Answer:

65%

Step-by-step explanation:

20 = 100%

7 = x%

7•100 ÷ 20 = 35%

so 35% is spent on rent so the other 65% that rest is the answer .

Answer:

C

Step-by-step explanation:

let the shortest piece be x then the second piece is x + 4 and the third piece is

2(x + 4) = 2x + 8

sum the 3 pieces and equate to 84

x + x + 4 + 2x + 8 = 84

4x + 12 = 84 ( subtract 12 from both sides )

4x = 72 ( divide both sides by 4 )

x = 18

that is the shortest piece is 18 cm

Answer:

C

Step-by-step explanation:

let the first piece be k cm long

so rhe length of the second piece is k+4 cm

the length of the third piece is 2(k + 4) cm

so, the first piece is the shortest and is equal to

84 = (k + k+4 + 2k+8)

84 = 4k+12

so k = 72÷4

= 18

One of the most basic ideas within the number system is that there is a 10-to-1 relationship between the values of any two adjacent places

A decimal number is a number that consists a whole and a fraction part separated by a decimal point.

When multiplying decimals, we must follow these steps:

By understanding place value, we can interpret the meaning of each digit in a decimal number

For example, if we multiply 73.24 ✕ 5.1, we will first multiply 7324 by 51. Then, counting all the decimal of the factors, there are 3 decimal places altogether. From the rightmost digit of the product to the left, count the same decimal places and put the decimal point

Hence, the number of the decimal places in the factors, when added up, is equal to the number of the decimal places in the product.

Step-by-step explanation:

what is the question ?

how much water does the full bucket contain ?

if so, then I understand that

11 2/3 gallons = 5/6 bucket

(11×3 + 2)/3 gallons = 5/6 bucket

35/3 gallons = 5/6 bucket

what do we need to do to get 1 bucket (5/5 or 6/6 or 3/3 or ...) on the right side ?

we multiply everything by 6/5 :

35/3 × 6/5 gallons = 5/6 × 6/5 bucket

(6×35)/(5×3) gallons = 1 bucket

(2×7)/(1×1) gallons = 1 bucket

14 gallons = 1 bucket

the bucket can contain 14 gallons of water.

The length and width of the rectangle are 50 metres and 10 metres respectively.

A rectangle is a quadrilateral with opposite sides parallel to each other and opposite side equal to each other.

The length of a rectangle is five times its width.

Therefore,

l = 5w

The perimeter of the rectangle is 120metres.

Hence,

perimeter of the rectangle = 2(l + w)

where

Therefore,

120 = 2(5w + w)

120 = 2(6w)

120 = 12w

divide both sides by 12

w = 120 / 12

w = 10 metres

l = 5(10)

l = 50 metres

Therefore,

width = 10 metres

length = 50 metres

Eric borrowed $3300 from the first loan and $3000 - $3300 = $-300 from the second loan (which is not possible). This means that the solution is not valid and Eric may have made a mistake in calculating the interest.

Interest is a fee charged by a lender to a borrower for the use of money. It represents the cost of borrowing money and is typically expressed as a percentage of the loan amount. Interest is paid over a period of time and is calculated based on the principal amount of the loan, the interest rate, and the length of the loan term.

There are two main types of interest: simple interest and compound interest. Simple interest is calculated only on the principal amount of the loan, while compound interest is calculated on both the principal and the accumulated interest over time. Compound interest results in a faster growth of the loan balance compared to simple interest.

Let's call the amount Eric borrowed from the first loan "A" and the amount he borrowed from the second loan "B". We can set up two equations to represent the simple interest he owed on each loan after 2 years:

A * 0.03 * 2 = interest owed on loan 1

B * 0.025 * 2 = interest owed on loan 2

The total interest owed on both loans after 2 years is $165:

A * 0.03 * 2 + B * 0.025 * 2 = 165

We also know that Eric borrowed a total of $3000:

A + B = 3000

We can substitute the second equation into the first to get an equation in terms of one variable:

A * 0.03 * 2 + (3000 - A) * 0.025 * 2 = 165

Expanding and simplifying the right side:

