What is the sum of 5.3 x 10 to the fifth power and 3.8 x 10 to the fourth power in scientific notation
Answer:5.6 x 10^5
Step-by-step explanation:
When ever we hear sum, what comes to our mind must be addition
Here we are Adding 5.3 x 10 to the fifth power= 5.3 x 10^5 to
3.8 x 10 to the fourth power = 3.8 x 10^4
First,
Expanding the scientific notation we have that
5.3 x 10^5 = 530,000
3.8 x 10^4= 38,000
Add = 568,000
Putting back in Scientific notation we have 568000 = 5.6 x 10^5
Answer:
5.68 x 10 to the 5th power

Jackson has a gift card to Target for $25, he buys a $5 Lego toy each time he goes Write an equation to represent the money Jackson spends on his gin card. How much money will he have left after 3 trips to Target?
Answer:
x = every time he goes to target.
y = the amount he has left.
25 - 5x = y
After 3 trips, he will have 10 dollars left.
Step-by-step explanation:
25 - 5(3) = y
25 - 15 = 10
Answer:
10
Step-by-step explanation:
25 - 5, 20 - 5, 15 - 5 = 10

A man weighing 800 N is hanging from a 2 mm diameter titanium wire with a cross-section of 3 x 10^-6 m^2. Will the wire break?
Answer:
Since stress is greater than ultimate strength, the wire will break.
Step-by-step explanation:
The titanium wire is experimenting an axial load. Ultimate strength equals [tex]2.20\times 10^{8}\,Pa[/tex]. The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress ([tex]\sigma[/tex]), measured in pascals, in the wire with circular cross-section is:
[tex]\sigma = \frac{4\cdot F}{\pi\cdot D^{2}}[/tex] (1)
Where:
[tex]F[/tex] - Axial force, measured in newtons.
[tex]D[/tex] - Cross-section diameter, measured in meters.
Please notice that axial force is the weight of the man hanging from wire.
If we know that [tex]F = 800\,N[/tex] and [tex]D = 0.002\,m[/tex], then the axial stress experimented by the titanium wire is:
[tex]\sigma = \frac{4\cdot (800\,N)}{\pi\cdot (0.002\,m)^{2}}[/tex]
[tex]\sigma \approx 2.546\times 10^{8}\,Pa[/tex]
Since stress is greater than ultimate strength, the wire will break.

How can you show that two quantities have a proportional relationship?
Answer:
If they can be expressed in the form of y=kx, they are proportional. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.
At the county fair, 210 snow cones were sold for a total of $540. Large snow cones (x) cost $3.00 each and small snow cones (y) cost $2.00 each. Which equations below could be used to model this system of equations? Select all that apply.
Answer:
3x + 2y = 540
x + y = 210
Step-by-step explanation:
Giving the following information:
At the county fair, 210 snow cones were sold for a total of $540. Large snow cones (x) cost $3.00 each and small snow cones (y) cost $2.00 each.
We can establish the following system of equations:
x= number of large snow cones sold
y= number of small snow cones sold
3*x + 2*y = 540
x + y = 210

How many solutions does
y=f(x)
−y=−f(x)
have
the options are
no solution
infinitely many solutions
one solution
Answer:
Infinitely many solutions
Step-by-step explanation:
There are 2 variables in this equation. Since, there are infinite many numbers, we can substitute them in x & y. This will lead to an infinite number of solutions.
Each employee in a company is either right-handed or left-handed.
32 of the 54 employees are female.
18 of the 41 right-handed employees are male.
Complete the frequency tree for this information.
Answer:
23 females are right handed and 9 are left handed
Step-by-step explanation:
So to get this answer :
18 OF THE 41 RIGHT HANDED EMPLOYEES ARE MALE.
The statement means that there are 41 right handed employees and 18 of those are male thus the remaining are FEMALE.
To find the number of right handed employees who are female just subtracted 18 from 41 ( becaus etotal number of right handed males is 18 and the total number of right handed employees is 41.)
SO 23 FEMALES IN THE COMPANY ARE RIGHT HANDED.
Because 23 females are right handed that means to get the number of left handed females you subtract the total number of right handed females from the total number of females in the company THUS:
32 - 23 = 9 LEFT HANDED FEMALES

Answer:
Step-by-step explanation:
[tex](1/5k)^2=1/5^2*k^2[/tex]
[tex]1/25*k^2=\frac{k^2}{25}[/tex]
Answer: [tex]\frac{1}{25}k^2[/tex]
This is equivalent to [tex]\frac{k^2}{25}[/tex]
In decimal form, this is equivalent to 0.04k^2
==================================
Work Shown:
We have the two pieces 1/5 and k, all in the parenthesis being squared.
Square each piece
Squaring the piece 1/5 leads to (1/5)^2 = 1/25, since 5^2 = 25squaring the k value leads to k^2So overall, we end up with the answer [tex]\frac{1}{25}k^2[/tex] which is equivalent to saying [tex]\frac{k^2}{25}[/tex]
In decimal form, this is 0.04k^2 because 1/25 = 0.04

A rectangle has a width of 2/7 cm and a length represented by the expression a+4. Find the area. (tell me how btw! and i will give brainliest.)
answer:
we know the formula for area is,
L x W
so,
2/7 (a+4) = area
solve this by distributing the 2/7,
you get = 2/7a + 8/7
the area is 2/7a + 8/7

Answer:
B, 7/24
Step-by-step explanation:
(x=theta)
sec(x) = 1/cos(x) so 1/cos(x) = 25/24
[tex](\frac{1}{cosx})^-1 = (\frac{25}{24} )^-1\\\\cos(x) = 24/25[/tex]
Then use the cos^-1 function on your calculator to find out theta.
Then tan your found value of theta.
You should find that tan (theta) = 7/24

Answer:
yes they are
Step-by-step explanation:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
