Answer:

t= 2.22 seconds.

Step-by-step explanation:

1) You need to find the vertical velocity.

38*sin(35) = 21.7959

2) You need to use the t=v1y/a formula to find the time to get to the top.

v1y= the vertical velocity, 21.7959

a= Acceleration, 9.8

t=21.7959/9.8

t=2.22

horrorfan [7]

There'll be 5 parents that'll go to the museum

Let the number of parents that will go to the museum be represented by x.

Based on the information given, the equation to use will be:

15/75 = x/25

Cross multiply

75 × x = 15 × 25

75x = 375

Divide both side by 75

75x/75 = 375/75

x = 5

Therefore, there'll be 5 parents that'll go to the museum.

Determine if triangle OPQ and triangle RST are or are not similar, and, if they are, state which triangle similarity shortcut (A
murzikaleks [220]

Answer:

SAS Similarity

Step-by-step explanation:

ΔOPQ similar to ΔRST

∠Q  = ∠T

OQ : RT = 28 : 84 = 1 : 3

QP : TS  = 16 : 48 = 1 : 3

The measures of two sides of ΔOPQ are proportional to the measure of two side of ΔRST and their included angles are congruent.  The triangles are similar by SAS Similarity.

Lubov Fominskaja [6]

Answer:

(A)If the points are on the same line, then the points are collinear. True

Step-by-step explanation:

Given the conditional statement:

  • Collinear points are on the same line.

Its converse will be:

  • If the points are on the same line, then the points are collinear.

This is true because by definition of collinearity, the points must be on the same line. Therefore, no counter example is needed.

<u>The correct option is A.</u>

Find the area of the smaller sector ​
Digiron [165]

Since the radius is 6 inches, the area is

A=\pi r^2=36\pi squared inches.

Now, the full circle is a sector given by a 360° angle. So, the area of a 140° angle will be proportionate:

140\div x = 360\div 36\pi

Solving for x, we have

x=\dfrac{36\pi\cdot 140}{360}=14\pi