A * 0.03 * 2 + 3000 * 0.025 * 2 - A * 0.025 * 2 = 165

A * 0.03 * 2 - A * 0.025 * 2 = 165 - 3000 * 0.025 * 2

A * (0.03 - 0.025) = 165 - 3000 * 0.025 * 2

A * 0.005 = 165 - 3000 * 0.025 * 2

A = 165 / 0.005 + 3000 * 0.025 * 2 / 0.005

Solving for A:

A = 3300

So, Eric borrowed $3300 from the first loan and $3000 - $3300 = $-300 from the second loan (which is not possible). This means that the solution is not valid and Eric may have made a mistake in calculating the interest or the amounts borrowed.

The equation of the line that has a slope of -4 and goes through -1,6 is  4x-y+2 = 0

In general, a straight line has the equation y = mx + c, where m denotes the gradient and y = c denotes the point at which the line intersects the y-axis. The y-axis intercept is denoted by the value c. A straight line with a gradient of m and an intercept of c on the y-axis has the equation y = mx + c. Finding the slope and y-intercept will allow you to write the equation of a graphed line in y-intercept (y=mx+b) form. Slope is defined as the ratio of y-to-x changes. Choose two points on the line, and then create a sloping triangle joining them.

The equation of a straight line that passes through a point [x1 , y1} and having a slope ‘m’ is given by (y - y1) = m (x - x1)

Given m = 4 and point ( 1,6), then the equation of the line is

If each unit on the coordinate plane represents one mile, Michael does not live far enough from the school for bus service.

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

Based on the information provided about Michael, we know that he is living at the closest point to the school (the origin) on Maple Street,  which is represented by the line y = 4x + 6.

Therefore, slope (m) = 4

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

4 × m₂ = -1

m₂ = -1/4

Since line 2 passes through the origin (0, 0), it can be modeled by this equation;

y = mx + c

y = -1/4(x) + 0

y = -x/4

Now, we can determine the coordinates for the location of Michael's house;

4x + 6 = -x/4

16x + 24 = -x

16x + x = 24

17x = 24

x = 24/17

x = 1.41

y = -x/4

y = -1.41/4

y = -0.35

Therefore, the coordinates of Michael's house is (1.41, -0.35).

For the distance from Michael's house to school, we have:

Distance = √[x² + y²]

Distance = √[1.41² + (-0.35)²]

Distance = √(1.9881 + 0.1225)

Distance = 1.45 mile.

In conclusion, Michael does not live far enough from the school for bus service because a distance of 1.45 mile is less than 3 miles.

The value of DP is 35.5.

Let's denote the radius of the circumcircle of AABC as R. Since P is the circumcenter of AABC, we know that PA = PB = PC = R. From the given information, we know that PC = 35, so R = 35.

Next, let's use the Pythagorean theorem to find DP. We have two right triangles: APD and BPD. Let's start with triangle APD. We know that PA = R = 35 and AD = 7x - 6. Using the Pythagorean theorem, we have:

DP² = PA² + AD²

DP² = 35² + (7x - 6)²

DP² = 1225 + 49x² - 84x + 36

Next, let's use the Pythagorean theorem on triangle BPD. We have PB = R = 35 and DB = 5x + 8. Using the Pythagorean theorem, we have:

DP² = PB² + DB²

DP² = 35² + (5x + 8)²

DP² = 1225 + 25x² + 160x + 64

Since DP is the same in both triangles, we can equate the two expressions for DP²:

1225 + 49x² - 84x + 36 = 1225 + 25x² + 160x + 64

24x = 128

x = 128/24

x = 5/2

Substituting x = 5/2 into the expression for AD or DB, we get:

AD = 7 × 5/2 - 6 = 15/2

DB = 5 × 5/2 + 8 = 25/2

Finally, substituting x = 5/2 into the expression for DP, we get:

DP² = 35² + (7 × 5/2 - 6)²

DP² = 35² + (15/2)²

DP² = 35² + 15²/4

DP² = 1225 + 225/4

DP² = 1225 + 56.25

DP = 35.5
