Answer:
7
Step-by-step explanation:
the fraction 49/7 is the same as the problem 49÷7
If you do the problem, you get 7, and if you want to check you could do the inverse- 7x7=49. Since that checks out, 7 is your answer.
Hope this helps :)

Order of operation in quadratic equations
Answer:
4x²√4√6√x⁶√x
Step-by-step explanation:
4x²√(24x⁷)
The above expression can be simplified as follow:
4x²√(24x⁷)
Recall
√(MN) = √M × √N = √M√N
Thus,
4x²√(24x⁷) = 4x²√24√x⁷
But:
√24 = √(4×6) = √4√6
√x⁷ = √x⁶√x
Thus,
4x²√24√x⁷ = 4x²√4√6√x⁶√x
Therefore,
4x²√(24x⁷) = 4x²√4√6√x⁶√x
When Melissa was born, her parents put $8,000 into a college fund account that earned 9% simple interest. Find the total amount in the account after 18 years. *
Answer:
$20,960
Step-by-step explanation:
Melissa's parent saved 8 000 dollars in the bank for her college fund account. It earns 9% annual interest. After 18 years, how much interest will it accumulate and how much is the total amount that Melissa will have fore her college fund.=> 9% = 9% / 100% = 0.09Let's find the annuak interest first => 8 000 dollars * .09 = 720 dollars The, let's find the after 18 years interest=> 720 dollars * 18 = 12 960 dollarsTotal of the amount: => 8 000 + 12 960 = 20 960 dollars
This is the same as the one above me but in simpler terms
Step-by-step explanation:
I =8000 x 9 x 18 =12,960
Total amount = 12960 +8000= $20,960
Answer:
$12960
Step-by-step explanation:
A=P(1+rt)
8000(1 + (0.09 × 18)) = 20960
A = $20,960.
I = A - P
I=20960-8000
ANS=$12960

GIVING OUT BRAINLIEST ANSWER !! HELP ME OUT PLSS!!
Answer:
x = 7 hope this helps !!!
Step-by-step explanation:
Type 1: You know the short leg (the side across from the 30-degree angle). Double its length to find the hypotenuse. You can multiply the short side by the square root of 3 to find the long leg.
Type 2: You know the hypotenuse. Divide the hypotenuse by 2 to find the short side. Multiply this answer by the square root of 3 to find the long leg.
Type 3: You know the long leg (the side across from the 60-degree angle). Divide this side by the square root of 3 to find the short side. Double that figure to find the hypotenuse.
this is a type 3 triangle, and you can find the length of y from it, it being 14, and x is half of y, being 7
Tan (30) = x/7[tex]\sqrt{3}[/tex]

Which is more, 215 inches or 6 yards?
Answer:
6 yards is more, 6 yards converted into inches is 216
Step-by-step explanation:
Answer:
6 yards
Step-by-step explanation:
1 inch = 0.0277778 yard
=> 215 inches = 5.97222 yards
- But 5.97222 < 6
Therefore, 6 yards are longer than 215 inches

triangle PQR is similar to triangle XYZ if PQ = n + 2, QR = n - 2 and XY=n^2 - 4, what is the value of YZ, in terms of n?
Answer:
(n-2)²
Step-by-step explanation:
If triangle PQR is similar to triangle XYZ, then;
PQ/QR =XY/YZ
Given
PQ = n + 2,
QR = n - 2 and
XY=n^2 - 4,
Substitute
n+2/n-2 = n²-4/YZ
n+2/n-2 = (n+2)(n-2)/YZ
1/n-2 = n-2/YZ
Cross multiply
YZ = (n-2)(n-2)
YZ = (n-2)²
Hence the value of YZ in terms of n is (n-2)²

Explain why we place this zero in the second line.
Step-by-step explanation:
we do this because when you start multiplying your 2nd digit you would put the zero to signifie that you started a mother digit.

If f(x)= - 4x-4, g(x)= 4x² + 4x + 2, and h(x)= 3x2 – 3, find f(3).
f(3) =
(Simplify your answer.)
Answer:
[tex]f(3) = -16[/tex]
Step-by-step explanation:
Given
[tex]f(x)= - 4x-4[/tex]
[tex]g(x)= 4x^2 + 4x + 2[/tex]
[tex]h(x)= 3x^2 - 3[/tex]
Required
[tex]f(3)[/tex]
We have:
[tex]f(x)= - 4x-4[/tex]
Substitute [tex]x = 3[/tex]
[tex]f(3) = -4 * 3 - 4[/tex]
[tex]f(3) = -12 - 4[/tex]
[tex]f(3) = -16[/tex]
Hence:
[tex]f(3) = -16[/tex]

5/21
5/20
Answer:
1/5
Step-by-step explanation:
7 + 13 =20
20 + 5 = 25
5 is a fifth of 25
Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
There are 25 socks in total, only 5 of these are green.

Answer:
x = 20
Step-by-step explanation:
The angles are supplementary so:

Step-by-step explanation:
Plug in 2 for x
(2)^3+6(2)^2+3(2)-5=
Answer:
B
Step-by-step explanation:
Remark
F(2) means that wherever you see an x on the right side of the equal sign, you substitute 2 for.
Suppose the question was f(2) = 3x + 5
Put a 2 where the x is.
f(2) = 3*2 + 5
f(2) = 6 + 5
f(2) = 11
Equation
f(x) = x3 + 6x2 + 3x -5.
Solution
f(2) = 2^3 + 6*2^2 + 3*2 - 5
f(2) = 8 + 6*4 + 6 - 5
f(2) = 8 + 24 + 1
f(2) = 33
Which of the following are mathematical sentences? Check all that applu
A. 4- d= 12
B. 4-V> 2
C. 3 + 2
D. 59
E. 6 + a = 13
F. 12x
Answer:
The correct options are:
A, B, and E.
Step-by-step explanation:
A mathematical sentence (or a mathematical statement) is a sentence that can be true or false.
This is the only criteria we need to check, now let's analyze each option.
A: 4 - d = 12
This can be true or false, for example, if d = 0 the sentence is false because:
4 - 0 = 12
4 = 12 is false.
and if d = -8 the sentence is true, because:
4 - (-8) = 12
4 + 8 = 12
12 = 12
is true.
B: 4 - V > 2
This sentence can be true or false, same reasoning as before, we can find values of V such that this is true or false.
C: 3 + 2
Now, here we can't say if this is true or false, so this is not a mathematical sentence.
D: 59
Same as before, this is just a number.
E: 6 + a = 13
This can be true or false, depending on the value of a, then this is a mathematical sentence.
F: 12*x
Here we can not say if this is true or false, so this is not a mathematical sentence.
The correct options are:
A, B, and E.
