Answer:

Area of the figure = 200 cm²

Step-by-step explanation:

Area of rectangle A = Length × Width

= 5×9

= 45 cm²

Area of rectangle B = 5 × 11

= 55 cm²

Area of rectangle C = 5 × 9

= 45 cm²

Area of rectangle D = 5 × 7

= 35 cm²

Area of rectangle E = 10 × 2

= 20 cm²

Total area of the figure = 45 + 55 + 45 + 35 + 20

= 200 cm²

An adult ticket to a museum costs 3$ more than a children’s ticket. When 200 adult tickets and 100 children tickets are sold, th

antiseptic1488 [7]

The cost of children’s ticket is $ 5

<h3><u>Solution:</u></h3>

Let "c" be the cost of one children ticket

Let "a" be the cost of one adult ticket

Given that adult ticket to a museum costs 3$ more than a children’s ticket

<em>Cost of one adult ticket = 3 + cost of one children ticket</em>

a = 3 + c ------ eqn 1

<em><u>Given that 200 adult tickets and 100 children tickets are sold, the total revenue is $2100</u></em>

200 adult tickets x cost of one adult ticket + 100 children tickets x cost of one children ticket = 2100

$200 \times a + 100 \times c = 2100$

200a + 100c = 2100 ------ eqn 2

<em><u>Let us solve eqn 1 and eqn 2 to find values of "a" and "c"</u></em>

Substitute eqn 1 in eqn 2

200(3 + c) + 100c = 2100

600 + 200c + 100c = 2100

600 + 300c = 2100

300c = 1500

Thus the cost of children’s ticket is $ 5

Answer:

y = 6x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 6 and given point (0, 4 ) ⇒ c = 4

y = 6x + 4 ← equation of line

The dimensions of a rectangular prism are shown in the diagram below. Write an expression that represents the volume of the rect

ValentinkaMS [17]

Answer:

$V=(a^{4})(b^{6})\ units^3$

Step-by-step explanation:

we know that

The volume of a rectangular prism is equal to

$V=LWH$

In this problem we have

$L=ab^2\\W=ab^3\\H=a^2b$

substitute

$V=(ab^2)(ab^3)(a^2b)$

Applying property of exponents

$x^{m} x^{n}x^{r} =x^{m+n+r}$

$V=(a^{4})(b^{6})\ units^3$
