Answer:

1) $= 10 \frac{2}{5} = \frac{52}{5}$

2) $= \frac{252}{25} = 10 \frac{2}{25}$

Step-by-step explanation:

$6 \frac{4}{5} + 3 \frac{3}{5} \\ (6 + 3) + ( \frac{4}{5} + \frac{3}{5} ) \\ 9 + \frac{7}{5} = 9 + 1 \frac{2}{5} \\ 9 + 1 + \frac{2}{5} = 10 + \frac{2}{5}$

$\boxed{\green{= 10 \frac{2}{5} = \frac{52}{5}}}$

Answer:

[?] = 4

(the complete term is $4\frac{1}{2}\ \text{cups}$ )

Step-by-step explanation:

$8\ \text{cups} - 1\frac{1}{3}\ \text{cups} - 2\frac{1}{6}\ \text{cups} = (8-1-2)\ \text{cups} + \frac{-\frac{6}{3} - 1}{6}\ \text{cups} = 5\ \text{cups} + \frac{-3}{6}\ \text{cups} = 5\ \text{cups} + \frac{-1}{2}\ \text{cups} = 4\ \text{cups} + \frac{2 - 1}{2}\ \text{cups}$

You have a gift card for a coffee shop worth $90. Each day you use the card to get a coffee for $4.10. Write an explicit formula

Fiesta28 [93]

Answer: The value of the card after you buy your 8th coffee will be $61.3

Step-by-step explanation:

The worth of the gift card for the coffee shop is $90. Each day you use the card to get a coffee for $4.10. This means that the worth of the gift card is reducing by $4.10 each day. This rate is in arithmetic progression.

The formula for the nth term of an arithmetic sequence, Tn is expressed as

Tn = a + (n-1)d

Where a is the first term

d is the common difference

n is the number of days

From the information given,

a = $90

d = - $4.1

The explicit formula representing the amount of money available will be

Tn = 90 - 4.1(n - 1)

The value of the card after you buy your 8th coffee will be

T8 = 90 - 4.1(8 - 1) = T8 = 90 - 4.1×7

T8 = 90 - 28.7

T8 = $61.3

Oven tray 700mmx600mm, how many cake tins 25cm can fit on the oven tray.

murzikaleks [220]

All we need to do is to find out how many 25 cm cake tins will fit along the 70 cm edge (70 cm because 700 mm = 70 cm).

70 : 25 = 2,8

It means that 2 and 0,8 tins will fit, which is generally 2 tins because the third one wouldn't fit.

Now we have to do the same with the 60 cm edge:

60 : 25 = 2,4

So again we'll have 2 tins along the other edge, but with less spare space.

Now we just have to multiply both edges to get the amount of the tins that will fit on the tray:

2 * 2 = 4

Answer: 4 cake tins will fit on oven tray measuring 700mm x 600mm.

What are the solutions to the equation? x^2+6x = 40.

GaryK [48]

Answer:

x = 4, -10

Step-by-step explanation:

Find the zeros of the equations.

Solve the equation:

x^2 + 6x = 40

Subtract -40 from both sides.

x^2 + 6x - 40 = 0

Factor the equation.

(x - 4)(x + 10)

Solve for x with the given information by equaling it to 0.

x - 4 = 0

Add 4 to both sides

x = 4

x + 10 = 0

Subtract 10 from both sides

x = -10

This means that our x values are:

x = 4, -10
