Answer:

Step-by-step explanation:

So first, you know that 4 dozen doughnuts = 48 doughnuts. Next, to find how much you could get for one dollar you have the ratio $24:48 doughnuts and you can divide both sides of this ratio by 24 to get $1:2 doughnuts.

ABCD is a trapezoid. = 1 cm and = 5 cm, and the area = 7.5 cm2. What is the altitude of the trapezoid? 1.5 cm 2.5 cm 3 cm 2 cm

Ludmilka [50]

Answer:

2.5cm

Step-by-step explanation:

area of a trapeziod = 1/2 (a+b)×h

a=1cm

b=5cm

h=?

area= 7.5cm^2

••••• 7.5cm^2=1/2 (6)h

7.5= 3h

then height = 7.5/3= 2.5cm

Which is a difference of cubes? x6 – 27 x15 – 36 x16 – 64 x5 – 125

shutvik [7]

Answer:

The correct option is 1.

Step-by-step explanation:

The difference of cubes is defined as

$a^3-b^3=(a-b)(a^2+ab+b^2)$

The given expression is

$x^6-27$

It can be written as

$x^6-3^3$

Using the property of exponent, the above expression can be written as

$(x^2)^3-3^3$ $[\because (x^m)^n=x^{mn}]$

This is a difference of cubes.

Therefore the correct option is 1.

Adding and subtracting fractions 3/5 + 4/7

svlad2 [7]

Answer:

1 and 6/35

Step-by-step explanation:

You would want to multiply the denominators with the same number.

5×7

Multiply the numerators as well.

3×7 and 4×5

The fractions you would have now is 21/35 and 20/35, you can now add them up without having difficulties if the denominator is the same number.

You can also change it into decimals but I suggest this strategy.

A stone is dropped into a lake, creating a circular ripple that travels outward at a speed of 35 cm/s.

sashaice [31]

Answer:

The radius r of this circle as a function of the time t :

$r(t)=35\times t$

Step-by-step explanation:

Speed of the circular ripple = S = 35 cm/s

Radius of the ripple at time t = r

$Speed=\frac{Distance}{Time}$

$35cm/s=\frac{r}{t}$

$r=35 cm/s \times t$

The radius r of this circle as a function of the time t :

$r(t)=35\times t$
