The measure of an angle is 23°. What is the measure of its supplementary angle?
Answer:
If one angle is 23 then the other is 180-23 = 157
one angle is the supplementary of other
23 is the supplementary of 157
157 is the supplementary of 23

whats the answer to this? (with an explanation please)
Answer:
Step-by-step explanation:
no of yellow marbles = 6
no. of green marbles = 6
total no. of marbles = 12
he picks and put the marbles for 26 times
he pick yellow for 15 times
he pick green marble for 11 times
= (15/26 - 1/2) / 1/2 = 15.4%
Tyler has to figure out the amount of metal to cover the back of the shelves in Mrs. Edwards room. These are the dimensions. What is the amount of metal he will need to cover the back of the shelves?
210 square inches
108 square inches
180 square inches
36 square inches
The amount of metal he will need to cover the back of the shelves is 180 inches².
The figure above is like a composite figure. Therefore, lets find the area.
Area of the composite figureThe area of the figure is the sum of the whole individual 2 dimensional shapes in the composite figure.
Therefore, two rectangles can be drawn from it.
area of rectangle = lw
where
l = length
w = width
Therefore,
area of rectangle 1 = 9 × 8 = 72 inches²
area of rectangle 2 = 6 × 18 = 108 inches²
Total area = 108 + 72 = 180 inches²
Therefore, the amount of metal he will need to cover the back of the shelves is 180 inches².

Ms. Gonzales gathered data on the number of vowels in the first and last names of each of her students. The data are shown in the dot plot.
Vowels in student names. Number of vowels.
What percentage of the students have 5 or more vowels in their first and last names?
From the dot plot, we have that 90.91% of the students have 5 or more vowels in their first and last names.
---------------------
The dot plot states that:
2 students have 4 vowels in their first and last name.
3 students have 5 vowels.
8 students have 6 vowels.
9 students have 7 vowels.
Then:
Total of 2 + 3 + 8 + 9 = 22 students.
3 + 8 + 9 = 20 have or more vowels.
90.91% of the students have 5 or more vowels in their first and last names.

So
P(AUB)=P(A)+P(B)
P(AUB)=62+34=96Please help with factor trees, if u click here there will be the question
Answer:
Spot 1: 14
Spot 2: 7
Step-by-step explanation:
To fill in the first empty spot, we just have to look at the other side.
We can see that the factor on the right is 4
That means the factor on the left has to multiply by 4 to get 56
To find which number that is, we divide 56 by 4
56 ÷ 4 = 14
So, the first spot is 14
Then, to find the spot below it, we need a number that multiplies by 2 to get 14
Well, 14 ÷ 2 = 7
The second spot is 7
The scale model of a car is 5% of the size of the actual car. The length of
the model is 9 inches. How many feet long is the actual car?
Explanation:
x = length of the actual car in inches
5% of x = 9 inches
0.05x = 9
x = 9/(0.05)
x = 180 inches
Divide by 12 to convert from inches to feet.
180 inches = (180/12) feet = 15 feet
algebra fraction thing!!! pls explain I'm so lost??? like I don't see why the answer isn't 2n-2? did my teacher make a mistake or am I missing something?
Answer:
a.
Step-by-step explanation:
[tex] \frac{n - 9}{2n - 5} + \frac{3n - 1}{2n - 5} [/tex]
Since the denomaitor is the same, just add straight across.
[tex] \frac{4n - 10}{2n - 5} [/tex]
The numerator can be factored.
The greater common factor is 2 so we have
[tex] \frac{2(2n - 5)}{2n - 5} [/tex]
Notice that the numerator and denomiator are the same.
This means they will divide out to 1 so we have

Mary and Vincent climbed up a rock wall at the park, Mary climbed 3/4 the way up the wall, Vincent climbed 3/8 of the way up the wall, who climbed higher
Answer:
Mary
Step-by-step explanation:
You have to change the fractions so that the denominator is the same in both of them. To do this, you can multiply the numerator and denominator in 3/4 by 2. This would equal 6/8.
6/8 > 3/8
This shows that Mary climbed higher.

Use the properties of logarithms to expand the logarithm as much as possible. Rewrite the expression as a sum, difference, or product of logs.
log(x3y−8−−−−−−√)
Answer:
You are multiplying two factors in the argument. So we add the logs.
log(x4y3) + log((x2y5)1/3)
log(x4y3) + log(x2/3y5/3)
For each log term. The arguments are being multiplied. So we further add the logs. Also, any exponents become of the coefficients of logs.
4log(x) + 3log(y) + (2/3)log(x) + (5/3)log(y)
Combine like log terms.
(14/3)log(x) + (14/3)log(y)
Hope it helps!!!!!!brainliest pls!!!!!!Which inequality matches the graph shown below? y < -2x-1, y > -2x-1, y > 2x-1, y < 2x-1
Answer:
y > 2x - 1
Step-by-step explanation:
the first thing we see in the graph is the dotted line. so, the line itself will not be included. therefore, no "<=" or ">=", but there was none in the answer options anyway.
then we see the shaded area is "above" (in tendency) the line. so, we are talking about a "y > ..." inequality.
then we see the y-intercept (the y value when x=0). it is -1, but all the answer options have "-1" as y-intercept. OK.
and then we see the slope of the line. when checking after (0, -1) the next point on the line with whole numbers as coordinates, we find (1, 1). so, while x increased by 1, y increases by 2. so, the slow is "y change"/"x change" = 2/1 = 2
so, in total, we are looking for the line
y = 2x - 1
and to cover the whole area above the line (but without the line) we get then
y > 2x - 1

2. A father offers three portions of his crop land to his daughter for a corn maze. All
portions are circular and the daughter can only choose one portion. The first
portion has an 875 feet radius. The second portion has a 1715 feet diameter. The
third portion has a 5305 feet circumference. The daughter does not want more
than 2,250,000 square feet of corn maze. Which of the portions will be chosen by
the daughter?
If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions
Circumference and area of circlesThe formula for calculating the area of circle is expressed as;
A = πr²
r is the radius of the circle
If r = 875ft
A = 3.14(875)²
A = 2,404,062.5squar feet
For the diameter = 1715feet
r = 1715/2
A = 3.14(1715/2)²
A =2,308,861.625 square feet
For the third portion has a 5305 feet circumference;
5305 = 2(3.14)r
r = 844.74ft
A = 3.14(844.74)^2
A = 2,240,686.70
If the daughter does not want more than 2,250,000 square feet of the corn maze, hence she will choose all the portions

Answer:

Answer:
Step-by-step explanation:
in 10 hrs distance covered=speed×time=15×10=150 nautical miles.
x²=600²+150²-2×600×150×cos 20°
x²=360,000+22,500-180,000×cos 20°
x=√(382,500+180,000×cos 20°)
x\approx 742.73 nautical miles
time taken=742.73/15 \approx ~49.52 hours
total time taken=10+49.52=59.52 hours
applying sine formula
[tex]\frac{sin ~B}{150} =\frac{sin~20}{742.73} \\\sin~B=\frac{150}{742.73} \times~sin~20\\B=\sin^{-1} [\frac{150}{742.73} \times \sin~20]\\B\approx~3.96 ^\circ\\B\approx 4^\circ[/tex]
