213÷ 20= 10.65
to round it up they would hire 11 teachers for every 20 students with a total of 213 students.

Answer: yes

Step-by-step explanation:

Lets look at side AC and BC.

BC = 10

AC = 15

10/15 = 2/3

Now side CE and CD.

CD = 8

CE = 12

8/12 = 2/3

SO YES!

The table below represents a linear function f(x), and the equation represents a function g(x): X) -1, 0, 1 F(x) -5, -1, 3 G(x)=

fredd [130]

Answer:

(a) g(x) has a greater slope

(b) g(x) has a greater y intercept

Step-by-step explanation:

Given

$x \to -1,0,1$

$f(x) \to -5,-1,3$

$g(x) = 4x + 3$

Solving (a): Compare the slopes

Slope (m) is calculated as:

$m =\frac{y_2 - y_1}{x_2 - x_1}$

So, for f(x), we have:

$m =\frac{-1- 0}{-5- -1}$

$m =\frac{-1}{-4}$

$m =\frac{1}{4}$

For g(x), we have:

Assume $g(x) = mx + c$ then the slope is m

Compare the above to $g(x) = 4x + 3$

Then the slope of g(x) is 4

g(x) has a greater slope

Solving (b): Function with greater y intercept

Here we set $x= 0$

From the table of f(x)

$f(x) = -1$ when $x = 0$

From $g(x) = 4x + 3$

$g(0) = 4 * 0 + 3$

$g(0) = 3$

Hence:

g(x) has a greater y intercept

Solve <br> (b-2ya^2)(3b-3ya^2)

elena-14-01-66 [18.8K]

Here we are given the expression:

$(b-2ya^{2})(3b-3ya^{2})$

We will use foil method to solve this expression.

The word FOIL is an acronym for the four terms of the product:

First ("first" terms of each binomial are multiplied together)

Outer ("outside" terms are multiplied—that is, the first term of the first binomial and the second term of the second)

Inner ("inside" terms are multiplied—second term of the first binomial and first term of the second)

Last ("last" terms of each binomial are multiplied)

Using this method let us simplify our expression.

$(b-2ya^{2})(3b-3ya^{2})$

= $3b^{2}-3bya^{2}-6bya^{2}+6y^{2}a^{4}$

Now combining like terms we have:

= $3b^{2}-9bya^{2}+6y^{2}a^{4}$

Answer: $(b-2ya^{2})(3b-3ya^{2})$ simplifies to $3b^{2}-9bya^{2}+6y^{2}a^{4}$

choli [55]

Answer:

she would need 2 bags because it is 18 but covers 10 square feet

Step-by-step explanation:

Width = 1 yard = 3 feet

Length = 6 feet

Square feet(area) of the floor = 6ft × 3ft = 18sqft

1 bag = 10sqft

x bag = 18 sqft

x bags = (18 × 1)/10

= 1.8 bags

2 bags
