Answer:

A) 150

Step-by-step explanation:

All the angles in a triangle must add up to a total of 180 degrees.

So we can make an equation as given below:

20+10+?=180

30+?=180

?=150

So the missing angle is 150 degrees

A ball is thrown into the air with a initial velocity of 25 meters per second.The function h(t)+-4.9t^2+25t+6 represents the hei

Rainbow [258]

Answer:

36.9 m

Step-by-step explanation:

h(t) = -4.9t² + 25t + 6

At t = 3:

h(3) = -4.9(3)² + 25(3) + 6

h(3) = -44.1 + 75 + 6

h(3) = 36.9

After 3 seconds, the ball will have a height of 36.9 meters.

Write the equation of the circle in standard form: Center (7,0) R=1

Mice21 [21]

Answer:

$(x-7)^2+y^2=1$

Step-by-step explanation:

Hi there!

Equation of a circle: $(x-h)^2+(y-k)^2=r^2$ where the circle is centered at (h,k) and the radius is r

<u>1) Plug in the given center (7,0)</u>

$(x-7)^2+(y-0)^2=r^2\\(x-7)^2+y^2=r^2$

<u>2) Plug in the radius (1)</u>

$(x-7)^2+y^2=1^2\\(x-7)^2+y^2=1$

I hope this helps!

Find the probability. Round your answer to the nearest hundredth, if needed.

padilas [110]

Answer:

0.2

Step-by-step explanation:

Given:

Total number of students = 20

Number of students who have brown hair = 12

Number of students who have blonde hair = 4

Number of students who have red hair = 3

Number of students who have black hair = 1

To find:

Probability of randomly selecting a blonde-haired student from the classroom.

Solution:

Probability refers to chances of occurring of some event.

Probability = Number of favourable outcomes/ Total number of outcomes

Number of favourable outcomes ( Number of students who have blonde hair ) = 4

Total number of outcomes = 20

So,

Probability of randomly selecting a blonde haired student from the classroom = $\frac{4}{20}=\frac{1}{5}=0.2$

Add together 2350mm 3.42cm 11/2m and 1.45m

Artyom0805 [142]

9.3342meters because you convert 2350mm into m which is 2.35m, + and also convert 3.42cm to m which is 0.0342 then + 1.45m +11/2m= 9.3342m
