On a map of Illinois, the distance between Chicago and Algonquin is 3.2 centimeters. If 2 centimeters = 40 kilometers, what is the approximate distance between the two cities?
Answers
Final answer:
The approximate distance between Chicago and Algonquin is 64 kilometers.
Explanation:
To find the approximate distance between Chicago and Algonquin, we can use the given scale of 2 centimeters = 40 kilometers. Since the distance on the map is 3.2 centimeters, we can set up a proportion to find the actual distance:
2 cm / 40 km = 3.2 cm / x km
Cross multiplying, we get 2x = 40 x 3.2, which simplifies to 2x = 128. Dividing by 2, we find that x is equal to 64. Therefore, the approximate distance between Chicago and Algonquin is 64 kilometers.

In 34 pound of a spice mix, there is 56 cup of cinnamon.
How much cinnamon does the spice mix contain per pound?
5/8 cup
9/10 cup
1 1/9 cups
1 3/5 cups
Answers
56 cups cinnamon
------------------------- = 1.64 cups of cinnamon per pound.
34 pounts
This result (11/17 cups/lb) does not match any of your 4 answer choices, but is closest to 1 3/5 cups/lb.
To determine the amount of cinnamon per pound of the spice mix, divide the total cups of cinnamon (56) by the total pounds of the mix (34), resulting in approximately 1.647 cups per pound. This equates to 1 3/5 cups of cinnamon per pound, which is the closest option.
Explanation:The question asks us to calculate how much cinnamon is contained in each pound of a spice mixture if we know that there are 56 cups of cinnamon in 34 pounds of the spice mix. To find the cinnamon content per pound, we'll divide the total number of cups of cinnamon by the total number of pounds of the spice mix.
Here is the calculation:
56 cups cinnamon / 34 pounds spice mix = cups per pound.
Doing the division, we get: 56 / 34 = 1.647 cups, which we need to express as one of the provided options. The nearest option to 1.647 is 1 3/5 cups, or 1.6 cups, when rounded to the nearest fraction.
Therefore, the spice mix contains 1 3/5 cups of cinnamon per pound.

What are two partial products you could add to find 990x37
Answers
To find the product of 990 and 37 using partial products, break down each number into its place value components and multiply accordingly.
Explanation:To find the product of 990 and 37 using partial products, we can break down each number into its place value components. First, we multiply the ones place of 990 by the ones place of 37, which gives us 0. Next, we multiply the tens place of 990 by the ones place of 37, which gives us 370. Finally, we multiply the hundreds place of 990 by the ones place of 37, which gives us 3330. Adding all these partial products together, we get 3700 + 3330 + 0 = 7030.
Help me please To solve the task Mrs. Hilt had $4,000 in her savings account. She earned 10% interest each year. If she left that money in the account for one year, how much will she have in the account at the end of that year?
Answers
Mrs. Hilt will have $4,400 in her savings account at the end of one year after earning 10% interest on her initial $4,000 deposit.
To solve the task of determining how much Mrs. Hilt will have in her savings account after one year, we need to calculate the interest earned and add it to the original amount. Mrs. Hilt has $4,000 in her account, and the annual interest rate is 10%.
The interest Mrs. Hilt will earn in one year is calculated by multiplying the principal amount by the interest rate: $4,000 x 0.10 = $400. Therefore, the total amount in the account after one year, which includes the original principal and the interest earned, is $4,000 + $400 = $4,400.
In summary, Mrs. Hilt will have $4,400 in her savings account at the end of one year, based on a 10% annual interest rate.

Answers

2) [B]: "70.9%" .
_________________
3) "66[tex] \frac{2}{3} [/tex]%" ; or, "66.6666... % " ; or, round to: "66.667 %" ;
or; round to: "66.67%" .
_____________________________________
Explanation:
_____________________________________
1) "Rename one-eight as a percent".
→ [tex] \frac{1}{8}[/tex] = 1 ÷ 8 = 0.125 ;
→ [tex] \frac{x}{100}[/tex] = 0.125 ;
→ x = 0.125 * 100 = {move the decimal point in the number, "0.125"; two spaces forward, since we are MULTIPLYING, by "100" (which has 2 zeros);
→ x = 12 * 100 = 12.5 .
So: → [tex] \frac{12.5}{100}[/tex] = 12.5 % ; since "12.5 % = 12.5/100 "
_____________________________________
Other method:
_____________________________________
→ [tex] \frac{x}{100}[/tex] = [tex] \frac{1}{8}[/tex] ;
→ x = 100 * [tex] \frac{1}{8}[/tex] ;
→ x = [tex] \frac{100}{1}[/tex] * [tex] \frac{1}{8}[/tex] ;
= [tex] \frac{100*1}{1*8} [/tex] ;
= [tex] \frac{100}{8} [/tex] ;
→ x = 12.5 ;
→ [tex] \frac{x}{100} [/tex] = [tex] \frac{12.5}{100} [/tex] = 12.5% ;
→ 12.5 % = [tex] \frac{12.5}{100} [/tex] ;
= ?
→ {Take the "12.5" & move the decimal backward TWO (2) places, since we are "dividing" by "100" (which has 2 "zeros") ;
= 0.125 = [tex] \frac{125}{100}[/tex] = [tex] \frac{1}{8} [/tex].
_________________________________________________
2) "Rename "0.709" as a percent."
===> [tex] \frac{x}{100} [/tex] = 0.709 ;
→ x = 0.709 * 100 = ? ;
Note: Take the "0.709" ; & move the decimal place "2 (TWO)" spaces forward, since are MULTIPLYING by "100" (which has 2 zeros); to get:
→ x = 70.9 ;
→ x = 0.709 * 100 = 70.9 ;
→ [tex] \frac{x}{100} [/tex] = [tex] \frac{70.9}{100} [/tex] = 70.9% ;
→ which is: Answer choice: [B] .
→ 70.9% = [tex] \frac{70.9}{100} [/tex] = ? ;
{take the "70.9" ; and move the decimal point backwards TWO (2) decimal places; since we are DIVIDING by "100" (which has "2 (two) zeros") ;
→ 70.9% = [tex] \frac{70.9}{100} [/tex] = 0.709 .
__________________________________________________
3) What percent is equivalent to two-thirds?
__________________________________________________
→ [tex] \frac{x}{100} [/tex] = [tex] \frac{2}{3} [/tex] ;
x = [tex] \frac{2}{3} [/tex]*100 ;
= [tex] \frac{2}{3} [/tex]*[tex] \frac{100}{1} [/tex] ;
= [tex] \frac{2*100}{3*1} [/tex] ;
= [tex] \frac{200}{3} [/tex] ;
= 66[tex] \frac{2}{3} [/tex] ;
→ { 66[tex] \frac{2}{3} [/tex] } / 100 = 66 [tex] \frac{2}{3} [/tex] % ;
or, write as: 66.666666....% ; or, round to:
66.67%
{since: " [tex] \frac{2}{3} [/tex] " = 2 ÷ 3 = 0.66666..." .

