Which expression is equivalent to the phrase shown below?
The quotient of the sum of 2t and 2, and twice the cube of s
A. 2t +23s2 C. 2t+23s2
B. 2t +22s3 D. 2t+22s3
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

Step-by-step explanation:
This probability is greater than the probability of flipping exactly two tails, which is .
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:
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.

Mr. Painter has moved into a new house. He wants to install carpet in the playroom. The floor is 15ft long and 13 feet wide. One roll of carpet covers 55 square feet. How many rolls of carpet does he need to buy?
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 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
Calculate the side lengths a and b to two decimal places
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

what two numbers multiply to -96 and add to -4
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
