Answer:

9.14 servings

Step-by-step explanation:

The question is asking how many servings of cereal does the box contain, or in other words, how many groups of 56 grams can you make from 512 grams.

To find out how many groups of 56 you can make, you need to divide 512 by 56:

512 ÷ 56 = 9.14

Step-by-step explanation:

1) Combine Like Terms

-8w + 16x + 20w – 40x

= -24x + 12w

2) Apply the distributive property to simplify

the expression

8(12x – 20)

= 96x - 160

3) Add 7w – 12 and -15w + 60

= -8w + 48

The probability that you first choose a green marble and then a blue marble is, P(green then blue) = 1/5.

What is probability?

Simply put, probability measures how likely something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Given:

A bag contains 2 blue, 1 red, and 3 green marbles.

So, the total marbles are 2 + 1 + 3 = 6

The probability of selecting a green marble is:

P(Green) = 3/6

Now, there are 5 marbles left.

The probability of selecting a blue marble is:

P(Blue) = 2/5

The required probability is:

P = 3/6 * 2/5 = 6/30 = 1/5

Hence, the probability that you first choose a green marble and then a blue marble is, P(green then blue) = 1/5.

The required parameters of a smaller surface area and a smaller amount of metal per can are a radius of 3.05 cm and a height of 6.09 cm.

The measurement that indicates the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina. A three-dimensional shape's surface area is the sum of all of its faces. Finding the area of each face and adding them together gives us the surface area of a form.

Here,

V=πr²h

178=πr²h

πrh=178/r

S=2πr²+2πrh

S=2πr²+2*(178/r)

S=2πr²+356/r

S'=4πr-356/r²

S'=0

4πr=356/r²

r³=356/4π

r³=28.343

r=3.05 cm

h=178/πr²

h=178/(3.14*3.05*3.05)

h=178/29.23

Answer:220%

Step-by-step explanation:

Answer:

$150

Step-by-step explanation:

Let's call the cost price of the watch C. The salesperson sells the watch at 90% of the cost price, so they sell the watch for 0.9 * C dollars.

We know that 0.9 * C = 108 dollars, so C = 108 / 0.9 = <<108/0.9=120>>120 dollars.

The salesperson wants to make a profit of $30, so they need to sell the watch for 120 + 30 = <<120+30=150>>150 dollars.

There is an 8.1% probability that any given distance will exceed 212.50 cm.

A probability is a numerical representation of the likelihood or chance that a specific event will take place.

Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

I frequently remind kids that we can express probabilities as ratios, percentages, fractions, or decimals so they are aware of the variety of ways we express odds.

So, the probability that the individual distance is greater:

z = 212.50-200/8.9 = 1.4

Looking up 1.4 in the normal distribution table:

P(z>1.4) = 1 - 0.9192 = 0.0808

= 8.1%

Therefore, there is an 8.1% probability that any given distance will exceed 212.50 cm.

Answer:

y = - 3x - 28

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x + 12 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then

y = - 3x + c ← is the partial equation

to find c substitute (- 9, - 1 ) into the partial equation

- 1 = 27 + c ⇒ c = - 1 - 27 = - 28

y = - 3x - 28 ← equation of perpendicular line

Congruence is a property between two or more shapes that proves that they are equal in all respect. The required proof in the given question is shown below:

Two or more figures are said to be congruent if and only if they have equal length of sides, or measure of interior angles.

A triangle is a plane shape bounded by three straight sides, with three interior angles. The series properties can be used to classify the types of triangles with respect to their sides and angles. Some types of triangles are; equilateral, isosceles, right angled, acute angles scalene etc.

Answer:

Step-by-step explanation:

To find the unit cost per DVD, you need to calculate the total cost of producing 1 million DVDs and divide that by the number of DVDs produced.

First, you need to find the cost of producing 1 DVD. You can do this by dividing the cost of building the factory by the number of DVDs produced per dollar spent on the factory:

cost of 1 DVD = $80,000 / (20 DVDs/$3) = $1

Then, you can multiply this cost by the number of DVDs produced to find the total cost of producing 1 million DVDs:

total cost = (cost of 1 DVD) * (number of DVDs) = $1/DVD * 1,000,000 DVDs = $1,000,000

Finally, you can divide the total cost by the number of DVDs produced to find the unit cost per DVD:

unit cost per DVD = total cost / number of DVDs = $1,000,000 / 1,000,000 DVDs = $1/DVD.

So, the unit cost of producing 1 DVD is $1.

The measure of angle ∠C = 35°, 2x = 50° and x = 25°.

In Euclidean geometry, an angle is made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively.

Angles can be formed by two rays in the plane where they are placed.

Additionally, when two planes overlap, angles are created.

Dihedral angles are what they are called.

So, m∠ABC:

We know that ∠C in triangle ABC = 180 - 145 = 35°

Now, the measure of  m∠ABC:

95 + 35 + 2x = 180

130 + 2x = 180

2x = 180 - 130

2x = 50°

x = 50/2

x = 25°

Therefore, the measure of angle ∠C = 35°, 2x = 50° and x = 25°.

The required linear function to model the amount of money in Iri's account at any time t using the simple interest formula is 185 + 5.55t.

An expense associated with borrowing money or other assets is interest.

The principal is the amount borrowed, and the interest is calculated as a percentage of the principal for a specific period of time.

If someone borrowed $1,000 at 2% interest and accumulated $100 in interest, the interest for that year would be $22.

It's because interest is paid on a total of $1100, which includes the principal ($1000) and accrued interest ($100). 2% of $1100 is $22.

So, in this situation, the checking account offers simple interest at a rate of 3% annually. Her account has $185 in it.

The total balance of the account will always be:

= 185 + (PRT/100)

P = principal

R = rate

T = time

Then,

= 185 + [(185 × 3 × t)/100]

= 185 + 5.55t

185 + 5.55t is the function.

Therefore, the required linear function to model the amount of money in Iri's account at any time t using the interest formula is 185 + 5.55t.
