Answer: $1,312.5 difference

Step-by-step explanation:

1050 x 1.5 = 1575

1575 x 1.5 = 2,362.5

2,362.5 - 1050 = 1,312.5

angle in triangle= 180

4 + 7+7= 18

180/18 = 10

10 = 1 part

smallest = 4 parts

10x4= 40

so answer is 40

Answer:

  (a)  40°

Step-by-step explanation:

You want the measure of the smallest angle in a triangle whose angle measures have the ratios 4 : 7 : 7.

We notice that the sum of the numbers in the ratios is 4+7+7 = 18, so multiplying by 10 will make the sum equal to 180, the number of degrees in a triangle.

  4 : 7 : 7 = 40 : 70 : 70

The smallest angle is 40°.

Additional comment

The other two angle measures are 70°.

The pack with 55 paper plates that costs $4.40 is a better buy that the pack with 85 paper plates which costs $8.08.

We must utilize the unitary method in this elementary algebra issue, which is nothing more than figuring out the price per plate in both of the cases. The cost per plate for the $8.08 box of 85 paper plates must now be determined. As a result, since 85 plates cost $8.08, 1 plate must cost $8.08/85, or around 9.5 cents per plate. When we repeat the job for the second scenario, we see that 55 plates cost $4.40, making 1 plate cost $4.40/55, or 8 cents per plate. Now that each plate costs less in the second scenario, it turns out to be a superior purchase.

Pallavi should generate her hypothesis before conducting her study.

A hypothesis is a statement that predicts the relationship between two or more variables. It serves as a guide for the research and allows Pallavi to focus her study on a specific question or problem. In this case, her hypothesis should state her prediction about the relationship between wearing a seat belt and the extent of injuries in automotive accidents.

For example, her hypothesis could be "Wearing a seat belt will significantly reduce the extent of injuries in automotive accidents." This hypothesis can then be tested and supported or disproved through her research. It's important for Pallavi to generate a clear and testable hypothesis so that she can conduct a valid study with accurate results.

Answer:

  5w +3

Step-by-step explanation:

You want the difference between (8w+5) and (3w+2).

The difference is found by subtracting 3w+2 from 8w+5:

  (8w+5) -(3w+2)

  = 8w + 5 - 3w - 2

  = (8 -3)w +(5 -2)

  = 5w +3

The difference is 5w+3.

= -6k -87=14 (k+6)

= -6k-87= 14(K+6)

= -6K-87=14K+84

Add 87 to both the sides

= -6K-87=14K+84

= -6k-87+87 =14k+84+87

Add the numbers

-6 k=14k+171

Subtract 14k from both sides

-6 k=14k+171

-6k-14k=14k+171-14k

∴-20k=171

Hanna works at an aquarium and needs to drain the seahorse tank for cleaning.

The gallons of water in the tank based on the number of minutes it has be draining is shown in the table.

Therefore, let's represent it in slope intercept form.

y = mx + b

where

Hence, using (0, 60) and (4, 50)

m = 50 - 60 / 4 - 0 = - 10 / 4 = -2.5

Therefore,

y = -2.5x + b

y = -2.5x + 60

Therefore,  y = 2.5x + 60 is not the true equation.

The equation of the line that passes through the point (3,-7) and has a slope of -4/3 is 4x + 3y + 9 = 0.

In the given question, we have to find the equation of the line that passes through the point (3,-7) and has a slope of -4/3.

A point on the line and the slope of the line are required in the point-slope version of the equation of a line. (X(1), Y(1)) serves as the line's reference point, and its slope is m. Consequently, the line equation is as follows.

(y - y(1)) = m(x - x(1))

From the given question, the value of m = -4/3 and x(1) = 3, y(1) = -7

Now putting the value in the formula

(y - (-7)) = -4/3(x - 3)

(y + 7) = -4/3(x - 3)

Multiply by 3 on both side, we get

3(y + 7) = -4(x - 3)

Now simplifying using the distributive property

3y + 21 = -4x + 12

Subtract 21 on both side, we get

3y = -4x - 9

Add 4x + 9 on both side, we get

4x + 3y + 9 = 0

Hence, the equation of the line that passes through the point (3,-7) and has a slope of -4/3 is 4x + 3y + 9 = 0.

