Step-by-step explanation:

Answer:

-12 and 8

Step-by-step explanation:

Answer:

8 and -12

Step-by-step explanation:

xy = -96

x+y = -4

x = -y-4 which is the same as

substitution method:

y(-y-4) = -96

-y² - 4y + 96 = 0

-(y² + 4y - 96) = 0

(y + 12)(y - 8) = 0

y = -12

y = 8

Answer:

£160

Step-by-step explanation:

£262 x (100% - 39%) = £159.82 ≈ £160

Answer:

159.82

Step-by-step explanation:

262-%

262-(39%-262)

61/100*262

we take hundred at the place of%

61*262/100

15982/100

159.82

therefore£160

Answer:

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

Answer:

The answer is the letter D

Step-by-step explanation:

The sum of 2t and 2 could be written as:

[tex]a=2t+2[/tex]

Now, the twice of the cube of s will be:

[tex]b=2s^{3}[/tex]

Finally, the quotient between a and b will be:

[tex]\frac{a}{b}=\frac{2t+2}{2s^{3}}[/tex]

Therefore the answer is the letter D

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

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

Step-by-step explanation:

25 / 10 = 2.5

15 / 2.5 = 6

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 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:

The two lines are neither parallel nor perpendicular

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope of the line and b is the y intercept of the line

Now, we express the two given equations in this form

We have this as;

7y = x + 5

y = 1/7(x) + 5/7

For the second equation, we have;

y = 7x - 4; this is already expressed

the slope of the first line is 1/7

the slope of the second line is 7

when two lines are parallel, their slopes are equal

when two lines are perpendicular, the product of their slopes is -1

As we can see, both cases does not occur in this system of equations

So, we can conclude that both lines are neither parallel nor perpendicular

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

Picture #2

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

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.
