Answer:

[tex]\frac{5\sqrt{34}}{34}[/tex]

Step-by-step explanation:

The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = [tex]\sqrt{a^{2} + b^{2} }[/tex].

In the equation you'd write that as r = [tex]\sqrt{10^{2} + 6^{2}[/tex] which can be simplified to [tex]\sqrt{136[/tex].

You end up with [tex]\frac{10}{\sqrt{136} }[/tex] and you simplify this by doing [tex]\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }[/tex], ending with the result of [tex]\frac{5\sqrt{34}}{\sqrt{34} }[/tex].

Answer:

100

Step-by-step explanation:

X and 80 make a supplmentary angle which means when added, it will equal 180°. We can make an equation and solve.

180 - 80 = 100

Best of Luck!

Answer:

100 degrees

Step-by-step explanation:

a line adds up to 180

80+x=180

x=100

Answer:

B) 69°

Step-by-step explanation:

The missing measure is supplementary angle of 111° which means their sum is equal to 180°

180 - 111 = 69.

Answer: 176

Step-by-step explanation:

GIven: In each stand,

It has 2 rows of 20 games.

It has 2 rows of 24 games.

Total number of video games in each stand = 2 x 20 + 2x 24

= 40+48

= 88

Since there are 2 identical stands,

then toral video games in 2 stands = 2 (88)= 176

Hence, the total number of video games Cameron's stands can hold= 176.

Answer:

Thus, the statement is False!

Step-by-step explanation:

When the domain of a function has an infinite number of values, the range may not always have an infinite number of values.

For example:

Considering a function

[tex]f(x) = 5[/tex]

Its domain is the set of all real numbers because it has an infinite number of possible domain values.

But, its range is a single number which is 5. Because the range of a constant function is a constant number.

Therefore, the statement ''When the domain of a function has an infinite number of values, the range always has an infinite number of values'' is FALSE.

Thus, the statement is False!

Answer: B

Step-by-step explanation:

Answer:

[tex]\dfrac{4}{3}[/tex]

Step-by-step explanation:

Number of boxes of paper = 4

Number of printer = 3

We have to find the number of pages in each printer.

Let the number of pages in each box be 1.

Total number of pages in 4 boxes = 4

3 printer will have pages = 4

1 Printer will have pages = [tex]\dfrac{4}{3}[/tex]

Hence, pages each printer will have is equal to [tex]\dfrac{4}{3}[/tex].

Answer:

x = - 12

Step-by-step explanation:

Since line with identical signs are parallel and a transversal is making right angle with one of the lines.

So,

[tex](x + 102 ) \degree= 90 \degree \\ \\ x + 102= 90 \\ \\x = 90 - 102 \\ \\ x = - 12[/tex]

Answer:

1.         x=2+3y/2

2.         x=−3/2+4y

The probability that both marbles are blue is 9 percent.

It is given that 12 marbles in a bag, four of them are blue and the rest are green.

To find the probability that both marbles are blue.

The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

Let both the marble be blue for event A.

P(A)=2C4/2C12     (combination formula)

=6/66

=1/11

≅0.09

=9percent.

So ,the probability that both marbles are blue is 9 percent.

Answer:

y = 4 x 6 + 8

Step-by-step explanation:

the 4 is the amount of dogs that arent big

the is 6 is the amount that she gets for walking the normal sized dogs

the 8 dollars is the amount that she gets for walking the big dog

so you would multiply 4x6 which would give you 24
then add the 8 and you will get 32
so that would mean she gets 32$ every saturday

Answer:

x = 45°

Step-by-step explanation:

From the triangle given in the picture,

It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.

By the property of isosceles triangle,

Opposite angles of the equal sides are equal in measure.

By triangle sum theorem,

x + x + 90° = 180°

2x + 90 = 180

2x = 180 - 90

x = [tex]\frac{90}{2}[/tex]

x = 45°

x=3/2y + 2
