Mathematics
1 answer:
Afina-wow [57]3 years ago
4 0

Answer:

x=19

Step-by-step explanation:

These two angles are alternate interior angles and alternate interior angles are equal when the lines are parallel

148 = 7x+15

Subtract 15 from each side

148-15 =7x+15-15

133 = 7x

Divide by 7

133/7 = 7x/7

19 =x

Calculate the length of the altitude (h) of the rhombus
allochka39001 [22]

Answer:

h = 15

Step-by-step explanation:

Use Pythagorean Theorem to solve for h.

a² + b² = c²

8² + h² = 17²

64 + h² = 289

h² = 225

h = 15

Which graph best represents the download speed of a large file
stellarik [79]

Answer:

This question is incomplete

Step-by-step explanation:

This question is incomplete. However, there are mainly four types of graphical representations in mathematics; line graph, bar graph (and histogram), pie chart and cartesian graph. The most suitable representation for fluctuating data sets of the same variables on each of the y and x-axis is the line graph. Since download speed will fluctuate during the course of a download, the correct type of graph to be used here will be the line graph. And the exact type of line graph that will be used here is a simple line graph. A simple line graph is a type of line graph in which one line is drawn on the graph. A simple line graph is usually used to represent two variables (in this case data downloaded per time).

HELP PLEASE !!!!! A person is on the top of a 60 m tall building. They throw a coin up into the air with a velocity of 15 m/s. H
Anon25 [30]

Answer:

-24.8 m/s

Step-by-step explanation:

Given:

y₀ = 60 m

y = 40 m

v₀ = 15 m/s

a = -9.8 m/s²

Find: v

There are three constant acceleration equations we can use:

y = y₀ + v₀ t + ½ at²

v = at + v₀

v² = v₀² + 2a(y − y₀)

We aren't given the time, so we need to use the third equation, which is independent of time:

v² = v₀² + 2a(y − y₀)

Plug in the values:

v² = (15 m/s)² + 2(-9.8 m/s²) (40 m − 60 m)

v² = 617 m²/s²

v ≈ ±24.8 m/s

Since the coin is on the way down, the velocity is negative.  So v = -24.8 m/s.
