Solve the proportion 16/50= X156.25

Ami buys x apples and y bananas. The apples cost 15p each and the bananas cost 20p each. The total cost of Ami's apples and bana

Bezzdna [24]

Answer:

0.15x + 0.20y = 1.80

Step-by-step explanation:

Here, we are interested in writing an equation for the total cost of the apples and bananas

before we write , kindly understand that 100p = £1

So the cost of apple which is 15p will be 15/100 =£ 0.15

The cost of bananas which is 20p will be 20/100 = £0.2

Thus, the total cost of the apples bought will be number of apples bought * price of apple bought = 0.15 * x = £0.15x

The cost of bananas = number of bananas bought * price of bananas = 0.2 * y = £0.2y

So the total cost of the apples and bananas will be;

0.15x + 0.20y = 1.80

The price of an item in a shopping cart is c dollars. If the sales tax on the item is 9%, and the expression c + 0.09c represent

Crank

If you factor c + 0.09c, we get c(1 + 0.09), which is the same as (1 + 0.09)c.

If we add the numbers inside the parentheses (1 + 0.09)c we get 1.09c.

The answer is choice B and E.

The base of a triangle is one third as long as its height. if the area of the triangle is 6 square meters, how long is its base

KIM [24]

The answer is:  " 2 m" .
________________________________________
Explanation:
_________________________________________
The formula for the area, "A" , of a TRIANGLE is:
_________________________________________
A = (1/2) * b * h ; or, write as: " A = (b * h) / 2 " ;
_________________________________________
in which: A = area of triangle;
b = length of base;
h = [perpendicular] height .
_________________________________________
We are given: "b = 1/3 h = h/3" ;
"A = 6 m²: "

We are asked to solve for "b" ;

So: "A = ( b * h) / 2 " ;

→ Re-arrange the equation to isolate "b" on one side of the equation ;

→ "A = ( b * h) / 2 " ; ;

Multiply EACH SIDE of the equation by "2" ;
→ 2 * A = { ( b * h) / 2 } * 2 " ;

to get:

→ 2A = b * h ;

↔ b * h = 2A ;

NOTE: Calculate "2A" ; as follows: " 2A = 2* 6 m² = 12 m² " ;

→ b * h = 12 m² ;

Note: "b = h/3 " ;

So rewrite:

→ "b * h = 12 m² ;

as: (h/3) * h = 12 m² ;

→    $\frac{h}{3}$ * $\frac{h}{1}$ = 12 m² ;

→ $\frac{(h*h)}{(3*1)} = \frac{h^2}{3} =$ = 12 ;

→ Now, we can solve for "h" ; {and then, solve for "b" }..
___________________________________________________
We have: \frac{h^2}{3} = [/tex] = 12
______________________________________________________
  → h² = 12 * 3 ;

→ h² = 36 ;

Now, take the positive square root of EACH SIDE of the equation;
to isolate "h" on one side of the equation; & to solve for "h" ;

  → +√(h²) = +√36 ;

  → h = 6 m ;

Now, we can solve for "b" ;

b = h / 3 = 6 m / 3 = 2 m .

→ b = 2 m .
________________________________________

The answer is: " 2 m" .
________________________________________
Let us check our answer:
________________________________________
A = (b * h) / 2 ;

→ 6 m² = ? (2 m * 6 m) / 2 ?? ;

  → 6 m² = ? (12 m²) / 2 ?? Yes!
