How do I solve for the missing angle?!
And please include explanations​ on how you got the answer

Answers

Answer:

75°

Step-by-step explanation:

In triangle FBG, one angle is 36.  That means the other two must total 180-36=144.  Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.

In triangle JDI, one angle is 39.  That means the other two must total 180-39=141.  Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5

We now have 4 of the interior angles.  Pentagons have an interior total of 540.  540-108-108-109.5-109.5=105

x is the supplement of 105.  180-105=75

Ten baseballs weigh 1,417.4 grams. About how much does 1 baseball weigh? Round your answer to the nearest tenth of a gram. Round your answer to the nearest gram.. Which answer would you give if someone asked, "About how much does a baseball weigh?" Explain your choice.

Answers

Answer:

See explanation

Step-by-step explanation:

If all the ten balls weigh 1,417.4 grams

Then 1 ball weighs 1,417.4 grams/10 = 141.74

To the nearest tenth = 141.7

To the nearest gram= 142

If someone asks me the weight of one ball I will give the answer as 141.7 because it contains exactly the same number of decimal points as we have in the question.

Answers

Answer:

Step-by-step explanation:f(h(x))= 2x -21

f(x)= x^3 - 6

h(x)=\sqrt[3]{2x-15}

WE need to find f(h(x)), use composition of functions

Plug in h(x)

f(h(x))=f(\sqrt[3]{2x-15})

Now we plug in f(x) in f(x)

f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6

cube and cube root will get cancelled

f(h(x))= 2x-15 -6= 2 x-21

Which is closest to the length of diagonal
AC?

Answers

Answer:

A. 8 units

Step-by-step explanation:

Coordinates of A = (-2, -2)

Coordinates of C = (5, 2)

Use distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex] to calculate the length of diagonal [tex] \overline{AC} [/tex].

Let,

[tex] A(-2, -2) = (x_1, y_1) [/tex]

[tex] C(5, 2) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(5 -(-2))^2 + (2 -(-2))^2} [/tex]

[tex] d = \sqrt{(7)^2 + (4)^2} [/tex]

[tex] d = \sqrt{49 + 16} = \sqrt{65} [/tex]

[tex] d = 8.1 [/tex] (nearest tenth)

Therefore, the closest to the length of diagonal [tex] \overline{AC} = 8 units [/tex]

Find V. 10 points plz.

Answers

Answer:

v = 60 yards

Step-by-step explanation:

In the similar triangles, their corresponding sides are proportional which means they have equal ratios

In triangles IHG and FHJ

∵ Δ IHG ≈ FHJ

∵ Side IH is corresponding to side FH

∵ Side HG is corresponding to side HJ

∵ Side IG is corresponding to side FJ

→ Their ratios are equal

∴ [tex]\frac{IH}{FH}[/tex] = [tex]\frac{HG}{HJ}[/tex] = [tex]\frac{IG}{FJ}[/tex]

∵ IH = 54 yards and FH = 72 yards

∵ IG = v and FJ = 80 yards

→ Substitute them in the first and last ratios above

∴ [tex]\frac{54}{72}[/tex] = [tex]\frac{v}{80}[/tex]

→ By using cross multiplication

∴ v × 72 = 80 × 54

∴ 72v = 4320

→ Divide both sides by 72

∴ v = 60 yards

Answers

Answer:

The answer is 15.9 centimeters. If you work backward with the formula 2pir = circumphrence, you get diameter *pi = 50. To find diameter, you divide 50 by pi and the answer is 15.9 centimeters.

Step-by-step explanation:

The diameter to the nearest tenth of a centimeter is mathematically given as

31.8cm, option D

What is the diameter?

Question Parameters:

Circle Q has a circumference of approximately 50 centimeters.

Generally, the equation for the circumference   is mathematically given as

C=2\pir

Therefore

r=C/ \pi

r=50/3.14

r=15.9cm

Therefore,

d=2r

d=2*15.9

d=31.847

In conclusion, the diameter to the nearest tenth of a centimeter. is

31.8cm
