Ganesh uses 1.6 gallons of paint for his bedroom walls. For his study, he uses 0.7 times the amount of paint he uses for his bedroom. How much paint does Vanesh use to paint his study?

Answer:

1  69/145 cups

Step-by-step explanation:

We can use ratio's to solve this problem.  We will put water over time

214 cups           x cups

--------------- = --------------

145 hours        1 hours

Using cross products

214 *1 =145 x

Divide both sides by 125

214/145 = 145x/145

214/145 = x

145 goes into 215 1 time with 69 left over

1 69/145

Final answer:

Bailey spends more time getting dressed, which is 1/2 of an hour (30 minutes), whereas she spends 1/4 of an hour (15 minutes) eating breakfast.

Explanation:

The question is asking which activity Bailey spends more time on in the morning: getting dressed or eating breakfast. Since Bailey has an hour to get ready, 3/6 of an hour is spent getting dressed, and 1/4 of an hour is spent eating breakfast.

First, we simplify the fraction for getting dressed, as 3/6 can be reduced to 1/2. Thus Bailey spends 1/2 hour or 30 minutes getting dressed. To find how much time is spent eating breakfast, we calculate 1/4 of an hour, which is 15 minutes.

Comparing the two, we see that Bailey spends more time getting dressed (30 minutes) than eating breakfast (15 minutes).

Answer:

equilateral triangle, kite, regular pentagon, regular hexagon

a hexagon has rotational symmetry. Furthermore, the angle of rotation is 60° and since there are six copies of 60° in 360° (360 ÷ 60 = 6), we have that the order of rotation of a regular hexagon is six.

Answer:

30.85%

Step-by-step explanation:

Assume that a set of test scores is normally distributed with a mean of 70 and a standard deviation of 10

mean = 70 and SD= 10

To find percentile we use z-score value

z value can be find using formula

[tex]z= \frac{x-mean}{SD}[/tex]

[tex]z= \frac{65-70}{10}[/tex]

z=-0.5

Now we use z- score table to find the value when z=-0.5

P(x=65) = 0.3085

To find percentile we multiply by 100

0.3085 * 100 = 30.85%

The formula of a volume os a cylinder:

[tex]V=\pi r^2H[/tex]

r - radius

H - heihgt

The formula of a volume of a cone:

[tex]V=\dfrac{1}{3}\pi r^2H[/tex]

r - radius

H - height

If a cylinder and a cone have the same radius and height then the volume of a cone is three times smaller than a volume of a cylinder.

Therefore

[tex]V_{cone}=\dfrac{1}{3}V_{cylinder}[/tex]

We have

[tex]V_{cylinder}=72\ in^3[/tex]

Substitute:

y = 8 sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use sin and cos

sin 30 = opposite/ hypotenuse

sin 30 = y/ 16 sqrt(3)

Multiply each side by 16 sqrt(3)

16 sqrt(3) * sin 30 = y

16 sqrt(3) * 1/2 = y

8 sqrt(3) = y

cos 30 = adjacent/ hypotenuse

            = x/16 sqrt(3)

Multiply each side by 16 sqrt(3)

16 sqrt(3) cos 30 = x

16 sqrt(3) * (sqrt(3)/2) = x

8 * sqrt(3)*sqrt(3)

8 * 3 = x

24 =x

Answer:

-15

Step-by-step explanation:

Given is a polynomial in x

[tex]F (x)= x^4 + 12x^3 + 30x^2 - 12x + 70[/tex]

We have to find the remainder when the above polynomial is divided by x+5

Remainder theorem says that f(x) gives remainder R when divided by polynomial x-a means f(a) = R

Applying the above theorem we can say that value of the function when x =-5

= Remainder when f is divided by x+5

= F(-5)

Substitute the value of -5 in place of x

= (-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70

= 625-1500+750+60+70

= 5

Hence answer is 5

Answer:

[tex]f(-5)=[/tex] 5

Step-by-step explanation:

According to the polynomial remainder theorem, when a polynomial f(x) is divided by a linear polynomial (x - a), the remainder of that division will be equal to f(a).

Therefore, substituting the value of x as -5 in the given function to find its value:

[tex]f(x)[/tex] = [tex]x^4 + 12x^3 + 30x^2 - 12x + 70[/tex]

[tex]f(-5)[/tex] = [tex](-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70[/tex]

[tex]f(-5)[/tex] = [tex]625+(-1500)+750-(-60)+70[/tex]

[tex]f(-5)[/tex] = [tex]5[/tex]

Therefore, the value of the given function when x = -5 is 5.

Answer:

CL=9

Step-by-step explanation:

I'm sorry I can't explain it but the answer is 9.

The measure of CL is 9 m.

Given that, in ∆ABC, m∠C= 90° AL is an angle bisector m∠ABC = 30°, LB = 18 m.

We need to find the measure of CL.

The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.

Now, sin 30°=CL/BL

⇒ 1/2 = CL/18

⇒ CL=9 m

Therefore, the measure of CL is 9 m.

Answer:

The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.  

Step-by-step explanation:

The binomial probability formula is expressed as follows:

P (k success in n trials) = [tex]\left \{ {{n \atop k} \right.[/tex] [tex]p^{k}[/tex][tex]q^{n-k}[/tex]

n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.  

In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.  

Yes, the student's card drawing experiment can be considered a binomial experiment and therefore the binomial probability formula can be applied. This is because there are two possible outcomes for each trial (success or failure), the trials are independent, and the number of trials is fixed.

Yes, the probability of drawing his favorite suit can be found by using the binomial probability formula. This is because the scenario described satisfies the conditions necessary for a binomial experiment.

