[tex]\displaystyle\ 60^2 =36(36+x)\\\\1296+36x=3600\\\\36x=2304\\\\\boxed{x=64}[/tex]
Step By Step Explanation:
[tex] {60}^{2} = 36(36 + x)[/tex]Step 1Calculate 60 to the power of 2 and get 3600.
[tex]3600 = 36(36 + x)[/tex]Step 2Use the distributive property to multiply 36 by 36 + ×.
[tex]3600 = 1296 + 36 \times [/tex]Step 3Swap sides so the all variable terms are on the left hand side.
[tex]1296 + 36 \times = 3600[/tex]Step 4Subtract 1296 from both sides.
[tex]36 \times = 3600 - 1296[/tex]Step 5Subtract 1296 from 3600 to get 2304.
[tex]36 x = 2304[/tex]Step 6Divide both side by 36.
[tex] \times = \frac{2304}{36} [/tex]Step 7Divide 2304 by 36 to get 64
My Answer is
[tex]\color{GREEN} \times = 64[/tex]HELPPP
A. X=20, y=10
B. X=15, y=8
C. X=20, y=12
D. X=15, y=12
Answer:
Step-by-step explanation:
If this is a parallelogram, then opposite sides are congruent and opposite angles are congruent. That means that
2y + 8 = 3y - 4 and
3x + 25 = 5x - 5
We'll solve that first equation for y:
-y = -12 so
y = 12 Now onto x:
-2x = -30 so
x = 15
Choice d is the one you want.
a right triangle is 18 inches long and a hypotenuse that is 30 inches long. what is the perimeter, in inches, of this triangle?
Answer:
The perimeter is 72 inches
Step-by-step explanation:
using the pythagorean theorem we can solve for the missing leg by plugging in the values we know.
[tex]a^{2} + b^{2} = c^{2} \\18^{2} + b^{2} = 30^{2} \\324 + b^{2} = 900\\ b^{2} = 900-324\\b^{2} = \sqrt{576} \\b= 24[/tex]
now you just add the values, 30 + 24 + 18
Clara lends half her collection of formal attires to her sister, Susan. Clara then buys four more attires. If she has 12 attires now, how many attires did Clara initially?
Answer:
16
Step-by-step explanation:
Number of attires Clara has initially = x
lends half her collection of formal attires to her sister
Attires remaining after lending = Number of attires Clara has initially - attires she lent her sister
= x - 1/2x
= 1/2x
Clara then buys four more attires
= 1/2x + 4
If she has 12 attires now
12 = 1/2x + 4
12 - 4 = 1/2x
8 = 1/2x
x = 8 ÷ 1/2
= 8 × 2/1
= 16
x = 16
Number of attires Clara has initially = x = 16

Simplify: a. 18 - 7 + 9* 48/6 - 5 (1) b. 72/ 12 [ 180/4{10 +(15 - 45 /9*2)}]
Answer:
[tex]a)\ 5.06 * 10\³[/tex]
[tex]b)\ 6.079 * 10^6[/tex]
[tex]c)\ 3\ crore = 30\ million[/tex]
[tex]d)\ 999999[/tex]
[tex]e)\ 10478[/tex]
[tex]f)\ 78[/tex]
[tex]g)\ 2730[/tex]
Step-by-step explanation:
Solving (a): 5060 as a power of 10
We simply move the decimal between 5 and 6. The number of zeros to move backward is 4.
So,
[tex]5 0 6 0 = 5.06 * 10^3[/tex]
Solving (b): 6079000 as a power of 10
We simply move the decimal between 6 and 0. The number of zeros to move backward is 4.
So,
[tex]6079000 = 6.079 * 10^6[/tex]
Solving (c): 3 crore to millions
[tex]1\ crore = 10\ million[/tex]
Multiply by 3
[tex]3\ crore = 30\ million[/tex]
Solving (d): The greatest 6 digits
The greatest unit digit is 9. So, we simply write out 9 in 6 places
[tex]Greatest= 99999[/tex]
Solving (e): The least 5-digit formed from 4,1,8,0,7
To do this, we start the number from the smallest non-zero digit.
The remaining 4 digits will then be in an increasing order
So, we have:
[tex]Least = 10478[/tex]
Solving (f):
[tex]18 - 7 + 9 * \frac{48}{6} - 5[/tex]
Using BODMAS
Evaluate the division, first
[tex]18 - 7 + 9 * 8 - 5[/tex]
Then multiplication
[tex]18 - 7 + 72 - 5[/tex]
Add up the remaining digits
[tex]78[/tex]
Solving (g): This question is not clear.
I will assume the expression is:
[tex]\frac{72}{ 12}* [ \frac{180}{4}*{10 +(15 - \frac{45}{9}*2)}][/tex]
Evaluate all divisions
[tex]6* [ 45*{10 +(15 - 5*2)}][/tex]
Solve the multiplication in brackets
[tex]6* [ 45*{10 +(15 - 10)}][/tex]
Remove the inner bracket
[tex]6* [ 45*{10 +5}][/tex]
Evaluate 45 * 10
[tex]6* [ 450 +5}][/tex]
Remove the bracket
[tex]6* 455[/tex]

