What percent of 88 is 154?

Answer:

a = (D+f) * g

Step-by-step explanation:

We want to isolate a

a/g -f =D

Add f to each side

a/g -f+f = D+f

a/g = D+f

Multiply each side by g

a/g *g = (D+f) * g

a = (D+f) * g

[tex]\dfrac{a}{g}-f=D\qquad\text{add f to both sides}\\\\\dfrac{a}{g}=D+f\qquad\text{multiply both sides by }\ g\neq0\\\\\boxed{a=g(D+f)}\qquad\text{use distributive property}\\\\\boxed{a=Dg+fg}[/tex]

One chocolate bar costs approximately 0.91 dollars.

Let x be the cost of one chocolate bar.

Given that 11 chocolate bars cost 10 dollars, we set up a proportion:

11 bars / 10 dollars = 1 bar / x dollars

To get cost of one chocolate bar (x), we cross-multiply:

11 * x = 10 * 1

11x = 10

x = 10 / 11

x ≈ 0.91 dollars.

Answer:

30%

Step-by-step explanation:

there is a 60% chance of getting a red marble each time. You need to choose a ball twice. 60/2=30. therefore there is a 30% chance of getting two reds.

Final answer:

To find the probability of drawing two red marbles with replacement from a jar of six red and four blue marbles, we multiply the probability of drawing a red marble (3/5) by itself, resulting in 9/25.

Explanation:

The question asks for the probability that both marbles will be red when two marbles are chosen one at a time with replacement from a jar containing six red marbles and four blue marbles.

To find this, we calculate the probability of drawing a red marble, and since we replace the marble each time, this probability does not change with each draw. With six red marbles out of a total of 10, the probability of drawing a red marble on the first draw is 6/10 or 3/5. Since we replace the marble after each draw, the probability remains the same for the second draw.

Therefore, the probability of drawing two red marbles in a row is (3/5) * (3/5), which is 9/25.

Answer:

The average rate is 35 miles per hour

Step-by-step explanation:

To get from town A to town B takes 3 hours.  The distance is 100 miles

To get from town B to  town c takes 1 hours.  The distance is 40 miles

To find the average rate , we need to find the total distance and divide by the total time

Total distance = 100 + 40 = 140 miles

Total time = 3 hrs + 1 hr = 4 hours

distance = rate * time

140 miles = rate * 4 hours

140/4 = rate

35 = rate

The average rate is 35 miles per hour

Answer:no it is not reasonable

Step-by-step explanation: take the Max average number and multiply it by six, it only reaches 10.26

John's estimation of 28 units of electricity usage for the six houses on Philips Road is considered reasonable since it falls within the calculated possible range of 18.96 to 40.08 units.

To verify John's estimate, we need to consider the maximum and minimum electricity usage for the houses based on their given range of usage and time. On the high end, each house could use 1.71 units for 4 hours, which gives a total of 6.84 units per house.

Therefore, the total usage for all six houses would be 40.08 units (6 x 6.84 = 40.08). On the low end, each house could use 1.58 units for 2 hours, amounting to 3.16 units per house. The total for all houses would then be 18.96 units (6 x 3.16 = 18.96). Given this, John's estimate of 28 units falls within this range and can be considered reasonable.

Step-by-step explanation:

The pentagon has 5 interior angles that add up to 360. To find the angle of rotational symmetry, divide 360 by 5 (you get 72). So if you rotated the shape 72 degrees, it will map onto itself. 72 times 2 is 144, and that's rotating the shape 72 degrees twice, so it will stay the same.

A mathematical transformation that carries a pentagon onto itself is a rotation by 72 degrees or a multiple of 72 degrees, which are the internal angles of a regular pentagon.

The question is referring to certain mathematical transformations that can be applied to shapes, specifically a pentagon. A transformation that will carry a shape onto itself, maintaining its form, is a symmetry operation. For a pentagon, one of these transformations could be a rotation. For example, if you rotate the pentagon 72 degrees or a multiple of 72 degrees (such as 144, 216, 288 degrees, etc.), it will land on itself because 72 degrees represents each internal angle of a regular pentagon.

Answer: You can get 6 pounds of apples and approximately 19 apples.

Step-by-step explanation:

There are 16 ounces per pound so 6 pounds is 96 ounces

96/5 = 19.2

You can buy 6 pounds of apples for 9, which is approximately 19 apples.

1. First, let's find out how much one pound of apples costs. Since two pounds cost $3.00, one pound would cost half of that, which is $1.50.