First, there are only two possible outcomes for each trial - success (drawing his favorite suit) and failure (not drawing his favorite suit). In a standard deck of 52 cards with 4 suits, there are 13 cards of each suit. Therefore, the probability of success, p, is 13 out of 52, or 0.25 and the probability of failure, q, is 1 - p, or 0.75.

Second, the student performs the experiment 30 times. This means there are a fixed number of independent trials (n = 30). This is independent because he returns the card to the deck and shuffles after each draw, so the outcome of one trial does not affect the outcomes of the other trials.

In a binomial experiment, the random variable X represents the number of successes in n independent trials. The mean, µ, can be calculated using the formula µ = np, and the standard deviation, σ, is given by the formula σ = √npq. Thus, you can use the binomial probability formula to calculate the probability of drawing his favorite suit a certain number of times out of the 30 trials.

Answer:

x = 6

Step-by-step explanation:

We have to isolate x.

Distribute.

-282 = -30 - 42x

Add 30 to both sides.

-252 = -42x

Divide both sides by -42.

6 = x

Answer:

y = -1/2 x + 6

Step-by-step explanation:

2x + 4y = 10

4y = -2x + 10

y = -1/2 x + 5/2

Parallel lines, slope is the same = -1/2

passes through the point (8, 2) so

y - 2 = -1/2(x - 8)

y - 2 = -1/2 x + 4

y = -1/2 x + 6

Answer:

y = -1/2x + 6

Step-by-step explanation:

We know that the slope intercept form of a line is [tex]y=mx+c[/tex].

Also, if two lines are parallel, they have the same slope. So re-writing the given equation 2x + 4y = 10 in the slope intercept form to find know its slope.

[tex]2x + 4y = 10\\\\4y=-2x+10\\\\y=\frac{-2}{4} +\frac{10}{4}\\ \\y=\frac{-1}{2} +\frac{10}{4}[/tex]

So the slope of the equation will be [tex]-\frac{1}{2}[/tex].

Finding the y-intercept (c):

[tex]y=mx+c\\\\2=-\frac{1}{2} (8)+c\\\\c=6[/tex]

Therefore, the equation of the line n slope intercept form that is parallel to 2x + 4y = 10 and passes through the point (8, 2) is y = -1/2x + 6.

Answer : The value of constant of variation is, 540

Step-by-step explanation :

As we know that,

[tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]

That means,

d = s × t

Here,

's' is constant of variation.

Given:

d = distance = 810 km

t = time = 1.5 hr

Now put the values in the above expression, we get:

d = s × t

810 km = s × 1.5 hr

Array means arrangement of numbers in terms of rows and columns.

The conjecture is not True.

So, the conjecture made by chloe that given any two numbers, the greater number can always be arranged into more arrays is not true.

For example ,

2→(2×1),(1×2)

3→(3×1),(1×3)

This pair has same number of arrays because both of them are prime.

2. (3,4)

Here, 4>3

3→ (3 × 1),(1×3)

4→(4×1),(1×4),(2×2)

The pair of numbers are Co-prime, one of them is not prime. So Composite number has more number of arrays.

4. (6,11)

6→(1×6),(6×1),(2×3),(3×2)

11→(1×11),(11×1)

The number 6 is smaller, but it has more number of arrays.

5. (6,8)

6→(1×6),(6×1),(2×3),(3×2)

9→(1×9),(9×1),(3×3)

Answer:

The correct option is D.

Step-by-step explanation:

In a linear function the rate of change is constant. It means either the function increase by a constant rate or function decrease by a constant rate.

In an exponential function the rate of change is not constant.

It is given that the population of bacteria increases by 30 every hour.

Since the population of bacteria increases by a constant rate therefore the population function is linear and it is defined as

[tex]P(t)=P_0+30t[/tex]

Where P₀ is initial population and t is time in hours.

Therefore correct option is D.

In the situation where a population of bacteria increases by a constant amount every hour, the growth pattern is linear, not exponential. Exponential growth in bacteria involves a doubling (or increase by a certain factor), not a fixed increase, and results in a J-shaped curve when plotted over time.

The situation presented in the question, where a population of bacteria increases by 30 every hour, represents a linear function. This is because the function increases by a constant amount. So, the answer is D. Linear, because the function increases by a constant amount. The given scenario differs from an example of exponential growth typically seen in bacteria. In exponential growth, the population of bacteria would double (or increase by a certain factor) each hour as opposed to increasing by a fixed amount. Exponential growth in bacteria occurs when there is an unlimited supply of nutrients, and the population size, when plotted over time, results in a J-shaped growth curve. Here, the rate of increase itself increases with time. In contrast, the linear growth described in the question indicates a steady rate of increase.

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the price of the coat be = $ 49.99

Let the price of one skirt be = $ 24.99

The sales tax percentage of Sandra's purchase = 7 %

So , the price of 3 skirts = 3 x price of one skirt

Substituting the values in the equation , we get

The price of 3 skirts = 3 x 24.99

The price of 3 skirts = $ 74.97

Now , the total price of the purchase of Sandra = price of the coat + price of 3 skirts

Substituting the values in the equation , we get

The total price of the purchase of Sandra = $ 49.99 + $ 74.97

The total price of the purchase of Sandra = $ 124.96

And , the sales tax amount of the purchase by Sandra A = sales tax percentage of Sandra's purchase x total price of the purchase of Sandra

The sales tax amount of the purchase by Sandra A = ( 7/100 ) x 124.96

The sales tax amount of the purchase by Sandra A = 0.07 x 124.96

The sales tax amount of the purchase by Sandra A = $ 8.7472

Therefore , the value of A is $ 8.75

Hence , the sales tax amount of the purchase by Sandra is  $ 8.75
