2√6 + 4

Answer: A

Step-by-step explanation:

Answer:

Greatest common factor of 17

So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

- (m - 1 )( 7m + 17 )

Answer:

Matt used 65 carpet tiles.

Step-by-step explanation:

The rounded figure of the amount Alex paid at the groceries shop is $108.

The process of replacing a number by another number of approximately the same value but having fewer digits is called rounding a figure.

Given that, Alex paid 108.34 for groceries. We need to round it to the nearest dollar,

We know that,

If the first decimal digit is 5 or more, we increase the whole part by one unit. For example, $34.57 rounded to the nearest whole dollar is $35.

If the first decimal digit is less than 5, we leave the whole part as it is. For example, $45.19 rounded to the nearest dollar is $45.

Here, the first decimal point is less than 5, therefore, we will leave the whole part as it is.

Hence, the rounded figure of the amount Alex paid at the groceries shop is $108.

Answer:

y = 1/2 x+4

Step-by-step explanation:

Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.

The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].

I'll be plugging in (2,5) and (4,6) to calculate the slope.

m = (6-5)/(4-2) = 1/2

The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.

Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4

Answer:

£7.80

Step-by-step explanation:

Since you multiply 2 by 3 to get 6, we are going to multiply 2.6 by 3

2.6 x 3 = 7.8

Thus the cost of 6 litres of lemonade is £7.80

Answer:

15.5 quarts

Step-by-step explanation:

1.5 +8 + 4 + 2

there is need to convert the measures that are not in quarts to quarts

1 gallon  = 4 quarts  : 2 x 4 = 8 quarts

1 cup = 0.25 quarts : 0,25 x 8 = 2 quarts

1 pint = 0.5 quarts : 0.5 x 3 = 1.5 quarts

Total quarts = 1.5 +8 + 4 + 2 = 15.5 quarts

Answer:

R = 30

Step-by-step explanation:

Given y is directly proportional to R² then the equation relating them is

y = kR² ← k is the constant of proportion

To find k use the condition when R = 4, y = 24, then

24 = k × 4² = 16k ( divide both sides by 16 )

1.5 = k

y = 1.5R² ← equation of proportion

When y = 1350 , then

1350 = 1.5R² ( divide both sides by 1.5 )

900 = R² ( take the square root of both sides )

[tex]\sqrt{900}[/tex] = R , that is

R = 30

Answer:

85°

Step-by-step explanation:

there's 180° in a triangle

Step-by-step explanation:

x + 65° + 30° = 180° { being sum of angles of triangle }

x + 95° = 180°

x = 180° - 95°

x = 85°

Answer:

It takes 3.5 cups of pancake mix and 2.625 cups of water to make 21 pancakes.

Step-by-step explain

First divide each by 6 to figure out how much mix and water it takes to make one pancake

1/6 mix + .125 cups water = 1 pancake

Multiple each by 21 to know how much mix and water it takes to make 21 pancakes

3.5 mix + 2.625 water = 21 pancakes

Answer:

Step-by-step explanation:

Answer:

about 58 years 6 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7.25%/100 = 0.0725 per year,

then, solving our equation

t = 10600 / ( 2500 × 0.0725 ) = 58.4828

t = 58.4828 years

The time required to

accumulate simple interest of $ 10,600.00

from a principal of $ 2,500.00

at an interest rate of 7.25% per year

is 58.4828 years (about 58 years 6 months).

Answer:

5 years

Step-by-step explanation:

Find out how much you earn a year from interest and money.

Find 1%.

100% = 2500

1% = 2500 ÷ 100 = 25

7.25% = 25 x 7.25 = 181.25

2500 + 181.25 = 2681.25

Now divide how much you earn from money and interest from 13100.

13100 ÷ 2681.25 = 4.88

4.88 estimated to 5