A loan of 28,000 is made at 4% interest, compounded annually. After how many years will the amount due reach 48000 or more?
Answer:
The time is 13.7 years.
Step-by-step explanation:
principal, P = 28000
Rate of interest , R = 4 % annually
Amount, A = 48000
Let the time is t.
Use the formula of the compound interest.
[tex]A = P\times \left ( 1+\frac{r}{100} \right )^t\\\\48000 = 28000\times \left ( 1+\frac{4}{100} \right )^t\\\\1.71 = 1.04^t\\\\log 1.71 = t log 1.04\\\\t =\frac{0.233}{0.017}\\\\t = 13.7 years[/tex]
Simplify the radical (180°.
Answer:
radical is sqrt we find 180 sqrt root
Step-by-step explanation:
first we write sqrt 180
sqrt 180 = ?
we can choose first two letters
18 are two letters
4^2 + 2 = 18
so first + third number choose
4 , 2 are number choose
4 + 2 sqrt (4+2-1)
6 sqrt 5
sqrt 180 = 6sqrt 5
what are the lengths of SV and QT? no links.
ok so we see that TR is 17 units, so RV is the same amount
3x+2 so 3x=15 so divide both sides by 3 we get x=5
now we know x=5 4x+1=21 and 9x-4=41
*drops microphone*
Answer:
TR = 12
=> 3x + 2 =17
=> x = 5
We have QT = QV (because QTV is an isosceles triangle)
=> QT = 4x+1=4x5+1=21 units
We have TS = SV (because TSV is an isosceles triangle)
=>SV = 9x-4= 9x5-4=41 units

We can once again use right triangle trig:
We are given the hypotenuse and adjacent sides, so cosine must be used:
cosA = A / H
thus:
cosA = 9/11
Use inverse trig to solve:
cos⁻¹(9/11) ≈ 35.1°

X2+y2-6x+2y-39=0 what is the radius and the center
Answer:
(centre = (3, - 1 ) and radius = 7
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² - 6x + 2y - 39 = 0 ( collect x/ y terms and add 39 to both sides )
x² - 6x + y² + 2y = 39
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(- 3)x + 9 + y² + 2(1)y + 1 = 39 + 9 + 1
(x - 3)² + (y + 1)² = 49 ← in standard form
with centre (3, - 1 ) and r = [tex]\sqrt{49}[/tex] = 7

Find a value for C that will give the following system no solution:
3x-2y=3
6x+cy=4
Answer:
c = - 4
Step-by-step explanation:
Nothing else matters except that the number associated with the y value in equation one = 1 and the number in front of x is known in equation 1. Then we'll get around to looking at c
Add 2y to both sides of equation 1 (the top equation)
3x - 2y + 2y = 3 + 2y
3x = 2y + 3
Now divide both sides of the equation by 2
3x/2 = y + 3/2
What's in front of x? It is (3/2)
So divide both sides of 6x + cy = 4 by c
6x/c + y = 4/c
Now put 6x/c on the right hand side so y is by itself.
y = -6x/c + 4/c
What do you have to do now?
You must equate -6x/c = 3/2x
Why?
The slopes have to be the same so the lines are parallel and never cross. That will give no solutions.
-6x/c = 3x / 2 Divide both sides by x
-6/c = 3/2 Cross multiply
3c = - 6 * 2 Combine
3c = - 12 Divide by 3
c = - 12/3
c = - 4
