Use the figure below to answer the following question. Which of the following angles is NOT supplementary and adjacent to 1) 2) 3)All answers are supplementary and adjacent to 4)

===============================================

Explanation:

If we replace x with 0, then we get...

f(x) = 3x^2-8x+2

f(0) = 3(0)^2 - 8(0) + 2

f(0) = 3(0) - 8(0) + 2

f(0) = 0 - 0 + 2

f(0) = 2

Showing that the input x = 0 leads to the output y = f(x) = 2

The answer is between choice A and choice D because of this. Something like choice B is eliminated because this table shows x = 0 leading to y = -3 which is not correct.

-----------

Let's plug in x = 1

f(x) = 3x^2-8x+2

f(1) = 3(1)^2 - 8(1) + 2

f(1) = 3(1) - 8(1) + 2

f(1) = 3 - 8 + 2

f(1) = -5 + 2

f(1) = -3

So x = 1 leads to y = -3. We can rule out choice D and confirm it is choice A.

We don't need to try other x values since we have the answer, but I recommend practicing with other x values to help confirm that the first table is the answer.

Answer:

<MON = 57°

Step-by-step explanation:

they are complementary angles so they add up to 90°

3x - 15 + 5x - 23 = 90

8x - 38 = 90

8x = 128

x = 16

5(16) - 23 = 57

Answer :

0.53

Step-by-step explanation:

Given the following :

Probability of female = probability of success on a single trial = 0.51

Number of babies = 80

Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)

The problem can be solved using the binomial probability function :

P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]

In other to save computation time, we can use the binomial probability calculator

Hence ; P(X > 40) = 0.527 = 0.53

Answer:

15 inches

Step-by-step explanation:

Hello!

To find the perimeter of a rectangle we have to add all the sides

l + l + w + w = p

We know the length is 6 inches more than the width

l = w + 6

We can put w + 6 for l

w + 6 + w + 6 + w + w = p

We can simplify this

4w + 12 = p

The perimeter is no more than 48

4w + 12 = 48

Subtract 12 from both sides

4w = 36

Divide both sides by 4

w = 9

Now we can put 9 in for w in the equation to find the length

l = 9 + 6

l = 15

The answer is 15 inches

Answer:

$8.40

Step-by-step explanation:

Price in England = 1.4 pounds per Litre

Current exchange rate : 1 pound = 1.65 dollars

1 Litre = 0.26 gallons

If 1 Litre = 0.26 gallons

1 gallon = (1 / 0.26) litres = 3.8461538 litres

Therefore, cost per gallon in England = (1.4 × 3.8461538)

= 5.3846153 pounds

Then ;

If 1 pound = 1.56 dollars

Then cost per gallon in dollars equals

5.3846153 * 1.56 = 8.399999868 dollars

4) -17n - 80

5) -160n

Can't factor

Answer:

B. -72n+60

Step-by-step explanation:

We are given the expression:

-8 (9n-10) -20

We want to simplify the expression. First, distribute the -8.

Multiply each term inside the parentheses by -8.

(-8 * 9n) + (-8*-10) -20

-72n + (-8 * -10) -20

-72n + 80 -20

Next, combine like terms. Currently, we have two constants (terms without variables) that can be combined.

Subtract 20 from 80.

-72n + (80-20)

-72n + 60

The expression: -8(9n-10)-20, simplified is -72n+60. Therefore, the correct answer is B. -72n+60

Answer:

85° (C).

Step-by-step explanation:

35° should go over to the other side of the line:

180 - 35 = 145°

Find angle 1:

145 + 130 + angle 1 = 360°

360° = 275° + angle 1

angle 1 = 360 - 275

angle 1 = 85°

85° which is C is the answer.

Answer:

Your correct answer is option C. 85 degrees.

Step-by-step explanation:

35 degrees goes over to the other side of the line:

180 - 35 = 145°

All you need to do is find angle 1.

145 + 130 + angle 1 = 360 degrees

360 degrees = 275 degrees + angle 1

angle 1 = 360 - 275

angle 1 = 85 degrees.

Therefore, option C. is the correct answer.

The total surface area of the cuboid is km². Therefore, option A is the correct answer.

The given dimensions are length=19 km, width=18 km and height=18 km.

