To multiply two or more fractions, multiply the denominators of both fractions together, and their numerators together.

1. (-3/4)(7/8)

Multiply the denominators of the fractions together, and also multiply their numerators:

= (-3 × 7) / (4 × 8)

= (-21) / (32)

(-3/4)(7/8) → -21/32

2. (2/3)(-4)(9)

Multiply the denominators of the fractions together, and also multiply their numerators:

= (2 × -4 × 9) / (3)

= -72/3 = -24

(2/3)(-4)(9) → -24

3. (5/16)(-2)(-4)(-4/5)

= (5 × -2 × -4 × -4) / (16 × 5)

= -160/80 = -2

(5/16)(-2)(-4)(-4/5) → -2

4. (2 3/5)(7/9)

= (13/5)(7/9)

= (13 × 7)/(5 × 9) = 91/45

The idea behind algebraic expressions is to represent numbers using letters or alphabets rather than giving their exact values. In algebraic basics, we learned how to express an unknown number using letters like x, y, and z. We will refer to these letters as variables from now on. An algebraic expression may have both constants and variables. Any amount that is added to a variable before it is multiplied by another is known as a coefficient.

This statement about distance is proved.

What is distance ?

It is length of space between two points.

Okay, so the first three components of this issue involve more physics and math. So, part A received the formula Ds = R. D. Data. We have to track down S. Therefore, we simply integrate both sides equally using R. D. Data. Our data are provided. Therefore, the upon integration over our data is just R 0 Santa plus 12 beta zeta squared for part B. We'll make sure S = V T. We combine these two by using the above equation as an equal. In order to allow it to reach its roots once positive, we can see that this is Justin's equation for data. The other negative, which is naturally a positive one because it has the proper physical meaning, would indicate that the rotation is occurring in the opposite direction.

Standard units, uh, are zero point 24/7 times, so switch to the nature radio's negative six setting. Additionally, we are given the time, which is 74 minutes, or 4440 seconds.

The rate of change of the divers elevation = 19.274

Given,

The depth to which the Scuba dove = -69 [tex]\frac{9}{10}[/tex] feet

The rate at which he dove = -21.5 feet per min.

The time which he spent at the elevation = 12.5min.

The elevation the diver then ascended to -38 [tex]\frac{9}{10}[/tex] feet

Thee total time for the dove = 19 [tex]\frac{1}{8}[/tex] minutes.

Therefore, the time [tex]t_{d}[/tex] with which the scuba diver descended to -69 [tex]\frac{9}{10}[/tex] feet

is given as follows:
[tex]t_{d} = \frac{Distance}{speed}[/tex] = [tex]= \frac{-69\frac{9}{10} }{-21.5}= \frac{-681}{-21.5}[/tex] = 3.167 minutes

The time [tex]t_{e}[/tex], it took the scuba diver to elevate to -38 [tex]\frac{9}{10}[/tex] feet is given as follows:

[tex]t_{e}[/tex] = 19 [tex]\frac{1}{8}[/tex]minutes - (3.167 + 10.5) minutes = 5.458 minutes

The rate of change of the divers elevation = (Final elevation - Initial elevation)/(Time taken).

∴ The rate of change of the divers elevation

= (-38 [tex]\frac{9}{10}[/tex] - (-69 [tex]\frac{9}{10}[/tex] )) / 5.458 min

=(37.1 - (-68.1))/ 5.458 min

Answer:

125 : 1

Step-by-step explanation:

given 2 similar objects with ratio of sides a : b , then

ratio of volumes = a³ : b³

here

ratio of pot A : pot B = 15 : 3 = 5 : 1

ratio of volumes = 5³ : 1³ = 125 : 1

If the radius to the inside of the shell is 4 millimeters and the radius to the outside of the shell is 4.3 millimeters. the volume of the shell is 19π mm³.

v = 4 / 3πr³

dv =4 / 3π (3r²) dr

Where:

r= radius = 4 cm

dr = 4.3 -4 = 0.3

Hence,

dv = 4 / 3π (16) 3/10

dv =4 / 3π(16) 0.3

dv = 19.2π mm³

dv = 19π mm³ (Approximately)

Therefore the volume of the shell is 19π mm³.

The solution of the equation is m = 6.

The variable to find is variable m.

The equation is as follows:

−3(m − 4) = − 6

Hence, let's open the bracket on the left side of the equation

−3(m − 4) = − 6

- 3m + 12 = -6

subtract 12 from both sides of the equation

- 3m + 12 = -6

- 3m + 12 - 12 = -6 - 12

- 3m = - 18

Mai's bike ride was 1.5 times the length of Noah's bike ride

Fractions: A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Distance travelled by Mai in miles = 6 3/4 miles

Distance of Mai in improper fraction = 27/4

Distance travelled by Noah in miles = 4 1/2

Distance of Noah in improper fraction = 9/2

Length of Noah's bike ride as compared to Mai's bike ride = (27/4)/(9/2)

From the given graph, we are expected to find the unit rate of ounces of water per cup of flour for the situation.

