Answer:

  38.13 = 12 +4.75h

  5.5 hours

Step-by-step explanation:

(a) The charge (c) for renting a bike for h hours is ...

  c = helmet charge + hourly charge × hours

  c = 12.00 +4.75h

To find the number of hours when the charge is 38.13, we would use the equation ...

  38.13 = 12.00 +4.75h

__

(b) To solve this 2-step linear equation, we first subtract the constant

  26.13 = 4.75h

then we divide by the coefficient of the variable.

  26.13/4.75 = h ≈ 5.5

Amanda rented the bike for 5.5 hours.

Additional comment

The result of the division is a long repeating decimal that starts off 5.50105263.... The instructions tell you to round this to the nearest tenth: 5.5. It helps to follow instructions.

The factored form of the given expression 12a - b, is not possible.

To determine the factor form of 12a-b.

In mathematics, the process of operating and interpreting a function to make it simpler or more understandable is known as simplifying, and the process is known as simplification.

here,
Given expression = 12a -b
The factored form for the given expression, cannot be determined because the given expression is a simplified expression its factor cannot be possible.

Answer:

328

Step-by-step explanation:

To find the lenght of the far left side use SOH, CAH, TOA

we have the hypotonouse and need the opposite side so we'll use SOH

sin(38)=x/26

26sin(38)=16

Then use pathagoreyous theroem to solve for the last side

a²+16²=26²

a= 20.4882

Then the area is just length*width so

16*20.4882=327.9599 which rounds to 328

Answer:

Solution given:

we have

sin 38=opposite/hypotenuse

opposite=breadth [w=b]=sin38*26=16

by using Pythagoras law

l²+b²=26²

l²=26²-16²

l=√420

l=20.5

now

Area =l*w=20.5*16=328cm²

Answer:

A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected. For example, suppose we have a set of three letters: A, B, and C. ... Each possible selection would be an example of a combination. The complete list of possible selections would be : AB, AC, and BC.

Answer:

- 9 -( -4) = -5

Step-by-step explanation:

-9-(-4)

solve the one in the bracket first because there is a minus sign between 9 and the bracket so we cannot use the 9 to multiple the number four in the bracket.

-9+4

the sign has changed to positive because when negative numbers are multiplying each other to will turn in to become positive.

so -9+4= -5

solution.

-9-(-4)

-9+4

-9+4= -5

therefore the answer is -5.

Answer:

Step-by-step explanation:

the number is 46

Answer:

a) (6,4)

b) (5, 4.5)

Step-by-step explanation:

much like when you find them midpoint where you average the x-coordinates and the y-coordinates to find the midpoint coordinates, you'll do the same thing here.

to set context, a midpoint would break the segment into a ratio of 1:1.

so in the first part, a ratio of 1:2 means you are breaking the segment into 3-parts. So you'll do this for the coordinates:

[tex]x = \frac{8 + 2}{3} \: and \: y = \frac{3 + 6}{3} [/tex]

for the second part as the ratio is 1:3, you are breaking the segment into 4 parts.

[tex]x = \frac{6 + 2}{4} \: and \: y = \frac{4 + 6}{4} [/tex]

Answer:

A 5.5% = 5400 B 5% = 1800

Step-by-step explanation:

A + B = 7200

A * 0.055 + B * 0.05 = $387

A = 7200 - B

(7200 - B)*0.055 + B*0.05 = 387

396 - 0.055B + 0.05B = 387

396 - 0.005B = 387

0.005B = 9

B = 1800

A = 7200 - B = 7200 - 1800

A = 5400
