Answer:

100 inches (using the given data)

98.43 (using exact numbers)

Step-by-step explanation:

1 inch = 2.54 centimeters

20 inches = 50.8 centimeters, but for the purpose of answering this question we will assume that 20 inches = 0.5 meters (instead of 0.58).

we must solve the following equation:

20 inches / 0.5 meters = X inches / 2.5 meters

(2.5  meters x 20 inches) / 0.5 meters = X inches

20 inches x 5 = X inches

100 inches = X inches

if we do the exact calculation, 2.5 meters in inches = 250 centimeters / 2.54 centimeters per inch = 98.43 inches

Answer:

Yes, he has enough money to get his things.

Step-by-step explanation:

3 (the amount of grass seed bags he's buying)  x 23 (how many dollars it costs) = 69

3 (the amount of flower pots he's buying) x 15 (how many dollars it costs) = 45

69 + 45 = 114

He will have $6 left over his purchases.

Answer:

1/4

Step-by-step explanation:

7 divided by 24 = 4 so it gets reduced to 1 and then 1/4

The solution is: 1/4  is the simplified form of the fraction 7/28.

Here, we have,

given that,

the fraction is: 7/28

now, we divide each fraction numerator and denominator by a common divisor of them,

here, we know that,

7 * 1 = 7

7*4 = 28

so, the gcf of 7 and 28 = 7

we divide each fraction numerator and denominator by a common divisor 7,

we will get:

7/28 = 1/4

7 divided by 28 = 4 so it gets reduced to 1 and then 1/4.

Hence, The solution is: 1/4  is the simplified form of the fraction 7/28.

Answer:

Step-by-step explanation:

60 average speed

The delivery must be completed by Allan before he needs to stop, thus his average pace must be at least 60 mph.

It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

If Allan has to make a delivery that is 1200 miles away and can only drive for 20 hours without taking a break,

we need to find his average speed to see if he can make the delivery before the 20-hour mark.

We can use the formula:

average speed = total distance / total time

We know the total distance is 1200 miles.

To find the total time, we need to know Allan's maximum driving time before taking a break. Let's assume that Allan will take a break after driving for 20 hours.

So, Allan's total time available to make the delivery is 20 hours.

Therefore,

average speed = total distance / total time

average speed = 1200 miles / 20 hours

average speed = 60 miles per hour

Allan's average speed must be at least 60 miles per hour to make the delivery before he has to take a break.

Answer:

x = 22°

Step-by-step explanation:

The angles of a triangle add to 180°, so:

69 + (3x - 4) + (3x - 17) = 180

(3x - 4) + (3x - 17) = 111

6x - 21 = 111

6x = 132

x = 22

Answer:

22

Step-by-step explanation:

(3x - 4)° + (3x - 17)° + 69° = 180°

6x - 21 + 69 = 180

6x + 48 = 180 ⇒ x = 22

Answer:

1

Step-by-step explanation:

To evaluate, substitute x = - [tex]\frac{2}{3}[/tex] into f(x), that is

f(- [tex]\frac{2}{3}[/tex] )

= 3(- [tex]\frac{2}{3}[/tex] )² + 2(- [tex]\frac{2}{3}[/tex] ) + 1

= 3([tex]\frac{4}{9}[/tex] ) - [tex]\frac{4}{3}[/tex] + 1

= [tex]\frac{4}{3}[/tex] - [tex]\frac{4}{3}[/tex] + 1

= 0 + 1

= 1

Answer:

1

Step-by-step explanation:

f(x) = 3x² + 2x + 1

f(-2/3) = 3x² + 2x +1

f(-2/3) = 3(-2/3)² + 2(-2/3) + 1          

Substitute the value in for all the x's

f(-2/3) = 3(4/9) + 2(-2/3) + 1

f(-2/3) = 12/9 + (-4/3) + 1

f(-2/3) = 4/3 + (-4/3) + 1                

Subtracting 4/3 by (-4/3) gets you 0 so I didn't write it down.

f(-2/3) = 1

So, the answer I got is 1

Answer:

9a+9b

Step-by-step explanation:

Add b to a and multiply 9 by the result without simplifying any part of the expression.

Not simplifying an expression in algebra means not organizing or grouping like terms in the algebraic expression in such a way as to make it more understandable. It is not required in this case. Hence,

We add b to a

=a+b

We multiply 9 by the result

=9 * a+b

=9(a+b)

= 9a+9b

Answer:

Step-by-step explanation:

Given the the height covered by the ball modeled by the equation

y= -4.9x²+12

Since we are not told what to find, we can as well find the time taken by the ball to reach the ground.

The ball hits the ground when y = 0. Substitute y = 0 into the equation and calculate x;

y= -4.9x²+12

0 = -4.9x²+12

Subtract 12 from both sides

0-12 = -4.9x²+12-12

-12 = 4.9x²

x² = -12/4.9

x² = 2.448

x = √2.448

x = 1.57s

Hence we can say that the ball hits the ground after 1.57s.
