approximate the number using a calculator 6^2.8

Solution is given in attachment below.

Answer:

Bus drop him off 64 miles far from the school.

Explanation:

 Total distance traveled by Nigel from Home to school each day = 312 miles

 Distance from bus stop to his home = 14 miles

Distance traveled by Nigel on the city bus = 234 miles.

Distance from bus drop off position to school = X miles

We have Total distance traveled by Nigel = 14+234+X = 248+X

Equating both total distances

          248+X = 312

            X = 64 miles.

 So bus drop him off 64 miles far from the school.

Final answer:

The percent drop in temperature from 80°F to 70°F is calculated as (10°F / 80°F) × 100%, which equals 12.5%.

Explanation:

To find the percent drop in temperature from 80°F to 70°F, we need to calculate the decrease in temperature and then express that decrease as a percentage of the original temperature. The decrease in temperature is 80°F - 70°F = 10°F. To find the percent drop, we use the formula for percentage change, which is (Change/Original) × 100%.

Therefore, the percent drop = (10°F / 80°F) × 100% = 12.5%. So, the temperature dropped by 12.5% from 80°F to 70°F.

Final answer:

To find the percent drop in temperature from 80°F to 70°F, calculate the difference between the temperatures and divide by the original temperature, then multiply by 100%. The result is a 12.5% decrease in temperature.

Explanation:

The question asks to find the percent drop in temperature when it drops from 80°F to 70°F. To calculate this, we use the formula for percent decrease, which is (original value - new value) / original value × 100%. Applying this formula, the original temperature is 80°F, and the new temperature is 70°F.

(80°F - 70°F) / 80°F × 100% = 10°F / 80°F × 100% = 0.125 × 100% = 12.5%.

Therefore, the temperature dropped by 12.5% when it fell from 80°F to 70°F.

Solution:

The given complex expression is,

→(5+3 i) - (5+3 i)(5-5 i)

Keep in mind, i=√-1, i²= -1

=(5 + 3 i)[1- (5-5 i)]

=(5 + 3 i)[1-5+ 5 i]

= (5 + 3 i)[-4 + 5 i]

=5 × (-4 + 5 i) + 3 i×(-4 + 5 i)→→Used the identity, (a+b)×(c+d)=a×(c+d)+b×(c+d), Also Used distributive property of multiplication over addition and subtraction.

= -20 + 25 i-12 i +15 i²

= - 20 + 13 i-15

= -35 + 13 i

Answer:

Option B. 0.75 gallons is the right answer.

Step-by-step explanation:

Let the load of dishwasher used in house A = x gallons

Let the load of dishwasher used in house B is = y gallons

and similarly we assume for house C = z gallons

Now from the given question

On Friday amount of water used in all three houses = 17.5 gallons

From the table we will make the equation

x + 2y + 2z = 17.5-----(1)

For Saturday

2x + 3y + 4z = 31.5 ----(2)

For Sunday

2x + 2y + 3z = 24.75 -----(3)

By subtracting equation 3 from 2

y + z = 31.5 - 24.75 = 6.75 ------(4)

Equation (1) multiplied by 2 - equation (2)

2×(x + 2y + 2z) - (2x + 3y + 4z) = 17.5×2 - 31.5

y = 35 - 31.5 = 3.5

By putting y = 3.5 in the equation (4)

z = 6.75 - 3.5 = 3.25

By putting y = 3.5 and z = 3.25 in the equation (1)

x + 7 + 6.5 = 17.5

x = 17.5 - 13.5 = 4

Now the difference between load of dishwasher that uses least water and the most.

x - z = 4 - 3.25 = 0.75 gallons

Option B is the right answer.

Answer:

Option B. 0.75 gallons is the right answer.

Answer:

option 2=11/20  is the answer.

Step-by-step explanation:

given that there are 20 cards numbers 1,2... 20.

A card is randomly drawn.

We have to find the probability of drawing either 1 or even card.

P(drawing even card) = no of even cards/total cards = 10/20= 0.5

P(drawing one) = no of 1's/total cards = 1/20 = 0.05

P(drawing both one and even card) = 0 (since impossible)

Hence P(drawing even or one) =0.5+0.05-0

=0.55

= 11/20

Hence option 2 is the answer.

Answer : 11/20

There are 20 cards labeled from 1 to 20 in a bag. A card is randomly selected from the bag.

Total number of outcomes = 20

outcomes of an even number ={2,4,6,8,10,12,14,16,18,20}

So number of outcomes of even number = 10

outcomes of a 1 ={1}

So number of outcomes of a 1 = 1

Number of outcomes of even number and a 1 = 10+1 = 11

Probability ( any event) =number of favorable outcomes divide by total  number of outcomes

Probability (getting an even number or a 1) = [tex]\frac{11}{20}[/tex]

1) The probability of getting a queen is 187/10000 which is 0.0187 = 1.87%

2) The probability is 449 / 479 which is 0.937 = 93.7%

You may need to round the answers. It doesn't say if they need to be rounded or not.

