Answer:
Time taken by the object = 14 minutes
Step-by-step explanation:
Speed of an object = [tex]9\frac{4}{5}[/tex] miles per hour ≈ 9.8 miles per hour
Distance covered by the object = [tex]2\frac{1}{5}[/tex] miles ≈ 2.2 miles
Formula to calculate the distance in the time 't' is,
Time taken by the object = [tex]\frac{\text{Distance traveled}}{\text{Speed of the object}}[/tex]
= [tex]\frac{2.2}{9.8}[/tex]
= 0.2245 hours
= 13.47 minutes
≈ 14 minutes
Therefore, distance traveled by the object to cover 2.2 miles = 14 minutes.

A restaurant needs to plan seating for a party of 150 people. Large tables seat 10 people and small tables
seat 6. Let x represent the number of large tables and y represent the number of small tables. The
expression 10A +6B, which represents the total number of people you can seat using a large tables and
B small tables, is called a linear combination. For instance, 150 people could be seated using 3 large
tables and 20 small tables. Use that expression to enter an equation in standard form that models all the
different combinations of tables the restaurant could use. Then identify at least one possible combination
of tables other than (3, 20).
The equation is

What is the first step of the following division problem?
(8x3 – x2 + 6x + 7) ÷ (2x – 1)
Divide 8x3 by 2x.
Divide 2x by 8x3.
Divide 6x by 2x.
Divide 2x by 6x.
Answer:
Divide 8x^3 by 2x
Step-by-step explanation:
Here, we want to identify the first step to take in the polynomial division.
When working with a polynomial division, what to do is to divide the first term of the dividend by the first term of the divisor ( the divisor is arranged in descending powers of x)
The number we want to divide is the dividend, while the number we are using to divide is the divisor.
In this case, the first term of the dividend is 8x^3 while that of the divisor is 2x
The first step of the following division problem is to divide 8x³ by 2x
How to divide polynomialsGiven:
(8x³ – x2 + 6x + 7) ÷ (2x – 1)
(8x³ – x2 + 6x + 7) is the divided
(2x – 1) is the divisor
Dividend is number or expression that is to be divided by anotherDivisor is the number which is used to divide another.The first step in the be division of polynomial is to divide the first term of the bc dividend by the first term of the divisor.

Write 6.384 to 1 decimal place
Answer:
6.384 rounded to one decimal place is 6.4
Step-by-step explanation:
The number rounded to one decimal place is 6.4.
What is rounding off a number?To change a number into an approximation having fewer significant digits.
Given that, 6.384 to 1 decimal place,
Rounding 6.384 to one decimal place would be the same as rounding it to the nearest tenth.
The tenth in this number is 3. To round a number up, look at the number to the right of it - if the number is 5 or greater, then you increase the value of the number you're rounding by 1. If the number to the right of it is 4 or less, then the value of the number you're rounding stays the same.
In this case, the number we're rounding is 3 and the number to the right of it is 8. Since 8 is greater than 5, we have to increase the value of 3 by 1, which means that the number in the tenths position is now 4.
Hence, The number rounded to one decimal place is 6.4.

Please help. What is the slope for #2?
Answer: -4
Step-by-step explanation:
To find the slope, you want to use the slope formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You can use any two points to solve. Let's use (-2,3) and (-1,-1).
[tex]m=\frac{-1-3}{-1-(-2)} =\frac{-4}{1} =-4[/tex]
Another way to tell is by looking at the arrows with a -4 written next to it. That also tells you what the slope is.

A clothing store features Shirts and Pants in the ratio of 3:6. There are 42 more Shirts than pairs of pants. How many articles of clothing are in the store?
Answer:
126
Step-by-step explanation:
The ratio of shirts to pants = 3:6. Which also equals 1:2.
Let the pairs of pants = t
Since there are 42 more shirts than pair of pants, shirts = t + 42
Number of pairs of pants is t.
Number of shirts = (t + 42)
The number of the pairs of pants is 42.
The number of shirts is 84.
Total number of clothings is 126.

Answer:
5. x = 13
6. x = 11; y = 3
Step-by-step explanation:
5. (9x + 2)° = 119° (alternate interior angles are congruent)
[tex] 9x + 2 = 119 [/tex]
Subtract 2 from each side
[tex] 9x + 2 - 2 = 119 - 2 [/tex]
[tex] 9x = 117 [/tex]
Divide both sides by 9
[tex] \frac{9x}{9} = \frac{117}{9} [/tex]
[tex] x = 13 [/tex]
6. (9x + 25)° = (13x - 19)° (corresponding angles are congruent)
[tex] 9x + 25 = 13x - 19 [/tex]
Collect like terms
[tex] 9x - 13x = - 25 - 19 [/tex]
[tex] -4x = -44 [/tex]
Divide both sides by -4
[tex] \frac{-4x}{-4} = \frac{-44}{-4} [/tex]
[tex] x = 11 [/tex]
(13x - 19)° + (17y + 5)° = 180° (linear pair)
[tex] 13x - 19 + 17y + 5 = 180 [/tex]
Plug in the value of x and solve for y
[tex] 13(11) - 19 + 17y + 5 = 180 [/tex]
[tex] 143 - 19 + 17y + 5 = 180 [/tex]
Collect like terms
[tex] 129 + 17y = 180 [/tex]
Subtract 129 from both sides
[tex] 129 + 17y - 129 = 180 - 129 [/tex]
[tex] 17y = 51 [/tex]
Divide both sides by 17
[tex] \frac{17y}{17} = \frac{51}{17} [/tex]
[tex] y = 3 [/tex]
