Answer:

20 + 7 + 10 + 26 + 24 + 12 + 16 + 7 = 122cm

Answer:

The inverse is 1/2x - 3/2

Step-by-step explanation:

y = 2x+3

To find the inverse, exchange x and y

x = 2y+3

Solve for y

x-3 =2y+3-3

x-3 = 2y

Divide by 2

1/2x - 3/2 = 2y/2

1/2x - 3/2 = y

The inverse is 1/2x - 3/2

Answer:

1.) (2,1) is a solution

2.) (4,3) is NOT a solution

Step-by-step explanation:

1.) (2,1)

These are these mean (x,y)

2=x and 1=y

You want to substitute the numbers for the letters in the equation.

so.

2(2)+1=5

4+1=5

5=5, This statement is true so (2,1) is a solution.

2.) Same as above. 4=x and 3=y

4(4)-3(3)=10

16-9=10

7 Does Not Equal 10, Therefore, (4,3) is Not a solution to the equation.

Answer:

4000

Step-by-step explanation:

1 ton = 2000 pounds

2 tons = ? pounds

Multiply:

2000 × 2 = 4000

There will be 4000 pounds of crushed stone.

Hope this helped.

Sam ordered 2 tons of crushed stone. How many pounds of crushed stone does she have?

Here, we need to convert the tons into pounds to get the desired result

✪ According to the question :

We know that,

1 ton = 2000 pounds

2 tons = 2(1000 pounds) = 2000 pounds

Answer:

S = 1256

Step-by-step explanation:

S = 4[tex]\pi[/tex][tex]r^2[/tex]

S = 4[tex]\pi[/tex][tex](10)^2[/tex]

S = 4[tex]\pi[/tex][tex](100)[/tex]

S = [tex]4(314)[/tex]

S = 1256

Answer:

400pi, or 1256.637...

Step-by-step explanation:

S = 4pir^2

S = 4pi(10^2)

S = 4pi(100)

S = 400pi

Answer:

hello dear...

see first of all there's a thm type thing

'' sides opposite to equal angles are equal ''

so here 45 degrees in both sides are equal which leads us that opposite sides are equal as well

so x = 6

now we got value of 2 sides, both are 6 and now applying pythogarus as it is right angle

6^2 + 6^2 = y^2

36+36 = y^2

72 = y^2

y = √72

y = √36*2

y = 6√2

Step-by-step explanation:

By joining N to L, you will have a right angled triangle which is right angle at N. Then r^2+36=(3+x)^2. r=9/2. PQ=2r=9

Answer:

x^2-11x-12

Step-by-step explanation:

I use the box method, which makes a 2x2 box. Then you arrange you numbers based on the equation (show in image)

Then you multiply it out and get the equation

F(x)= x^2+x-12x-12

Simplify your equation and you get

F(x)= x^2-11x-12

Answer:

Step-by-step explanation:

10650

it is ten thousand

any way is this choosing or question. in my answer I answer as it is choosing. if it is question let me know in comment. I will answer again in comment

a) There are only one ten thousand.

b) There are only one two thousand.

c) There are only three ten thousand.

d) There are only seven ten thousand.

e) There are only nine ten thousand.

Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.

Given that;

Numbers are,

(a) 10650

(b) 21540

(C) 36907

(d) 74215

(e) 99999​

Now, Numbers of ten thousand are,

(a) 10650

= 10000 + 650

Hence, There are only one ten thousand.

(b) 21540

= 10000 + 10000 + 1540

Hence, There are only two ten thousand.

(C) 36907

= 10000 + 10000 + 10000 + 6907

Hence, There are only three ten thousand.

(d) 74215

= 10000 + 10000 + 10000 + 10000 + 10000 + 10000 + 10000 + 4215

Hence, There are only seven ten thousand.

(e) 99999​

= 10000 + 10000 + 10000 + 10000 + 10000 + 10000 + 10000 + 10000 + 10000 +9999

Hence, There are only nine ten thousand.

Answer:

Commercials x = 7

Movies y = 2

Step-by-step explanation:

Let commercials = x

Let's movies = y

$40 is for commercials

$110 is for movies.

Commercials plus movies for the Year = 9

She earned total of $500

X+ y = 9..... equation 1

40x + 110y = 500.... Equation 2

Multipling equation one by 40

40x + 40y = 360

Subtracting equation one from equation 2

70y = 140

Y = 2

If y = 2

X + y = 9

X + 2 = 9

X = 9-2

X = 7

f(0) = 2

Answer:

f(0) = 2

Step-by-step explanation:

Substitute x = 0 into f(x)

f(0) = - 0 + 2 = 0 + 2 = 2

[tex]\\ \sf\longmapsto \dfrac{2x-1}{3}-\dfrac{1-3x}{4}=1[/tex]

[tex]\\ \sf\longmapsto \dfrac{4(2x-1)-3(1-3x)}{12}=1[/tex]

[tex]\\ \sf\longmapsto 8x-4-3+9x=12(1)[/tex]

[tex]\\ \sf\longmapsto 17x-7=12[/tex]

[tex]\\ \sf\longmapsto 17x=19[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{19}{17}[/tex]

By way of example, suppose A = {1, 2, 3} and B = {a, b, c}. Then the Cartesian product of A and B is

A × B = {{1, a}, {1, b}, {1, c}, {2, a}, {2, b}, {2, c}, {3, a}, {3, b}, {3, c}}

That is, each element in A gets a pairing with each element in B, and for each pairing you have n(A) choices for the first element and n(B) choices for the second element.

So if n(A) = p and n(B) = q, then n(A × B) = pq.

Answer:

Step-by-step explanation:

a) By proportion number of days = 12 * 50/40

= 15 days.

b) Finding the number of bags per day that 1 chicken needs:

50 chickens eat 1 bag in 12 days

so 50 chickens eat 1/12 of a bag in 1 day.

1 chicken eats 1/(12*50) of a bag in 1 day.

20 chickens for 30 days:

20 chickens eats 20(12*50) in 1 day

and in 30 days 20 eat 30*20 / (12*50)

= 1 bag.

2.

a) 5*15 = 75 days

b) (15/10) * 5 = 7 1/2 days.

c) (15/20) * 5 = 3 * 5 /4 = 3 3/4 days.
