Hey, I need some help on this question

Answer:

3 minutes; 27 minutes; 30 minutes

Step-by-step explanation:

Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.

Therefore,

[tex]x + 9x + 10x = 1 \: hour \\ \\ 20x = 60 \: minutes \\ \\ x = \frac{60 \: minutes}{3} \\ \\ x = 3 \: minutes \\ \\ 9x = 9 \times 3 = 27 \: minutes \\ \\ 10x = 10 \times 3 = 30 \: minutes[/tex]

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:

3 minutes; 27 minutes; 30 minutes

Answer:

B. the distributive property

Step-by-step explanation:

Distributive property can be used to expand the expression -2(3/4x+7).

When that property is used, we need to distrubute the monomial to the binomial which is the two terms.

[tex] - 2( \frac{3}{4} x + 7) \\ \Longrightarrow \boxed{- 2( \frac{3}{4} x) + - 2(7)} [/tex]

Answer:

T = 162 minutes

Step-by-step explanation:

Given that,

Jill can run 5 miles in 45 minutes.

We need to find how long will it take her to run 18 miles.

[tex]5\ miles =45\ minutes\\\\1\ mile=(\dfrac{45}{5})\ minute\\\\1\ mile =9\ minute[/tex]

So,

18 miles = (18×9) minutes

= 162 minutes

Hence, 162 minutes will be taken by her to run 162 minutes.

Answer:

If you wanted to simplify the equation:

9y - 30 = 6

If you wanted to solve for y:

y = 4

Step-by-step explanation:

3(3y - 10) = 6

9y - 30 = 6

Add 30 to both sides of the equation:

9y - 30 + 30 = 6 + 30

Simplify:

9y = 6 + 30

9y = 36

Divide both sides of the equation by 9:

9y ÷ 9 = 36 ÷ 9

Cancel terms that are in both the numerator and denominator:

y = 36 ÷ 9

y = 4

Answer:

  no real solutions; k = ±i(2/3)√15

Step-by-step explanation:

If k is one of the roots, then substituting it for x will satisfy the equation:

  k -4k -20/k = 0

Multiplying by k gives ...

  -3k^2 -20 = 0

  k^2 = -20/3 = -6 2/3

There are no real values of k such that this is true.

__

If we allow k to be imaginary, then ...

  k = ±i√(20/3) = ±i(2/3)√15

Possible imaginary values of k are ±(2/3)√15.

Step-by-step explanation:

complementary angle is 90 degrees

so angle t and s are complementary

measure of angle t is 72 degrees

so measure of angle s will be 90 degrees minus 72 degrees which gives 18 degrees

so measure of angle s is 18 degrees

angle r and angle s are supplement which means their sum is 180 degrees

so measure of angle r will be 180 minus 18 which gives 162

so measure of angle r is 162 degrees

we need to find measure.of angle r minus measure.of angle s

so 162 minus 18 which gives 14r

Answer:

13.8 ounces of salt

Step-by-step explanation:

A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

Step 1

Note that:

1 shaker = 0.6 ounces of salt

8 shakers = x

Cross Multiply

x = 8 × 0.6 ounces of salt

x = 4.8 ounces of salt

Step 2

The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

This is calculated as:

18.6 ounces of salt - 4.8 ounces of salt

= 13.8 ounces of salt

Using the equation y = abx , substitute both of your given points into that equation.

2 = ab2 and 4 = ab3 Solve each equation for a.

2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3

Cross multiply: 2b3 = 4b2 Divide both sides by b2

2b = 4 a = 2/4 = 1/2

b = 2

Answer:

-x^5 + 7x⁴ + 8x² - 9x - 5

Step-by-step explanation:

For the question given:

Rocks traded, sold or given away are denoted by negative values, '-' while rocks bought or purchased are diniywd as positive, '+'

Starting = 8x² ;

Purchase = + 7x⁴ ;

Trades = - x^5

Gives away = - 9x

Sells = - 5

The number of rocks Emily now has :

8x² + 7x⁴ - x^5 - 9x - 5

In standard form:

Arrange in order of power :

-x^5 + 7x⁴ + 8x² - 9x - 5

Answer:

[tex]D) 0.5x^3y + 4x^2 y^2 - 2xy^3[/tex]

Step-by-step explanation:

Set up an equation to model the situation,

[tex](-0.5xy)(x^2 + 8xy - 4y^2)[/tex]

Distribute, multiply each term in the parenthesis with the term outside of the parenthesis. Don't forget the laws of exponents, when one multiplies two exponents, with the same base, then one adds the two exponents. A number with no exponential term is two the first degree meaning that it is to the power of one.

Answer:

The jumping dolphin --  changes

The flying seagull -- same

The octopus --  same

Step-by-step explanation:

The distance of the Albatross from the sea surface when compared to the vertical distance from the eyes of the :

The jumping dolphin :

As the dolphin jumps out from the sea, the vertical distance of the albatross from the surface seems to be decreasing and then increasing as seen by the jumping dolphin.

The flying seagull :

The distance of the albatross is at the same height as seen by the seagull since it is flying at the same level, i.e. at the level of the sea surface

The octopus :

The octopus remains at the same depth below the water surface. So the distance of the albatross for the octopus remains the same at 5 m above the ocean surface.

The probability of 2 seniors out of 20 serving in the military is ²⁰C₂(0.15)²(0.85)¹⁸.

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

As it is given that 15% of the seniors in a large high school enter military

service upon graduation. Therefore, the probability of a large high school entering the military services will be 0.15. Similarly, the probability of a senior from a large high school not joining entering the military can be written as,

[tex]q = (1-p)\\\\q = 1-0.15\\\\q=0.85[/tex]

Now, the probability of 2 seniors out of 20 serving in the military will be,

[tex]P(x) = ^nC_x p^xq^{(n-x)}\\\\P(x=2) = ^{20}C_2 \times (0.15)^2 \times (0.85)^{(20-2)}\\\\P(x=2) = ^{20}C_2 \times (0.15)^2 \times (0.85)^{(18)}[/tex]

Hence, the probability of 2 seniors out of 20 serving in the military is ²⁰C₂(0.15)²(0.85)¹⁸.
