Maria plans to make a triangular center island along the road. The said plan is illustrated at the image attached. She was able to put a fence around the lot which measures LT = 3m and OL = 3m. The said land area is an example of an oblique triangle which does not contain any right angle. If m∠T = 70 and m∠L = 65, what could be the measurement of ∠O and TO (round off to the nearest whole number)?
WITH SOLUTION!!!
The sum of interior angles of triangle sum up to 180°
Hence,
∠O + 70° + 65° = 180°
∠O = 180° - 65° - 70°
∠O = 45°
∴ The angle ∠O is 45 degrees.
To find length of TOUse cosine rule: a² = b² + c² - 2bc cos(A)
Hence,
TO² = 3² + 3² - 2(3)(3) cos(65)
TO² = 10.39287129
To = √10.4
TO = 3.22 ≈ 3 meters (rounded to nearest whole number)
∴ The length of TO is 3 meters.
Use circle E to answer the following questions
Based on the circle theorems, the measures in circle E are:
m(AB) = 40°
m∠AEB = 40°
m∠ACB = 40°
m(ADB) = 320°
What are the Circle Theorems?The theorems are:
Measure of the central angle = measure of intercepted arcMeasure of inscribed angle =1/2( measure of intercepted arc)Measure of inscribed angles with same intercepted arcs are congruent.Using the circle theorems, given the inscribed angle, m∠ADB = 20°, we have:
m(AB) = 2(m∠ADB) = 2(20) = 40°
m∠AEB = m(AB) = 40°
m∠ACB = m∠AEB = m(AB) = 40°
m(ADB) = 360° - 40° = 320°

Answer:
6.08
Step-by-step explanation:
For four brushes its 16 and for two rollers and trays its 16. Add that with the tax and you’ll get 33.92. Subtract 40 with the overall cost to get 6.08
Answer:
$6.08
Step-by-step explanation:
To find the change you must add together the cost of all the items and the tax. then subtract that by 40 dollars
So . .
Painbrushes cost $4.00
$4.00 × $4.00 = $16.00Rollers cost $8.00
$8.00 × 2 = $16.00Add them
$16.00 + $16.00 = $32.00Then Add $1.92 to $32.00$33.92Then Subtract that from $40.00
So. .
$40.00 - $33.92= $6.08
How to find slope and slope intercept form and slopes of perpendicular and parallel and point-slope form
Answer:
Parallel lines have the same slope, so in y = mx +b, m would have the same value for both.
In perpendicular lines, the value of the m is inversed. Because the m is over an invisible one in this case, m/1(x) becomes -1/m(x), making the equation y = 1/m(x) + b
Point-slope form is (y - y1) = m (x - x1), meaning that the first term of y subtracted from the zeroth term of y is equivalent to m multiplied by the value of the first term of x from the zeroth term of x

Find the equation of the circle with center (4,5) which passes through the y-intercept of the line 5x-2y+6=0
Answer:
(x-4)^2 + (y-5)^2 = 20
Step-by-step explanation:
Rearrange the line equation of 5x - 2y + 6 = 0
So y = 5/2x +3
The y-intercept of the line equation is 3 as when x=0, y=3.
We know the Circle has the formula [tex](x-4)^2 + (y-5)^2 = ?^2[/tex] from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:
[tex](0-4)^2 + (3-5)^2 = ?^2[/tex]
This simplifies to:
[tex](-4)^2 +(-2)^2[/tex] = [tex]?^2[/tex]
16 + 4 = 20 = [tex]?^2[/tex]
The answer is 20 so the equation of the circle is [tex](x-4)^2 + (y-5)^2 = 20[/tex]
Which equation represents the line that passes through the points (-4, 4) and (8, -2) ?
Answer:
There fore the answer is y=(-1/2)x +2
Step-by-step explanation:
Find straight line question passing through the points (-4,4) and (8,2)
Use formula (y-y1) (x2-X1) = (y2-V1) (x-x1)
(y-Y1) (x2-X1) = (y2-Y1)(x-x1)
Substitute points in formula
(y-4)(8+4) = (-2-4) (x+4)
(y-4)12=-6(x+4)
y-4=(-1/2) (x)-(2)
y=(-1/2)x-2+4
y=(-1/2)x +2

