PLEASE HELP I HAVE TEST!! Find the measure of the arc or angle indicated

Answer:

6)31.25

7)622.92

8)16.666... or 16 2/3 or 50/3

9) 72

Step-by-step explanation:

Answer:

m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°

m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 104°

Step-by-step explanation:

Vertical angles are congruent.  When lines are parallel, corresponding angles are congruent.

m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°

m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 180 - 76° = 104°

Answer:

Step-by-step explanation:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

Answer:

9 x 7 = 63 <---- Parallelogram

10 x 6.8 = 68, 68 divided by 2 = 34 <------- Triangle

13 + 15 = 28, 28 x 6 = 168, 168 divided by 2 = 84 <------- Trapezoid

The trapezoid has the greatest area.

Formula of trapezoid:

B1(base 1) + B2(base 2) x H (height) x 1/2 (basically dividing by 2)

Formula of triangle:

B(base) x H(height) x 1/2 (basically dividing by 2)

Formula of Parallelogram:

B(base) x H(height)

Answer: D=16

Add 4 to both sides

D=16

Answer:

Answer: 16

Step-by-step explanation:

Do 12 -(-4 to get D

12 -(-4 = 16

Answer:

1500 grams of grain

Step-by-step explanation:

How many grams of grain will there be in 2.4 kg of shelled hazelnuts?

Step 1

Convert kg to g

1 kg = 1000g

2.4 g = x

Cross Multiply

x = 2.4 × 1000g = 2400g

Step 2

An 800 gram sample of shelled hazelnuts has 500 grams of grain.

Hence,

800g hazelnuts = 500 gram of grain

2400g hazelnuts = x

Cross Multiply

800x = 2400g × 500g

x = 2400g × 500g/800

x = 1500 grams of grain

Answer:

[tex]9450 {m}^{3}[/tex]

Step-by-step explanation:

Given ,

Length of the tank = 27m

Width of the tank = 35m

Depth of the tank = 10m

Therefore,

Volume of the tank = Length × Width × Depth

= 27m × 35m × 10m

[tex] = 9450 {m}^{3} (ans)[/tex]

Answer:

9450

Step-by-step explanation:

volume = length x width x height=27 x 35 x 10

Answer:

The number of new trailer homes that were added two years ago is 10

Step-by-step explanation:

Given that

Twenty years ago there are 20 trailer homes having an average age of 18 years

Today, the average of the age is 14 years

We need to find out the number of new trailer homes that would be added two years ago

Since as of now 20 trailer homes would be an average of 20 years and we assume the new trailers be n that are 2 years old

So

20 +  n

And, the sum of their ages i.e. (20) ( 20)  + 2n

Now the following equation is used

[tex]\frac{400 + 2n}{20 + n} = 14[/tex]

400 + 2n = 14(20 + n)

400 + 2n = 280 + 14n

120 = 12n

n = 10

Hence, the number of new trailer homes that were added two years ago is 10

Answer:

x = 29.5

y = 48.16

z = 34.05

Step-by-step explanation:

Sorry if the explanation is messy

answer

x=29.44

y=48.08

z=68

Step-by-step explanation:

opp/adj = tan(30)

17/x = tan(30)

x = 29.44

hyp^2 = x^2+y^2

hyp^2 = (29.44)^2 + (17)^2

hyp^2 = 867 + 289

hyp = 34

opp/hyp = Sin(45)

34/y = Sin(45)

y = 48.08

adj/hyp = Cos(45)

z/(48.08) = Cos(45)

z = 68

Step-by-step explanation:

im not sure if this is what ur asking for??

Given:

[tex]P(A)=0.4, P(B)=0.7, P(A\text{ and }B)=0.3[/tex]

To find:

The value of [tex]P(A\text{ or }B)[/tex].

Solution:

We know that,

[tex]P(A\text{ and }B)=P(A\cap B)[/tex]

[tex]P(A\text{ or }B)=P(A\cup B)[/tex]

It means, we have [tex]P(A)=0.4, P(B)=0.7, P(A\cap B)=0.3[/tex] and we need to find the value of  [tex]P(A\cup B)[/tex].

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

[tex]P(A\cup B)=0.4+0.7-0.3[/tex]

[tex]P(A\cup B)=1.1-0.3[/tex]

[tex]P(A\cup B)=0.8[/tex]

Therefore, the value of [tex]P(A\text{ or }B)[/tex] is 0.8.

Q) [tex]\left(\frac{1}{3}+\frac{3}{4}\right)[/tex] ÷ [tex]\left(\frac{5}{6}\right)^{2}[/tex] =?

→ [tex]\left(\frac{1×4}{12}+\frac{3×3}{12}\right)[/tex] × [tex]\left(\frac{6}{5}\right)^{2}[/tex]

→ [tex]\left(\frac{4}{12}+\frac{9}{12}\right)[/tex] × [tex]\left(\frac{36}{25}\right)[/tex]

→ [tex]\frac{13}{12}[/tex] × [tex]\frac{36}{25}[/tex]

Answer:

  see attached

Step-by-step explanation:

The various forms of the expression use the relation ...

  -5 1/4 = -5 + -1/4 = -(6 -3/4) = -6 +3/4

Of course, the minus sign in a product can be moved around according to the associative and commutative properties of multiplication.

(8)(-5 1/4)

= (8)(-5 + -1/4)

= 8(-5) +8(-1/4)

= 8(-5) -8(1/4)

= 8(-6 +3/4)
