d = 2*r

d = 2*7

d =14 m

Answer:

diameter = 14

given that the radius of a circle = 7m

diameter = ?

recall that the formulae for finding the diamer = 2 x radius

diameter = 2 x 7

diameter = 14

Answer:

6 7/8

Step-by-step explanation:

Since 1 cup of rice is added to 2 3/4 water

We are to determine the Amount of water to be to 2 1/2 cups of rice

Let the unknown number for water be x

So let's solve

1 cup of rice=11/4 water

5/2 cup of rice=x water

Cross multiply

x=5/2×11/4

x=55/8

X=6 7/8

Therefore,6 7/8 water is needed

Given:

θ = 54°

Radius = 10 in

To find:

The arc length of PQ

Solution:

Arc length formula:

[tex]$\text{Arc length}=2 \pi r\left(\frac{\theta}{360^\circ}\right)[/tex]

[tex]$\text{Arc length}=2 \times 3.14 \times 10\left(\frac{54^\circ}{360^\circ}\right)[/tex]

                 = 9.42 in

The arc length of PQ is 9.42 inches.

Answer:

The length of the sides is 8[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Since the diagonal divide a square into 2 45-45-90 triangles:

The diagonal is the hypotenuse of the triangle

Divide 16 by [tex]\sqrt{2}[/tex] and you will get 8[tex]\sqrt{2}[/tex].

Step-by-step explanation:

You will need to use the compound interest formula for this.

[tex]P(1+\frac{r}{n} )^{nt}[/tex]

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

Your equation will look like this:

Answer:

{1, 3, 5, 7, 9, 11}

The sample space of the odd number will be (1, 3, 5, 7, 9, 11).

Sample space simply means the possible outcomes that we can get when we make an experiment.

Odd numbers cannot be divided by 2. Examples include 1, 9, 11, 23, 45, 75 etc. In this case, the odd numbers that we can get from 1 to 11 will be 1, 3, 5, 7, 9 and 11 and this will be the sample space.

In conclusion, the sample space will be (1, 3, 5, 7, 9, 11)

Step-by-step explanation:

M is the mid point of AB

here given A ( - 7 , -7) and M ( -6 , -1) Let the coordinates of point B be ( x1, y1)

Now

( - 6 , -1 ) = {( x1 - 7)/ 2 , ( y1 - 7) / 2}

Equating

-6 = x1 -7 -1 = y1 - 7

2. 2

-12 = x1 - 7. -2 = y1 - 7

x1 = -12 +7. y1 = -2 +7

Therefore x1 = - 5. Therefore y1 = 5

Therefore the coordinates of B is ( -5 , 5)

Step-by-step explanation:

correct on edge

We can see that b1 = 18, b2 = 24, and h = 5

So, we can just substitute these in.

A = 1/2(18 + 24)5

A = 1/2 * 42 * 5

Answer:

J

Step-by-step explanation:

As you can see, the peak occurs at (2,6). That means that all values below 6 are in the range.

The division problems 123.4/9.2 and 71.9/6.5 have an estimated quotient of 12 by considering 123.4 as 120, 9.2 as 10, 71.9 as 70, and 6.5 as 6.

The division problems with an estimated quotient of around 12 will be the ones where you divide a number close to 120 by 10. In this case, it comes to be 123.4/9.2 and 71.9/6.5. To estimate the quotient, you can consider 123.4 as approximately 120 and 9.2 as approximately 10. Similarly, 71.9 can be considered as approximately 70 and 6.5 as approximately 6. When you divide these estimate numbers, both quotients are close to 12.

Estimation is a useful skill in Mathematics that allows you to simplify complex problems and get close to the exact answer. It's particularly helpful in situations where you only need a rough estimate and not the exact figure.

The fourth listed answer:

Domain: All Real numbers

Range : { f{x) | f(x) [tex]\leq[/tex] 0, f(x) = 1 }

Step-by-step explanation:

The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.

The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value  "x" of the domain. The line with positive slope extends to all f(x) values that are [tex]\leq[/tex] 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.

[tex]y=-150x+1600[/tex]

Step-by-step explanation:

Linear Equation:

[tex]$y=mx+b$[/tex]

[tex]f(x)=mx+b[/tex]

Consider:

The pool is full when the time is zero:

[tex]1600=m(0)+1600[/tex]

It is emptied (-) in the rate 150 gallons every hour.

[tex]f(x)=-150x+b[/tex]

[tex]f(x)=-150x+1600[/tex]

[tex]y=-150x+1600[/tex]

The slope-intercept form of the equation 4x + 3y = -3 is y = -4/3x - 1. The slope of the line is -4/3 and the y-intercept is -1.

The question asks to convert the equation 4x + 3y = -3 into slope-intercept form, and simplify all fractions. The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept.

To transform the given equation into this form, we need to express it in terms of y. Here are the steps:

In this equation, the term -4/3 is the slope and the -1 is the y-intercept. That means the line decreases for every 4 units in the y-axis when it increases 3 units in the x-axis.

Answer:

Step-by-step explanation:

Point D (3,1); Point B (-1,-2); Point C (4, -2)

Point D lies on the circle whose center is Point B and which contains the Point C if the distance:

BD = BC

BD^2 = BC^2

(- 1 - 3)^2 + (- 2 - 1)^2 = (4 - (-1))^2 + (-2 - (-2))^2

16 + 9 = 25

25 = 25

Follows, point D lies on the circle with radii 5.

To solve graphically we first need to write the equation of the circle whose center is Point B and which contains the Point C:

(x - (-1))^2 + (y - (-2))^2 = 5^2

(x + 1)^2 + (y + 2)^2 = 5^2

m = the number of miles driven

Company A cost = 76    

[they charge $76 for unlimited mileage, so they don't charge by the miles driven]

Company B cost =  0.70m + 55  

[they charge an initial fee of $55 plus $0.70 per mile(m)]

For what mileages will Company A charge less than Company B?

Company A cost < Company B cost  ----->   76 < 0.70m + 55      

To solve for m, isolate/get the variable "m" by itself in the inequality:

76 < 0.70m + 55     Subtract 55 on both sides

76 - 55 < 0.70m + 55 - 55

21 < 0.70m     Divide 0.70 on both sides to get "m" by itself

[tex]\frac{21}{0.70} <\frac{0.70m}{0.70}[/tex]

30 < m      [m is any number greater than 30]

Company A will charge less than Company B for mileages over/greater than 30.

Final answer:

Company A will charge less than Company B when more than 30 miles are driven; the inequality used to determine this is 76 < 55 + 0.70m, and after solving, it shows that m > 30.

Explanation:

To find out for what mileages Company A will charge less than Company B, we need to set up an inequality based on the given price structures for both companies:

Company A charges a flat rate of $76 per day, regardless of mileage.

Company B charges an initial fee of $55 plus $0.70 per mile driven.

The inequality to represent this scenario is:

76 < 55 + 0.70m

To solve for m (the number of miles driven), we subtract 55 from both sides:

21 < 0.70m

Then, divide both sides by 0.70 to isolate m:

m > 30

So, Company A will charge less than Company B when Bob drives more than 30 miles.
