Answer:

15 units

Step-by-step explanation:

From question statement, we observe that

Area of triangle and height of triangle is given.

Area = A = 52.5 square unit and Height = h = 7 unit.

We have to find the base of triangle.

Base = b =?

The formula to find the Area of triangle is:

Area = 1/2 × base ×height

Hence, base = (2 ×Area ) / height

Putting the given values in above formula, we have

base= (2×52.5) / 7

base = 105 / 7

base = 15 units

15 units is the base of given triangle.

Answer:

base = 15 units

Step-by-step explanation:

We are given area of a triangle = 52.5 sq. units

Height is given as 7 and we have to find the base.

Using formula for area of triangle:

Area of triangle = $\frac{base*height}{2}$

$52.5 = \frac{base*height}{2}$

$52.5 = \frac{base*7}{2}$

52.5 * 2 = base × 7

105 = base × 7

base = 15

A cookie recipe calls for 1/3 of a cup of sugar and 1 1/2 cups of flour. What is the unit rate of flour to sugar for the cookie

Serggg [28]

Answer:

Rate = 4.5

Step-by-step explanation:

It is given that,

A cookie recipe calls for 1/3 of a cup of sugar and 1 1/2 cups of flour.

We need to find the unit rate of flour to sugar for the cookie recipe. It can be calculated as follows :

$U=\dfrac{\text{No of cups of flour}}{\text{No of cups of sugar}}\\\\=\dfrac{1\dfrac{1}{2}}{\dfrac{1}{3}}\\\\=\dfrac{\dfrac{3}{2}}{\dfrac{1}{3}}\\\\=\dfrac{3}{2}\times 3\\\\=4.5$

So, the unit rate of flour to sugar for the cookie recipe is 4.5

Show that the equation x^3 + x -3 =0 has a solution between 1 and 2. That is the only information given

valentina_108 [34]

Answer:

Step-by-step explanation:

Given that:

$f(x) = x^3 + x - 3 = 0$

Since the given function is equal to zero, then the function :

$f(x) = x^3 + x - 3$

where;

$x = 1$ and

$x = 2$

$f(x) = (1)^3 + (1) - 3 \\ \\ f(x) = 1 + 1 - 3 \\ \\f(x) = -1 < 0$

$f(2) = x^3 + x - 3 \\ \\f(2) = (2)^3 + 3 - 3 \\ \\f(2) = 8 + 3 - 3 \\ \\f(2) = 11 - 3 \\ \\f(2) = 8 > 0 \\ \\$

Thus; f(1) < 0 and f(2) > 0

Answer:

$6\frac{2}{3}$

Step-by-step explanation:

OK, so basically I'm pretty sure that you add all of them together and put it as a fraction over 3 so basically $\frac{20}{3}$ then simplify it into $6\frac{2}{3}$
