Answer:

3/4 into decimal = 0.75

0.75 X 100 = 75

2 X 100 = 200

200/75 = 2.66666666

Answer:

We conclude that 14% of last semester's college cost was spent on books.

Step-by-step explanation:

The cost spent at community college = $2200

The amount spent on books = $308

The % of last semesters college costs was spent on books can be determined using the formula

% spent books on = [308 / 2200] × 100

                               = 0.14 × 100

                                = 14%

Therefore, we conclude that 14% of last semester's college cost was spent on books.

Volume of the cone, V=1/3*Π*r^2*h

we have the slant height, and we need to find the h, height

a^+b^2=c^2

where c is 13

169=25+h^2

h^2=144

h=12

V=1/3*3.14*25*12=100*3.14=314.15 ft^3

Answer:

1,600 dollars

Step-by-step explanation:

The easiest way to solve it is to find the dollar for 1 percent.

Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.

Answer:

[tex](4^{-2})^5=\dfrac{1}{4^{10}}[/tex]

Step-by-step explanation:

The given expression is : [tex](4^{-2})^5[/tex]

We need to simplify the above expression.

We know that, [tex]x^{-a}=\dfrac{1}{x^a}[/tex]

or

[tex](4^{-2})^5=(\dfrac{1}{4^2})^5\\\\=\dfrac{1^5}{(4^2)^5}\\\\\because (x^b)^c=x^{b\times c}\\\\=\dfrac{1}{4^{10}}[/tex]

So, the simplified form of the given expression is [tex]\dfrac{1}{4^{10}}[/tex]. Hence, the correct option is (A).

proportion: 1.93/23 = y/x

solve for y: y = x(0.083913)

Step-by-step explanation:

The required relationship of the proportionality is y = 0.08 x.

Given that,
In 23 minutes, Halona travels 1.93 kilometers to a neighbor's home. assuming she moves at a steady pace.
How many kilometers, y, Halona can walk in x minutes, expressed as a proportion. After that, find y using your percentage.

The relationship between two or more sets of values—whether they are directly proportional or inversely proportional to one another—is referred to as proportionality.

Here,
according to the question,
y ∝ x
y = kx
Where k is the constant of the proportionality,
at x = 23, y = 1.93
1.93 = 23 k
k = 1.93/23
k = 0.08
Put k in the proportionality equation,
y = 0.08k

Thus, the required relationship of the proportionality is y = 0.08 x.

Answer:

The values of p and q such that 2·x² - 4·x + 3 = 2·(x - p)² + q, are;

p = 1, q = 1

Step-by-step explanation:

The given equation are;

2·x² - 4·x + 3 = 2·(x - p)² + q

By expanding the right hand side of the equation, we have;

2·x² - 4·x + 3 = 2·(x - p)² + q = 2·x² - 4·p·x + 2·p² + q

2·x² - 4·x + 3  = 2·x² - 4·p·x + 2·p² + q

Comparing the coefficient of x in both equations, gives;

2·x² + (- 4)·x + 3  = 2·x² + (- 4·p)·x + 2·p² + q

-4 = -4·p

∴ p = -4/(-4) = 1

p = 1

Comparing only the constant terms (terms not multiplied by "x" or "x²"), we get;

3 = 2·p² + q

Substituting the value for "p" obtained above (p = 1 ) in the previous equation, we get;

3 = 2 × 1² + q  = 2 + q

∴ q = 3 - 2 = 1

q = 1.

Answer: y = -2x + 5

Step-by-step explanation:

y = -2x + 5

slope = -2

Slope intercept form of equation of line is given by y = mx + c

where m is the slope of line

c is the y intercept i.e point where given line intersect y axis.

________________________________________________

given equation 4x + 2y = 10

we have to re-write this equation in form y = mx + c

4x + 2y = 10

subtraction 4x from LHS and RHS

4x + 2y - 4x= 10 - 4x

2y = 10- 4x

we have to eliminate 2 from y for that we

divide  LHS and RHS by 2 we

2y /2 = 10/2- 4x/2

y = 5 - 2x

rearranging it in y = mx+c form

y = -2x + 5

thus, m = -2 , c = 5

Answer:

y=-2x+5, slope= -2, y-intercept= 5 (so, first option)

Step-by-step explanation:

y=mx+b. m is the slope, and b is the y-intercept. to get the equation to the slope intercept form, you get y by itself- subtract 4x from both sides and then divide by 2 on both sides.

Answer:

[tex]x=16 \ \ and \ \ y=4[/tex]

Step-by-step explanation:

Suppose the numbers are x and y

One number say x is equal to 4 times another number say y

[tex]x=4y[/tex]  ---------------- (1)

Their difference is 12

[tex]x-y=12[/tex]  ------------(2)

Put x=4y in equation (2)

[tex]4y-y=12[/tex]

[tex]3y=12\\y=4[/tex]

Put y=4 in equation (1)

[tex]x=4(4)\\x=16[/tex]

Answer:

x=2

Step-by-step explanation:

First you put the equations in the form of y = mx + b

Then once they are like that it would look like:

y = -2x + 6

y = 3x - 4

So then you can set them equal to each other and it will look like this:

-2x + 6 = 3x - 4

Then you add 2x to both sides and get:

6 = 5x - 4

Next, add 4 to both sides and get:

10 = 5x

So then you will simplify by dividing both sides by 5 and getting:

2 = x

Answer:

the price of the t-shirt is inversely proportional to the number of t-shirts to be bought.

Step-by-step explanation:

The total amount to be spent on t-shirts is $800.

The function;

   n(p) = 800 / p (price in dollars)

as the price per shirt increases, the number of shirt decreases and the curve moves down towards zero. When the price per shirt decreases, the number of shirt increases moving the curve upwards to infinity

Evaluate 9 to the power of -1/2

=> 0.05

The equivalent expression of ''9 to the power of -1/2'' would be 1/3.

Used the concept of the square root of a number that states that,

Brother = 3 * as much as your friend

Required

Write an expression for the cost of your brother's drone

I'll solve by analysing the question one sentence after the other

You:

[tex]Drone = d[/tex]

Your friend:

Friend = $35 more expensive than yours.

This means

[tex]Friend = 35 + You[/tex]

Substitute d for You

[tex]Friend = 35 + d[/tex]

Your brother:

Brother = 3 * as much as your friend

This means:

[tex]Brother = 3 * Friend[/tex]

Substitute 35 + d for Friend

[tex]Brother = 3 * (35 + d)[/tex]
