Answer:

4.79

Step-by-step explanation:

4.79 is reasonable for the problem

The price of one paint set before the sale is $4.79

We are expected to determine the price of one paint set before the sale.

From the information given:

∴

The amount at which Yuri bought 1 paint set is:

[tex]\mathbf{= \dfrac{\$6.88}{2.0}}[/tex]

= $3.44

Recall that during the sale, the store reduce the price of each paint set by $1.35

Therefore, the price of one paint set before the sale is = $3.44 + $1.35 = $4.79

Answer:

It is A ( read below )

Step-by-step explanation:

There are two VERY similar looking ap3x questions, this one is A but if you look closely on the rightside triangle the angle may say 24 not 25. This is why!

The corresponding angles of the triangles ΔABC and ΔDEF will be the same. Thus, the correct option is A.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The corresponding angles of the triangles ΔABC and ΔDEF will be the same.

And the ratio is calculated as,

6/8 = 7.5/10

3/4 = 3/4

Thus, the correct option is A.

Answer: Hi!

First, we should find the square root of 68, which is 8.25. (an easy way to find the square root for numbers like this is to just use the calculator, as we can't automatically tell what it is; 68 isn't a perfect square number.) Since we know know the square root we can easily evaluate the questions!

Our answer is c), since the points only span from 0 - 8 and the square root of 68 is 8.25. Since 8.25 is greater than 8, it would be outside of the points and to the right of point Q.

Hope this helps!

Answer:

2.375

Step-by-step explanation:

Assuming you mean [tex]2\frac{3}{8}[/tex]  (if you meant [tex]\frac{23}{8}[/tex] ignore this answer):

The first part is just 2. That's pretty easy. 2 wholes is 2.0

The 2nd part is 3 eights. Let's figure out how much 1 eight is.

We know it's half of 1/4, which is 0.25

So 1/8 is 0.125

3/8 is thus 3 of those, or 3 * 0.125 = 0.375

Now let's add both parts together.

2 + 0.375 = 2.375

Answer: 2.375

Answer:

550 to 5.5

Step-by-step explanation:

Answer:

$305.00

Step-by-step explanation:

Use the formula I = prt, where I is the interest money created, p is the starting amount of money, r is the interest rate as a decimal, and t is time.

I = prt

I = 250(0.11)(2)

I = 55

Add 55 to the amount he borrowed:

250 + 55

= $305.00

Answer:

[tex]\huge \boxed{\mathrm{\$ \ 305.00}}[/tex]

Step-by-step explanation:

We can use the simple interest formula to calculate for the interest.

[tex]I=P \cdot r \cdot t \\ \\ \\ \sf I = interest \\ \\ P=principal \ amount \\ \\ r=rate \ (\%) \\ \\ t=time \ (years)[/tex]

Calculating the interest over the two years:

[tex]I=250 \cdot 11\% \cdot 2 \\\\ I=250 \cdot 0.11 \cdot 2 \\\\ I=55[/tex]

Adding the interest to the principal amount:

[tex]\Rightarrow 250+55 \\ \\ \Rightarrow 305[/tex]

Answer:

B

Step-by-step explanation:

Given

(4x + 3)(3x - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

4x(3x - 4) + 3(3x - 4) ← distribute both parenthesis

= 12x² - 16x + 9x - 12 ← collect like terms

= 12x² - 7x - 12

The coefficient of the x- term is - 7 → B

This may be the answer.

Answer:

[tex](x+3)(x-8)=0[/tex]

Step-by-step explanation:

First, write out the equation as it is given in the problem:

[tex]x^{2}-5x-24=0[/tex]

Now, you have to split up the "-5x" to get to factored form.  The way to do this is to look for the factors of "a" times "c" that sum to "b":

So, in this problem, a=1, b=-5, and c=-24.  So, find the factors of (1*-24) that sum to (-5). To clarify, (1*-24)=-24, so you have to find factorsof -24 that sum to -5.

Let's write out a list of factors.

