Answer:

l and k are both 70

Step-by-step explanation:

l and k are both the same angle.

130+90= 220

360-220=140

140/2=70

therefore l and k are both 70

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.

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

Circumference = 2 x pi x r

Circumference = 2 x 3.14 x 3.5m

Circumference = 21.98

Round to 22m

The answer is c. 22m

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

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:

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.

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".

Step-by-step explanation:

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:

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

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
