Answer:

answer is 2400

Step-by-step explanation:

6/100×40'000=2400

The perimeter and the area of the shape are 63 square yards and 46 yards, respectively.

The area of a triangle is equal to one half the product of its base and height. In the image, the base of the triangle is 18 yards and the height is 7 yards. Therefore, the area of the triangle is:

area = (1/2) * base * height

= (1/2) * 18 * 7

= 63 square yards

The perimeter of the shape is the sum of the lengths of all of its sides. In the image, the lengths of the sides are 6 yards, 18 yards, 7 yards, and 15 yards.

Therefore, the perimeter of the shape is:

perimeter = 6 + 18 + 7 + 15

= 46 yards

Answer:

Given,

Dimensions of rectangular prism

Length= 10in

Breadth=2in

height= 3(1/2) or 7/2

Dimension of cube = 1/2in

Let the number of cubes be x

A.T.Q(According to question)

Vol. of rectangular prism= Vol. of Square× Number of cubes

l×b×h = a³

= > 10×2×7/2 = (1/2)³× x

x = 560

So the number of cubes required to fill the prism is. 560

Answer:

Andrew is 30 years old. Hunter is 65 years old.

Step-by-step explanation:

we can set up 2 equations:

h = 35 + a

h+5 = 2(a+5)

Solve for h in the second equation.

h + 5 = 2a + 10; h = 2a + 5

now set the 2 equations = to each other

2a + 5 = 35 + a

solve for a by combining like terms

a + 5 = 35

a = 30

so Andrew is 30 and Hunter is 35 + 30 = 65.

Sp in 5 years Andrew is 35 and Hunter is 70 (twice A's age)

Answer:

So that means that

h=35+a+5

because he already is 35

we add Andrew's Age

And we add 5 for 5 extra years

Therefore,

35+5=40.

40+a = 2a+10

Substract the a

40 = a+10

Subtract 10

30 = a

If Andrew's age is 30, going back to our first equation,

Hunter's Age = 65

Andrew's Age = 30

Answer:

surface area of cuboid = 190 in²

surface area of triangular prism = 1240 yd²

surface area of cone = 791.28 ft²

Step-by-step explanation:

cuboid formula = 2( l x b + l x h + h x b )

solution:

S.A = 2(l x b + l x h + h x b)

S.A = 2(5 x 3 + 5 x 10 + 10 x 3)

S.A = 2(15 + 50 + 30)

S.A = 2( 95 )

S.A = 190 in²

triangular prism formula = 2(1/2 (b x h)) + 2(l x b) + l x b(this formula can only be used for this type of triangular prism)

solution:

S.A = 2(1/2 (b x h)) + 2(l x b) + l x b

S.A = 2(1/2 (15 x 16)) + 2(17 x 20) + 20 x 16

S.A = 240 + 680 + 320

S.A = 1240 yd²

cone formula = [tex]\pi[/tex]r(l + r) or [tex]\pi[/tex]rl + [tex]\pi[/tex]r²

solution:

S.A = [tex]\pi[/tex]r[l+r]

S.A = 3.14(9)[19 + 9]

S.A = 28.26 x 28

S.A = 791.28 ft²

Answer:

0.027

Step-by-step explanation

If s = 0.3, and s is being cubed, that's the same as 0.3 cubed

Cubed just means to the third power.

So that mean o.3 cubed is the same as (0.3)(0.3)(0.3)

Therefore, the answer is 0.027

Answer:

(A) 33.9 (B) 22.6

Step-by-step explanation:

We first need to round to the nearest dollar for both prices. Lets examine both numbers.

$30.12       $19.93

We can round $30.12 to $30 since the number in the tenths place is 1 and we can round $19.93 to $20 since there is a nine in the tenths place.

Now we must find the tax for each number. We can do that by multiplying each number by 0.13 since that is 13% in decimal form. Lets do that now

[tex]30*0.13=3.9[/tex]           [tex]20*0.13=2.6[/tex]

Now we can find the final price for each number by adding the tax to the rounded price.

[tex]30+3.9=33.9[/tex]          [tex]20+2.6=22.6[/tex]

Hence, (A) 33.9, (B) 22.6

The fraction that represents the addition model shown above will be 53/100.

From the information given, a grid with 10 equal columns is shown with 5 shaded in. This will be expressed as 5/10.

Also, a second grid is shown, identical in size, containing 100 squares with 3 shaded in. This will be expressed as 3/100.

Therefore, the problem that represents the addition model shown above will be:

= 5/10 + 3/100

= 50/100 + 3/100

= 53/100

The linear inequality represented by the graph is y ≤ 1/2x + 2

From the graph, we have the following highlights:

Next, we calculate the slope (m) using:

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

Using the points on the graph, we have:

[tex]m = \frac{4 -2}{4 -0}[/tex]

Evaluate

m = 1/2

The first highlight implies that the y-intercept is 2.

So, the linear inequality is:

y ≤ mx + c

This gives

y ≤ 1/2x + 2

Hence, the linear inequality represented by the graph is y ≤ 1/2x + 2
