The measure of lengths of the legs are 7 and 24. Therefore, option C is the correct answer.

What is the Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given that, the hypotenuse of a right triangle measures 25.

A) 3²+4²= Square of the hypotenuse

25=Square of the hypotenuse

Hypotenuse=5 units

B) 5²+5²= Square of the hypotenuse

50=Square of the hypotenuse

Hypotenuse=5√2 units

C) 7²+24²= Square of the hypotenuse

625=Square of the hypotenuse

Hypotenuse=25 units

D) 10²+15²= Square of the hypotenuse

325=Square of the hypotenuse

Hypotenuse=√325 units

Therefore, option C is the correct answer.

Janelle makes a profit of 10% when she sells a bag for $900
i. What is the cost price? ii. find out how much she should have sold it for to make a profit of 15%​

Answers

Answer:

i. 818.18

ii. 940.9

Step-by-step explanation:

SP = 900

or, CP + 10% of CP = 900

or, CP + 10/100 × CP = 900

or, 110CP = 90000

or, CP = 90000/110

CP = 818.18

for profit= 15%

SP = 9000/11 + 15% of 9000/11

= 940.9

Do the following set of points represent a function?Explain your answer (2,3),(3,8),(-1,4),(1,8)

Answers

Answer:

Yes.

Step-by-step explanation:

Yes.

To have a function, you cannot use the same value for an x-coordinate more than once. Here, each value of an x-coordinate is used only once, so it is a function.

Answer:

Yes.

Step-by-step explanation:

It is a many-to-one function. Both 3 and 1 map to 8.

2 maps to to 3 and -1 maps to 4 which is one-to-one.

There are no one to many mappings  so it is a function.

Find the total surface of this cuboid

Answers

Given:

Consider the dimensions of the cuboid are 5 by 4 by 6.

To find:

The total surface of the cuboid.

Solution:

The total surface area of a cuboid is:

[tex]Area=2(lb+bh+hl)[/tex]

Where, l is length, w is width and h is the height.

Substituting l=5, b=4 and h=6, we get

[tex]Area=2(5\times 4+4\times 6+6\times 5)[/tex]

[tex]Area=2(20+24+30)[/tex]

[tex]Area=2(74)[/tex]

[tex]Area=148[/tex]

Therefore, the total surface area of the cuboid is 148 sq. units.

The graph models the value of a vehicle over x years following its purchase for $25,000.
Which interpretation is correct?
(A) The asymptote indicates that the original value of the vehicle approached $25,000

(B) The point (40, 0) contains the x-intercept

(C) The line x=25,000 is an asymptote of the graph

(D)The line y=0 is an asymptote of the graph

Answers

Answer: it’s D. I took the test

The correct  interpretation are,

The asymptote indicates that the original value of the vehicle approached $25,000

The line y=0 is an asymptote of the graph

Graph of function:

From the given graph,

It is observed that graph is never intersect the x- axis. Therefore, x-axis will be the asymptote.

The equation of x- axis is y= 0.

Since at x= 0, the value of y = 25,000 , It means that  the original value of the vehicle approached $25,000.

The x- intercept is the point where graph crosses the x-axis.

please help i suck at math and I am in class ​

Answers

Answer:84.84m^2

Edit: I redid it doing the base separate and got 84.847 because Pythagorean theorem tells you the sides of the three triangles are 6.998 which is ever so slightly smaller than the base triangle.

Step-by-step explanation:

This is assuming the triangles are equal. 1/2bh gives you 21.21 for the triangle with the given height and then multiplying that by four for all the sides gives you 84.84m^2. The question doesn’t specify what type of pyramid it is so again I’m assuming it’s equal. Not 100% positive hope it can help at all.

The formula to determine how many bags 'B' can be filled with M&M's from a stockpile of 'T', where each bag contains 39 candies, is:

B = T/39

This computation takes the sum of all M&M's in 'T' and divides it by the quantity of candies present in each sack (39), producing the amount of bags 'B' that can be filled.
