Answer:

Yes! 32 cm is 320 mm. I hope this helps you

Step-by-step explanation:

Answer:

32 centimeters are equal to 320 millimetres, so if compare the two:

315 __ 320

315 < 320, therefore 32 centimeters is bigger than 315 millimetres

========================================================

Explanatoin:

There are a number of ways to do this type of problem. One way is to divide the figure as shown in the diagram below. See the attached image.

I'm splitting the irregular shape into two rectangles and a triangle.

The upper rectangle is 10 miles by 9 miles to get an area of 10*9 = 90 square miles. Let A = 90 so we can use it later.

The lower rectangle is 4 miles by 19 miles. Its area is 4*19 = 76 square miles. Let B = 76.

The total vertical height of the figure is 9+4+10 = 23 miles.

Notice along the column that has "8 miles" up top over "9 miles" down below, we have a gap of some distance which I'll call x. This x adds to 8 and 9 to get the 23 mentioned.

x+8+9 = 23

x+17 = 23

x = 23-17

x = 6

This helps find the height of the triangle which is 9+x = 9+6 = 15 miles.

The triangle has a base of 9 miles.

The area of the triangle is base*height/2 = 9*15/2 = 135/2 = 67.5 square miles. Let C = 67.5

--------------

We found that:

The total area is: A+B+C = 90+76+67.5 = 233.5 square miles.

Stp-by-step explanation:

(1+x)(x2+−5x+−6)

=(1)(x2)+(1)(−5x)+(1)(−6)+(x)(x2)+(x)(−5x)+(x)(−6)

Answer:

8

Step-by-step explanation:

use second equation because it contains values as {4,5,6}

in other to get X to be 3 we have to divide 6 by 2 and replace in the equation

f (6÷2)= -(6÷2)+11

=-3 +11

=8

Answer:

Step-by-step explanation:

Cross out B and D, because angle D does not correspond with Y and Angle F does not correspond with X (order matters).

It comes down to either A or C, so look at the sides.

DF does not correspond to XY, again, the order it is displayed matters.

D is the first letter and F is the last, while X is the 2nd letter of the triangle, while it should be the first letter to correspond with D

Thus by Process of Elimination the answer is C.

(Also DF DOES correspond with WY)

Answer:

y = -10

Step-by-step explanation:

To find the y-intercept, substitute x=0.

y= (0+2)(0-5)

Then, solve the equation for y.

y = -10

Answer:

Slope is 2, and the y-intercept is (0, 4).

Step-by-step explanation:

-2x+y=4

y=4-(-2x)

y=4+2x

y=2x+4

y=mx+b where m=slope and b=y-intercept,

m=2 and b=(0, 4).

Answer:

2√5

Step-by-step explanation:

(1/2) √80

Figure out the biggest number that can be squared by 80 in this case it's 16

(1/2) √(16 x 5)

since the square root of 16 is 4 put the 4 on the outside and leave 5 in since it can't be squared.

(1/2) 4√5

multiply (1/2) by 4 which equals 2

2√5

Answer:

  9.2 m

Step-by-step explanation:

The right triangle model is shown in the attachment. The lengths 6 m and 7 m are the legs of the triangle, and the requested distance is the hypotenuse. The given Pythagorean theorem equation can be used to find the desired distance:

  c² = a² +b²

  c² = 7² +6² = 49 +36 = 85

  c = √85 ≈ 9.2

Gabe and Adele are about 9.2 meters apart.