On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

Now, According to the question:

How do you find the B intercept form?

y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line.

y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept. x and y represent the distance of the line from the x-axis and y-axis, respectively. The value of b is equal to y when x = 0, and m shows how steep the line is.

The bond would be worth amount of $1,000 when it matured after 20 years, since it pays a 6% annual yield, which means it will double in value over the 20-year period.

500 x (1 + 0.06) ^ 20 = 1000

500 x 3.51 = 1,755

1,755 - 500 = 1,255

1,255 / 2 = 627.5

627.5 + 500 = 1,127.5

1,127.5 x 2 = 2,255

2,255 - 1,755 = 500

500 x 2 = 1,000

The bond is worth $500 when Kent buys it at 22 years old, and will pay a 6% annual yield. This means that the value of the bond will double over the 20-year period. To calculate the value of the bond at maturity, we need to use the formula: 500 x (1 + 0.06) ^ 20 = 1000. This means that the bond will be worth $1,000 when it matures 20 years later. We can also arrive at this result by breaking down the calculation into smaller steps. First, we multiply the initial bond value by the interest rate (500 x 1.06) to get the value after one year. Then, we repeat this step for the remaining 19 years (500 x 3.51) to get the total value after 20 years (1,755). We then subtract the initial bond value (500) from this to get the total interest earned (1,255). We then divide this interest by two (627.5) and add it to the initial bond value (500) to get the value after 20 years (1,127.5). We then multiply this by two (2,255) and subtract the total interest earned (1,755) to get the final value (500). This is double the initial bond value, so the bond will be worth $1,000 when it matures.

4 jars Lorraine can fill with tomatoes as in step with the given unit conversion.

The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

Given this, Lorraine prepared a 1.5-gallon pot filled with tomatoes to be canned in jars. Each jar will hold 1.5 quarts of tomatoes

Since 1 gallon is equal to 4 quarts.

Total tomatoes Lorrain has = 1.5 gallons = 1.5 * 4 quarts

Total tomatoes Lorrain has = 6 quarts

Since one jar can only fit 1.5 quarts of tomatoes

Answer:

To find the exact value of csc(theta) in simplest radical form, we first need to determine the coordinates of the point on the terminal side of the angle in standard position.

Since the terminal side passes through the point (-2,1), we know that the point is on the line y = 1. To find the exact value of csc(theta), we need to find the distance between the point (-2,1) and the origin (0,0). This distance is given by the expression sqrt((-2)^2 + 1^2) = sqrt(5).

Therefore, csc(theta) = 1/sin(theta) = 1/sqrt(5)

a) The upper bound for the perimeter of the rectangle is 42.4 m.

b)The lower bound for the area of the rectangle is 83.21 cm².

We have, The lengths of the rectangle have been measured to the nearest tenth of a metre. So, degree of accuracy of measurements = 1/10 m = 0.1 m

We need to work out the upper and lower bounds for each side, when side length = 15.8 m and width = 5.2 m

Upper bound of length = 15.8 + 0.1

= 15.9 m

Lower bound of length = 15.8 - 0.1 = 15.7

Upper bound of width = 5.2 + 0.1 = 5.3

Lower bound of width = 5.2 - 0.1 = 5.1

For lower bound of Area :

We know the area of a rectangle is equals to product of width and length, so for the upper bound for the area we multiply the lower bound fo width and the lower bound of length together:

So lower bound of Area of rectangle

= 15.7× 5.1 = 83.21 cm²

For upper bound of Perimeter :

We know that the perimeter of rectangle is equals to two times of sum of each side of the rectangle, so for the upper bound for the perimeter we use the upper bound of each side:

2( 15.9 + 5.3) = 2× 21.2 = 42.4 m

Hence, the required area is 83.21 cm² and perimeter 42.4 m .
