2 answers:

7 0

1.How many terms are there? A term can be a signed number, a variable, or a constant multiplied by a variable or variables

There are 2

2.What is the constant term? Constants are the terms in the algebraic expression that contain only numbers.


Only 1

3.State the coefficient of the algebraic term.? Coefficient is a term that comes before the Variable term

Answer is the number 3 (you see before the letter x)

4.Write the operation symbol.

Answer is : + (the plus sign)

Answer: Delete the point (0, 4)

Step-by-step explanation:

Your line for y = (1/3)x + 4 is correct.

m=1/3 b=4

Start at (0, 4) and draw a line through a point up 1 and 3 to the right (3, 5).

Your line for x = 6 is correct.

A vertical line through (6, 0), (6, 1), (6, 2), ...

Your point for (6, 6) is correct.

x=6, y=6

Your error is that you used the dot tool to plot a point for (0, 4). You DO need this point to create the line y = (1/3)x + 4, however the instructions do not state to mark this coordinate with a dot.

The volume of a 10 ounce box of cheerios is 258.75in3. the length of the box is 4 inches less than the height and the width is 3

Marina86 [1]

Answer:

Height of the box = 11.5 in

Step-by-step explanation:

Let h be the height of the box.

Assuming the volume of the Box is $258.75\ in^3$ .

Given:

Length = Height - 4 = h - 4

Width = 3 in

We need to find the height of the box.

Solution:

We know that the volume of the box.

$Volume = Length\times height\times width$

Substitute all given value in above formula.

$258.75 = (h-4)\times h\times 3$

Rewrite the equation as:

$258.75 = 3h(h-4)$

$258.75 = 3h^2-12h$

$3h^2-12h-258.75=0$

whole equation divided by 3.

$h^2-4h-86.25=0$

Use quadratic formula with $a = 1, b = -4,c=-86.25$

$h=\frac{-b\pm \sqrt{(b)^{2}-4ac}}{2a}$

Put these a, b and c value in above equation.

$h=\frac{-(-4)\pm \sqrt{(-4)^{2}-4(1)(-86.25)}}{2(1)}$

$h=\frac{4\pm \sqrt{16+345}}{2}$

$h=\frac{4\pm \sqrt{361}}{2}$

$h=\frac{4\pm 19}{2}$

For positive sign

$h=\frac{23}{2}$

h = 11.5 in

For negative sign

$h=\frac{-15}{2}$

h = -7.5

We take positive value of h.

Therefore, the height of the box h = 11.5 in

Which ratio is higher 15:20 or 12:16. for 35 points

Margarita [4]

To find which ratio is higher, we can first convert the ratios into fractions (that makes it easier, at least for me) and then simplify the fractions and see which one is greater.

Since ratios are basically division, 15:20 = $\frac{15}{20}$ , and

12:16 = $\frac{12}{16}$

Now we simplify these fractions. 15 and 20 have a GCF of 5, so taking out the common number gives us the simplified fraction of $\frac{3}{4}$ .

12 and 16 have a GCF of 4, so taking out the common number gives us the simplified fraction of $\frac{3}{4}$ . Since $\frac{3}{4}$ = $\frac{3}{4}$ , these ratios are the same.