We need to find the total surface area of the given cuboid.

Total surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, TSA=2lw+2lh+2hw, to find the surface area.

Now, TSA = 2(18)(18) + 2(18)(19) + 2(19)(18)

TSA = 648 + 684 + 684=2016 km²

The total surface area of the cuboid is km². Therefore, option A is the correct answer.

Answer:

7,234.56 cm^2

Step-by-step explanation:

We want to find the volume of the beach ball. The beach ball is in the shape of a sphere. The formula for the volume of a sphere is :

[tex]V=\frac{4}{3} \pi r^3[/tex]

We know the width, or diameter of the sphere is 24 cm. We need to find the radius. The radius is half the diameter.

r= d/2

r= 24 cm/2

r= 12 cm

The radius is 12 cm, and we can substitute it into the formula.

[tex]V=\frac{4}{3} \pi (12 cm) ^3[/tex]

First, evaluate the exponent.

(12 cm)³= 12 cm * 12cm * 12 cm= 144 cm² * 12 cm = 1728 cm³

[tex]V=\frac{4}{3} \pi * 1728 cm^3[/tex]

Substitute 3.14 in for pi.

[tex]V=\frac{4}{3} * 3.14 * 1728 cm^3[/tex]

Multiply all three numbers together.

[tex]V= 4.18666666 * 1728 cm^3[/tex]

[tex]V= 7234.55999 cm^3[/tex]

Round to the nearest hundredth. The 9 in the thousandth place tells us to round the 5 to a 6  in the hundredth place.

[tex]V= 7234.56 cm^3[/tex]

Fiona is going to jog once around the block she lives on. The block is rectangular, and it is 180 yards long and 200 feet wide. How far will Fiona jog (in feet)?

Answer:

Fiona will jog 1480 feet  once around the block she lives on.

Step-by-step explanation:

From the information given:

Length of the rectangular  block = 180 yards

Breadth of the rectangular block = 200 feet

The block have a rectangular shape and we are to determine how far will Fiona jog (in feet).

Converting yards to feet

1 yard = 3 feet

∴

180 yards = (180 × 3) feet

= 540 feet

Calculating the perimeter of the rectangle will determine how far Fiona will jog.

Perimeter of a rectangular block = 2 (length + breadth)

Perimeter of a rectangular block = 2(540 + 200) feet

Perimeter of a rectangular block = 2(740) feet

Perimeter of a rectangular block = 1480 feet

∴

Fiona will jog 1480 feet  once around the block she lives on.

[tex] \boxed{ \bold{ \boxed{ \sf {11.11\%}}}}[/tex]

Step-by-step explanation:

Given,

Cost price of three thermos flask = 1080

Selling price of each thermos flask = 400

Finding the selling price of three thermos flask

Since, the cost of 3 thermos flask is more than that of 1 thermos flask. So, the cost of 1 thermos flask is multiplied by 3 ( i.e 400 × 3 = 1200 )

Here, the selling price is greater than cost price.

So, there is profit.

And we know that,

[tex] \sf{profit = sp \: - \: cp}[/tex]

⇒[tex] \sf{1200 - 1080}[/tex]

⇒[tex] \sf{120}[/tex]

Answer:

the answer is three.

Step-by-step explanation:

first, simplify the exponent, which would be 36, then solve the 3+9, which is 12, then that leaves you with 36/12, and 12 goes into 36 3 times, so three is your answer

Answer:

The answer is 3

Step-by-step explanation:

To evaluate, we must do the order of operations. PEMDAS:

P=Parenthesis

E=Exponents and Radicals

M=Multiply

D=Divide

A=Add

S=Subtract

Because 6^2 ÷ (3 + 9), we must do the parenthesis which is add then simplify the exponent and lastly divide. So the equation will be:

6^2 ÷ (3 + 9)

= 6^2 ÷ 12

= 36 ÷ 12

= 3

Of the 30 girls who tried out for the basketball team at Prescott Junior High, 12 were selected. In this scenario the ratio will be:

= 12/30

= 2/5

= 2:5

Of the 40 boys who tried out, 16 were selected. In this scenario, the ratio will be:

= 16/40

= 2/5

= 2:5

The ratio for both are thesame as we got 2:5 for both.
