Find the measure of the missing angle.
Answer:
50
Step-by-step explanation:
40+90=130
180-130=50
Answer:
The measure of the missing angle is 50°.
Step-by-step explanation:
☆A triangle equals 180°.
☆A right angle equals 90°
☆We have two angles given to us, however one out of the two angles might be tricky for some to figure out.
☆An angle, we obviously see, is 40°.
☆The right angle, (the one with a box) equals 90°, so therefore, the value of that angle is 90°.
☆In order to find the value of the last angle, we are going to have to subtract the sum of both numbers from 180°.
☆We are subtracting it from 180° because a triangle equals 180°.
☆An equation would look like:
[tex]40 + 90 + x= 180[/tex]
☆The X indicated in the equation represents the unknown angle.
☆Let's solve the equation.
☆[tex]40 + 90 + x = 180 \\ 130 + x = 180 \\ \frac{ - 130 \: \: \: \: \: \: = - 130}{x = 50} [/tex]
☆Without an equation, you could just add both angles, and subtract it from 180.
☆[tex]40 + 90 = 130 \\ 180 - 130 = 50[/tex]
☆Therefore, the missing angle is 50°.

log x + log (x - 6) =3
Answer:
x = 3 + sqrt(e^3 + 9)
Step-by-step explanation:
Solve for x over the real numbers:
log(x) + log(x - 6) = 3
Hint: | Combine logarithms.
log(x - 6) + log(x) = log(x (x - 6)):
log(x (x - 6)) = 3
Hint: | Eliminate the logarithm from the left hand side.
Cancel logarithms by taking exp of both sides:
x (x - 6) = e^3
Hint: | Write the quadratic polynomial on the left hand side in standard form.
Expand out terms of the left hand side:
x^2 - 6 x = e^3
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 9 to both sides:
x^2 - 6 x + 9 = e^3 + 9
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 3)^2 = e^3 + 9
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 3 = sqrt(e^3 + 9) or x - 3 = -sqrt(e^3 + 9)
Hint: | Look at the first equation: Solve for x.
Add 3 to both sides:
x = 3 + sqrt(e^3 + 9) or x - 3 = -sqrt(e^3 + 9)
Hint: | Look at the second equation: Solve for x.
Add 3 to both sides:
x = 3 + sqrt(e^3 + 9) or x = 3 - sqrt(e^3 + 9)
Hint: | Now test that these solutions are correct by substituting into the original equation.
Check the solution x = 3 - sqrt(e^3 + 9).
log(x) + log(x - 6) ⇒ log((3 - sqrt(e^3 + 9)) - 6) + log(3 - sqrt(e^3 + 9)) = 2 i π + 3 ≈ 3 + 6.28319 i:
So this solution is incorrect
Hint: | Check the solution x = 3 + sqrt(e^3 + 9).
log(x) + log(x - 6) ⇒ log(3 + sqrt(e^3 + 9)) + log((3 + sqrt(e^3 + 9)) - 6) = 3:
So this solution is correct
Hint: | Gather any correct solutions.
The solution is:
Answer: x = 3 + sqrt(e^3 + 9)

Answer:
x = 3 + √1009 ≈ 34.765
Step-by-step explanation:
Take the antilog and solve the resulting quadratic.
x(x -6) = 10^3
x^2 -6x +9 = 1009 . . . . . . add (-6/2)^2 to complete the square
(x -3)^2 = 1009 . . . . . . . . . write as a square
x = 3 + √1009 ≈ 34.765 . . . . . square root and add 3
__
Only the positive root makes any sense, since the log of a negative number is not defined (in real numbers).
__
For the graph, we subtracted 3 so we are looking for the x-intercept where f(x)=0.

