how would I solve this
Answer:
5√5
Step-by-step explanation:
Hypotenuse (h) = 15
perpendicular (p) = 10
base (b) = ?
We know by using Pythagoras theorem
b = √h² - p²
= √ 15² - 10²
= √ 125
= 5√5
Hope it will help :)
Answer:
≈11.2
Step-by-step explanation:
a²+b²=c²
10²+b²=15²
100+b=225
-100 on both sides
b= √125= 11.2
What is the solution to the equation 4x-6= 10x-3?
X=-2
O X=2
O X=
O X= 2
Answer:
the first one x = -2
Step-by-step explanation:
Let's solve your equation step-by-step.
4x−6=10x−3
Step 1: Subtract 10x from both sides.
4x−6−10x=10x−3−10x
−6x−6=−3
Step 2: Add 6 to both sides.
−6x−6+6=−3+6
−6x=3
Step 3: Divide both sides by -6.
Answer:
x = -1/2
Step-by-step explanation:
4x - 6 = 10x - 3
+6 +6
4x = 10x + 3
-10x -10x
-6x = 3
3 / -6 = -1/2
Item 4 Write a proportion to find how many points x a student needs to score on a test worth 50 points to get a test score of 40%
Answer:
20 points
Step-by-step explanation:
We need to find how many points x a student needs to score on a test worth 50 points to get a test score of 40%.
Let x be the number of points.
ATQ,
[tex]\dfrac{x}{50}=\dfrac{40}{100}\\\\x=\dfrac{50\times 40}{100}\\\\x=20[/tex]
Hence, a student needs 20 points to get a score of 40%.

what is 2(x+6)-6x in simplest form
Answer:
-4x + 12
Step-by-step explanation:
2(x+6)-6x
2x + 12 - 6x
combine llike terms
2x - 6x = -4x
-4x + 12
Answer:
2(x+6)-6x=-4x+12
Step-by-step explanation:
So how I got that was I expanded 2(x+6): 2x+12 so I got 2x+12-6x
I simplified 2x+12-6x and I got -4x+12

Suppose there are exactly 9 people on a bus in Seattle, and the average of their yearly incomes is $65,000. At the next stop, the highest paid person on the bus (with an income of $120,000 per year) gets off, and Bill Gates gets on. Mr. Gates makes 7.6 billion dollars a year. Q9a: What is the new average salary of people on the bus?
Answer:
$844496111
Step-by-step explanation:
Size, n = 9
Initial average = 65000
Average = total sum / size
Initial Sum = 9 * 65000
Initial sum = $585,000
New average = ((585,000 - 120,000 + 7,600,000,000)) / 9
New average =
$7600465000 / 9
= $844496111. 11
= $844496111

The angles shown are supplementary. What is the value of x ?
Answer:
D
Step-by-step explanation:
This is because if u subsitute x with 17, 17x5 is 85 and 85+95= 180
[tex]\color{plum}\tt\bold{(D) \: 17}[/tex]
○=> Steps to derive correct answer :Given :
▪︎Angle (5x)° and angle 95° are supplementary angles.
Which means :
[tex] = \tt5x + 95 = 180[/tex]
[tex] = \tt5x = 180 - 95[/tex]
[tex] = \tt5x = 85[/tex]
[tex] \hookrightarrow\tt \color{plum}x = 17[/tex]
Thus, the value of x = 17
Let us check whether or not we have found out the correct value of x by placing 17 in the place of x:
[tex] =\tt5 \times 17 + 95 = 180[/tex]
[tex] =\tt 85 + 95 = 180[/tex]
[tex] =\tt 180 = 180[/tex]
Since the sum of both angles is equivalent to 180[85+95=180], we can conclude that we have found out the correct value of x.
Therefore, the correct option is (D) 17

In the Data set below, what is the standard deviation?
4 2 8 5 7
Answer:
The standard deviation of the given data set
σ = 2.135
Step-by-step explanation:
Step(i):-
Given numbers are 4 2 8 5 7
Mean of the numbers
[tex]= \frac{4+2+8+5+7}{5}[/tex]
= 5.2
The mean of the numbers (μ) = 5.2
Step(ii):-
x : 4 2 8 5 7
x-μ : -1.2 -3.2 2.8 -0.2 1.8
(x-μ)² : 1.44 10.24 7.84 0.04 3.24
The standard deviation of the given data
σ = √Σ( x-μ)² / N
σ = [tex]\sqrt{ \frac{1.44+10.24+7.84+0.04+3.24}{5}}[/tex]
σ = 2.135

Name two points on the line y = 6x. Does it describe a
proportional relationship?
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.

Enter the measure of ZCAB to the nearest hundredth degree.
Step-by-step explanation:
sinA=p/h
sinA=12/15
A=sin-¹(4/5)=53.13=53°
<CAB=53°
The measure of ∠CAB is 53°.
What is Trigonometry?The trigonometric function, which comprises the sine, cosine, tangent, cotangent, secant, and cosecant, is one of the six mathematical operations used to describe the side ratios of right triangles (csc).
As per the given data:
From the given diagram, we can clearly understand that the triangle is a right-angled triangle which is right-angled at C.
We have to find out the measure of ∠CAB.
The lengths of the sides BC and AB is also given in the diagram.
For finding out the measure of ∠CAB we can consider BC as the perpendicular and AB as the hypotenuse, and then we have to use the appropriate trigonometric ratio.
The length of the perpendicular BC = 12 units
The length of the hypotenuse AB = 15 units
For relating perpendicular and hypotenuse, we can use the sin trigonometric ratio.
sinθ = Perpendicular / Hypotenuse
sinθ = BC / AB
sinθ = 12 / 15
sinθ = 4 / 5
θ = 53°
The measure of ∠CAB is 53°.
Hence, The measure of ∠CAB is 53°.
