Answer:
13.5 centimeters
Step-by-step explanation:
Solution #1:
15 * 0.9 = 13.5
Solution #2:
15 * 0.1 = 1.5
15 - 1.5 = 13.5
Determine the value of the expression
Find the missing side length.
12
15
Answer:
you need to show the shape or somet or else I can't rlly help
Answer:
If the hypotenuse is 15 and one of the sides is 12, the answer is 9.
If these are the side lengths, the hypotenuse is square root of 369, which is about 19.21
Step-by-step explanation:
Solve the equation for x.
x2 = 36
The solutions to the equation are
and
x2=36
We move all terms to the left:
x2-(36)=0
We add all the numbers together, and all the variables
x^2-36=0
a = 1; b = 0; c = -36;
Δ = b2-4ac
Δ = 02-4·1·(-36)
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ‾‾√=144‾‾‾‾√=12
x1=−b−Δ√2a=−(0)−122∗1=−122=−6
x2=−b+Δ√2a=−(0)+122∗1=122=6

Answer:
x = -6 or +6
Step-by-step explanation:
You know from your multiplication tables that 6×6 = 36, so one answer is ...
x = 6
You also know that the product of two negative numbers is positive, so another answer is ...
x = -6
__
Check
x² = 6² = 6×6 = 36
x² = (-6)² = (-6)×(-6) = 36
_____
Alternate approach
If you like, you can rewrite the equation as ...
x² -36 = 0
This can be factored to ...
(x -6)(x +6) = 0
The zero product rule tells you this product will only be zero if one or the other factors is zero.
x -6 = 0 ⇒ x = 6
x +6 = 0 ⇒ x = -6
The two solutions are x = ±6.

Answer:
27/7 or 3 6/7
Step-by-step explanation:
3/7 divided by 1/9 = 27/7
rounded to 3
Have a nice day
The 0.317 spray bottle did she us.
It is required to find how much of the bottle did she use.
What is fraction?A fraction having whole numbers for the numerator and denominator. A fraction is a number of the form: ab where a and b are integers and b≠0. It represents the division of two numbers.
Given:
We know that total =1
For a cleaning solution=3/7 of a spray bottle
Used=1/9
According to given question we have,
Subtract the fractions
3/7 - 1/9
Calculate the difference,
=20/63
=0.317

You have $500 in a savings account. How long will it take to double that
amount at an 8% annual interest rate?
Answer:
Step-by-step explanation:
The formula for compound annual interest is A = P(1 + r)t where
A = Accumulated or final amount (double $500 = $1000)
P = Principal or original amount ($500)
r = Rate as a decimal (0.08)
t = Time in years
1000 = 500(1 + 0.08)t
2 = 1.08t
Take the logarithm of both sides. I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well
ln(2) = ln(1.08t)
ln(2) = t*ln(1.08)
t = ln(2)/ln(1.08)
t = 9.0065 years
Check: 500*1.089.0065 = $1000

A 7.12 µC charge is moving at one half the speed of light perpendicular to a magnetic field of 4.02 mT. How large is the force on the charge?
A.) 4.29 N
B.) 32.90 x 10^(1) N
C.) 4.29 x 10^(12) N
D.) 1.00 x 10^(16) N
Answer:
The correct option is A: 4.29 N.
Step-by-step explanation:
The magnetic force is given by:
[tex] F = qv\times B = qvBsin(\theta) [/tex]
Where:
q: is the charge = 7.12x10⁻⁶ C
v: is the speed = c/2 = 1.5x10⁸ m/s
B: is the magnetic field = 4.02x10⁻³ T
θ: is the angle = 90° (the speed is perpendicular to the magnetic field)
Hence, the force on the charge is:
[tex]F = qvBsin(90) = 7.12 \cdot 10^{-6} C*1.5 \cdot 10^{8} m/s*4.02 \cdot 10^{-3} T = 4.29 N[/tex]
Therefore, the correct option is A: 4.29 N.

What is the value of 6x+7y−5 when x = 2 and y = 3?
Answer:
28
Step-by-step explanation:
6(2) + 7(3) - 5
12 + 21 -5
It's a good idea to get into the habit of using parenthses
when substituting numbers in for variables.
Since x = 2 and y = 3, 6x + 7y - 5 is 6(2) + 7(3) - 5.
Simplifying from here, we get 12 + 21 - 5 or 33 - 5 which is 28.
Four basketballs and six baseballs cost $44. Five basketballs and four baseballs costs $48. Determine the cost for one basketball and one baseball.
Answer:cost for basket ball= $8 and
cost of baseball = $2
Step-by-step explanation:
Step 1
Let the cost of basket ball be represented as x
and cost of baseball = y such that
Four basketballs and six baseballs cost $44 will be expressed as
4x+ 6y= 44 --- eqn 1 also
Five basketballs and four baseballs costs $48 will be expressed as
5x+ 4y= 48--- eqn 2
Step 2
Having obtained two expressions we can now sole
4x+ 6y= 44 --- eqn 1
5x+ 4y= 48--- eqn 2
multiplying eqn 1 by 5 and eqn 2 by 4
20x+ 30y =220---- eqn 3
20x+ 16y=192-----eqn 4
subtracting equation 4 from 3 we now have
14y=28
y= 28/14
y=2 = $2
from equation 1
4x+ 6y= 44, putting the value of y=7 to find x
4x+ 6(2)= 44
4x+12= 44
4x= 44-12
4x=32
x= 32/4
x=8=$8
cost for basket ball= $8 and
cost of baseball = $2
Copy and insert two pairs of brackets to make the equation true. 1 + 2 x 3 + 4 x 5 +6 x 7+ 8 x 9 = 505
Answer and explanation:
1For BODMAS to apply to the equation and five us the correct result of 505, we did have to place the brackets where they should be and show the order of operations using the BODM
1 + 2 x 3 + 4 x 5 +6 x 7+ 8 x 9 = 505
