What's the depth of 5cm

Answer:

x + y = 24

16x + 20y = 434

x = 11.5

y = 12.5

Step-by-step explanation:

Part A:

x + y = 24

16x + 20y = 434

Part B:

simplify the second equation to find a "kind of answer" to a variable,

so we could simplify it to either y = 21.7 - 0.8x or x = 27.125 - 1.25y

in this case we will use y = 21.7 - 0.8x

substitute your new value of y into the first equation:

x + (21.7 - 0.8x) = 24

now, we can solve this to find the actual value of x: x = 11.5

so plug in your real x value to the simplified second equation (y = 21.7 - 0.8x)

you get y = 12.5

this tells you how many hours the machine spent on making each type of item

Answer:

The slant height is 28 inches

Step-by-step explanation:

The slant height of a pyramid

Given a square base pyramid of side 2a and height h, the slant height is calculated as follows:

[tex]s=\sqrt{a^2+h^2}[/tex]

The attached image shows the relationship between the lengths.

There is no specific information about the dimensions provided in the question, but I'm assuming this:

h = 22.4 in

a = 16.8 in

The slant height is:

[tex]s=\sqrt{16.8^2+22.4^2}[/tex]

[tex]s=\sqrt{784}[/tex]

s = 28 in

The slant height is 28 inches

Answer:

Width = 14 yards ; length = 25 yards

Step-by-step explanation:

Given that :

The length of a rectangular garden is 3 yd less than twice its length. The perimeter of the garden is 78 yd. What are the width and length of the garden?

Width of garden (W) = w

Lenght of garden (L) = 2w - 3

Perimeter of a rectangle : 2 (L + W)

2(2w - 3 + w) = 78

2(3w - 3) = 78

6w - 6 = 78

6w = 78 + 6

6w = 84

w = 14 yards

Length = 2(14) - 3

Length = 28 - 3 = 25 yards

Equality Properties

Step-by-step explanation:

Step 1: Define

2x < -10

Step 2: Solve for x

Here we see that any value x smaller than -5 would work as a solution.

Step 3: Identify

Answer choices.

I. -2

II. 2

III. 10

We see that none of these numbers are less than -5. Therefore, non of the answer choices are correct.

Answer: BC=18

Step-by-step explanation:

because both figures are congruent

BC is equal to B'C'

3x+12=5x+8  we solve the equations by adding and subtracting variables and numbers

3x-5x=8-12

-2x=-4 multiply by -1 and divide by 2

x=2

BC=18

Answer:

16 weeks

Step-by-step explanation:

Assuming that each month is around 4 weeks, multiply that number by 4 months and you will get 16 weeks in total.

Answer:

16

Step-by-step explanation:

there are 4 weeks in every month. Therefore, if she trained for 4 months, she trained for 16 weeks. (4*4=16)

Answer:

Step-by-step explanation:

To do this we will first use the slope formula to find the slope of the line. Given 2 points, you can't do anything else BUT find the slope. Always start there. The slope formula is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Plugging in our values from the points where y2 is 7, y1 is 3, x2 is -4 and x1 is -2:

[tex]m=\frac{7-3}{-4-(-2)}=\frac{7-3}{-4+2}=\frac{4}{-2}=-2[/tex]

So the slope is -2. Now we will pick either point and use the x and y coordinates to fill in the point-slope form of a line, which is:

[tex]y-y_1=m(x-x_1)[/tex]

where y1 and x1 are the coordinates from the point we pick, and m is the slope we just solved for. It doesn't matter which point you pick to use as your x and y coordinates; either one will give you the exact same equation...PROMISE!!

I chose (-2, 3), no reason in particular. x1 is -2 and y1 is 3:

[tex]y-3=-2(x-(-2))[/tex] which simplifies a bit to

y - 3 = -2(x + 2) and a bit more to

y - 3 = -2x - 4 and even more to

y = -2x - 4 + 3 and finally to our final line in slope-intercept form:

y = -2x - 1

Choice a.

Answer:

NonLinear line

Step-by-step explanation:

Linearity is the property of a mathematical relationship that can be graphically represented as a straight line. Linearity is closely related to proportionality. Examples in physics include the linear relationship of voltage and current in an electrical conductor, and the relationship of mass and weight.

Answer:

b = 2c:  Ben's age is twice Cindy's.  So Cindy is 15 years old

(a + b + c) / 3 = 28: Their average age is 28  This tells us nothing as we already have Anne, Ben and Cindy's ages.  It does however give us a quick way to check the answers:

[tex]\frac{a + b + c}{3} = 28\\\frac{39 + 30 + 15}{3} = 28\\\frac{84}{3} = 28[/tex]

Correct, so we know values found are correct.

Answer: Subtract 3.1 from 12.9

Step-by-step explanation:

The first step in evaluating the expression (12.9 – 3.1) × 6.2 – 2 + 43 is to open the bracket first and then subtract 3.1 from 12.9 which will give 9.8.

This follows the rule of BODMAS which says that B which stands for Bracket must be opened and solved first in a given expression.

Step-by-step explanation:

Answer:

x=-8, x=-11

Steps

(x+8)(x+11)=0

Using the zero product property

x+8 =0   x+11 =0

X+8-8 =0-8     x+11-1 = 0-11

x = -8      x = -11

Answer:

Consider the form x 2 + b x + c . Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 77 and whose sum is 18 . 7 , 11 Write the factored form using these integers. ( x + 7 ) ( x + 11 ).

Step-by-step explanation:

Answer:

Step-by-step explanation:

x^2 - 18x + 77

(x - 11)(x - 7)

Answer:

Y=-1/2x+1 because b=the y intercept or in other words, the point at which the line crosses the y axis which is at 1. -1/2x because m=the slope and since the line is going down the slope would be negative. Remember rise/run rule, to get to the next point from (0,1) the line goes down 1 and over 2 which would make it 1/2 and since it goes down it is -1/2. The x stays because that is the variable in which you substitute numbers in for to get new points. Thus the y=Mx+b that you are looking for is y=-1/2x+1

Step-by-step explanation:

What is y=mx+b?

Answer:

(0, 0) is the solution of the inequality y - 9 > 3x - 10.

Step-by-step explanation:

Given the solution point

Let us substitute the point (0, 0) in the inequality to determine which inequality satisfies the equation or not.

CHECKING FOR

y - 9 > 3x + 10

substiture (0, 0) i.e. x = 0, y = 0 in the inequality

0 - 9 > 3(0) + 10

-9 > 10

FALSE

CHECKING FOR

y - 9 > 3x - 10

substiture (0, 0) i.e. x = 0, y = 0 in the inequality

0 - 9 > 3(0) - 10

-9 > 10

True

CHECKING FOR

y + 9 > 3x + 10

substiture (0, 0) i.e. x = 0, y = 0 in the inequality

0 + 9 > 3(0) + 10

9 > 10

FALSE

Therefore, we conclude that only the second inequality i.e. y - 9 > 3x - 10 satisfies the inequality.

Hence, (0, 0) is the solution of the inequality y - 9 > 3x - 10.
