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

Which of the following is true?
A.100 x 1,000 = 107
B.10 x 1,000 = 105
C.0.01 x 103 = 100
D.0.001 x 105 = 100
Answers
Answer:
None of the options are true.
Step-by-step explanation:
We are given with the following parts;
A. 100 x 1,000 = 107
B. 10 x 1,000 = 105
C. 0.01 x 103 = 100
D. 0.001 x 105 = 100
The first statement that 100 x 1,000 = 107 is false because the multiplication of the numbers 100 and 1,000 gives the result of 100,000 but in question; it is written as 107, So, this is false.
The second statement that 10 x 1,000 = 105 is false because the multiplication of the numbers 10 and 1,000 gives the result of 10,000 but in question; it is written as 105, So, this is false.
The third statement that 0.01 x 103 = 100 is false because the multiplication of the numbers 0.01 and 103 gives the result of 1.03 but in question; it is written as 100, So, this is false.
The fourth statement that 0.001 x 105 = 100 is false because the multiplication of the numbers 0.001 and 105 gives the result of 0.105 but in question; it is written as 100, So, this is false.
Hence, all the statements are false.
At a restaurant, a survey was conducted to find which beverage the customers preferred. In the survey, every woman customer was asked which beverage was her favorite. Were the results of the survey valid
Answers
Answer: No, because the sample was not random.
Step-by-step explanation:
For the results to have been valid, the sample would have had to be random meaning that only some of the people were chosen to participate at random.
Instead, EVERY woman customer was asked which means they were not chosen at random as they should have been. Also, they only surveyed women when they should have taken a proper sample consisting of all customers.

is ABC similar to DEF? Why or why not?
Answers
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.
What is the triangle?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.

Jess borrows $250 from the bank. The bank charges 11% simple interest over 2 years. How much will Jess owe the bank at the end of 2 years? $27.50 $55.00 $277.50 $305.00
Answers
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]
Jess will owe the bank $305.00 at the end of the 2 years.
Find the measure of c. A. 40 B. 70 C. 90 D. 50
Answers
Answer:
D. 50
Step-by-step explanation:
a = 90° (angle subtended in semicircle)
a + c + 40° = 180° (by angle sum postulate of a triangle)
90° + c + 40° = 180°
c + 130° = 180°
c = 180° - 130°
c = 50°
The measure of angle c will be 50 degrees. so option D is correct.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
Consider an arc of a circle.
Suppose it subtends θ angle on the rest of the part of the circumference (at any point). Then it subtends 2θ angle on the center of that circle.
a = 90° (angle subtended in semicircle)
a + c + 40° = 180° (by angle sum postulate of a triangle)
90° + c + 40° = 180°
c + 130° = 180°
c = 180° - 130°
c = 50°
Therefore, the measure of angle c will be 50 degrees. so option D is correct.

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.

. Write the quadratic equation in factored form. Be sure to write the entire equation. x^2 - 5x - 24 = 0
Answers
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]

Is the sum of two monomials always a monomial? Is their product alwahs a monomial?
Answers
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.