The sales tax on clothing that cost $24 is $1.68. How much would sales tax be on clothing that cost $96?
Answer:
$6.72
Step-by-step explanation:
1.68 is 7% of 24, so there is a 7% tax.
96x.07= 6.72
Answer: The sales tax would be 6.72
Step-by-step explanation: 24 is 1/4 of 96 so that means that you have to multiply the sales tax number by 4 and 1.68 x 4 = 6.72

∠aangle, a and \angle b∠bangle, b are complementary angles. \angle a∠aangle, a measures 22^\circ22 ∘ 22, degrees. What is the measure of \angle b∠bangle, b?
Answer:
68 degrees
Step-by-step explanation:
The sum of two complementary angles is 90 degrees
If <a and <b are complementary, then;
<a + <b = 90
Given
<a = 22 degrees
Required
<b
Substitute into the given expression;
22 + <b = 90
<b = 90-22
<b = 68 degrees
Hence the measure of <b is 68 degrees

Venus is average distance from the sun is 108 million KM. This distance is 42 million KM less than the average distance from the sun to earth. Right and solve an equation to find earths average distance D from the sun.
Answer: 150 million km
Step-by-step explanation:
From the question, we are informed that the average distance of Venus from the sun is 108 million km which is about 42 million km less than the average distance from the sun to earth.
Therefore, the Earths average distance D from the sun will be calculated as:
= 108 + 42
= 150 million km
A telephone poll of an SRS of 1234 adults found that 62% are generally satisfied with their lives. The announced margin of error for the poll was 3%. Does the margin of error account for the fact that some adults do not have telephones
Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling

recipe is 14:12. Which ratio is equivalent to 14:12?
Answer:
7:6
Step-by-step explanation:
I simplified 14:12
Step-by-step explanation:
Since 14 and 12 are both even numbers, they are a multiple of 2.
14 = 2 * 7
12 = 2 * 6
Therefore 14:12 = (2*7):(2*6) = 7:6.
The equivalent ratio is 7:6.

A bird starts at 20m and changes to 16m? The bird's final elevation is
Answer:
Kindly check explanation
Step-by-step explanation:
The initial elevation is 20m
According to the question :
If it changes to 16m, then the final elevation of the bird is 16 m.
However, in some texts, the question goes thus;
A bird starts at 20m and changes 16m? The bird's final elevation is?
In this case, the initial height = 20m
Change in height = 16 m (positive means ascension)
Hence,
initial height + change in height
20 m + 16 m
= 36m

You are 18 miles away from home. You start biking home at a speed of 6 miles per hour. Write an equation in slope-intercept form that represents the distance away from home "y" after "x" hours. Y= How many hours will it take to get home? Hours
Answer:
y = 18 - 6x
Step-by-step explanation:
Given :
Speed or rate = 6mph
y = distance away from home
x = hours biked
Initial distance from home = 18 miles
General form of Slope - intercept form of an equation :
y = mx + c
Where ;
m = gradient or slope = rate of change
c = intercept or initial value or amount, always constant
x = independent variable
y = dependent variable
Hence,
For the question above :
Distance away from home, depends on the number of hours biked
y = 18 - 6x

Step-by-step explanation:
Which size Dairy Queen blizzard gives you the best price per ounce
Small 6oz. Cup for $2.49
Large 16oz. Cup for $4.98
Medium 10oz. Cup for $3.49
Supper size 24oz. Cup for 7.69
The Large blizzard has the lowest cost per ounce at $ 0.31125/oz
Given data ,
To determine the best price per ounce for Dairy Queen blizzards, we can calculate the cost per ounce for each size option:
Small: 6 oz. for $2.49 ->
Cost per ounce = $2.49 / 6 oz. = $0.415/oz.
Large: 16 oz. for $4.98 ->
On simplifying the equation , we get
Cost per ounce = $4.98 / 16 oz. = $ 0.31125/oz.
Medium: 10 oz. for $3.49 ->
Cost per ounce = $3.49 / 10 oz. = $0.349/oz.
Super Size: 24 oz. for $7.69 ->
On simplifying the equation , we get
Cost per ounce = $7.69 / 24 oz. = $0.32042/oz.
Comparing the cost per ounce for each size option, we can see that the Small blizzard has the highest cost per ounce at $0.415/oz. The Large blizzard has the lowest cost per ounce at $ 0.31125/oz.
Hence , the Large blizzard gives you the best price per ounce among the options provided.
