616

Step-by-step explanation:

22 * 28 = (25 - 3)(25 + 3) = 25^2 - 3^2 = 625 - 9 = 616

Answer:

Step-by-step explanation:

1) Divide 50 by 7

2) Take that number and multiply it by 6.5 km

This works because the result of dividing 50/7 multiplied by 7 will give you 50, and if you multiple the result by 6.5 you will get your answer!

Answer:

MN║OP

Step-by-step explanation:

From the picture attached,

MP and OP are the two lines and OT is a transversal intersecting these lines at R and S.

Angles on the same side of transversal OT measure the same as 45°

By the converse of corresponding angles theorem,

"If the corresponding angles formed by the transversal with the lines, are equal in measure, then the lines are parallel."

Therefore, MN║OP is the answer.

Answer:

the line is dashed and you shade up

Step-by-step explanation:

With a > and < it is dashed because it is not equal but if they did also equal it would be solid.

you shade above because it is > and the greater y values would be above the line.

Answer:

d

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.

Given that, |u| = 10 at an angle of 45° and |v| = 13 at an angle of 150°.

We need to find magnitude and direction angle of w.

We have, w = u + v, θ=45° and ϕ=150°.

[tex]u_{x}[/tex]=|u|cosθ=10cos45°=7.071

[tex]u_{y}[/tex]=|u|sinϕ=[tex]u_{y}[/tex]=|10sin45°=7.071

[tex]v_{x}[/tex]=|v|cosθ=13cos150°=-11.25833

[tex]v_{y}[/tex]=|v|sinϕ=[tex]v_{y}[/tex]=13sin150°=6.5

Using this information, we get

[tex]R_{x} =u_{x} +v_{x}[/tex]=7.071-11.25833=-4.18733

[tex]R_{y} =u_{y} +v_{y}[/tex]=7.071+6.5=13.571

Direction angle=[tex]tan^{-1}[/tex](Ry/Rx)

Direction angle=[tex]tan^{-1}[/tex](13.571/-4.18733)

=-72.8239 or 107.1476≈107.1

Now, [tex]|w|=\sqrt{(|u|cos \theta +|v|cos \phi )^{2}+(|u|sin \theta +|v|sin \phi )^{2}}[/tex]

=[tex]|w|=\sqrt{(10cos45\textdegree +13cos150\textdegree )^{2}+(10sin 45\textdegree+13sin150\textdegree)^{2}}=14.2026[/tex]

Here, the direction angle is 107.1° and the magnitude is 14.2. Therefore, option D is the correct answer.

Answer:k i’ll help i just can’t see that far what does it say

Step-by-step explanation:

Answer:

there are 280 black sheep

Given:

Rate of commission = 10% on each sale

Commission = $450

To find:

The total sales.

Solution:

Let the total sales be x. Then,

Commission = 10% of total sales

[tex]450=\dfrac{10}{100}\times x[/tex]

[tex]450=\dfrac{1}{10}\times x[/tex]

Multiply both sides by 10.

[tex]4500=x[/tex]

Therefore, the total sales is $4500.

The last week sales of Mr. Jones who receives 10% commission on each sale that he makes is $4500.

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

Supose Mr. Jones sold x dollar item last week. As Mr. Jones receives 10% commission on each sale that he makes and he earned $450 last week in commissions.

Thus, the 10 percent of x is equal to the $450. It can be written in expression form as,

[tex]\dfrac{10}{100}\times x=450\\x=\dfrac{45000}{10}\\x=4500[/tex]

Hence, the last week sales of Mr. Jones who receives 10% commission on each sale that he makes is $4500.

Answer:

92%

Step-by-step explanation:

a Percent is equal to 1/100

so we need to make the denominator 100

so you multiply both the denominator and numerator by 4

4*23=92

4*25=100

92/100

which is also 92%

Answer:

x=-4 y=4

(-4,4)

Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

Given that Δ JKL  is equilateral then the 3 sides are congruent.

Equate any 2 sides and solve for x, that is

13x + 5 = 8x + 35 ( subtract 8x from both sides )

5x + 5 = 35 ( subtract 5 from both sides )

5x = 30 ( divide both sides by 5 )

x = 6

An equilateral triangle is a triangle where all three sides are equal.

The value of x is 6.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

An equilateral triangle is a triangle where all three sides are equal.

∆JKL is an equilateral triangle.

JK = 13x + 5

KL = 17x – 19

JL = 8x + 35

Now,

JK = 13x + 5

KL = 17x – 19

JK = KL

13x + 5 = 17x - 19

5 + 19 = 17x - 13x

24 = 4x

x = 6

Thus,

The value of x is 6.
