Answer:

D. 2/3

If 2/6 equals 1/3, then 1/3 + 1/3 = 2/3.

Answer:

4/6

Step-by-step explanation:

Make 1/3 into 6 as its denominator.

1 x 2 = 2

3 x 2 = 6

Black beans fill up 2/6 of the bag.

Red beans fill up 2/6 of the bag.

Find out what is the fraction both bags fill up altogether.

2/6 + 2/6 = 4/6

Answer:

The probability of getting exactly two tails = 1/4

All the values greater than 1/4

or 3/4

Step-by-step explanation:

In a flip of a coin the probability of getting a tail is 1/2. If this is denoted by p =1/2 then q= 1-p= 1-1/2= 1/2

and if we have number of trials n=2

Then the binomial distribution can be applied.

(p+q)ⁿ =(p+q)² = 2c0p⁰q2 + 2c1p¹q¹ + 2c2p²q⁰

We wish to find probability of flipping exactly two coins  given by 2c2p²q⁰

= 2c2 (1/2)²(1/2)⁰

= 1/4

So the probability of getting exactly two tails = 1/4

The probability greater than 1/4 can be  all the values from 2/4, 3/4 ------1

or it can be found by

1- 1/4 = 3/4

as the total probability is always equal to 1

Answer:

Option (a) is correct.

a = 15.68 and  b = 19.58

Step-by-step explanation:

Given: A triangle with some given measurements.

We have to find the values of a and b.

For a triangle ABC , with side opposite to angle A is a , side opposite to angle B is b and side opposite to angle C is c,

Using Sine rule , we have,

For the given Δ ABC,

∠A = 50° , ∠B = 107°

AB = c = 8 , AC = b and BC = a

Using angle sum property of triangle,

Sum of angles of a triangle is always 180°

So ,  ∠A + ∠B +∠C = 180°

Solving for ∠C , we get,

∠C = 180° - 107° - 50°

∠C = 23°

Substitute in Sine rule  , we have,

Consider first and last  ratios, we have,

Solving for a, we have,

We get , a = 15.68

Consider last two ratios, we have,

and now solving for b ,

We get , b = 19.58

Thus, option (a) is correct.

a = 15.68 and  b = 19.58

Answer:

the volume of rectangular prism is 11 ft.

the volume of triangle prism is 7 ft.

Answer: There are 56 boys in the 10th grade

Step-by-step explanation:

Step 1

ratio of boys to girls in the 10th grade is 8 :13

Number of girls= 91

To find the number of boys, we first find the total number of boys and girls in the 10th grade

Step 2

Now the total ratio= 8 +13=21

Number of girls = ratio of girls/ total ratio  x  Total number of students

91=13/ 21  x  Total number of students

Total number of students =21 x 91 / 13  =147

Step 3

Therefore Number of boys =ratio of boys/ total ratio  x  Total number of student

8/21 x 147=56

here's the solution,

volume of cone :

[tex]v = \dfrac{1}{3} \pi {r}^{2} h[/tex]

Answer:

Picture #1

Triangles ΔJKL and ΔXYZ have:

∠X is corresponding to ∠J, since they are different (90° vs 38°), the triangles can't be similar

Perimeter is the sum of the sides each has same ratio.

The ratio of the perimeters will be same as the ratio of each corresponding pair.

Correct choice is C. 3:5

Total number of apples = 200

Apples you gave to your friend = 60

Apples left = ?

Apples left

[tex] = 200- 60 \\ = 140[/tex]

✏ You will have 140 apples left.

ʰᵒᵖᵉ ⁱᵗ ʰᵉˡᵖˢ

Answer: 140 apples

Step-by-step explanation:

If you start off with 200 apples, but then give 60 of them, you would subtract 60 from 200.

200 - 60 = 140

You would be left with 140 apples.

Answer:

(x+3, y+2)

Step-by-step explanation:

choose a letter: let's use points A and A'

A: (-3, 3)

A': (0, 5)

the rule would be (x+3, y+2) because (-3+3, 3+2) = (0,5)

Try it on another point:

B: (-4, 0)

B': (-4+3, 0+2) = (-1, 2) which checks out!

Answer:

55.4 ft/s

Step-by-step explanation:

The easiest way to do this is to plug it into a calculator. The problem tells us that x is an object that has fallen a certain amount of feet. Then, the problem gives us that the object has fallen 48 feet. We can now plug 48 in for x and you get 55.4

Answer:

7 Gallons and 6 pints !

Step-by-step explanation:

62 ÷ 8 = 7.75 gal.

0.75 gallons is 6 pints.

So, Its 7 gallons and 6 pints

Answer:

7 gallons 4 pints

Step-by-step explanation:

2 pints = 1 quart and 4 quarts = 1 gallon, and so 8 pints = 1 gallon

Write and solve an equation of proportions to answer this question:

 8 pints         1 gal

--------------- = -----------

62 pints            x

Cross-multiplying, we get 8x = 62, or 7 1/2.

That's 7 gallons 4 pints.

Answer:

A. 47 reams

Step-by-step explanation:

Total copies counted by the copier = 23,500 copies

Number of sheets in a ream = 500 sheets

How many reams of paper were used?

Number of reams of paper used = Total copies counted by the copier / Number of sheets in a ream

= 23,500 / 500

= 47

Number of reams of paper used = 47 reams

Answer: She had already surprised everyone by becoming the first black woman in Congress after an upset victory in 1968. Then Shirley Chisholm signed up for work as a census taker in Brooklyn, where she represented a range of struggling neighborhoods.

It was a thankless task; many of the “enumerators” for the 1970 census quit because so many poor black and Hispanic residents refused to answer questions or even open the door.

Their distrust in government ran deep, The Times reported, with some fearing that giving up their personal information would lead to genocide.

Ms. Chisholm, a daughter of immigrants from Barbados who studied American history with the zeal of a woman determined to shape it, understood such sentiments. She also embodied what was needed to bring those New Yorkers into the fold. It wasn’t pontificating. It wasn’t condescending, or scolding; it required the same charm and resolve she showed first as an educator, then as a politician.

“I do not see myself as a lawmaker, an innovator in the field of legislation,” she wrote in her 1970 autobiography, “Unbought and Unbossed.” “America has the laws and the material resources it takes to insure justice for all its people. What it lacks is the heart, the humanity, the Christian love that it would take.”

Answer:

Number of rolls to be purchased = 4

Step-by-step explanation:

Mr. Painter wants to install a carpet in the playroom having dimensions as 15 ft by 13 ft.

Area of the playroom's floor = Length × Width

                                               = 15 × 13

                                               = 195 square feet

∵  55 square feet of the floor is covered by number of rolls = 1

∴ 1 square feet area will require the number of rolls = [tex]\frac{1}{55}[/tex]

∴ 195 square feet will require the number of rolls = [tex]\frac{195}{55}[/tex]

                                                                                  = 3.55

Therefore, number of rolls to be purchased = 4
