goldenfox [79]

Answer:

1,267,200

Step-by-step explanation:

Given that the map reported that the scale is 1 inch to 20 miles.

Recall that there are 63,360 inches in 1 mile, thus, in 20 miles, we have 20 x 63,360 = 1,267,200

Therefore, the scale of 1 inch to 20 miles can also be represented as 1 to 1,267,200

On Sunday Sheldon bought 3 and 1/2kg of plant food. He used 1 and 2/3kg on his strawberry plants and used 1/4kg for his tomato p

notsponge [240]

The remaining plant food is: 1 7/12 kg

Step-by-step explanation:

Given

Total Plant food = 3 1/2 kg

Plant food used on Strawberry Plants = 1 2/3 kg

Plant food used on tomato Plants = 1/4 kg

We will first calculate the total food plant used and then subtract the used plant food from the total plant food.

So,

$Total\ Plant\ Food\ used=1\frac{2}{3}+\frac{1}{4}\\=\frac{5}{3}+\frac{1}{4}\\=\frac{20+3}{12}\\=\frac{23}{12}$

Now,

$Left\ Food\ Plant=3\frac{1}{2}-\frac{23}{12}\\=\frac{7}{2}-\frac{23}{12}\\=\frac{42-23}{12}\\=\frac{19}{12}\\=1\frac{7}{12}$

The remaining plant food is: 1 7/12 kg

Andy buys x cakes. Betty buys 4 times as many cakes as Andy. Colin buys 3 more cakes than Andy. Each cake costs 65p. The total c

Paladinen [302]

Answer:

Each cake cost £ 13.00

Step-by-step explanation:

We were given that, each cake costs $65p$ or £ $0.65$

Andy buys $x$ cakes.

Andy's cost is

£ $0.65x$

Betty buys 4 times as many cakes as Andy.

Betty's cost is

£ $0.65(4x)$

£ $2.60x$

Colin buys 3 more cakes than Andy

Colin's cost is

£ $0.65(x+3)$

The total cost of the cakes is £ $52.65$ .

This implies that,

$0.65x+0.65(x+3)+2.60x=52.65$

We expand to get,

$0.65x+0.65x+1.95+2.60x=52.65$

We group like terms to get,

$0.65x+0.65x+2.60x=52.65-1.95$

This gives us,

$0.65x+0.65x+2.60x=52.65-1.95$

This implies that,

$3.9x=50.7$

$x=\frac{50.7}{3.9}$

$x=13$

Therefore each cake cost £ 13.00
