Answer:

  A higher credit score

Step-by-step explanation:

Interest rates are generally set based on at least a couple of factors:

Folks who have a lower level of disposable income, or who have a history of missed payments or loan defaults are likely to have a lower credit score. Loans offered will likely have a higher interest rate than for someone with a better credit score.

Loan fees may be reduced also when interest rates are reduced.

Based on the above discussion, we see that lower loan fees, higher credit score, and lower interest rates are all positively correlated. One does not necessarily indicate another.

Of the choices offered, we suppose "a higher credit score" is most likely the desired answer.

Answer:

A higher credit score

Step-by-step explanation:

Remember, you can only get low interest rate if you have a high credit score.

Answer:

Step-by-step explanation:

He traveled at 60 mph a distance of 60*hours.

He traveled at 40 mph the same distance of 40(15 hrs - time hrs). The distance is the same; therefore, set them equal.

60t = 40(15-t)

60t = 600 - 40t

100t = 600

t = 6 hrs for the 60 mph day.

15-t = 9 hours for the 40 mph day.

distance = 6 h x 60 mph = 360 miles.

distance = 9 h x 40 mph = 360 miles.

Answer:

6.25$an hour

Step-by-step explanation:

25$=4hrs

? 1hr

Answer:

6.25$

Step-by-step explanation:

So lets think about this.

We need to find dollars per hour.

We have 25 for 4 hours.

What do we do?

Lets divide 25 by 4.

25/4

=

6.25 dollars

lets think of it this way. Dollars for 4 hours, divided by 4, equals dollars for 1 hour.

AnswerL

6.25

Hope this helps! :)

Given:

The diameter of a cylindrical aquaculture tank = 10 ft

Height = 4 ft

To find:

The volume of the tank.

Solution:

We have,

Height = 4 ft

Diameter = 10 ft

Radius is half of the diameter.

Radius = 5 ft

Volume of a cylinder is:

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting [tex]r=5, h=4[/tex] in the above formula, we get

[tex]V=\pi (5)^2(4)[/tex]

[tex]V=\pi (25)(4)[/tex]

[tex]V=100\pi [/tex]

Therefore, the volume of the tank is [tex]100\pi [/tex] cubic ft. Its approximate value is 314.16 cubic feet.

Answer:

3/20

Step-by-step explanation:

probability = Number of favourable outcomes÷Total number of outcomes

total outcomes =20 juice cans

Number of favourable outcomes =3cans of grape juice

Therefore P(E)=3÷20

Probability=3/20

=3/20

Answer:

C. 240 cu feet.

Step-by-step explanation:

The formula for the volume of a prism is V = Bh. ("B" is the base area and "h" is the height.) When you substitute the values, you get V = (24)(10). And (24)(10) = 240. Hope this helps!

Answer:

C. 32.75Is the answer!!

Step-by-step explanation:

Answer:c- sixty nine hundredths

Step-by-step explanation:

three tenths can be expressed in decimal as 3/10

thirty nine hundredths can be expressed in decimal as 39/100

Therefore the sum of three tenths plus thirty nine hundredths equals

3/10 +39/100

We first find the l.c.m of the two fractions equals 100 so we have 100 as the denominator

then 100 divided by 10  multiplied by 3 +100 divided by 100 multiplied by 39 as illustrated below gives the answer

3/10 +39/100

=30+39/100

=69/100= sixty nine hundredths

Total sum of degrees of a Triangle is 180 deg

Than: 8x-7 + x +7 + 2x + 15 = 180

11x + 15 = 180

x = (180-15) / 11  =15

Answer:

"so i need to find e missing side of each right triangle, side c is the hypotenuse!! a = 8.8ft, b= 9ft i have to round the answers to the nearest tenth if necessary "

Step-by-step explanation:

Sure! So remember that the Pythagorean theorem is a squared plus b squared = c squared.

= 8.8 squared + 9 squared = c squared

= 77.44 + 81 = c squared

[tex]\sqrt{158.44}[/tex] = c squared

c squared = (rounded) 12.6 ft

x=6,y=14

Step-by-step explanation:

make -5x+5x=40 as equation (1)

4x+3y=24...... (2)

Find equation (3) from (1)

-5x+5y=40

-5x/-5=(40-5y)-5

x= y-8............. (3)

Substitute (3) from (2)

4x+3y=24

4 (y-8)+3y=24

4y-32=24

4y=24+32

4y=56

y=14

find x from equation (3)

x=y-8

x=14-8

x=6

Answer:

small triangle area = 1/2(8)(14) = 56 m²

bigger triangle area = 1/2(16)(14) = 112 m²

biggest triangle area = 1/2(24)(14) = 168 m²

there's 2 bigger triangles so you pick the bigger one you want

Answer:

smaller triangle area = 56m²

larger triangle area = 112m²

total area = 168m²

Step-by-step explanation:

Area of triangle = [tex]\frac{bh}{2}[/tex]

where b = base length and h = height

smaller triangle dimensions

base length= 8m

height = 14m

* plug in the values into the formula *

[tex]area=\frac{8*14}{2} \\8*14 =112\\\frac{112}{2}=56\\A=56m^2[/tex]

so we can conclude that the area of the smaller triangle is 56 square meters

larger triangle dimensions

base length = 16m

height = 14m

* plug in the values into the formula *

[tex]area=\frac{16*14}{2} \\16*14=224\\\frac{224}{2} =112\\A=112m^2[/tex]

so we can conclude that the area of the larger triangle is 112 square meters

total area = the sum of the two triangle's area

total area = 112 + 56

112 + 56 = 168

hence the total area is 168 square meters
