Answer:

27, because half of 18 is 9, so Jasmine has 9. Then you add Jasmine's amount(9) and Carly's amont(18) together.

18/2=9

18+9=27

Jonas builds a snow fort. He tells his friends it is 0.80.80, point, 8 meters tall inside, but he rounded the height to the near

laiz [17]

Answer:

D. 0.77

Step-by-step explanation:

Jonas builds a snow fort. He tells his friends it is 0.8 meters tall inside, but he rounded the height to the nearest tenth. Which could be the height of the snow fort before Jonas rounded it?

Check all options by rounding to the nearest tenth

A. 0.89 m

= 0.9 m

B. 0.74 m

= 0.7 m

C. 0.85

= 0.9 m

D. 0.77

= 0.8 m

Note: Digits 0 - 4 are rounded down while digits 5 - 9 are rounded up

Rounding to the nearest tenth means having one digits after the decimal point

A circle with center at (12,−1) passes through (0,−1). Find the circumference and area of the circle in terms of p.

madreJ [45]

Answer:

C = 75.36

A = 452.16

Step-by-step explanation:

Find the radius r by finding the distance between (12,-1) and (0,-1) using the distance formula.

$d = \sqrt{(12-0)^2 + (-1--1)^2} =\sqrt{(12)^2 + (0^2} =\sqrt{144+0} =\sqrt{144}=12$

The radius is 12.

So the circumference of the circle is $C = 2\pi r = 2\pi 12 = 24\pi = 75.36$

So the area of the circle is $A = \pi r^2\\A = \pi 12^2\\A = 144\pi\\A = 452.16$

what are the solution(s) to the quadratic equation 50 – x2 = 0? x = ±2 x = ±6 x = ±5 no real solution

Darina [25.2K]

Consider the given quadratic equation $50-x^2=0$

$x^2-50=0$

Comparing the given quadratic equation to the general equation $ax^2+bx+c=0$ , we get a= 1, b=0 and c= -50

So, the solution to the quadratic equation is given by:

$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$

$x = \frac{-0 \pm \sqrt{0^2-4(1)(-50)}}{2}$

$x = \frac{\pm \sqrt{200}}{2}$

$x = \pm \sqrt2 (5)$

$x = \pm 5\sqrt2$

So, the solutions to the given quadratic equation are $x = \pm 5\sqrt2$ .
