if x squared by 3 equal 64 what is the value of x

Answer:

6 batches

Step-by-step explanation:

1/3*6=2 cups of paint.

so they can make 6 batches and have 1 cup of yellow paint left

Answer:

a. No

b. Yes

c. No

Step-by-step explanation:

a. For BC and B'C to both be parallel to the y-axis when BC is parallel to the y-axis the figure must be rotated by a multiple of 180 degrees.

b. When you rotate a figure none of the angles in the figure change.

c. For D and D' to have the same coordinates the figure must be rotated by 360.

Answer:

2(x + y)

Step-by-step explanation:

You can pull out a 2 from the expression.

So divide 2x by 2 and 2y by 2.

2x/2 = x

2y/2 = y

2(x + y)

=1/6

Answer:

0.1666666666

I'd say 1.16

Answer:

Function A has the greater initial value because the initial value for Function A is 6 and the initial value for Function B is 3.

Step-by-step explanation:

✔️Function A:

Initial value = y-intercept (b)

y-intercept is the value of y, when the corresponding value of x = 0

From the table, y = 6 when x = 0.

The y-intercept of function A = 6

Therefore, initial value for Function A = 6

✔️Function B:

y = 4x + 3 is given in the slope-intercept form, y = mx + b.

b = y-intercept = initial value.

Therefore

Initial value for Function B = 3

✔️Function A has the greater initial value because the initial value for Function A is 6 and the initial value for Function B is 3.

This is your answer

Answer:

(20×20)+(2×20×30)

400+1200

1600inches^2

Answer:

1600 in^2

Step-by-step explanation:

We only have to add the areas of one square in the centre and 4 surrounding triangles.

area of the square=20×20=400 in^2

area of one triangle=1/2×20×30=300 in^2

area of four triangles=4×300=1200 in^2

So, total surface area of the square pyramid=400+1200=1600 in^2

*The units given should be in^2.

Answer:

$31.50

Step-by-step explanation:

First find 5 percent of 30 which is 5 divided by 100 multiplied by 30 then add the answer to 30 to get the answer to the question

Answer:

lateral surface area of a pyramid= 1/2pl or pl/2

Answer:

(5x)(3x)

Step-by-step explanation:

you would multiply (5x)(3x) first

and your final answer would be 15x ^ 2 - 13x - 6

Answer:

The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

T interval

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 10 - 1 = 9

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.833

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.833\frac{49}{\sqrt{10}} = 28.4[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 528 - 28.4 = 499.6 mg

The upper end of the interval is the sample mean added to M. So it is 528 + 28.4 = 556.4 mg

The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).

Answer:

63.59 (c)

Step-by-step explanation:

Formula: π[tex]r^{2}[/tex]

Plug in data:

9cm is diameter and a radius is half a diameter so the radius is 4.5cm.

π x 4.5^2 = 63.59cm^2

Answer: 6

Step-by-step explanation:

360 divided by 60 =6

Step-by-step explanation:

we know that slope of the line is

[tex] - \frac{4}{3} [/tex]

if the line is perpendicular to the other line, the product

of the slope is -1

so the answer is -4x+3y=-24 or

4x-3y=-24

you also can change the 24 to others number because it will not influences the slope.

Answer:

289

Step-by-step explanation:

1. if to re-write the given equation, then 13y²-9y-4=0;

2. if to calculate the required discriminant, then:

D=81+13*4*4=208+81=289.

Answer:

289

Step-by-step explanation:

[tex]13y^2-9y-4 = 0\\[/tex]

D = [tex]b^2-4ac[/tex]

Wherein,

b = 9

a = 13

c = -4

[tex]D = 9^2-(4*13*-4)\\= 289[/tex]

Answer:

y = 7x + 12

Step-by-step explanation:

Slope (m) = 7

Line is passing through the point (0, 12)

y-intercept (b) = 12

Equation of line in slope-intercept form is given as:

[tex]y = mx + b \\ \\ y = 7x + 12[/tex]
