A bag of flour weighs 15 kg. A baker has one bag of flour. She uses 1.065 kg every day. How much flour does she use in 8 days? How much flour is left over after 8 days?

Answers

Answer:

She uses 8.52 kgs of flour in 8 days

There are 6.48 kgs of flour left over after 8 days.

Step-by-step explanation:

First, you need to multiply 1.065 by 8 to get how much flour she uses in 8 days.

1.065 times 8 is 8.52. She uses 8.52 kgs of flour in 8 days.

Now, to get how much flour is left over after 8 days, you need to subtract 8.52 from 15 kgs.

15 - 8.52 = 6.48 kgs.

The height of a falling pinecone can be represented by y = -16° +64 where t is the time in seconds
and y is the height of the pinecone in feet. Write and solve an equation to find the number of seconds it
will take for the pinecone to reach the ground.
A. 4 seconds
B. 6 seconds
C. 2 seconds
D. 1.5 seconds

Answers

Answer:

4 Seconds

Step-by-step explanation:

Let's say the height of the ground is set at y = 0.

Then, since 16 times 4 is 64, we substitute 4 for x.

But wait! x is being squared!

So we need to find out what squared is 4. It's 2.

So, with x being equal to two, y is equal to 0.

But what is the number of seconds? We actually got it first.

That means that the answer is 4.

The pinecone takes 4 seconds to reach the ground.

Answers

Tbe question doesn't state the number of days he walked to school out of 20 school days in the

Month of February.

Answer:

Kindly check explanation

Step-by-step explanation:

To. Obtain the fractional representayion for the number of days he walked to school ;

Let the number of days he walked to school = 10 (this is an hypothesized value)

Number of school days in February = 20

Fraction = 10 /20 = 0.5

The percentage of times walked to school : multiply the fraction obtained above by 100%

0.5 * 100% = 50%

Just put the desired value and proceed uSing the steps described above.

Consider function g.
g(x) = 5/x - 1 + 2

What is the average rate of change of function g over the interval [-4, 3]?

A. 1/2
B. -1/2
C. -7/2
D. 2

Answers

Answer:

Step-by-step explanation: The answer is 1/2. This is on the Odyssey online Algebra 2 mastery test.

The average rate of change of function g over the interval [-4, 3] will be;

⇒ 1/2

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The function g is,

⇒ g (x) = 5 / (x - 1) + 2

And, The interval is,

⇒ [ - 4, 3 ]

Now,

We know that;

The average rate of change of function at interval [a, b] is,

⇒ f (b) - f (a) / (b - a)

So, The average rate of change of function g over the interval [-4, 3] is,

⇒ g (3) - g (- 4) / (3 - (- 4))

Here, The function g is,

⇒ g (x) = 5 / (x - 1) + 2

Put x = 3;

⇒ g (3) = 5 / (3 - 1) + 2

           = 5/2 + 2

           = 4.5

Put x = - 4;

⇒ g (-4) = 5 / (- 4 - 1) + 2

            = 5 / - 5 + 2

            = - 1 + 2

            = 1

So, WE get;

The average rate of change = (4.5 - 1) / 7

                                           = 3.5 / 7

                                           = 1/2

Step-by-step explanation:

One way to do this is to find the x- and y-intercepts and to plot these:

x-intercept:  Let y = 0:  5x = -2, or x = -2/5, so the x-intercept is (-2/5, 0).  Plot this point.

y -intercept:  Let x = 0:  y = -2, so the y-intercept is (0, -2).  Plot this point.

Finally, draw a line through these two points.

There are 42 more red marbles in a jar than there are white marbles. If there are 238 marbles in the jar, how many of them are red and how many are white?



Answers

Answer: red marbles = 140

White marbles = 98

Step-by-step explanation:

Let the number of white marbles be represented by x

Since there are 42 more red marbles in a jar than there are white marbles, red marbles will be: = x + 42

Since there are 238 marbles in the jar, this can be represented in an equation as:

x + x+42 = 238

2x + 42 = 238

2x = 238 - 42

2x = 196

x = 196/2

x = 98

White marbles = 98

Red marbles = x + 42

= 98 + 42

= 140
