A trapezoid was broken into a triangle and rectangle.
The base of the triangle b is
Answer:
5
Step-by-step explanation:
when it was a trapezoid the base was 14cm but after it got split into two piecies the base for the square was 10 but the base of the triangle is half the base of the square so it must be 5.

Which statement is correct? i thought i knew this...
Answer:
D) YP is transversal to YR, SR, and SP.
Step-by-step explanation:
Neither A, B, or C are the correct options.
A is incorrect because YR and SP are parallel. This means that they can't intersect at any point.
B is incorrect because lines can only be skewed to each other if the shape is 3-Dimensional.
C is incorrect because lines YP and RS intersect at an unnamed point, not point R.
This leaves D as the only correct answer.
Hope it helps and is correct!
At a brick laying contest, each layer of bricks is expected to be of an inch tall. Three contestants recorded the fraction of layers of brick they placed and the time it took them to place the bricks in the table below.
Answer:
First, determine the number of inches each contestant made by multiplying the fraction of layers by the height of each layer.
Next, determine what fraction of an hour each contestant took to make their fraction of layers by writing each number of minutes as a fraction of 60 minutes.
Last, determine each contestant’s unit rate in inches per hour.
So, Zeke's unit rate was of an inch per hour.
Melanie's unit rate was of an inch per hour.
To find out how much greater Zeke's unit rate was than Xavier's unit rate, subtract Xavier's unit rate from Zeke's unit rate.
Therefore, Zeke's unit rate was of an inch per hour greater than Xavier's unit rate.
Step-by-step explanation:
Each contestant's unit rate in inches per hour is as Zeke's unit rate is [tex]\frac{9}{16}[/tex]inches per hour, Melanie's unit rate [tex]\frac{3}{8}[/tex] inches per hour, and Zeke's unit rate was not greater than Xavier's unit rate.
What is unit rate ?Unit rate divide the denominator with the numerator in a way that the denominator becomes [tex]1[/tex].
We have,
Each layer of brick is [tex]\frac{5}{8}[/tex] inches tall.
Zeke lays [tex]\frac{3}{5}[/tex] layers of fraction in [tex]40[/tex] minutes.
Melanie lays [tex]\frac{4}{5}[/tex] layers of fraction in [tex]80[/tex] minutes.
Xavier lays [tex]\frac{6}{5}[/tex] layers of fraction in [tex]55[/tex] minutes.
So, Number of inches made by every contestant;
Zeke lays inches of brick [tex]=\frac{5}{8} *\frac{3}{5}=\frac{3}{8}[/tex]
Melanie lays inches of brick [tex]=\frac{5}{8} * \frac{4}{5} = \frac{1}{2}[/tex]
Xavier lays inches of brick [tex]=\frac{5}{8} * \frac{6}{5} = \frac{3}{4}[/tex]
Now, Unit rate of every contestant;
Zeke's unit rate [tex]=\frac{3}{8} * \frac{60}{40} = \frac{9}{16}[/tex] inches per hour
Melanie's unit rate [tex]=\frac{1}{2} * \frac{60}{80} = \frac{3}{8}[/tex] inches per hour
Xavier's unit rate [tex]= \frac{3}{4} * \frac{60}{55} = \frac{9}{11}[/tex] inches per hour
Now, to find that how much Zeke's unit rate was greater than Xavier's unit rate:
We will find the difference between their unit rate;
i.e.
Zeke's unit rate [tex]-[/tex] Xavier's unit rate [tex]= \frac{9}{16} - \frac{9}{11} = \frac{-45}{176}[/tex]
That means Zeke's unit rate is not greater than Xavier's unit rate.
Hence, we can say that each contestant's unit rate in inches per hour is as Zeke's unit rate is [tex]\frac{9}{16}[/tex] inches per hour, Melanie's unit rate [tex]\frac{3}{8}[/tex] inches per hour, and Zeke's unit rate was not greater than Xavier's unit rate.

HEYOOO PEEPS As skydivers fall through the air, a resisting force builds up underneath them. This air resistance decreases their acceleration toward the ground, making them reach a constant velocity as they fall. This is called terminal velocity. The average terminal velocity for a skydiver is about 200 km/hr.
This speed is much too fast for a skydiver to land safely. A safe speed for a skydiver to land at is only 30 km/hr.
Resistance from the air isn’t enough to slow down a skydiver to a safe landing speed. The skydiver needs a parachute.
2. What is the role of the parachute? Explain your reasoning.
Answer: The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.
Step-by-step explanation:
ur welcome
Answer:
Your parachute allows you to descend more slowly because it lowers terminal velocity by increasing your air resistance. Most parachutes are designed to create a large amount of drag and allow you to land at a safe, low speed.
Step-by-step explanation: this is just to try and contradict the other one because the other one above me doesn't really go into explaining what is the role of the parachute so hopefully this helps bettery in clarifying details in some way shape or form.
