and -3 as the rule suggests to add two numerals the minus symbol on both of them.
The next sum we have to simplify both numerals so we know if both sum’s answer are
[tex]-x^3 -2x -7-x^3 -2x -7[/tex]
After simplifying them, both of them have the same answer, so the statement is true. To explain this, we could say that the sums were basically rotated around to trick us but the answer is still the same

Calculate the volume of a cone with a height of 6 inches and a diameter of 6 inches.
Leave your answer in terms of PI
Answer: Volume ≈ 56.55
Step-by-step explanation:
56.54867 is the answer, but I rounded it. I hope this helped! :)
Answer:
18π cubic inches
Step-by-step explanation:
First, we need to find the radius of the cone, which is half of the diameter.
radius = diameter/2 = 6/2 = 3 inches
The formula for the volume of a cone is:
V = 1/3 × π × r^2 × h
where r is the radius of the base of the cone, and h is the height of the cone.
Substituting the values we get:
V = 1/3 × π × 3^2 × 6
V = 1/3 × π × 9 × 6
V = π × 18
A map is designed with a scale of 2 inch for every 10 miles. If the distance between two towns is 5 inches on the map, how far apart are they?
Answer: 25 miles
Step-by-step explanation:
Answer:
The answer is 25.
Step-by-step explanation:
Since the scale shows 10 miles for every 2 inches, you can easily figure out that it is 5 miles per inch.
Now, it says two towns are 5 inches apart. With the previous information, you can either multiply 5 inches by 5 miles per inch or think deeper.
Thinking deeper: If there is 4 inches, that is 20 miles. Adding another inch doesn’t add another ten. It adds half of ten and half of ten in 5. 20+5=25
The variables x and y have a proportional relationship, and y=5 when x=8
Which equation represents this relationship
A- y=8/5x
B- y=13x
C- y=5/8x
D- y=40x
Answer:
C y = 5/8 x
Step-by-step explanation:
y = kx
5 = k × 8
k = 5/8
y = (5/8)x
You can read. Now help me out :(
Answer: incorrect i cannot read.
anyways, the answer is c, the third bubble.
and 20 minutes
you get this from needing to find the total minutes spent, in order to do so, you need to add 25, to whatever number (or t) to equal 45
as for the minutes, you do the exact opposite, and subtract 25 from 45, to get 20

Solve the equation using inverse operations. Check your solutions. In you final answer, include all of your work
-X²= - 36
On a chapter test, Stephanie uses the rules of equation solving and inverse operations to solve the cubic equation below. The directions on the test are not very specific; however, they do say to give an exact solution. Stephanie is not sure if she should submit a decimal approximation or a simplified radical as the answer.
4x³=756
What recommendation can you make to Stephanie regarding her answer to the cubic equation above? In your recommendation, explain what the term "exact" indicates with regards to the solution.
Solve the cubic equation from Stephanie’s test. Submit two solutions for the equation- a) your answer as a decimal approximation, rounded to the nearest hundredth, and b) as a simplified radical. Use substitution to check each version of your solution in the original equation.
After solving the test question and checking both the decimal solution and the simplified radical form, would you change your recommendation (in Part 1) to Stephanie regarding the format of her answer? Use complete sentences to explain your reasoning.
Answer: The answer is -6.
Step-by-step explanation:
The first step in solving -X²= - 36 is to simplify the expression. Then, divide both sides by the same factor. You'll get X² - 36 = 0.
After that, you need to use the quadratic formula. Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula. a=1, b=0, and c=-36.
Finally, you need to simplify the expression. First, evaluate the exponent. Then multiply the numbers. After that, Add the numbers and evaluate the square root. Add zero, and then multiply the numbers again. You get +12/2, which simplifies into X = 6. Add the negative, and you get X = -6.

1.) 25 - 3x = 88
2.) -11 = 7 - x
3.) 95 = -4 + 33x
Answer: hope this helps ♡
1.) x = -21
2.) x = 18
3.) x = 3
Step-by-step explanation:
(minus&minus = plus) (minus&plus = minus) (plus&minus = minus)
1.) 25 - 3x = 88
25 - 25 - 3x = 88 - 25
-3x = 63
-3x ÷ 3 = 63 ÷ 3
-x = 21 → x = -21
2.) -11 = 7 - x
-11 - 7 = 7 -7 -x
-18 = -x
18 = x → x = 18
3.) 95 = -4 + 33x
95 + 4 = -4 + 4 + 33x
99 = 33x
99 ÷ 33 = 33x ÷ 33
3 = x → x = 3

Answer:
3 times more
Step-by-step explanation:
mangos: m = 108
portugals: p
oranges: o = 3p
108 + p + 3p = 540
108 + 4p = 540
4p = 540-108 = 432
p = 432/4 = 108
o = 3p = 3(108) = 324
324/108 = 3 there are 3 times more oranges than portugals
Answer:
1620
Step-by-step explanation:
540 X 3 = 1620

Infinitely many.
The two equations are the same yet formatted differently. Because these lines will overlap each other, the answer is infinitely many.
