Answer:

13.75 inches^2

Step-by-step explanation:

The formula to find the height of the triangle is base * height over 2.

2.5 * 11 = 27.5

27.5/2=13.75

The area of the triangle is 13.75 inches

Priya has picked 1 3/4 cups of raspberries. She uses 1/5 cup of raspberries for a bottle of jam. How many bottles of jam can she

Scilla [17]

Answer:

$=8 \dfrac{3}{4} jams$

Step-by-step explanation:

Given that:

Priya has $1\dfrac{3}{4} \ cups \ of \ raspberries$

If she uses $\dfrac{1}{5} cups \ on \ jam$

∴

Then she will be able to make:

$=1\dfrac{3}{4} \div \dfrac{1}{5}$

$= \dfrac{7}{4} \times \dfrac{5}{1}$

$= \dfrac{35}{4}$

$=8 \dfrac{3}{4} jams$

A triangle has side lengths measuring 3x cm, 7x cm, and h cm. Which expression describes the possible values of h, in cm?

madreJ [45]

It would be 4x < h < 10x
the difference between 3x - 7x =4
and the sum would be 3x + 7x =10

Find the range of p in equation p(x+1) (x-3)=x-4p-2 has no real roots.

Tanya [424]

Answer:

$\displaystyle p > \frac{1}{4}$ .

Step-by-step explanation:

Expand the left-hand side of this equation:

$p\, (x + 1)\, (x - 3) = p\, \left(x^2 - 2\, x - 3\right) = p\, x^2 - 2\, p\, x - 3\, p$ .

Collect the terms, so that this quadratic equation is in the form $a\, x^2 + b\, x+ c = 0$ :

$p\, x^2 - 2\, p\, x - 3\, p = x - 4\, p - 2$ .

$p\, x^2 - (2\, p + 1)\, x + (p + 2) = 0$ .

In this equation:

$a = p$ .
$b = -(2\, p + 1)$ .
$c = p + 2$ .

Calculate the quadratic discriminant of this quadratic equation:

$\begin{aligned}b^2 - 4\, a\, c &= (-(2\, p + 1))^2 - 4\, p\, (p + 2) \\ &= 4\, p^2 + 4\, p + 1 - 4\, p^2- 8\, p = -4\, p + 1\end{aligned}$ .

A quadratic equation has no real root if its quadratic discriminant is less then zero. As a result, this quadratic equation will have no real root when $-4\, p + 1 < 0$ . Solve for the range of $p$ :

$\displaystyle p > \frac{1}{4}$ .