Now, to find the unit rate , all we need to do is to pick two coordinates on the line graph and find the slope. Thus;

Slope = (y2 - y1)/(x2 - x1)

Slope of graph = (12 - 9)/(4 - 3)

Answer:

x = 13

calculations in the pic hope it helps

Answer is 13

Step by step

1.4 + x / 6 = 2.4

We want to get rid of the 6 first

It is a divide so we want to do the inverse, which is multiply both sides by 6

1.4 + x * 6/ *6 = 2.4 * 6

Combine (the 6/6 becomes 1)

1.4 + x = 14.4

Now we want to isolate the x

Subtract 1.4 from both sides to solve for x

1.4 - 1.4 + x = 14.4 - 1.4

Combine

x = 13

Answer:

j = 1

Step-by-step explanation:

calculate the slope m between the 2 points and equate to - [tex]\frac{7}{10}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, j ) and (x₂, y₂ ) = (5, - 6 )

m = [tex]\frac{-6-j}{5-(-5)}[/tex] = [tex]\frac{-6-j}{5+5}[/tex] = [tex]\frac{-6-j}{10}[/tex]

then equating gives

[tex]\frac{-6-j}{10}[/tex] = - [tex]\frac{7}{10}[/tex] ( cross- multiply )

10(- 6 - j) = - 70 ( divide both sides by 10 )

- 6 - j = - 7 ( add 6 to both sides )

- j = - 1 ( multiply both sides by - 1 )

j = 1

Answer:

Step-by-step explanation:

Slope formula: m=[tex]\frac{rise}{run}[/tex] so m= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]y_1[/tex]=3

[tex]y_2[/tex]=-1

[tex]x_1[/tex]=0

Given picture is not a graph of inequality y < 6x + 1

In this question, we have been given a graph.

We need to determine whether the picture is a graph for the inequality y < 6x + 1 or not.

We know that the graph of equation y = 6x + 1 is a straight line and we represent a straight line graph by a solid line.

This graph represents a shaded region below dotted line. This means, this is the graph of inequality.

From this graph we can see that x-intercept of the equation is (2, 0) and y-intercept is (0, - 4)

If we find the x and y-intercept of y = 6x + 1 then it would be,

x - intercept = (-1/6 , 0)

y - intercept = (0, 1)

This means, given picture is not a graph of inequality y < 6x + 1

Answer: See attached and/or view below.

Step-by-step explanation:

      Since we are given the equation, we can plug the values into it and solve for the unknown. We will solve by isolating the variable and using reverse operations.

      x = 1, y = 34

2x + y = 36

2(1) + y = 36

2 + y = 36

y = 34

      x = -2, y = 40

2x + y = 36

2(-2) + y = 36

-4 + y = 36

y = 40

      y = 18, x = 9

2x + y = 36

2x + (18) = 36

2x = 18

x = 9

Answer:

x^2= 50 ------ (equation 1)

x^3= 37 ------- (equation 2)

dividing (equation 2) by (equation 1)

by using multiplication, we get that 28 BLT sandwiches can be made by Omar.

We are given that:

For every full head of lettuce used,

Number of tomatoes used = 5

Now, we will use multiplication.

2 full heads of lettuce used = 5 × 2 = 10 tomatoes used

Now, we also have:

2 tomatoes used = 1 1/20 pounds of bacon  used.

= 21/20 pounds of  bacon used.

1 tomato = (21 / 20) × (1 / 2) = 21 / 40 pounds bacon

10 tomatoes = (21 / 40) × 10 = 21 / 4 pounds bacon

Also,

3 / 4 pounds of bacon = 4 sandwiches

1 pound of bacon = 16 / 3 sandwiches.

21 / 4 pounds of bacon = (16 / 3) × (21 / 4) = 28 sandwiches

Therefore, by using multiplication, we get that 28 BLT sandwiches can be made by Omar.

By using a rotation rule, the image of point P = (- 4, 1) after rotating 180° counterclockwise using center (- 3, 0) is equal to point P'(x, y) = (- 2, 1).

In this problem we find the case of a point that must be rotated 180° counterclockwise (+ 180°) about the point (- 3, 0). Rotation is a kind of rigid transformation, that is, a kind of transformation applied on a point such that Euclidean distance is conserved. The rotation formula for a point P(x, y) = (x, y) around the center O(x, y) = (Ox, Oy) is introduced below:

P'(x, y) = (Ox + (x - Ox) · cos θ - (y - Oy) · sin θ, Oy + (x - Ox) · sin θ + (y - Oy) · cos θ)

Where θ is the angle of rotation.

If we know that O(x, y) = (- 3, 0), P(x, y) = (- 4, 1) and θ = 180°, then the coordinates of the image are:

P'(x, y) = (- 3 + [- 4 - (- 3)] · cos 180° - (1 - 0) · sin 180°, 0 + [- 4 - (- 3)] · sin 180° + (1 - 0) · cos 180°)

P'(x, y) = (- 3 - [- 4 - (- 3)], - 1)

P'(x, y) = (- 3 - (- 1), - 1)

P'(x, y) = (- 2, - 1)