Answer:
7.07 years
Step-by-step explanation:
The standard deviation of a population is easily calculated by a spreadsheet or calculator. Care must be taken to use the formula for population standard deviation, rather than the formula that assumes the values are a sample.
__
The attached calculator shows the standard deviation is about 7.07 years.
_____
Additional comment
The population standard deviation is the square root of the variance. The variance is the mean of the squares of the values, less the square of the mean of the values. The second attachment shows the calculation done this way.
The units of standard deviation are the same as the units of the members of the population. Here, that is "years."

A a right triangle has a hypotenuse length of 21 meters. It has
one leg with a length of 15 meters. What is the length of the other leg?
Express your answer as a square root.
Answer:
√216 meters
Step-by-step explanation:
» Concepts
The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs is equal to the length of the hypotenuse squared. It's represented as an equation of a² + b² = c², where a & b are the legs, and c is the hypotenuse
» Application
To find the length of the other leg, we have to plug in the values of b and c into the equation. B would be 15 meters, and c would 21 meters.
» Solution
Step 1: Simplify both sides of the equation.
[tex]a^2+15^2+21^2[/tex] [tex]a^2+225=441[/tex]Step 2: Subtract 225 from both sides.
[tex]a^2+225-225=441-225[/tex] [tex]a^2=216[/tex]Step 3: Take square root of both sides.
[tex]\sqrt{a^2} = \sqrt{216}[/tex] [tex]a = \sqrt{216}[/tex]Therefore, the length of the other leg is √216 meters.

In one week my brother's daily expense for his lunch are Birr 54, Birr 61, Birr 42, Birr 63, Birr 42, Birr 56, and Birr 58. what
is his mean daily expense?
Answer:
The mean expense is approximately equal to 53.714
Step-by-step explanation:
When you are trying to find the mean of a number set, you are trying to find the average of the stats. As such, use the formula Sum of the Numbers / Total Number of Values.
In this case, we are adding 54 + 61 + 42 + 63 + 42 + 56 + 58, which is equal to 376. We are then dividing this by 7, which is equal to about 53.714.

The exchange rate of US dollars to Polish zloty is 1:3.1264. The correct option is b. 1:3.1264
Calculating exchange ratesFrom the question, we are to determine the exchange rate of US dollars to Polish zloty
From the given information,
Gary exchanged US dollars for Euros at a rate of 1:0.7716
That is,
1 US dollar = 0.7716 Euros
Also, he exchanged Euros for Polish zloty at a rate of 1:4.0518
That is,
1 Euro = 4.0518 Polish zloty
Now, we will find the value of 0.7716 Euros in Polish zloty
Since 1 Euro = 4.0518 Polish zloty
Then,
0.7716 Euro = 0.7716 × 4.0518 Polish zloty
∴ 0.7716 Euro = 3.1264 Polish zloty
But
1 US dollar = 0.7716 Euros
Therefore,
1 US dollar = 3.1264 Polish zloty
Hence, the exchange rate of US dollars to Polish zloty is 1:3.1264. The correct option is b. 1:3.1264

27.9% of 43 + 39.5% of 43 + 32.6% are black = 100%
There is the highest chance that the jelly beans chosen will be white, with black following. 2 white & 3 black would be 5/43 which is 11.6% of the jelly beans in total. Of this chance there is about a 25% chance that white will be chose & 27-30% chance that black will be chosen.

Step-by-step explanation:
since there is a 10/30 chance
to simplify divide by 2
10/30 ÷ 2/2 = 5/15
then divide by 5
5/15 ÷ 5/5 = 1/3
your answer is 1/3
another simple way to simplify
since there is a zero (0) in both the ones (1s) spot on both the numerator and denominator in 10/30, you may just cross out both zeros (0s) to simplify the value
