1.88 × 10² greater than 2.35 × 10⁻¹ by 800 times which is found by using division.

The two numbers given are:

1.88 times 10²

= 1.88 × 10²

And

2.35 times 10⁻¹

= 2.35 × 10⁻¹

We need to find that how much time is 1.88 × 10² greater than 2.35 × 10⁻¹.

We will use division for the same.

So, we get that:

= 1.88 × 10² / 2.35 × 10⁻¹

Using the rules of exponents and simplify the expression, we get that:

= 0.8 × 10 ²⁺¹

= 0.8 × 10³

= 0.8 × 1000

= 800

Therefore, we get that, 1.88 × 10² greater than 2.35 × 10⁻¹ by 800 times which is found by using division.

The height of the sand is changing when the height of the sand is 5 cm is 0.7848 in cm/sec

Volume is a measure of three-dimensional space that is occupied. It is frequently quantified numerically using SI-derived units (such as the cubic metre and litre) or various imperial units (such as the gallon, quart, cubic inch). The definition of length (cubed) is related to volume. The volume of a container is commonly understood to be its capacity; that is, the amount of fluid (gas or liquid) that the container can hold, rather than the amount of space it occupies.

Volume was measured in ancient times using similar-shaped natural containers, and later, standardized containers. Arithmetic formulas can easily calculate the volume of some simple three-dimensional shapes. Volumes of more complicated shapes can be calculated using integral calculus if a formula is provided.

The volume of the cylindrical is,

V = πr²h

V = volume

r = base radius

h = height

Calculate the difference between both sides of the equation in relation to time t. Because the radius r does not change over time, we can consider it a constant:

dv/dt = πr²(dh/dt)

Given,

dv/dt =555 cubic cm per second

r = 15

solve dh/dt:

555 = π(15)²(dh/dt)

dh/dt = 555(7/22)(1/225)

dh/dt =0.7848

The height of the sand is decreasing at a rate of 0.7848 in cm/sec

The vertices of a parallelogram are given, according to which the area of the parallelogram will be equal to 58 units.

The perimeter of a shape is its boundary's length, regarded as a whole. A form's circumference can be calculated by adding the lengths of all of its sides and edges. Utilizing linear length units like centimeters, millimeters, yards, and feet, it is determined.

The total of all a parallelogram's sides is its perimeter.

Firstly, solve for vertices AB:

AB = √(17- 1)² + (1 - 1)² = 16

Then,

BC = √(22 - 17)² + (13 - 1)² = 13

Then,

CD = √(6 - 22)² + (13 - 13)² = 16

Lastly,

AD = √(6 - 1)² + (13 - 1)² = 13

Add all the values,

P = 16 + 13 + 16 + 13

P = 58 units.

The required answers for given similar triangles are DF= 3, EF= 2.25, and scale factor 4/3 respectively.

In geometry, two geometrical triangle are similar if they have the same shape, and corresponding sides are equate by some factor. More accurately, one can be obtained from the other by uniformly scaling.

For length of side DF, ratio of corresponding sides is equal.

⇒  [tex]\frac{AB}{DE} =\frac{AC}{DF}[/tex]

⇒  [tex]\frac{2}{1.5}=\frac{4}{DF}[/tex]

⇒  DF = 3

Similarly for EF,

 [tex]\frac{AB}{DE} =\frac{BC}{EF}[/tex]

⇒[tex]\frac{2}{1.5}=\frac{3}{EF}[/tex]

⇒ EF = 2.25

At last, by using same concept of similarity scale factor is

 [tex]\frac{AB}{DE} =\frac{AC}{DF}[/tex]

⇒ [tex]\frac{AB}{DE} =\frac{4}{3}[/tex]

This is our scale factor for both triangle.

Answer:

1) B

2) B

3) C

4) A

Step-by-step explanation:

     [tex]\sf \boxed{\text{Area of cube = $6a^2$}}[/tex]

Here, a is the side of the cube.

     Area of cube = 6 * 8 * 8

                            = 384 square cm  

Option B

2) y = mx + c.

Here, m is the slope or gradient and c is the y-intercept.

Option B

3) y = -3x + 4

Compare with y =mx + c,

         where m is the gradient and c is the y-intercept.

m = -3 and  = 4

Option C

4)

[tex]\sf Slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\[/tex]

         [tex]\sf =\dfrac{-3-[-2]}{2-3}\\\\=\dfrac{-3+2}{-1}\\\\=\dfrac{-1}{-1}\\\\=1[/tex]

Option A

By evaluating the linear equation we will see that:

A = -3

B = 4

And the correct line is the purple one.

We know that the points (0, A) and (B, 0) lie on the line 3x - 4y = 12

To find the value of A, we can replace the values of the point on the line, so we get:

3*0 - 4*A = 12

-4*A = 12

A = 12/-4 = -3

A = -3

To get the value of B we do the same thing.

3*B - 4*0 = 12

B = 12/3

B = 4

So the points are (0, -3) and (4, 0).

Then the correct line is the purple one.

The inequality that represents the the possible numbers of x pairs of socks you can buy when you buy 2 pairs of sneakers, using a system of equations, is of:

y ≤ 7.

A system of equations is a set of equations involving multiple variables that are related, and then operations are made to solve these equations and identify the numeric value of each variable in the context of the problem from which the system was built.

For this problem, the variables are given as follows:

You have a $250 card to use at a sporting goods store. Each pair of sneakers is worth $80 and a pair of socks costs $12, hence the inequality regarding the total spending is:

80x + 12y ≤ 250.

When two pairs of sneakers are bought, we have that:

x = 2.

Hence the inequality regarding how many pairs of socks can be bought is:

80(2) + 12y ≤ 250.

160 + 12y ≤ 250.

12y ≤ 90

y ≤ 90/12

y ≤ 7. (rounded down, as you can buy 7 pairs of socks but not 8).

The total number of matches played in the field hockey championship are 120 matches.

Each pair of team played one match with each other.

So, let us say that there are N teams in the tournament.

So, we can chose any two teams for a match,

So, applying the permutation formula,

ⁿC₂ = 120

Solving further,

N!/2!(N-2)! = 120

N(N-1)/2 = 120

N(N-1) = 240

On observing closely and applying hit and trial method,

16(15) = 240

So, the values of N is 16.