2. Now, if one pound costs $1.50, we can find out how many pounds of apples you can buy for $9 by dividing $9 by the cost per pound: [tex]\( \frac{9}{1.50} = 6 \)[/tex]. So, you can buy 6 pounds of apples for $9.

3. Since 1 pound equals 16 ounces, 6 pounds equal [tex]\( 6 \times 16 = 96 \)[/tex]ounces.

4. If one apple is approximately 5 ounces, then the number of apples you can buy for 96 ounces is [tex]\( \frac{96}{5} \).[/tex]

5. Performing the division, [tex]\( \frac{96}{5} = 19.2 \)[/tex]. Since you can't buy a fraction of an apple, you'd round down to the nearest whole number.

6. So, you can buy approximately 19 apples for $9.

Here's the calculation step by step:

1. Cost per pound: [tex]\( \frac{3.00}{2} = 1.50 \)[/tex] dollars per pound.

2. Pounds you can buy for $9: [tex]\( \frac{9}{1.50} = 6 \)[/tex] pounds.

3. Total ounces: [tex]\( 6 \times 16 = 96 \)[/tex] ounces.

4. Apples you can buy: [tex]\( \frac{96}{5} = 19.2 \)[/tex](rounded down to 19 apples).

Final answer:

The number in question is 70, found by solving the equation 1/2 * x - 25 = 10.

Explanation:

To find a number where half of that number, subtracted by 25, equals 10. We can set up an equation to represent this: 1/2 * x - 25 = 10, where 'x' is the number we are trying to find. To solve for 'x', we first add 25 to both sides of the equation, which gives us 1/2 * x = 35. Then, to isolate 'x', we multiply both sides by 2, resulting in x = 70. Therefore, the number is 70.

Final answer:

To find the number, isolate the variable by performing inverse operations. The number is 70.

Explanation:

To find the number, we need to translate the given information into an equation. Let's assume the number is x. The equation can be written as:

1/2x - 25 = 10.

To isolate the variable x, we first add 25 to both sides of the equation:

1/2x - 25 + 25 = 10 + 25.

This simplifies to 1/2x = 35.

Next, we multiply both sides of the equation by 2 to undo the division by

1/2: 2 × (1/2x) = 2 × 35.

The 1/2 cancels out on the left side, leaving us with x = 70.

Therefore, the number is 70.

we are given cube

Let's assume edge of cube =x

so, volume of cube will be

[tex]V(x)=x^3[/tex]

we are given

V=125000

so, we can find 'x'

[tex]125000=x^3[/tex]

[tex]x=50[/tex]

So,

[tex]a=50[/tex]

now, we can use linear approximation formula

[tex]L(x)=V(a)+(x-a)V'(a)[/tex]

[tex]L(x)=V(a)+(\Delta x)V'(a)[/tex]

we have

[tex]\Delta x=0.1[/tex]

we can plug a=50

[tex]L(x)=V(50)+(0.1)V'(50)[/tex]

[tex]V(x)=x^3[/tex]

we can find derivative

[tex]V'(x)=3x^2[/tex]

now, we can plug x=50

[tex]V'(50)=3(50)^2[/tex]

[tex]V'(50)=7500[/tex]

now, we can plug these values

and we get

[tex]L(x)=V(50)+(0.1)\times 7500[/tex]

[tex]L(x)=V(50)+750[/tex]

[tex]L(x)-V(50)=750[/tex]

so, error is

[tex]error=750[/tex]

now, we can find percentage error

Percentage is

graph-C........Answer

Final answer:

To estimate the percentage error in volume, use the tangent line approximation and find the derivative of the volume function. Then divide the change in volume by the actual volume and multiply by 100%.

Explanation:

To estimate the percentage error in volume, we need to find the derivative of the volume function with respect to the length of one edge of the cube. The volume of a cube is given by V = a^3, where a is the length of one edge of the cube. So, the volume function is V = a^3.

Using the tangent line approximation, we can approximate the change in volume as the derivative of the volume function multiplied by the change in length of one edge of the cube. The derivative of the volume function is dV/da = 3a^2. The change in length of one edge is ±0.1 cm. So, the change in volume is approximately dV = (3a^2) * (±0.1 cm).

To find the percentage error in volume, we divide the change in volume by the actual volume and multiply by 100%. The actual volume is 125,000 cm^3. So, the percentage error in volume is approximately [(3a^2) * (±0.1 cm)] / (125,000 cm^3) * 100%.
