What is the value of x to the nearest tenth?
A)7.2
B)4.8
C)12.0
D)9.2
Answer:
x = 7.2
Step-by-step explanation:
a² + b² = c²
x² + (19.2/2)² = (24/2)²
x² + 9.6² = 12²
Subtract 9.6² from both sides
x² = 12² - 9.6²
x² = 51.84
x = 7.2
A line segment joins points P(-1, -7) and Q (7, 3) Determine the length of PQ to 1 decimal place?
This unit is square roots and Pythagorean Therorum.
Answer:
12.8 units
Step-by-step explanation:
PQ=(X2-X1)²+(Y2-Y1)²
=(7-(-1))²+(3-(-7)
=164

1. Express each as a unit rate.
a) A car travelled 150 km in 3 hour. Show your work.
Given:
A car traveled 150 km in 3 hour.
To find:
The unit rate.
Solution:
We have,
Distance = 150 km
Time = 3 hours.
In this case speed is the unit rate.
[tex]Speed=\dfrac{Distance}{Time}[/tex]
Substituting the given values, we get
[tex]Speed=\dfrac{150\text{ km}}{3\text{ hr}}[/tex]
[tex]Speed=50\text{ km/h}[/tex]
Therefore, the unit rate is 50 km/h.

Pam is placing a bird feeder in a tree in her back yard. She first needs to put up a 10-inch wooden platform in the fork of two tree branches that make a 52° angle, as shown below. What equation can Pam use to determine xthe distance up the tree trunk from the fork at she should drill attach the platform?
Answer:
[tex]x = \frac{10}{\tan(52^o)}[/tex]
Step-by-step explanation:
Given
See attachment for illustration
Required
Equation to find x
The relationship between angle [tex]52^o[/tex] and side lengths x and 10 inches is by tangent formula which is given by:
[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
So, we have:
[tex]\tan(52^o) = \frac{10}{x}[/tex]
Make x the subject
[tex]x = \frac{10}{\tan(52^o)}[/tex]

How is 1 over 9 a rational number?
Answer:
Because 1/9 is a fraction with integers meaning it is a fraction with whole numbers.
Step-by-step explanation:
Any number that can be written as a fraction with integers is called a rational number. For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)

Answer:
The answer is either (3) or (4) because drawing a line of best fit and finding its gradient is going to give you a negative answer
Answer:
-0.93
Step-by-step explanation:
As mentioned by Nicolas above, the line of best fit should give a negative coefficient because as x increases, y decreases.
Furthermore, since the lines do not make a perfect line, it cannot be the perfect fit, or a correlation of -1.00.
So we choose a negative answer but not -1.00 as explained previously. That lease the only choice of -0.93, by elimination without doing any calculations.
PLEASE I NEED THE ANSWER DON'T IGNORE MY QUESTION!!! Solve for X for the following
Answer:
Fig. 1 :- 7.6
Fig. 2 :- 15
Step-by-step explanation:
We can use Pythagoras theorem to solve for x
[tex]c^{2} =a^{2} +b^{2}[/tex]
Figure 1:
[tex]c^{2} =7^{2} +3^{2}[/tex]
[tex]c^{2} =49+9[/tex]
[tex]c^{2} =58[/tex]
[tex]c=\sqrt{58}[/tex]
[tex]c=7.615773106[/tex]
You can now round your answer:
[tex]c=7.6[/tex]
Figure 2:
[tex]c^{2} =12^{2} +9^{2}[/tex]
[tex]c^{2} =144+81[/tex]
[tex]c^{2} =225[/tex]
[tex]c=\sqrt{225}[/tex]
[tex]c=15[/tex]
I hope this helps :)
Step-by-step explanation:
fig(1)
h=x
p=3
b=7
now,
h^2=p^2+b^2. (by Pythagoras theory)
or, x^2=3^2+7^2
or, x^2=9+49
or, x^2=58
or, x=√58
fig(2)
h=x
p=12
b=9
now,
h^2=p^2+b^2
or, x^2=12^2+9^2
or, x^2=144+81
or, x^2=225
or, x=15

Graph a line that contains the point (-6,1) and has a slope of 5
Answer:
Step-by-step explanation:
Equation of a line passing through a point (h, k) and slope 'm' is given by,
y - h = m(x - k)
Equation of a line passing through (-6, 1) and slope = 5,
y - 1 = 5(x + 6)
y = 5x + 31

According to Chad, all intersecting lines form right angles.
If he's right, explain why.
A. Chad is correct because intersecting lines are always perpendicular.
B. Chad is incorrect because intersecting lines are never perpendicular.
C. Chad is incorrect because intersecting lines are sometimes perpendicular.
D. Chad is correct because intersecting lines are sometimes perpendicular.
Answer:
C. Chad is incorrect because intersecting lines are sometimes perpendicular.
Step-by-step explanation:
SOMETIMES perpendicular (90 degree angle, aka right angle) not always.
Chad is incorrect because intersecting lines are sometimes perpendicular.
What are perpendicular lines?If the angle between two lines is 90 degrees, lines are called perpendicular lines.
If two lines intersect each other, it is not necessary that they will intersect at 90°.
Sometimes they can intersect at 90° and sometimes not.
So, Chad is incorrect because intersecting lines are sometimes perpendicular.
Hence, Chad is incorrect because intersecting lines are sometimes perpendicular.