[tex]1,-24---1+-24=-23no\\-1,24---1+24=23no\\2,-12---2+-12=-10no\\-2,12----2+12=10no\\3,-8---3+-8=-5yes[/tex]

Therefore, our two factors will be 3x and -8x.

Now, let's rewrite our equation with these new factors in place of the -5x:

[tex]x^{2}-5x-24=0\\x^{2}+3x-8x-24=0[/tex]

Next, find your factored expressions:

[tex]x^{2}+3x-8x-24=0\\(x^{2}+3x)(-8x-24)=0\\[/tex]

Take the GCF from each set of parenthesis:

[tex]x(x+3)-8(x+3)=0[/tex]

The GCFs that you took out will become your second in the set for factorde form.  It will be written as "x-8".

Therefore, your equation in factored form will be:

[tex](x+3)(x-8)=0[/tex]

Answer:

9.6

Step-by-step explanation:

Plugging in the info given, we get:

2(4) - (2/5)(-4) = 8 - (-8/5) = 8 + 8/5

From here, you need to make the denominators of both numbers the same in order to combine them further. Currently, as a fraction, it looks like this:

8/1 + 8/5

To make the denominators the same we can just multiply 8/1 by 5/5 (this is the same as multiplying by 1, which essentially allows us to change it's form without changing its value). Doing that gives:

(8/1)(5/5) + 8/5 = (8•5)/5 + 8/5 = 40/5 + 8/5

= (40+8)/5 = 48/5

So 48/5 is the answer. But the website wants you to put it into decimal form. This can be done using a calculator, but let's pretend we don't have one...

Decimals work by using whole numbers divided by multiples of 10 and can be visualized as moving a decimal left (or right) between numbers. For example:

1/10 = 0.1

4/10 = 0.4

23/10 = 2.3

13/100 = 0.13

59/1000 = 0.059 and so on.

So if we can multiply 48/5 by something to make the denominator some multiple of 10, we can simply move the decimal left once and that's our answer. 2/2 should work here:

(48/5)(2/2) = (48•2)/(5•2) = 96/10 or 96.0/10

96.0/10 = 9.6

So your decimal answer is 9.6.

Answer to the first question: no, the sum is not always a monomial

Consider adding 2x and 5y. Both of which are monomials. Their sum is 2x+5y. We don't have like terms, so we can't combine them. The sum is a binomial as it has 2 terms.

======================================

Answer to the second question: yes, their product is alway a monomial

Going back to 2x and 5y. Multiply those two monomials and we get 10xy as a product. This is a monomial as it is one term. If p and q are monomials, then so is pq.

Hello!

Answer:

[tex]\huge\boxed{x = -32}[/tex]

3/4x = -24

To isolate the "x" variable, divide both sides by 3/4 (multiply by its reciprocal, or 4/3)

3/4x · 4/3 = -24 · 4/3

x = (-24 · 4) / 3

x = -32.

Answer:

x = -32

Step-by-step explanation:

To solve an equation with a fraction, we multiply by the denominator on both sides of the equation and then solve like a normal algebraic equation.

3/4x = -24 Multiply by 4 on both sides of the equation.

4(3/4)x = -4(24) Distribute.

3x = -96 Divide by 3 on both sides of the equation.

x = -32

Answer:

C

Step-by-step explanation:

trust me

One plane can be drawn so it contains all three points. Then the correct option is C.

Non-collinear points are multiple or more points that cannot all lie on a single straight line. The points are considered non-collinear if any one of them is not situated on the same line as the other ones.

Let n be the number of non-collinear points. Then the number of lines that can be made will be

Number of lines = ⁿC₂

And the number of planes that can be made will be

Number of planes = ⁿC₃

If there are 3 non-collinear points, then the number of lines will be

Number of lines = ³C₂

Number of lines = 3

Then the number of planes will be

Number of plane = ³C₃ = 1

One plane can be drawn so it contains all three points. Then the correct option is C.