Hi ShadowHawk,

1) If you conduct an experiment and randomly pull a card from a deck of cards 10,000 times, getting a Queen of Hearts 187 times, what is the experimental probability of drawing a Queen of Hearts the next time?

187/10,000 = 1.87% = 1.9%

2) If a kicker has kicked a ball 479 times for the extra point and scored the point 449 times, what is the experimental probability of the kicker making the next field?

449/479 = 93.7% = 94%

Answer:

  6

Step-by-step explanation:

The greatest common factor (GCF) of 18, 24, and 30 is 6.

Victor can make at most 6 bags with equal numbers of each type of cookie.

_____

18 = 6×3

24 = 6×4

30 = 6×5

One way to look for the GCF is to consider the differences between the numbers. The smallest difference between any pair is 6, which also divides all of the numbers evenly. Hence 6 is the GCF.

By finding the greatest common divisor (GCD) of the counts of each type of cookie (30, 18, 24), it is determined that Victor can make 6 identical bags for the bake sale.

To determine the greatest number of bags Victor can make, we need to find the greatest common divisor (GCD) of the counts of each type of cookie: 30 chocolate chip cookies, 18 peanut butter cookies and 24 sugar cookies. The GCD is the largest number that exactly divides all these counts.

First, list the divisors of each number:

Find the highest number that appears in each list. The highest common factor of 30, 18, and 24 is 6, so Victor can make a total of 6 equal bags with each type of cookie.

Aiden spent $22.20 on 60 candles. His sister spent $54.40 on 170 candles, $32.20 more than Aiden.

Let's break this down step by step:

a. To find out how much Aiden spent on candles, we multiply the number of candles he bought (60) by the price per candle ($0.37):

Total cost for Aiden = 60 × $0.37 = $22.20

So, Aiden spent $22.20 on candles.

b. Aiden's sister bought 170 candles and paid $0.05 less per candle than Aiden did. This means she paid $0.37 - $0.05 = $0.32 per candle.

To find out how much Aiden's sister spent on candles, we multiply the number of candles she bought (170) by the price per candle ($0.32):

Total cost for Aiden's sister = 170 × $0.32 = $54.40

So, Aiden's sister spent $54.40 on candles.

c. To compare who spent more on candles, we simply compare the total costs. Aiden spent $22.20 and his sister spent $54.40.

Aiden's sister spent more. To find out how much more she spent, we subtract Aiden's total from his sister's:

$54.40 - $22.20 = $32.20

So, Aiden's sister spent $32.20 more on candles than Aiden did.

The complete question is here:

To prepare for a wedding, Aiden bought 60 candles. He paid $0.37 for each candle. His sister bought 170 candles at a sale where she paid $0.05 less for each candle than Aiden did.

a. How much did Aiden spend on candles?

b. How much did Aiden's sister spend on candles?

c. Who spent more on candles? How much more?

The fencing that is needed to enclose the garden is 36 meters.

Let the width be represented by x.

Let the length be represented by x+2.

The area is given as 80m².

Therefore, the length and width will be calculated thus;

x(x + 2) = 80

x² + 2x - 80 = 0

x² + 10x - 8x - 80 = 0

x(x + 10) - 8(x + 10) = 0

x - 8 = 0

x = 8

The width is 8 meters and the length is 10m.

The perimeter will be:

= 2(8m + 10m)

= 2 × 18m

= 36m

Answer:

[tex]x = \frac{2}{3} + \frac{\sqrt{10} }{3} , x = \frac{2}{3} - \frac{\sqrt{10} }{3}[/tex]

Step-by-step explanation:

Multiplying the coefficient of x by the constant to get:

3 x (-2) = -6

Find factors of -6 that equal the middle term -4.

Since, no such factors can be found so we can solve the equation by completing the square.

To complete the square, divide the equation by the coefficient of x^2 which is 3 to get:

[tex]x^{2} - \frac{4}{3} x - \frac{2}{3} = 0[/tex]

[tex]x^{2} - \frac{4}{3} x = \frac{2}{3}[/tex]

Now divide the coefficient of x by 2 and add the square of the result to both sides of the equation:

[tex]x^{2} - \frac{4}{3} x + (-\frac{2}{3} )^{2} = \frac{2}{3} +  (-\frac{2}{3} )^{2}[/tex]

[tex](x - \frac{2}{3} )^2 = \frac{2}{3} + \frac{4}{9}[/tex]

[tex](x - \frac{2}{3} )^2 = \frac{4}{9}[/tex]

[tex]\sqrt{(x - \frac{2}{3} )^2} = \sqrt{\frac{4}{9} }[/tex]

[tex]x - \frac{2}{3} = \sqrt{\frac{10}{9} }[/tex] , [tex]x - \frac{2}{3} = -\sqrt{\frac{10}{9} }[/tex]

[tex]x = \frac{2}{3} + \frac{\sqrt{10} }{3} , x = \frac{2}{3} - \frac{\sqrt{10} }{3}[/tex]
