Answer:

50%

Step-by-step explanation:

The square  is spilt into 2 equal pieces, one out of the 2 is shaded therefore 1/2 is shaded. The decimal to represent the shaded area would be 0.5, as 1 times 1/2 = 0.5. As a percent the shaded area represents 50% as 1/2 times 100 (per cent = per hundred) is equivalent to 50.

Answer:

x ≤ 3.5 gigabytes

Step-by-step explanation:

Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month.

Let us represent the number of gigabytes = x

Hence, our Equation is:

$56 + $4 × x ≤ $70

56 + 4x ≤ 70

Collect like terms

4x ≤ 70 - 56

4x ≤ 14

x ≤ 14/4

x ≤ 3.5 gigabytes

Therefore, the number of gigabytes Anthony can use while staying within his budget is less than or equal to 3.5 gigabytes

Answer:

A. 4.50 B. 1 : 3

Step-by-step explanation:

A.

First, think of Toby's money as 1/6x (x referring to the total amount of money) and Daoud's money as 1/2x.

It states that Toby gets 1.50, which means that 1/6x = 1.50.

To find what x is, multiply both sides by 6.

1/6x * 6 = 1.50 * 6

x = 9

Now that we know how much money there is in total, we can solve for Daoud's money. Daoud has 1/2x. We can substitute x for 9 and solve for Daoud's money.

1/2(9)

4.50

Daoud has 4.50.

B.

The problem states that Elsa gets the remaining money.

9 - (1.50 + 4.50)

9 - 6

3

Elsa gets 3.00.

Now, you can use turn solve the ratio of Toby's money and Elsa's money.

Answer:

47.5

hope this helped

Answer:

47.5

Step-by-step explanation:

To find the answers, we need to calculate the number of steps each player takes before they are unable to continue:

For Amar:

5 stairs up and 2 stairs down per turn

Net gain of 3 stairs per turn

It will take 32 turns to reach 96 stairs (32 * 3 = 96)

In the 33rd turn, Amar will climb 5 stairs and reach 100 stairs.

For Akbar:

7 stairs up and 2 stairs down per turn

Net gain of 5 stairs per turn

It will take 19 turns to reach 95 stairs (19 * 5 = 95)

In the 20th turn, Akbar will climb 7 stairs and reach 100 stairs.

For Anthony:

10 stairs up and 3 stairs down per turn

Net gain of 7 stairs per turn

It will take 14 turns to reach 98 stairs (14 * 7 = 98)

In the 15th turn, Anthony will climb 10 stairs and reach 100 stairs.

I) The players will meet on the same stair whenever they end up on a stair whose number is the same for any two players. To find out the number of times they meet on the same stair, we need to calculate the lowest common multiple (LCM) of the number of turns taken by each player to reach 100 stairs.

Amar takes 33 turns

Akbar takes 20 turns

Anthony takes 15 turns

LCM(33,20,15) = 660

Therefore, they will meet on the same stair 660/33 + 660/20 + 660/15 = 20 + 33 + 44 = 97 times.

II) Anthony takes the least number of steps to reach near hundred, as he only needs 15 turns to reach 98 stairs.

Answer:

the standard form of y=5x+0.5 is B=-5x+y=0.5

Answer:

the answer is 5x - y= -0.5

====================================================

Work Shown:

5% = 5/100 = 0.05

5% of 42 = 0.05*42 = 2.10

tax = $2.10

total cost including tax = $42 + $2.10 = $44.10

----------

An alternative is to multiply 42 by 1.05 to get

1.05*42 = 44.10

We get the same answer. The 1.05 refers to 1 + 0.05 where the "1" is 100% and the 0.05 is 5%, so the two combine to 105%, meaning the total cost is 105% of the cost before tax is considered.

Chronic dehydration might impair your kidney function and raise your risk of kidney stones. Water also helps with normal bowel function, muscular performance, and clean, young skin.

Let's assume that the total number of students in the school is "x".

40 percentage  of the students at the school play at least one sport. So, the number of students who play at least one sport is 0.4x.

We also know that the number of students who play at least one sport is 102. Therefore, we can write:

0.4x = 102

Move 0.4 to the right hand side of the equation

x = 102 / 0.4

To identify the surface with the given vector equation, we need to examine the coefficients of the variables in each component of the equation. In this case, we have:

r(u,v) = (u+v)i + (3-v)j + (1+4u+5v)k

This represents a vector-valued function in three-dimensional space. To see what surface it describes, we can look at the coefficients of u, v, and constants in the equation.

The coefficient of u is 4 in the k-component, so the surface will have a slope in the u-direction. The coefficient of v is 5 in the k-component, so the surface will also have a slope in the v-direction. The constant term is 1 in the k-component, so the surface will be offset by 1 unit in the positive k-direction.

Based on this information, we can conclude that the surface described by the given vector equation is a plane with a slope in the u and v directions, and is offset from the origin by 1 unit in the positive k-direction.

After performing the calculations, the approximation of the area under the curve using a left Riemann sum with 4 equal subintervals is approximately 4.599. Therefore, the correct answer is (a) 4.599.

To approximate the area under the curve y = e^x over the interval [-1, 1) using a left Riemann sum with 4 equal subintervals, we need to calculate the width of each subinterval and evaluate the function at the left endpoint of each subinterval.

The width of each subinterval, Δx, is calculated as the difference between the endpoints of the interval divided by the number of subintervals. In this case, Δx = (1 - (-1)) / 4 = 2 / 4 = 0.5.

Next, we evaluate the function at the left endpoint of each subinterval, which means substituting the left endpoint values (-1, -0.5, 0, 0.5) into the function y = e^x.

Using a calculator, we can calculate the function values at each left endpoint and then sum up the areas of the rectangles formed by multiplying the function values by the width Δx.

The slope of the line shown in the graph is __2/3__

and the y-intercept of the line is __6___

The general linear equation is written as follows:

y = ax + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = 6, then we can write the line as:

y = ax + 6

The line also passes through the point (-9, 0), replacing these values in the line we will get:

0 = a*-9 + 6
