Answer:

OPtion A Zahra cannot make a triangle with these angle measures.

Step-by-step explanation:

To draw a triangle we must have atleast 3 independent dimensions

Here only 2 are given as third angle depends on first 2.

Hence Zahra cannot make a triangle with these angle measures.

If at all she wants to draw she has to assume some side atleast one side and make triangle

But this is infinite as she can do for any size of her choice.

The perimeter of the rectangle is 19.4 centimeters.What is the width in centimeters,of the rectangle Length is 6cm

guajiro [1.7K]

SOLUTION

From the question, the Perimeter of the rectangle is 19.4 cm and we want to find the width. The perimeter of a rectangle is given by

$\begin{gathered} P=2\left(l+w\right) \\ where\text{ P =perimeter = 19.4} \\ l=length\text{ of rectangle = 6 cm} \\ w=width=? \end{gathered}$

Applying this, we have

$\begin{gathered} P=2\left(l+w\right) \\ 19.4=2\left(6+w\right) \\ 19.4=12+2w \\ 2w=19.4-12 \\ 2w=7.4 \\ w=\frac{7.4}{2} \\ w=3.7 \end{gathered}$

Hence the width is 3.7 cm, option C

A football thrown by a quarterback follows a path given by hx=-0.0095x2+x+7, where h is the height of the ball in feet and x is

Wewaii [24]

Answer:

The ball can be knocked down at a horizontal distance of 3.09 feet or 102.17 feet from the marshal.

Step-by-step explanation:

We have the function that represents the height h (x) of the ball $h(x) = -0.0095x^2 + x + 7$

Where x is the horizontal distance of the ball.

We want to find the horizontal distance the ball is at (horizontal distance between the field marshal and the ball) when it is at a height of 10 feet.

To do this, we must do h (x) = 10

$10 = -0.0095x^2 + x + 7\\0 = -0.0095x^2 + x -3$

Now we must solve the second degree equation. For this we use the formula of the resolvent:

$\frac{-b + \sqrt{b ^ 2 - 4 * a * c}}{2a}$

and

$\frac{-b - \sqrt{b ^ 2 - 4 * a * c}}{2a}$

$\frac{-1 + \sqrt{1 ^ 2 - 4 * (- 0.0095)(-3)}} {2 (-0.0095)} = 3.09$ ft

and

$\frac{-1 - \sqrt{1 ^ 2 - 4 * (- 0.0095)(-3)}} {2 (-0.0095)} = 102.17$ ft

Then, the ball can be knocked down at a horizontal distance of 3.09 feet or 102.17 feet from the marshal.

Christopher is 20 years younger than Ishaan. Ishaan and Christopher first met two years ago. Fourteen years ago, Ishan was 3 tim

liq [111]

Answer:

Let Ishaan's age be x. Then, Christopher's age is x-20. These are their current ages.

14 years ago,

x-14 = 3(x-20-14) (we need to subtract 14 from both of their ages')

x - 14 = 3(x - 34)

x - 14 = 3x - 102

2x = 88

x = 44

Ishaan is 44 years old now.
