What's 2x2? This is a very hard question and i need help.

Answer:

√430 or 20.74

Step-by-step explanation:

√430

Prime factorize 430

√2 · 5 · 43

There are no pairs to take out of the root, so the most simplified form of √430 is √430.

If you want the decimal form, it is 20.74

Answer:

How much do the adukts weigh?

Step-by-step explanation:

Answer:

−6(a+8)

=(−6)(a+8)

=(−6)(a)+(−6)(8)

=−6a−48

Step-by-step explanation:

multiply -6 x a to get -6a and multiply -6 x 8 to get -48 so -6a-48

Answer:

9.3 x 8.5 = 79.05

7.6 x 2.4 = 18.24

an easier way to multiply decimals is to take away decimals and add later

example: 9.3x8.5 > 93x85 = 7905 since there are two places behind the decimal add that many to the solution 7905 > 79.05

Answer:

Grace scored 9 points in her first game.

Step-by-step explanation:

In her first game, she scored n points.

She scored 8 more points in her second game than in her first

So n + 8.

3 fewer points in her third game than in her second

So n + 8 -3 = n + 5

11 more points in her fourth game than in her third

n + 5 + 11 = n + 16

A total of 25 points in her fourth game.

This means that:

n + 16 = 25

n = 9

So

Grace scored 9 points in her first game.

Answer:

6 for 76 and 5 for 94

Step-by-step explanation:If you divide 76 with 6 the quotient will be 12 and the remainder will be 4 and if you divide 94 by 5 the quotient will be 18 and the remainder will be 4. Thank me later .

The largest number which divides 94 and 76, leaving a remainder of 4. is 18.

It is required to find the largest number.

A number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.

Given:

we have to  find the largest number which divide 94 and 76 leaving remainder 4 in each case.

According to given question we have

so let us subtract 4 from 94 and 76.

⇒ 94−4=90

⇒ 76−4=72

now lets find the HCF

⇒ prime factorization of 90 = 2 × 3 × 3 × 5

  prime factorization of 72 = 2 × 2 × 2 × 3 × 3

now lets take out the common factors from both the cases

⇒ 2,3 and 3

x=2*3*3=18

∴ 18 is the number which will divide 94 and 76 leaving remainder 4 in each case.

Therefore, the largest number which divides 94 and 76, leaving a remainder of 4. is 18.

Answer:

13.125

Step-by-step explanation:

Since the triangles are congruent, you would get the equation 4z-7=11z-112.

Then, you would subtract 4z from each side, leaving behing -7=8z-112. Then, you would add 112 to each side, getting 105=8z. Divide both sides by 8, and your answer is z=13.125

Answer: I believe the answer would be 5.1 ounces...

Step-by-step explanation:

To get this answer I used a proportion and transformed pounds into ounces. 1lb=16oz

x/16= 2.55/8

Cross multiply....

8x=40.8

And simplify!

x=5.1

So for $8 you can get a pound, for $2.55 you can get 5.1 ounces (or 5 ounces if needed in whole numbers)

Hope this helps! Good luck! (:

Answer:

Percent decrease in population = 12%

Step-by-step explanation:

Given that:

Population of city = 160,000

Population of city after several years = 140,800

Difference= 160000 - 140800 = 19200

Percent decrease = [tex]\frac{Difference}{Population} * 100[/tex]

Percent decrease = [tex]\frac{19200}{160000}*100[/tex]

Percent decrease = 0.12 * 100

Percent decrease = 12%

Hence,

Percent decrease in population = 12%

Answer:

They can make 10 different groups of three.

Step-by-step explanation:

The order in which the people are in the car is not important, so we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different groups of three can the five of them make?

Combinations of 3 from a set of 5. So

[tex]C_{5,3} = \frac{5!}{3!(5-3)!} = 10[/tex]

They can make 10 different groups of three.

Answer:

length of rectangular box = 2[w] + 5

length of rectangular box = 35 cm

Step-by-step explanation:

Given:

length (l)

width (w)

Perimeter = 100 centimetre

Computation:

Part A;

length of rectangular box = 2[width] + 5

length of rectangular box = 2[w] + 5

Part B;

Perimeter = 2[l+w]

100 = 2[2w + 5 + w]

100 = 6w + 10

w = 15 cm

length of rectangular box = 2[w] + 5

length of rectangular box = 2[15] + 5

length of rectangular box = 35 cm

Answer:

Longer than 27.7 minutes.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 25, \sigma = 4[/tex]

The slowest quarter of customers will require longer than how many minutes (to the nearest tenth) for a simple haircut?

Longer than the 100 - 25 = 75th percentile of times, which is X when Z has a pvalue of 0.75. So X when Z = 0.675. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 25}{4}[/tex]

[tex]X - 25 = 4*0.675[/tex]

[tex]X = 27.7[/tex]

So

Longer than 27.7 minutes.

Answer:

C(5, -3)

Step-by-step explanation:

Given the equation of circle;

x² + y² - 10x + 6y - 2 = 0

The general equation for a circle is given by the formula;

x² + y² + 2gx + 2fy + c = 0

Where the center is C(-g, -f)

To find the center, we would compare the two equations;

For the value of g.

2gx = -10x

2g = -10

g = -10/2

g = -5

To find the value of f.

2fy = 6y

2f = 6

f = 6/2

f = 3

Therefore, the center C(-g, -f) = (-(-5), -(3))

C(-g, -f) = C(5, -3).
