The sketches below show cat's and Fred's driveways. If the perimeter of each others of their driveways is the same, what is the length and width of Cat's driveway?
Answers
Answer:
40,12
Step-by-step explanation:
u count how many x's u have.4(for the first square)
add up the regular numbers
so u should have4x+50
repeat for the second one
so u should have 4x+25=6x+20
solve
u get 2x=30 simplify
u get 15
now plug it in and there is ur answer
The value of length and width for Cat's driveway are 25 ft and 7.5 ft respectively.
What is a rectangle?A rectangle is a type of parallelogram having equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
Given that,
The length and width of Cat's driveway are 25 ft and x ft respectively.
And, the length and width of Fred's driveways are 2x ft and x + 10 ft respectively.
The perimeter of a rectangle is given as,
2(l + b)
Substitute the values to obtain the perimeters as,
Perimeter of Cat's driveway = 2( x + 25) ft
And, perimeter of Fred's driveway = 2(2x + x + 10) ft.
As per the question,
2( x + 25) = 2(2x + x + 10)
=> ( x + 25) = (2x + x + 10)
=> x = 15/2
= 7.5
Hence, the length and width of Cat's driveway are 25 ft and 7.5 ft respectively.

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.

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.

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.

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.

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
