Answer:

More than 10% of Gillway students earned honors.

Step-by-step explanation:

Step 1: Find the number of students who earned honors

43 + 17 = 60

Step 2: Find the total number of students

381 + 108 = 489

Step 3: Find the percentage of students who earned honors

Students who earned honors/Total students x 100

60/489 x 100

12.27%

Step 4: Find the correct answer

Just under 11% of Gillway students earned honors.

This is incorrect since the percentage is more than 11%.

Just over 11% of Gillway students earned honors.

This is incorrect as just over 11% would mean somewhere between 11 and 12% whereas the actual percentage is just over 12%.

More than 10% of Gillway students earned honors.

This is correct as compared to all other statements since 12.27% is more than 10%.

Almost 11% of Gillway students earned honors.

This is incorrect since almost 11% means less than 11% whereas the actual percentage is more than 11%.

A taxi ride costs $3.50 plus $2.50 per mile driven. If Sasha has $37 in cash , what is the greatest whole number of miles she ca

Margaret [11]

Create an equation for the total costs of driving x miles: 3.50 + 2.50x

since Sasha has $37, the equation would become: 3.50 + 2.50x = $37

subtract 3.50 from both sides: 2.50x = 33.50

divide 2.50 on both sides: x = 13.4

since the problem is asking for the greatest whole number of miles, you have to round down and the answer would be: 13 miles.

Kevin's bank offered him a 4.5% interest rate for his mortgage. If he purchases 3 points, what will be his new rate?

erma4kov [3.2K]

Answer:

The new rate would be 3.75%

Step-by-step explanation:

Purchasing a point simply implies negotiating for a lower rate of interest, which involves paying 1% of the loan in lieu of 1% interest reduction.

A point implies a reduction in interest rate by 0.25% while 3 points would reduce the interest rate by 0.75%(0.25%*3)

New interest rate=4.5%-0.75%=3.75%

The six faces of a cube are painted black. The cube is then cut into <img src="https://tex.z-dn.net/?f=5%5E3%20%3D%20125" id="Te

Rasek [7]

Answer:

The probability that a randomly selected small cube is rolled and the face on the top is black is P=0.2.

Step-by-step explanation:

We have a cube, with the faces painted black, that each side is divided in 5, so we end up with 125 cubes.

We have to calculate the probability that a randomly selected cube is rolled and the face on the top is black.

This probability is equal to the proportion of black area in the total area of the cube.

We can define the side of the original cube as A=5a, being a the side of the small cubes.

The area that is painted black is equal to the sum of 6 squares of side A. In terms of a, that is:

$S_b=6\cdot A^2=6\cdot(5a)^2=6\cdot25a^2=150a^2$

The total area of the 125 small cubes is:

$S=125(6a^2)=750a^2$

Then, the ratio of black surface to the total surface is:

$s_b/s=(150a^2)/(750a^2)=0.2$

Then, we can conclude that the probability that a randomly selected small cube is rolled and the face on the top is black is P=0.2.

The perimeter of a triangle is 45 centimeters. find the lengths of its sides if the longest side is 7 centimeters longer than th

dangina [55]

X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7

x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19

The sides are 12, 14, and 19 cm. long. Hope this helped!
