Answer:
The answer is b: 25
Note however that the shape of the diagram does not match the numbers on it. So either it is poorly drawn, or I am misinterpreting the numbers. It seems pretty clear though that the image is incorrect, as the two segments both marked as being 25 units long are represented at different lengths.
Step-by-step explanation:
The image here does not fit the numbers. Note that the bottom triangle has two sides with given lengths of 25 units, but they are drawn as different lengths.
Let's plough on though, and find a better image of what that shape would be.
Starting with the bottom triangle:
Given that the two sides of the bottom triangle are both 25 units in length, we know that it is an isosceles triangle (despite its depiction otherwise). Because of that, we know that the two bottom angles are equal. We already know that the top corner is 90°, and that the sum of the angles in a triangle must be 180° This means that the two bottom angles (again, contrary to how its drawn) are both equal to 45°
Now that we have that information, we can look at the over triangle. We know that the bottom right corner is 45°, and that the bottom left is 90°. That tells us that the top angle is also 45°.
With that said, we can redraw the image with the proper proportions. See the attached image.
That very much simplifies things. The line separating the triangles bisects the hypotenuse of the larger triangle, meaning that x is also equal to 25.
To be sure of that though, we can prove it another way. Given that the bottom two corners are both 45, we can use the sine rule to measure x. The sine rule states that the sine of each angle in a triangle has the same ratio to their opposite sides. Usually expressed as:
[tex]\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}[/tex]
where a, b and c are the side lengths, and A, B and C are the angles of the corners opposite those sides.
With that we can take the two parts of the overall triangle's hypotenuse, 25 and x, and say that each of those divided by the sine of the angle opposite them is equal to each other:
[tex]\frac{x}{\sin 45} = \frac{25}{\sin 45}[/tex]
This turns out to be very easy to solve, as both sides have the same denominator. As a result, we can just multiply both sides by sin 45, giving us:
x = 25.
A train travels 5 miles in 12 minutes at this rate how far will go in two hours
Answer:
Well, 60 (minutes in an hour) divided by 12 (from the problem) is 5, so you have to multiply that 5 by the 5 from the problem to find that the train is going 25 (5*5) mph. Just double this for two hours, and you result in 50!

The Problem: Phillips Health and Beauty Spa is replacing one of its workstations. The interest on a loan secured by the spa was $93.50. The money was borrowed at 5.5% simple interest for 2 years. What was the amount that they borrowed?
Answer:
$850
Step-by-step explanation:
Amount that was borrowed = interest / (interest rate x time)
93.50 / (0.055 x 2) =
93.50 / 0.11 = $850

Answer:
1) 4
2) 5
3) -23
4) 8
5) 7
6) -64
7) -10
8) 19
9) 9
10) -56
Answer:
1) = -4
2) = 5
3) = 17
4) = 8
5) = 7
6) = -64
7) = -10
8) = 19
9) = 9
10) = -56
Step-by-step explanation:
1) (-4 + 2)^2 = -2^2 = -4
2) 25 / (9 - 4) = 25 / 5 = 5
3) 4 * 5 - 3 = 20 - 3 = 17
4) 2(2 + 2) = 2 * 4 = 8
5) (-10 + 5) / 5 + 8 = -5 / 5 + 8 = -1 + 8 = 7
6) (-3 - 1)^3 = -4^3 = -64
7) 5(5 - 7) = 5 * -2 = -10
8) 2 * 7 + 5 = 14 + 5 = 19
9) (5 * 3 + 3) / 2 = (15 + 3) / 2 = 18 / 2 = 9
10) 8(-1 - 6) = 8 * -7 = -56

Dilate Point B by a scale factor of 1/2
Answer:
( -1.5 , 1 )
Step-by-step explanation:
Hello There!
When dilating a point we divide or multiply the coordinates by whatever the scale factor is
Because the scale factor is 1/2 we just have to divide the coordinates of point B by 2
Preimage coordinates - ( -3 , 2 )
-3/2=-1.5 or -3/5
2/2=1
Dilated image coordinates ( -1.5 , 1 )

1) James deposited $4,000 into an account. He made
no additional deposits or withdrawals. James earned
5.75% annual simple interest on the money in the
account.
What was the balance in dollars and cents in James
account at the end of 5 years?
Answer:
$5150
Step-by-step explanation:
Given data
Principal=$4000
Rate=5.75%
Time= 5 years
The expression for the balance on simple interest is
A=P(1+rt)
substitute
A=4000(1+0.0575*5)
A=4000(1+0.2875)
A=4000X(1.2875)
A=$5150
Hence the balance is $5150