Answer:

Total Population = Young & Institutionalized + Working Age Population

Working-Age Population = Labor Force + Not in the Labor Force

Labor Force = Employed + Unemployed

Total population = 400

Working Age Population = 300

Young & Institutionalized = 100

Not in Labor Force = 100

Labor Force = 200

Employed = 150

Unemployed = 50

Employment-population ratio = (Employed ÷ Working Age Population) x 100%

                                                 = (150 ÷ 300) × 100%

                                                 = 50%

Labor force participation rate = (Labor Force ÷ Working Age Population) x 100%

                                                 = (200 ÷ 300) × 100%

                                                 = 66.7% (nearest tenth)

Unemployment rate = (Unemployed ÷ Labor Force) x 100%

                                  = (50 ÷ 200) x 100%

                                  = 25%

Answer:

14.58 m3

Step-by-step explanation:

here, breadth (b) = 4cm

length (l) = 6cm

volume (v) = 350cm3

height (h) = ??

we know, volume of cuboid=

length × breath× height

or, v = L× B × H

or, 350 = 6 × 4 × H

or, 350 = 24 × H

or, 350/25 = H

or 14.58 = H

therefore, H = 14.58cm3

Answer:

0.9x + 0.8(x + 2)

Step-by-step explanation:

# of cans of fruit cocktail: x

# of cans of mushrooms: 2 more than x, or x + 2

$ of can of mushroom: $0.80

$ of can of fruit cocktail: $0.90

To find out how much money you spent, you need to multiply the # of cans by their respective prices. Therefore:

The price of the cans of fruit cocktail = 0.90 * x

                                                             = 0.9x

The price of the cans of mushrooms = 0.80 * (x + 2)

                                                             = 0.8(x + 2)

Total price = 0.9x + 0.8(x + 2)

Answer:

12

Step-by-step explanation:

Put numbers in order from least to greatest.

8,8,9,9,10,11,13,14,14,14,15,16.

Find the number in the middle.

Because 12 is an even number we have to take the two middle numbers, in this case 11 and 13, add them and then divide that number by 2.

11+13= 24

24 ÷ 2 =12

So the median weight is 12.

Answer:

Step-by-step explanation:

The first thing you do is put the numbers least to greatest and the middle is your answer hope you get a good grade

Step-by-step explanation:

From the graph, we know when x -> -∞, y -> 3

Note x -> -∞, 2^x -> 0

so only A and B may be right.

Note y-intercept is 7 when x = 0, so only B is right

Answer:

12

Step-by-step explanation:

Since there are 6 packs in all, and a total of 72 cards, we can multiply 6×12=72

There were 12 cards in each pack if they have 72 cards in all.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Lori and Jayden crack open six packs of baseball cards. They have a total of 72 cards.

As per the given question, the required solution would be as;

Lori and Jayden have 6 packs × c cards/pack =  cards in total.

This means that there are c = 72 cards / 6 packs = 12 cards in each pack.

Therefore, there were 12 cards in each pack.

Step-by-step explanation:

it is done by adding the first two

Answer: Option (a) x > 1/6 is the solution to the given expression -2(8x - 4) < 2x + 5.

The solution to the inequality is x > 1/6

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

-2(8x - 4) < 2x + 5

On simplifying , we get

-16x + 8 < 2x + 5

Subtracting 2x on both sides , we get

-18x + 8 < 5

Subtracting 8 on both sides , we get

-18x < -3

Multiply by -1 on both sides , we get

18x > 3

Divide by 18 on both sides , we get

x > 1/6

Hence , the solution is x > 1/6

Answer:

x=9

y=3√3

Use trig ratios

Answer:

x = 3sqr3, y = 9

Step-by-step explanation:

Use SOH CAH TOA, to solve this.

Here I know the hypotenuse, so I could use either SOH either CAH or both to find the 2 unknowns.

To find y, I would use SOH, which is Sin(angle) = opposite/hypotenuse.

When I rearrange it, I get Sin(angle)*hypotenuse = opposite. Now let's fill in with the values to give:

Sin(30)*6sqr3 = 3sqr3

And then to find x, let's use CAH, which is Cos(angle) = adjacent/hypotenuse.

Rearrange it to get Cos(angle)*hypotenuse = adjacent. This gives us a side x with a value of:

Cos(30)*6sqr3 = 9
