Answer:

  C.  define all variables

Step-by-step explanation:

Equations for word problems will depend on the problem. Not all of the equations will be linear equations. Even if they are, they are not necessarily easily written in any particular form, or easily solved when they are written in that form. The nature of the equations will depend on the problem.

One thing that must be done in any case is define all variables. It is usually a good idea to define the units of the variable(s) as well. Sometimes problems are posed with numbers in incompatible dimensions, or they may ask for an answer in dimensions different from those used in the given information. In order to avoid confusion and to be sure you have the desired answer, you need to make sure the variables and their dimensions are compatible with the solution process.

Answer:

B. 75%

Step-by-step explanation:

multiply the numerator and the denominator by 25. 3*25/4*25=75/100. 3/4=75%.

Answer:

75%

Step-by-step explanation:

Start by converting the fraction 3/4 into decimal

Divide the numerator by the denominator: 3 ÷ 4 = 0.75

Multiply the decimal by 100 and write the result with the percentage sign at the end 0.75 × 100 = 75%.

your awnser is, 3/4 = 75%

The probability of drawing a white ball from box B is 7/8 or approximately 0.875 (87.5%).

Let's calculate the probability of drawing a white ball from box B after transferring 3 balls from box A to box B.

Given:

Box A contains 5 white balls and 4 black balls.

Box B contains 3 white balls and 5 black balls.

After transferring 3 balls from box A to box B, we need to consider two scenarios:

The ball drawn from box B comes from the 3 transferred balls.

The ball drawn from box B comes from the original balls in box B.

Let's calculate the probability for each scenario and then sum them to obtain the total probability.

After transferring 3 balls from box A to box B, box B will contain 6 balls (3 white and 3 black), while box A will contain 2 white balls and 4 black balls.

The probability of drawing a white ball in this scenario is 3/6, as there are 3 white balls out of a total of 6 balls in box B after the transfer.

In this scenario, we consider that the ball drawn from box B comes from the original balls in box B, meaning it was not transferred from box A.

The probability of drawing a white ball in this scenario is 3/8, as there are 3 white balls out of a total of 8 balls in box B before the transfer.

Now let's sum the probabilities of both scenarios to obtain the total probability:

Total Probability = (Probability of Scenario 1) + (Probability of Scenario 2)

= (3/6) + (3/8)

= 1/2 + 3/8

= 4/8 + 3/8

= 7/8

Answer:

No triangle possible

Step-by-step explanation:

The one side is to short to make a triangle

Answer: 24km^2

Step-by-step explanation: The area of the middle rectangle of the trapezoid is 3×4=12. The two triangles on the sides are both 3-4-5 right triangles and have a combined area of 12 units^2. 12+12=24!

Answer:

The surface area of the green prism is 6.25 times greater than the surface area of the blue prism.

Step-by-step explanation:

The surface area of both prisms consists of six rectangles: top, base, front, back, left side and right side. In terms of surface area, top=base, front=back and left side=right side, so the total surface area for each prism is:

2(base area)+2(back area)+2(side area)

=2((base area)+(back area)+(side area))

Area of blue prism = 2((base area)+(back area)+(side area))

=2((4*2)+(4*10)+(2*10))

=2(8+40+20)

=2(68)

=136 cm²

Area of green prism = 2((base area)+(back area)+(side area))

=2((10*5)+(25*10)+(25*5))

=2(50+250+125)

=2(425)

=850 cm²

850cm² is 6.25 times greater than 136cm² (850/136=6.25), so therefore, the surface area of the green prism is 6.25 times greater than the surface area of the blue prism.

Answer: First 12/8, then 3/2

Step-by-step explanation: 3/2.

If you want the mixed fraction, it would be 1 1/2.

4 times 3 is 12... 12/8

1 whole box (8/8)

So 12/8-8/8=4/8 left

1 whole and 1/2

Answer:

17 units is the answer

Step-by-step explanation:

Points are (1,9) and (9,-6)

Pythagorean theorem can be written as,

[tex]d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(9-1)^2 + (-6-9)^2}\\\\d=\sqrt{(8)^2+(15)^2} \\\\d=\sqrt{64+225} \\\\d=\sqrt{289} \\\\d=17[/tex]

∴ d = 17 units is the distance between 2 points.

Answer:

50 gluten-free cupcakes and 100 regular cupcakes.

Step-by-step explanation:

Let's define the variables:

R = number of regular cupcakes sold

G = number of gluten-free cupcakes sold

The total amount of money raised then is:

M = R*$2.00 + G*$3.00

We also know that:

The number of regular cupcakes sold was 2 times the number of gluten-free cupcakes sold.

then:

R = 2*G

And we also know that the amount of money raised is $350

Then we have the equations:

R = 2*G

R*$2.00 + G*$3.00 = $350

We can replace the first equation into the second one, so we have only one variable:

(2*G)*$2.00 + G*$3.00 = $350

Now we can solve this for G.

G*$4.00 + G*$3.00 = $350

G*$7.00 = $350

G = $350/$7.00 = 50

G = 50

50 gluten-free cupcakes where sold.

And using the equation:

R = 2*G = 2*50 = 100

We can conclude that 100 regular cupcakes were sold.

feet, but now 1 inch represents

✔ 24

feet.

Step-by-step explanation:

If you have a rectangle or square, each of the angles measures 90°. If you have a parallelogram or rhombus, the opposite angles are the same and the consecutive angles are supplementary. For other types of quadrilaterals you may need to add the given angles and then subtract from 360°.

[Also Pic with proof]

The change in the scale factor is

1/3.

The change of scale means that 1 inch represented 8 feet, but now 1 inch represents 24 feet.

If you have a rectangle or rectangular, each of the angles measures 90°. if you have a parallelogram or rhombus, the opposite angles are the same and the consecutive angles are supplementary. For different types of quadrilaterals, you can want to feature the given angles and then subtract from 360°.

The scale factor is a degree for similar figures, who appear the same but have distinctive scales or measures. Assume, the circle looks similar however they might have various radii. The scale factor states the scale by the way which a determined is larger or smaller than the original figure.
