Answer:

101.76

Step-by-step explanation:

Answer:

x=13

y=14

Step-by-step explanation:

We know that angle JNK is equal to angle MNL. We also know that angle JNK and angle KNL are supplementary.

Knowing this, we can write two equations: [tex]4x-1=3y+9[/tex] and [tex](4x-1)+(2x+6y+19)=180[/tex]. We can solve for y in the first equation. Subtracting 9 from both sides gives us [tex]4x-10=3y[/tex]. Dividing both sides by 3 gives us [tex]\frac{4x-10}{3} =y[/tex].

We can plug that in to the second equation to get [tex](4x-1)+(2x+6(\frac{4x-10}{3} )+19)=180[/tex]. Expanding the second parenthesis, we get [tex]2x+8x-20+19[/tex] which equals [tex](10x-1)[/tex]. We now have [tex](4x-1)+(10x-1)=180[/tex]. Expanding gives us [tex]14x-2=180[/tex]. Adding 2 to both sides gives us [tex]14x = 182[/tex]. Dividing both sides by 14 gives us [tex]x=13[/tex].

We can now plug 13 into the above equation to solve for y. [tex]y= \frac{4*13-10}{3}[/tex] Solving that gives you [tex]y=14[/tex].

Answer:

9 weeks at least to have at least 50 dollars.

Step-by-step explanation:

Well 6 dollars each week and to get AT LEAST 50 dollars you need to save for 9 weeks.

Well 9*6=54

If you do it for 8 you’d only get 48 which is not at least 50 but 54 is.

So 9 weeks is the final answer.

50≤54

50 isn’t less then 48

Answer: surface area

A = 56 π cm^2

Step-by-step explanation:

A = 56 π cm^2

you can stop here and write our answer as 56π Or we can plug in 3.14 and multiply. 56*3.14 = 175.84cm^2

Answer:

4. the answer is 5.4 which is between 5 and 6.

5. the answer is C.

Step-by-step explanation:

for #4 you just had to divide 27 by 5, and for #5 both numbers are positive so they are in the first quadrant.    

Answer:

y = 29

Step-by-step explanation:

x/2 + 3 = y/3 - 2

28/3 ÷ 2 = 14/3

14/3 + 9/3 = y/3 - 6/3

23/3 + 6/3 = y/3

29/3 = y/3  ∴ y = 29

Hints on solving trigonometry problems:

If no diagram is given, draw one yourself.

Mark the right angles in the diagram.

Show the sizes of the other angles and the lengths of any lines that are known

Mark the angles or sides you have to calculate.

Consider whether you need to create right triangles by drawing extra lines. For example, divide an isosceles triangle into two congruent right triangles.

Decide whether you will need Pythagorean theorem, sine, cosine or tangent.

Check that your answer is reasonable. The hypotenuse is the longest side in a right triangle.

How to use the tangent ratio to find missing sides or angles?

Example:

Step-by-step explanation:

We have 2 Semicircular. area of each one :

[tex]\pi \: \times \: r[/tex]

r = 2.5ft and pi=~3 ==> 7.5×2=15ft (area of two Semicircular)

the area of triangle = 5 + 5 + 6 = 16ft

area of the figure = 16 + 15 = 31ft

Answer:

[tex]in \: this \: shape \: you \: have \: two \: pieces \: one \: square \: ad \: half \: of \: circle \\ area \: of \: circle = 12 \times 12 = 144 \\ area \: of \: hafl \: of \: circle = 12 \times 12 \times 0.25 \times 3.14 = 113.04 \\ whole \: area = 144 + 113.04 = 257.04[/tex]

Answer: E. 200.5 ft

so first you’d find the area of the square which is 12 x 12 = 144 (area = length x width)

next, find the radius of the semi circle which is 12 divided by 2 (because we used the measurements from the square and the diameter is 12 and radius is half of diameter)

pretend your solving for a full circle and then divide it by 2 to get the answer for the semi circle since a semi circle is half of a circle (formula for circle A = pi r^2)

area of circle = 113.04 divided by 2 to get semi circle = 56.5

then add both areas together

56.52 + 144 = 200.5
