In ΔABC, the measure of ∠C=90°, BA = 41, CB = 40, and AC = 9. What ratio represents the cosine of ∠B?

Answers

Answer:

40/41

Step-by-step explanation:

From the given diagram;

BA is the hypotenuse = 41

AC is the opposite = 9

CB is the adjacent = 40

Cos<B = adjaccent/hyp

Cos<B = CB/BA

Cos<B = 40/41

Hence the required ratio is 40/41

The dimensions of two square pyramids formed of sand are shown. How much more sand is in the pyramid with the greater volume?

Answers

Answer:

Answer: There is 32in² more sand in the pyramid with greater volume.

step explanation:

There are 27 more cubic inches of sand in the pyramid with the greater volume.

Explanation:
Volume of first pyramid = 1/3 x 11 x 11 x 9 = 363 in3
Volume of second pyramid = 1/3 x 12 x 12 x 7 = 336 in3
Difference = 363 - 336 = 27 in3

Answers

Answer:

The 4th one is the least so you would put that as the first one, then the 2nd one, then the 1st one, then the 3rd one.

Step-by-step explanation:

The fourth one is first because 10 to the power of 0 is 0 times 10 to the power of 1 is still 0 minus 1 to the power of 10 is 1 so 0 minus 1 is -1. The second one is second because 10 to the power of 0 times 10 to the power of 1 is 0, times 1 to the power of 10 is still 0. The first one is third in line because 10 to the power of 0 plus 10 to the power of 1 is 10 times 1 to the power of 10 is 10. The third one is last because its the greatist, 10 to the power of 0 plus 10 to the power of 1 is 10 plus 1 to the power of 10 is 11.

Help please thank you I have 1 more question-after this sorry for all the questions

Answers

Answer:

A - 6 units from the y axis. B - 5 units form the x axis. C - 8 units from T to V.

Step-by-step explanation:

So lets go over each question.

A asks for how many units point W is from the y axis. The y axis is the vertical line that goes up and down in the middle of the graph. This line is at x=0.

So we can think of the units between W and the y axis as the distance between W's x coordinates and 0.

In this case, we can see W's x coordinate is at 6.

So this means that W is 6 units from the y axis.

Next we have the distance between the x axis and point U.

The x axis is the line that goes left to right, and is at y=0.

We need to look at the y coordinate of U to find the difference between y=0 and U.

We can see that U is at y=5 on the graph.

So U is 5 units from the x axis.

The last question is the distance between point V and T.

We can see that the x coordinate for both points is x=2.

However, their y coordinates are different.

To find the difference, subtract the y coordinate of one point from the other.

In this case, the y coordinate of V is 5. The y coordinate of T is -3.

So lets see:

v-t=difference of y.

Plug in the values:

5--3

And since the negative sign and the minus sign cancel out:

5+3

=

8

So the difference in y is 8!

Phoebe invested $5800 and after one year the investment was worth $6100. How much interest did she receive?

Answers

Answer:

Amount of interest received by Phoebe = $300

Step-by-step explanation:

Given:

Amount Phoebe invested = $5,800

Amount Phoebe received after one year = $6,100

Find:

Amount of interest received by Phoebe

Computation:

Amount of interest received by Phoebe = Amount Phoebe received after one year - Amount Phoebe invested

Amount of interest received by Phoebe = 6,100 - 5,800

Amount of interest received by Phoebe = $300

Ali earns $80 in 10 hours. How long would it take him to earn $200?

Answers

Answer:

25 hours

Step-by-step explanation:

first you ask yourself that :

if it takes just 10 hrs to make $80 , would it take more or less hours to make $200.

The answer is it will take more hours to make $200,

Based on this idea established: we say if it's giving more then less would divide.

so therefore:

we have

[tex] \frac{200}{80} \times 10 [/tex]

finally we have 25 hours.

Answers

Answer:

foreign stamps = 299

US stamps = 353

Let number of foreign stamps be x.

Given she has 54 more U.S stamps than foreign , US stamps = x +54

Total stamps = US + Foreign

652 = x + 54 + x

652 - 54 = 2x

The largest jaw breaker in a store is spherical with a radius of 2 in, and sells for $4.00. A
store wants to make a 6 in. radius jaw breaker. How much should they charge for this
foot long jaw breaker?

Answers

Answer:

$36

Step-by-step explanation:

1. Determine the surface area of the  largest jaw breaker

Surface area of a sphere = 4πr²

4 x 3.14 x 2² = 50.24in²

2. Determine the surface area of the new jaw breaker

4 x 3.14 x 6² = 452.16 in²

3. Determine the cost per area

4/ 50.24

4. Determine the price for the new jaw breaker

4/ 50.24 x 452.16 = $36

Part A The measure of ∠AFC is 120°, and the measure of ∠BFC is 95°. Which equation can you use to find the measure of ∠AFB? 120° + 95° = x 120° – 95° = x 120° + x = 95° x – 120° = 95°

Answers

Answer:

x = 120-95

Step-by-step explanation:

The correct equation for the expression is:

∠AFC = ∠AFB+ ∠BFC

Given that

∠AFC = 120°

∠BFC = 95°

Substitute

120= ∠AFB+95

∠AFB = 120-95

If ∠AFB = x

The required equation will be:

x = 120-95
