can someone help i have several questions like this i also need the work shown

Answer: B. 40

Hope this helps

Answer:

B 17.5 ft

Step-by-step explanation:

tangent = opposite / adjacent

tan 35° = h / 25

multiply both sides by 25

h = 25 (tan 35°)

tan 35° = 0.70 (from your calculator)

h = 25 (0.70)

h = 17.51 ft.

Answer:

x = 10, y = 12

Step-by-step explanation:

Answer:

{-5/4, 8}

Step-by-step explanation:

We are given (4u + 5)(8 - u) = 0.  Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:

4u + 5 = 0 leads to u = -5/4, and

8 - u = 0 leads to u = 8.

The solutions are {-5/4, 8}

Answer: 12.57 ft

Step-by-step explanation:

Circumference of circle with radius of 4ft.

= π * radius * 2

= 22/7 * 4 * 2

= 25.14 ft

Circumference of circle with radius of 6ft.

= 22/7 * 6 * 2

= 37.71 ft

Difference = 37.71 - 25.14

= 12.57 ft

The ratio 4:7 in the form n:1 is [tex]\frac{4}{7} : 1[/tex] .

What is unit fraction?

A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore the reciprocal of a positive integer, 1/n. Examples are 1/1, 1/2, 1/3, 1/4, 1/5, etc.

According to the question

The ratio 4:7  in the form n:1

i.e

[tex]\frac{4}{7} = \frac{n}{1}[/tex]

n = [tex]\frac{4}{7}[/tex]

Now, the unit fraction

The ratio is

= [tex]\frac{4}{7} : 1[/tex]

Hence, the ratio 4:7 in the form n:1 is [tex]\frac{4}{7} : 1[/tex] .

To find:

The solution of the given inequality.

Solution:

We have,

[tex]q+12-2(q-22)>0[/tex]

It can be written as:

[tex]q+12-2q+44>0[/tex]

[tex](q-2q)+(12+44)>0[/tex]

[tex]-q+56>0[/tex]

Subtract 56 from both side.

[tex]-q>-56[/tex]

Multiply both sides by -1 and change the inequality sign.

[tex]q<56[/tex]

Therefore, the correct option is D.

Step-by-step explanation:

The solution of the given equation is x = 2.1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given that, an equation, 3ˣ = 10, we need to find the solution of it,

So, solving for x,

3ˣ = 10

Taking log both sides,

㏒ 3ˣ = ㏒ 10

Since, ㏒ aⁿ = n ㏒ a

Therefore,

x ㏒ 3 = ㏒ 10

x = ㏒ 10 / ㏒ 3

x = 1/0.477

x = 2.095

x ≈ 2.1

Hence, the solution of the given equation is x = 2.1

Step-by-step explanation:

Answer:

m=4/-3

Step-by-step explanation:

the equation for slope (m) when given two points is (y2-y1)/(x2-x1)

we are given the points (9,3) and (6,7)

we can label the points:

x1=9

y1=3

x2=6

y2=7

now substitute into the equation

m=(7-3)/(6-9)

subtract

m=4/-3

the slope is 4/-3

Answer:

71.13

Step-by-step explanation:

The half area of a circle is A = 1/2 * pi*r^2 = 1/2 * pi * 3^2 or 9

The trapezoid is a rectangle and a triangle. Rectangle is 8*6 and the triangle is 6*(11 - 8) * 1/2

The total is 1/2 * pi * 9 + 8*6 + 6*(11 - 8) * 1/2 = 71.13

If I have 48 cards and and gave 10 to my friend and I have 38 left. what fraction of original number of card do I have left.

Answer:

0.7917

Step-by-step explanation:

If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards

Given that :

Total number of cards = 48

Number given to friend = 10

Number of cards left = 48 - 10 = 38

Number of cards left / original number of cards

38 / 48

= 0.7917
