Step-by-step explanation:

The y-intercept of a graph is the point where the graph touches the y-axis.

The best describes the y-intercept of the graph is (a) the initial water level of the river is 16 ft

From the attached graph, we observe that the graph crosses the y-axis at y = 16

This value represents the initial value of the graph.

In other words, the initial water level of the river

So, the y-intercept means that:

The initial water level of the river is 16 ft

Hence, the true statement is (a)

Kay ran a mile in12.79 minutes, and

Rosie ran a mile in 9.58 minutes

Required

The time difference between  Eric run and Rosie

Step two:

The difference is

10.84- 9.58=1.26  minutes

Answer:

Would be 75.36

Step-by-step explanation:

Formula: V = πr^2 h (replace pi with 3.14)

(r × r)

= 3.14 × r^2 × h

(r^2 × h = #)

= #π (# × π)

= V

Answered Form: V = π2^2 6

(2 × 2)

= 3.14 × 2^2 × 6

(4×6 = 24)

= 24π (24 × 3.14)

V = 75.36

Total product cost which helps to  make the decisions regarding the product pricing. Total cost of the product is calculated by the product of the number of units of the products and the cost per unit.

Half gallon of milk is $2.12

Doz of egg is $0.85

5 lb of flour is $1.95

5 lb of sugar is $2.05

3 lb of shortening is $3.35

To find the cost of the ingredients of 1 pt (2cup) milk, 4 eggs, 2 lb (4cup) flour, 1 lb (2cup) sugar and 1 lb shortening

1 gallon = 8pt, then half gallon is 4pt

4 pt of milk cost is $2.12

Then cost of 1 pt of milk cost, 2.12/4 = $0.53

Total cost of ingredients is $0.53+ $0.283+ $0.78+ $0.41+ $1.1167 = $3.1197

Total cost of ingredients to make cake is $3.12

Any fat that is solid at room temperature and used to create flaky pastry and other foods are known as shortening.

Long before the creation of contemporary, shelf-stable vegetable shortening, the concept of shortening may be traced back to at least the 18th century.

Lard was the main component used to shorten dough in past eras. It behaves as though it has short fibers, which is why it is termed shortening since it makes the finished dish crumbly.

Answer:

x=? y=?

Step-by-step explanation:

these two triangles are similar so since the bottom side was 8 and became 10 it added 2 so therefore if you add 2 to the 5 and 7 you get

5+2=7

7+2=9

The value of 'x' is 5/4 and the value of 'y' is 7/4 and this can be determined by using similar triangle properties.

Given :

Two triangles are given in the figure.

The following steps can be used in order to determine the value of 'x' and 'y':

Step 1 - According to the given figure, both the triangles are similar.

Step 2 - So, the value of 'x' and 'y' can be calculated as:

[tex]\dfrac{5}{5+x}=\dfrac{7}{7+y}=\dfrac{8}{10}[/tex]    --- (1)

Step 3 - Now, solve the above equation for 'x'.

[tex]\begin{aligned}\\{\dfrac{5}{5+x}&=\dfrac{8}{10}\\50&=40+8x\\x&=\dfrac{5}{4}\\\end{aligned}[/tex]

Step 4 - Now, solve the equation (1) for 'y'.

[tex]\begin{aligned}\\{\dfrac{7}{7+y}&=\dfrac{8}{10}\\70&=56+8y\\y&=\dfrac{7}{4}\\\end{aligned}[/tex]

The value of 'x' is 5/4 and the value of 'y' is 7/4.

Step-by-step explanation:

This is a systematic sample because we are told that the student surveyor interviews the first 30 people to leave his school buildings north exit. This implies that it was not randomly generated but chosen at an ordered form of interval which in this case it is the first 30 people. Thus, the population has been zeroed down to the first 30 people.

Answer:

n = 5

Step-by-step explanation:

Coordinate of P = (n,3)

R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)

Coordinate of Q = (n,-2)

Using distance formula,

Distance between P & Q =

[tex] \sqrt{ {( n - n}) ^{2} + {( 3- ( - 2) })^{2} } [/tex]

[tex] = > \sqrt{ {(3 + 2)}^{2} } = \sqrt{ {5}^{2} } = 5[/tex]

Distance between P & R =

[tex] \sqrt{ {(n - 0)}^{2} + {(3 - 3)}^{2} } [/tex]

[tex] = > \sqrt{ {n}^{2} } = n[/tex]

But in question it is given that distance between P & Q is equal to the distance between P & R. So,

Step-by-step explanation:

Given the greatest common divisor and the least common multiple, the least possible value of mn is 896

The given parameters are:

M and N are positive integers

Greatest common divisor =  8

Least common multiple = 112

As a general rule;

The product of the greatest common divisor and the least common multiple of numbers represent the product of the numbers

This means that

mn = Greatest common divisor * Least common multiple

So, we have

mn = 8 * 112

Evaluate

mn = 896

Hence, the least possible value of mn is 896

A dimension is a measurement that includes length, width, and height. When you discuss an object or location's dimensions, you're referring to its size and proportions.

Dimensions are just the different aspects of what we perceive to be reality.

We are acutely aware of the three dimensions that surround us on a daily basis: the length, width, and depth of all items in our universes, as well as the one dimension of time.

But here's the prospect that there are many more dimensions out there. According to string theory, one of the most influential physics theories of the last half-century, the universe has ten dimensions.
