Answer:

70 kilometers

Step-by-step explanation:

Set up a proportion where x is the actual distance

[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]

Cross multiply:

x = (20)(3.5)

x = 70

So, the actual distance is 70 km

Answer:

d = 0.4

Step-by-step explanation:

-10 (d + 1) = - 14

=> -10d - 10 = -14

=> -10d = -14 + 10

=> -10d = -4

=> 10d = 4

=> d = 4 / 10

=> d = 0.4

Answer:

x=-11, -1, and 3

Step-by-step explanation:

x^3+9x^2-25x-33=0

There are formulas to solve cubics, but that probably is not the way you are expected to go.  Here is a trial and error approach that works in this case.

Assume that the cubic can be factored and that the roots are r1, r2, and r3.  Then the factored form is

(x-r1)(x-r2)(x-r3)=0

This shows that the constant must equal the product of the roots.

(r1)(r2)(r3)=-33

One possibility is that the roots are integers.  In this case, a factor of 33 might work.  Prime factorization of 33 gives 3 and 11.  Try 3.  Then (x-3) is a factor.

Divide the cubic by (x-3).  It works. the result is

x^2+12x+11

This has factors of (x+11) and (x+1).  Therefore, the roots are 3, -1, and -11

Answer:

697109 pennies

Step-by-step explanation:

First, you use the formula A = P (1 + rt).

R= rate which is 5.3%

T= time which is 7 years.

P is the principle which is 18790

A= is the answer

so first you multiply 7*5.3% which you get 0.371

then you multiply that with 18790 which then you get 6971.09

if you want pennies you multiply it with 100 to get 697109

========================================================

In 1985, there were 20 students

In 2005, there were 45 students

This is a change of 45-20 = 25 students.

This amount of change is divided by the original amount 20 to get 25/20 = 1.25 and converts to 125% when you move the decimal point 2 spots to the right.

-------------

If you want, you can use the formula below

x = old value = 20

y = new value = 45

z = percent change

z = [ (y-x)/x ] * 100%

z = [ (45-20)/20 ] * 100%

z = (25/20) * 100%

z = 1.25*100%

z = 125%

The z value being positive means we have a percent increase.

It's possible to have over 100% increase since 100% of 20 is 20. Having a 100% increase means we increased by 20. Since we increased by more than 20, this means the increase must be over 100%.

Answer:

these are the equivalwnt expressions 4/5×15=4×5/15; 5×3=3×15/5

The expression equivalent to 4/5 × 15 is 4×3

According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.

Given here the expression 4/5×15 thus simplifying it we get

4/5×15= 4×3

           = 12

Hence, The expression equivalent to 4/5 × 15 is 4×3

He made $1 944 in commission

Answer:

$76.32

Step-by-step explanation:

First, add up all the costs for everything:

17 + 30 + 25 = 72

Now, we need to add the sales tax. To do this we multiply 72 by 1.06. This is because the sales tax is 6% (the decimal form of 6% is 0.06), and we add it on to the 100% cost (which is 1 in decimal form).

(72)(1.06) = 76.32

Therefore the total cost of everything Walter bought plus the tax rate is $76.32.

Answer:

I got 104

Step-by-step explanation:

From our given information, since Angle DGF from a 90 degree angle, Due to our linear pair rule EGF is also a perpendicular angle. EGF and DGC are vertical angles so Angle DGC is 90 degrees.

Triangle DGC have two interior angles 90 and 37 so using the triangle interior theorem we can find the 3r

d side

[tex]90 + 37 + x = 180[/tex]

[tex]127 + x = 180[/tex]

[tex]x = 53[/tex]

Know that angle is 53 we can add 53 and 51 together to find Angle D full degree measure is 104.

Adjacent angles in parallelogram are supplementary so angle d plus angle c equals 180.

Angle C measure has to add up to 76 then so

[tex]37 + x = 76[/tex]

[tex]x = 39[/tex]

So the missing angle is 39 and angle c full side measure is 76.

Angle B and Angle C

are also adjacent angles so

[tex]76 + x = 180[/tex]

x=104

B=104

Answer:

286.5 in.²

Step-by-step explanation:

The surface area of the prism = sum of the area of each surface

= (7.5*3) + (11.5*3) + (7.5*3) + (11.5*3) + (11.5*7.5) + (11.5*7.5)

= 22.5 + 34.5 + 22.5 + 34.5 + 86.25 + 86.25

Surface area = 286.5 in.²

Answer:

Answer:

B

Step-by-step explanation:

Assuming Part A is the situation where the bags aren't merged, the probability of drawing a "1" followed by a "B" is (1/3)(1/4) or 1/12. This is because you have a 1/3 chance of getting a "1" and a 1/4 chance of getting a "B".

Now if we merge the bags, we have a 1/7 chance of getting a "1". We then have a 1/6 chance of getting a "B". This is because after we complete the first draw, the bag only has 6 remaining not 7. This gives us a probability of (1/7)(1/6) or 1/42.

So we know the probability will change so C is wrong. In both scenarios, we draw two balls anyways so A is wrong.

This leaves B, which is supported by the reasoning presented above.
