find (0.05)^2 I need the explain
Step-by-step explanation:
(0.05)²
CHANGE 0.05 INTO SCIENTIFIC NOTATION
= (5 × 10^-2)²
SQUARE IT OFF EACH NUMBER
= 5² × (10^-2)²
=25 × 10^-4
=0.025
Answer:
.05×.05=.0025 because it is squared
answer this please:)

5x^3 + 6x^2 - 45x - 54
x^2( 5x + 6) -9(5x-6)
(5x+6)(x^2 - 9)
5x+6=0 x^2-9=0
5x= -6 x^2= 9
x= -6/5 x= -3 or 3
solve the system of equations by the substitution method .
y=5x+8
y=8x+9
Answer:
rearrange the question
y - 5x = 8.................(1)
y - 8x = 9..................(2)
make y the subject formula in eqn. (1)
y = 8 + 5x................(3)
substitute
8 + 5x - 8x = 9
-3x = 1
x = -⅓
y = 8 + 5x
y = 8 + (-⅓)
y = 23/3

x(x-1)-x^2+2x=5 :))))))
Answer:
[tex]x(x - 1) - {x}^{2} + 2x = 5 \\ {x}^{2} - x - {x}^{2} + 2x = 5 \\ \therefore \: x \: = 5[/tex]
Answer:
x=5
Step-by-step explanation:
[tex]x(x-1)-x^2+2x=5[/tex]
expand by using distributive property
[tex]x^2-x-x^2+2x=5[/tex]
simplify
x=5
check work by substituting 5 into the original equation and simplify
use PEMDAS
[tex]5(5-1)-5^2+2(5)=5[/tex]
[tex]5(4)-25+10=5[/tex]
add and subtract (left to right)
20-25+10=5
5=5
The equation is true, thus x=5
In how many ways can 8 diplomats be seated at a round table?
A)40,320
B)5,040
C)720
Answer:
5040Step-by-step explanation:
Now, imagine a specific arrangement. Now, have everyone get up and move one seat to their right. That arrangement was counted separately from the first one in the 8! but it’s really the same since if each person looks to their left and their right, they’re sitting next to the same person. There are 8 such “identical rotations” for each possible seating arrangement so the total number of seatings is 8! / 8 = 7! = 5040.HOPE IT HELPS

Graph 4x +3x=11 and x=y+1 as 2 separate lines that intersect.
Answer:
Step-by-step explanation:
So first of all, you can rearrange your equations:
4x + 7x = 11 can be rearranged and simplified to x = 11/7
x = y + 1 can be rearranged to y = x - 1
Then you can graph them like normal by plugging in points. It should look like the following picture

Which expression shows the first step in applying the distributive property to
6(8-3)?
A.
6.8 +6
B.
1 2 3
(6 - 8) (6-1
-
o D. 6.8-6. 1 / 3
C.
6
- 6-8
Answer:
Answer: Option D
Answer: Option DStep-by-step explanation:
• In distributive property, we multiply the factor to each term in the bracket. So that the reverse is true.
Take an example;
[tex] \dashrightarrow \: { \rm{x(y + z)}}[/tex]
• To apply distributive property, mulyiply both y and z by x following the addition operation.
summary:
[tex] \dashrightarrow \: { \rm{xy + xz}}[/tex]
→ The expression above is the expansion using distributive property.
• Back to the question, we are given a factorised expression;
[tex]{ \rm{6(8 - \frac{1}{3} )}} \\ [/tex]
• To apply the distributive property, multiply 8 and ⅓ by 6:
[tex] \dashrightarrow \: { \boxed{ \boxed{ \rm{ \: (6 \: • \: 8 - 6 \: • \: \frac{1}{3}) }}}} \\ [/tex]

A teacher said that 68% would be the
lowest passing test score. Kanisha got
19 out of 28 problems correct. What
was her test score? Was it a passing
score?
A percentage is out of 100%.
19 (questions right) / 28 (total) = 0.67857142857
Round to the tenth, 67.9.
67.9%, not a passing score.Answer:
Kanisha's test score is approximately 67.8571 percent.
Step-by-step explanation:
19/28 is about 67.8571, just under the 68 percent passing score. However, if her test score is rounded up, it will exactly meet the lowest passing score.

Step-by-step explanation:
63+36+X = 180 (interior angles of a triangle equal 180)
X = 180-99
X= 81
X+Z= 180(angles on a straight line adds up to 180)
81+y= 180
Z=180-81
Z =99
13+Z+Y=180
13+99+Y=180
Y=180-112
Y=68

Step-by-step explanation:
1. Given that Javier's pay rate is $10.25 per hour, let's find the combined amount he earned from Monday and Tuesday by multiplying the hours worked by 10.25.
[tex]2.4 * 10.25[/tex] [tex]24.6[/tex] [tex]3.8*10.25[/tex] [tex]38.95[/tex]2. Now, let's add 24.6 and 38.95 to get how much he earned:
[tex]24.6+38.95[/tex] [tex]63.55[/tex]Therefore, Javier earned 63.55 dollars and cents on those two days.
