Answer:
-40
Step-by-step explanation:
Plug in 9 for x.
Use Order of operations
-10(9) = -90
-90 + 50 is the same thing as saying 50 - 90
we can simplify by splitting the -90 in to a -40 and a -50
the new equation could be 50 - 50 -40.
50 - 50 = 0
0-40 = -40

Belinda jogged 1.5 km, then walked 500 m. Write the ratio of distance jogged to distance walked in simplest form.
Answer:
3:1
Step-by-step explanation:
Given data
Distance jogged= 1.5km
Distance walked= 500m= 0.5km
Hence the ratio of distance jogged to distance walked is
=1.5/0.5
=3/1

Find the area of the shaded region
Answer:
Area = 28.43 cm²
Step-by-step explanation:
area of square = 11.5 x 11.5 = 132.25 cm²
area of circle = πr² = (3.14)(5.75²) = 103.82 cm²
Area= 132.25 - 103.82 = 28.43 cm²
Answer:
28.38 cm²
Step-by-step explanation:
Area of square
a = 11.5^2
a = 132.25
The corners are 4 quarter circle
which makes a complte circle
a = πr^2
a = π(11.5/2)^2
a = 103.8689071093
Area shaded
a = 132.25 - 103.8689071093
a = 28.3810928907
Rounded
a = 28.38 cm²

What is the probability of rolling a 6 and then a 7 on a number cube?
Answer:
0%, there is no chance you can roll a 7 on a number cube with 6 sides.
If you meant a 5 and then a 6, or 2 rolls subsequently, it would be 1/36.
Step-by-step explanation:
1/6*1/6=1/36

How many different 12-letter arrangements can be made using the letters in the word CARELESSNESS?
From 12 different letters, 3326400 arrangements can be made using the letters in the word CARELESSNESS.
What is permutation?When the order of the arrangements counts, a permutation is a mathematical approach that establishes the total number of alternative arrangements in a collection. Choosing only a few items from a collection of options in a specific sequence is a common task in arithmetic problems.
Among the 12 letters in CARELESSNESS,
there are 4 S’s, 3 E’s, and 1 each of C, A, R, L, N.
There are 12! = 479,001,600 arrangements (permutations) of the 12 letters,
most of which are identical because of repeated letters.
In order that each permutation be distinct, repeat letters have to be accounted for.
4 S’s be in 4! = 24 ways,
3 E’s, in 3! = 6 ways.
And 1! = 1 way.
Distinct permutations as requested,
thus = 12!/(3!)(4!)(1!)
= 3326400.
Therefore, 3326400 different 12-letter arrangements can be made using the letters in the word CARELESSNESS.

What are the values of c and d in the matrix subtraction below? [ 6 8 -11 15 ]-[c+2 3 -5 d-4 ]=[ 22 5 -6 17] C=-14 d= -6 c=-18 d= -6 c=-14 d=2 c=-18 d=2
Answer:
c=-18 d=2
Step-by-step explanation:
[ 6 8 -11 15 ]-[c+2 3 -5 d-4 ]=[ 22 5 -6 17]
The equation tells that when the two matrices are subtracted we get the resultant matrix.
Each element of the first matrix corresponds to each element of the second matrix
From above
6- (c+2)= 22
6- c-2= 22
4-c= 22
-c= 22-4
-c= 18
c= -18
And
15-( d-4)= 17
15- d+4= 17
19-d= 17
-d= 17-19
-d= -2
d= 2

Please help me find the value of x!
Exact Answer: x = 16/3
Approximate Answer: x = 5.333
=======================================================
Work Shown:
base = 3x-1
height = x
area of triangle = (base*height)/2
40 = x*(3x-1)/2
40*2 = 3x^2 - x
80 = 3x^2 - x
0 = 3x^2 - x - 80
3x^2 - x - 80 = 0
Now apply the quadratic formula
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-1)\pm\sqrt{(-1)^2-4(3)(-80)}}{2(3)}\\\\x = \frac{1\pm\sqrt{961}}{6}\\\\x = \frac{1\pm31}{6}\\\\x = \frac{1+31}{6} \ \text{ or } \ x = \frac{1-31}{6}\\\\x = \frac{32}{6} \ \text{ or } \ x = \frac{-30}{6}\\\\x = \frac{16}{3} \ \text{ or } \ x = -5\\\\x \approx 5.333 \ \text{ or } \ x = -5\\\\[/tex]
A negative height doesn't make sense, so we ignore x = -5
The only solution is x = 16/3 which approximates to x = 5.333
