Answer:

15. 24.5 m

16. 11 cm

17. 29.75 m

18. 1.4 cm

Step-by-step explanation:

15. each 1 cm in the drawing is equal to 3.5 m in real life so a distance of 7 cm in the drawing would be 7×3.5 because in the drawing, you are traveling 7 times the distance of 1 cm so in real like you would travel 7 times the distance of 3.5 m

16. the distance in real life is 38.5 m so to find the distance in the drawing, you would need to divide the real life distance by 3.5 so 38.5÷3.5=11 cm

17. to calculate real life measurement, you would need to add up all the distances David's aunt traveled in the drawing

1 cm + 4.5 cm + 2 cm + 1 cm = 8.5 cm

next, to calculate real distance, you would multiply 8.5 and 3.5 so 8.5×3.5=29.75 m

18. To find distance on cindys map, we will need to first find real life distance on original map and then convert the real life distance into cm on the scale that cindy has on their map.

On the original map where 1 cm = 3.5 m, davids house to the library is 2 cm so to find real life distance from this map would multiply 3.5 by 2 so 3.5×2=7 m

Next, we need to convert this to the scale on Cindy's map, where 1 cm = 5 m so now we need to divide 7 by 5 to get to cm so 7÷5 = 1.4 cm on cindys map

In front-end estimation, we replace the original number with a number that's close by but only has one non-zero digit. For example, 20, 300, -50, 1,000, 80,000. Take the number 32; the choices to replace it with are 30 or 40 (they both have only one non-zero digit)

Step-by-step explanation:

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

9a+5(3-a)=11  given

Distribute the 5 using the distributive property

9a +15 -5a = 11

Combine like terms, using simplification

4a +15 =11

Subtract 15 from each side, using the subtraction property of equality

4a+15-15 = 11-15

4a = -4

Divide each side by 4 using the division property of equality

4a/4 = -4/4

a = -1  by simplifying

C) $40.50

Step-by-step explanation:

It is given to you that 20 articles cost $90. Find the unit cost of the articles. Divide the total cost of the articles with the amount of articles there are:

$90/(20 articles) = $4.50/article.

Each article costs $4.50 each.

Next, find the cost of 9 articles. Multiply the total amount of articles with the unit cost:

4.50 x 9 = 40.50

C) $40.50 is your answer.

The required distance around the hat is approximately 21.35 inches.  Option C is correct.

To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and d is the diameter of the circle.

Here,
The distance around a circle is given by the formula circumference = π × diameter.

Substituting the given values, we get:

circumference = 3.14 × 6.8

circumference = 21.352

Rounding to the nearest hundredth, we get:

circumference ≈ 21.35 inches

Therefore, the distance around the hat is approximately 21.35 inches.

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².

9 the rolls will result in a sum greater than 10 if the experiment is repeated 108 times.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.

As, Expected number of outcomes = theoretical probability * number of trials

Expected number of outcomes = 3/36 x 108

                                                    = 9

Thus, the required value is 9.

Answer:

270 pounds

Step-by-step explanation:

half of 12 is 6, so 18. Then you take half of 180 and add to 180

Answer:

18 hours = £270

Step-by-step explanation:

Find how much he charges per hour. Divide:

\(\frac{180}{12}=15\)

So ha charges about 15 an hour. Multiply this price by the number of hours:

\(15*18=270\)

Therefore, he will charge £270 for a job that takes 18 hours.

OR

Set a proportional relationship since he charges a fixed amount:

\(\frac{price}{time}=\frac{price}{time}\)

Insert the appropriate corresponding values:

\(\frac{180}{12} =\frac{x}{18}\)

Solve for the price after 18 hours of work, represented by x. Cross multiply:

\(12(x)=180(18)\\\\12x=3240\)

Solve for x. Use inverse operations to isolate the variable. Divide both sides by 12:

\(\frac{12x}{12} =\frac{3240}{12} \\\\x=270\)

Therefore, after 18 hours, he will charge £270.

Step-by-step explanation:

ist you have to lind the lcd of each fraction. that would be 10.

1/2x5/5=5/10 of the boys have brown eyes

1/5x2/2=2/10 of the boys have blue eyes

3/10=3/10 of the boys have hazel eyes

The question is asking to see how many more boys have brown eyes than hazel eyes.

Subtract 3/10 from 5/10

and that gives you 2/10

The answer is 1/5.

We know that half of the boys in Jason's class has brown eyes, while three-tenths of the boys in his class have hazel eyes. Therefore, if we subtract the two values, you should get your answer.

\(\frac{1}{2} -\frac{3}{10} =\frac{2}{10}\)

1/5 is the simplified version of 2/10. Therefore, 1/5 is your answer.

Answer:

1. 420°C – 98°C = 330°C

2. 480°C – ⁻230°C = 480°C + ⁺230°C = 710°C

3. 659°C – 1083°C = ⁻424°C

4. 212°F – ⁻44°F = 212°F + ⁺44°F = 256°F

5. 32°F – ⁻150°F = 32°F + ⁺150°F = 182°F

6. 400°C – ⁻180°C = 400°C + ⁺180°C = 580°C

7. Oxygen freezes first since ⁻218.79 °C > ⁻252.8 °C

⁻218.79 °C - –252.8 °C = ⁻218.79 °C + ⁺252.8 °C = 34.01 °C

8. 1°C – ⁻9°C = 1°C + +9°C = 10°C

9. 260°F – ⁻280°F = 260°F + ⁺280°F = 540°F

10. 1762°F – 1946°F = ⁻184°F

Answer:

88/27

Step-by-step explanation:

Convert (2+(2/3)) into a improper fraction. To do this multiply the denominator (3) by the whole number (2) and add the numerator (2). (3*2)+2 = 8. Then put 8 over a denominator which is equal to the denominator of the mixed fraction. So (2+ (2/3) is 8/3) Do the same process with the other fraction.

Then multiply the numerators and denominators of the improper fractions:

(8/3)*(11/9) gives (88/27).

Answer:

108

Step-by-step explanation:

So we can break this figure into 2 shapes. A rectangle and a right triangle.

Once we do that, we can solve the area for each shape.

Rectangle: 6 x 3 = 18

For the triangle, we'll need to find the sum of 6 + 6, which would be 12 to find the missing height for the triangle. Then we can find the area.

Triangle: (12 x 15)/2 = 90

We can then add our two answers up to get our final answer.

                                            18 + 90 = 108