One-eighth, when converted to a percent, is 12.5%. The decimal 0.709 is equivalent to 70.9% when converted to a percent. Two-thirds is roughly equivalent to 66.7% after conversion and rounding.
Converting Fractions and Decimals to Percents
To convert a fraction to a percent, you can either first convert it to a decimal or multiply the fraction straightaway by 100. For one-eighth, we multiply 1/8 by 100 to get 12.5%. So one-eighth as a percent is 12.5%.
To rename 0.709 as a percent, you move the decimal point two places to the right or multiply by 100, which gives us 70.9%. Therefore, 0.709 as a percent is 70.9%.
Lastly, two-thirds is equivalent to the decimal 0.666... (repeating). To turn this into a percent, we again multiply by 100, yielding approximately 66.7%, after rounding.

Answers
please vote my answer brainliest. thanks!
To find out how much more Christians turkey weighs than Graces, convert the weights to the same unit and subtract Graces turkey weight from Christians turkey weight. The difference is 11.125 pounds.
Explanation:To find out how much more Christians turkey weighs than Graces, first convert the weights of the turkeys to the same unit. Then subtract Graces' turkey's weight from Christians' turkey's weight.
To convert 6 pounds and 14 ounces to pounds, divide the 14 ounces by 16 and add the result to 6. This equals 6.875 pounds.
Now subtract Graces' turkey weight from Christians' turkey weight: 18 pounds and 3 ounces - 6.875 pounds = 11.125 pounds. Therefore, Christians' turkey weighs 11.125 pounds more than Graces' turkey.
suppose you earn $7.25 per hour working part-time for a florist. Write and solve an inequality to find how many full hours you must work to earn at least $125
Answers
with that out of the way, the keyword "at least" makes it so that you can get 125 or more in t hours.
The inequality is $125<=7.25t.
Now you can use the guess and check method, for this example we'll use t=18 and t=17.
7.25(18)=$130.5
7.25(17)=$123.25
Therefore, the answer is 18, because 18 gives you a number greater than or equal to $125

A book has a front and a back and 400 pages. The front and back cover are each 0.9mm thick measured to 1 decimal place. Each page is 0.13 mm thick measured to 2 decimal places. Calculate the minimum thickness of the book.
Answers
Answer:
Step-by-step explanation:
0.9 UB=0.95
0.9 LB=0.85
0.13 UB= 0.135
0.13 LB= 0.125
0.85x2=1.7
0.125x400=50
1.7+50=51.7
Minimum thickness=51.7mm
To calculate the minimum thickness of the book, add up the thickness of the front cover, the back cover, and all the pages. The minimum thickness of the book is 54.8mm.
Explanation:To calculate the minimum thickness of the book, we need to add up the thickness of the front cover, the back cover, and all the pages. The front cover has a thickness of 0.9mm, the back cover has a thickness of 0.9mm, and each page has a thickness of 0.13mm. There are 400 pages in the book. So, the minimum thickness of the book can be calculated as:
Front cover thickness + Back cover thickness + (Number of pages x Page thickness)
0.9mm + 0.9mm + (400 x 0.13mm) = 0.9mm + 0.9mm + 52.0mm = 54.8mm

charles leaves the marina and sails his boat 10° west of north for 1.5h at 18km/h. he then makes a right turn to a heading of 60° east of north and sails for 1 2h at 20km/h a) at the end of time how far is charles from his starting point to his nearest km
Answers
The total distance from Charles' starting point at the marina to his destination is calculated by adding the vectors representing each leg of his journey and using the Pythagorean theorem to find the length of the resultant vector. This comes out to be approximately 40 km.
Explanation:This problem can be solved using vector addition and the Pythagorean theorem. Charles’ first leg of the journey is 10° west of north, therefore we could consider it as a vector directed north-west. Charles travels 1.5h at 18 km/h, therefore the lenght of this vector is 27km. Charles’ second leg of the voyage heads 60° east of north, that could be considered as a vector heading north-east. He sails for 1.5h at 20 km/h resulting in a vector of 30 km.
Now, if we place these two vector head to tail keeping their direction intact, we form a right triangle. Using Pythagorean theorem, the hypotenuse of the triangle will give us the distance from initial to final point. Therefore, the formula becomes √(27² + 30²) = √(729 + 900) = √1629 ≈ 40.36 km which is approximately 40 km to the nearest kilometer.
