Answer:
It is 20 white marbles
step by step explanation:
Fraction of the yellow marbles:
[tex]1 - \frac{1}{4} - \frac{3}{8} = \frac{3}{8} [/tex]
let total number of marbles be x :
[tex]{ \sf{ \frac{3}{8} \: of \: x = 30 \: yellow \: marbles}} \\ \\ \frac{3}{8} \times x = 30 \\ \\ 3x = 30 \times 8 \\ 3x = 240 \\ x = 80[/tex]
Total marbles = 80 marbles
for white marbles:
[tex] = \frac{1}{4} \times 80 \\ \\ = 20[/tex]

Answer:
B. 2 x (6 + 9) = (2 x 6) + (2 x 9)
Step-by-step explanation:
The distributive property says the product is the sum of the products of the outside factor with each of the terms inside parentheses. In generic form:
a(b +c) = ab +ac
Here, we have a=2, b=6, c=9.
2(6 +9) = 2(6) +2(9)

Answer:
3 feet
Step-by-step explanation:
The equation with all the parameters filled in is ...
f(t) = -16t² +8t +2
The maximum height occurs at the vertex of the function, which can be written in vertex form as ...
f(t) = -16(t² -1/2t) +2
f(t) = -16(t² -1/2t +1/16) +2 +16(1/16)
f(t) = -16(x -1/4)² +3
The vertex of the graph is (1/4, 3), so the maximum height is 3 feet.

A. 18.3
OB 21.8
OC. 22.8
D. 28.2
<<
Answer:
A) 18.3
Step-by-step explanation:
Since adding b and a gives 19.
c must be less than 19.
So, A) 18.3 is the correct answer
We know that the sum of measure of any two sides of a triangle is greater than the third Angle.
So, in this case,
( a + b ) > cOr, 9 + 10 > cOr, 19 > cNow, here only 19 is only greater than 18.3 from the options. Hence, 18.3 is the correct answer.
Which products result in a difference of squares? Check all that apply.
PLEASE HELP ME
I NEED HELP!
Answer:
2nd - (w - 5)(w + 5)
4th - (-4v - 9)(-4v + 9)
Step-by-step explanation:
1. The first option shows an expression multiplied by its opposite(x -1), so therefore, it does not show the difference of squares
2. The second option does show the difference of squares because it is in the form (a + b)(a - b)
3. The third option is just a square because the same expression is multiplied by itself.
4. The fourth option is the difference of squares because it is in the form (a + b)(a - b). a equals -4v and b equals 9 in this case.
5. The fifth option is not the difference of squares. No term in common in both expressions
6. The sixth option is just a square because the same expression is multiplied by itself.
In all, there are two options that are the difference of squares, the 2nd and 4th.
Can someone do number 4 please. and show the work if you can
Step-by-step explanation:
[tex]\overline{CA} + \overline{AT} = \overline{CT}[/tex]
Since A is the midpoint, then [tex]\overline{CA} = \overline{AT}.[/tex] Therefore, we can write

Which of the following rational functions is graphed below?
Answer:
D
Step-by-step explanation:
The graph has vertical asymptotes x = 1 and x=2. It means that the denominator is approaching zero when x is close to 1 or x close to 2. Hence the denominator has factor x -1 and x-2 and D is the only option to have that.

Answer:
225
Step-by-step explanation:
The sides of the small square is 5 m
There are 5 full shaded squares and 8 half squares
Shaded squares = fully shaded small squares + half squares
S = F + H
F = 5x5x5 = 125
H = 8/2 x 5² = 100
S = 100 + 125
S = 225

[tex]\frac{1}{\sqrt{x} 5}[/tex]
Answer:
[tex] \frac{ \sqrt{5x} }{5x} [/tex]
Step-by-step explanation:
[tex] \frac{1}{ \sqrt{x5} } [/tex]
[tex] = \frac{1}{ \sqrt{5x} } [/tex]
[tex] = \frac{1}{ \sqrt{5x} } \times \frac{ \sqrt{5x} }{ \sqrt{5x} } [/tex]
[tex] = \frac{1 \sqrt{5x} }{ \sqrt{5x \sqrt{5x} } } [/tex]
[tex] = \frac{\sqrt{5x} }{ \sqrt{5x \sqrt{5x} } } [/tex]
[tex] = \frac{ \sqrt{5x} }{5x} [/tex]
In the 2007–2008 season,
Dwayne Wade made 439 field goals out
of 937 attempts. What was Dwayne
Wade’s ratio of successful field goals to
attempts? Write your answer as both a
fraction in simplest form and a decimal
rounded to the nearest thousandth.
Answer:
Step-by-step explanation:
Answer as a fraction = 439/937
Answer as a decimal = 0.469
===================================================
Explanation:
He made 439 baskets out of 937 attempts. So we simply form the fraction 439/937. The number of makes or successes is up top, while the number of attempts is at the bottom. The order is important.
Both 439 and 937 are prime numbers. This means the faction 439/937 cannot be reduced. So we leave it as is.
----------------
You can use a calculator or long division to find that
439/937 = 0.4685
which is approximate. Rounding to the nearest thousandth (i.e. 3 decimal places) will lead us to 0.469
If we were to move the decimal 2 spots to the right, then we convert to percent form and that's roughly 46.9%
Expression sum for 18 and 12 subtracted from 50
Answer:
50 - (18+12)
Step-by-step explanation:
First write the sum of 18 and 12 in parenthesis. (18+12)
Then you write 50 - in the beginning of the expression because the sum of (18+12) will be substracted "from" 50.
