Answer:
35 degrees
Step-by-step explanation:
for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?
Let the given expression be equal to 1, hence;
csc (2x+30°)= cos (3y-15°) = 1
csc (2x+30°) = 1
1/sin(2x+30) = 1
1 = sin(2x+30)
sin(2x+30) = 1
2x+30 = arcsin(1)
2x+30 = 90
2x = 90-30
2x = 60
x = 60/2
x = 30 degrees
Get the value of y;
cos (3y-15°) = 1
3y - 15 = arccos (1)
3y - 15= 0
3y = 0+15
3y = 15
y = 15/3
y = 5
Sum of x and y;
x+y = 30 + 5
x+y = 35degrees
Hence the sum of x and y is 35 degrees
Halla dos números naturales tales que su suma sea 154,y su cociente, 8/3

An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+a-27.2=180
2a-27.2=180
2a=207.2
a=103.6, and since b=a-27.2
b=76.4
So one angle is 103.6 degrees and the other is 76.4 degrees.
La finca de Federico tiene tiene un área de 576 m2, En ella ha sembrado naranja y café, 3/8 de la finca están sembrados de naranjas y el resto de café, ¿Cuál es el área de la finca que están sembrada por café?
Answer:
El área de la finca que está sembrada por café es 360 m².
Step-by-step explanation:
La finca de Federico tiene tiene un área de 576 m². [tex]\frac{3}{8}[/tex] de la finca están sembrados de naranjas. Entonces, el área de la finca que está sembrada por naranjas se calcula mediante:
576 m²* [tex]\frac{3}{8}[/tex] = 216 m²
Sabiendo que el resto de la finca esta sembrada de café, esta área se calcula mediante la diferencia del área total de la finca y el área sembrada por naranjas:
576 m² - 216 m²= 360 m²
El área de la finca que está sembrada por café es 360 m².

Step-by-step explanation:
Hope this helps! :3
Answer:
(0, 19)
Step-by-step explanation:
Find the equation.
Find the slope:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
22-16/1-(-1) = 6/2 = 3
Here's our equation so far:
y = 3x + b
Find b by plugging in one pair of (x,y) coordinates.
22 = 3(1) + b
22 = 3 + b
b = 19
Now we now the equation:
y = 3x + 19
So, the y-intercept is 19.
Mhanifa please help! Explain how you can use the perpendicular bisector of a segment to draw an isosceles triangle.
Answer:
If you construct the perpendicular bisector of a line segment, every point on the perpendicular bisector will be the same distance from both point A and point B.
To construct an isosceles triangle, you can start from any point on the perpendicular bisector and draw line segments to point A and to point B
The required steps are in the solution that to use the perpendicular bisector of a segment to draw an isosceles triangle.
What is an isosceles triangle?An isosceles triangle is defined as a triangle with two sides of equal length.
To use the perpendicular bisector of a segment to draw an isosceles triangle, you can follow these steps:
Draw the segment for which you want to find the perpendicular bisector.
Use a compass to draw a circle with its center at the midpoint of the segment.
With the compass still set to the same radius, draw two arcs that intersect the segment at two points. These points will be the base points of the isosceles triangle.
Draw a line through the midpoint of the segment and the point where the arcs intersect the segment. This line is the perpendicular bisector of the segment.
Use a ruler to draw a line segment connecting the base points of the isosceles triangle.
Use a ruler to draw a line segment connecting the apex of the isosceles triangle (the point where the perpendicular bisector intersects the base) to one of the base points.
At this point, you should have a triangle with two equal sides and a right angle at the apex. This is an isosceles triangle.

Evaluate the following expression.
2 + (3 – 2 x 2) x 1
Answer:
Step-by-step explanation:
2 + (3 – 2 x 2) x 1
This is what I remember, but you need to check this order of arithmetic operations.
Parentheses first then exponents ( you don't have any) multiplication and division left to right and then addition and subtraction again left to right
2 + (3 – 2 x 2) x 1 so 3 – 2 x 2 equals 3 - 4 which equaltes to
2 + (-1) x 1 -1 x 1 = -1
2 + (-1) x 1 is to clearer to me than 2 + -1 x 1 maybe not
2 + -1

Find the probability that a randomly selected point within the circle falls in the white area
Answer:
Step-by-step explanation:
The white area is the area of the circle minus the area of the triangle.
Aw=pr^2-hb/2
Aw=p4^2-6.5(6)/2
Aw=16p-19.5
The probability of selecting the white area is the white area divided by the area of the circle
P(W)=(16p-19.5)/(16p), p=3.14
P(W)=0.61
pam is 17 years old and her sister is 9. her two brothers are 11 and 7 years old. what is the mean of their ages
Answer:
11
Step-by-step explanation:
17+9+11+7 divided by 4
because the mean= sum of the terms divided by the number of terms
the sum= 17+9+11+7=44
the number of terms= 4
44 divided by 4= 11
Answer:
(17+9+11+7) / 4 mean is an average
it is equal to the sum of the elements divided by the number of elements
the sum is 44
the number of elements is 4
the mean is the average= 44/4=11

What is the slope of the line that passes through the points (5,−4) and (7, -4) ?Write your answer in simplest form.
Answer:
Undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
[tex] =\frac{ - 4 - ( - 4)}{7 - 5} \\ =\frac{ - 4 + 4}{2} \\ = \frac{0}{2} \\ (undefined)[/tex]
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.

Answer:
Answer:
Mass of a bouquet = v + 3d + 4t
Step-by-step explanation:
Mass of daffodil = d gm
Mass of Tulip = t gm
Mass of vase = v gm
Mass of a bouquet = mass of vase + Mass of 3 daffodils + Mass of 4 tulips
=> Mass of a bouquet = v + 3d + 4t
Flower bouquet weight = v + 3d + 4t

Answer:
Answer 1. 3in
Answer 2. 0.875in
Answer 3. 26 miles
Answer 4. 7.67in
Step-by-step explanation:
Answer 1. We know that 2 feet in real life is going to equal 1 inch, so since the person is 6 feet, we divide that by 2 to get 3. So the action figure is going to be 3in.
Answer 2. In this case, we see that 1 foot is equal to four inches. That must mean that 1 inch is equal to a quarter foot. So we just multiply
0.25 x 3.5 = 0.875
The length is 0.875 feet
Answer 3.
We know that 1 inch = 6.5 miles, and there are 4 inches on the map, so we have to multiply 6.5 x 4 to find out how many miles there is.
Answer 4.
To find this one out, we have to divide 9 into 69. That gives us 7.67. So 69 nautical miles would be equal to 7.67 inches on the map

Ind the volume of a pyramid with a square base, where the side length of the base is 15.3\text{ m}15.3 m and the height of the pyramid is 19.6\text{ m}19.6 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
1,487.3m³
Step-by-step explanation:
Volume of a square based pyramid is expressed as;
V = BH/3
B is the base area
H is the height of the pyramid
Since the side length of the base is 15.3m;
Base area = L²
Base area = 15.3²
Base area = 234.09m²
Height of pyramid = 19.6m²
Get the volume
Volume of the square based pyramid = (234.09*19.6)/3
Volume of the square based pyramid =1,487.3m³ (to the nearest tenth)

Toni bought 5 t-shirts for 35 if each T-shirt cost the same amount .how much tony would pay for20 shirts 
Answer: The answer is Toni can buy 20 tee shirts for 140 dollars
Step-by-step explanation:
First you find out how many times 5 can go into 20
Next you see that 5 can go into 20, 4 times so you take the 35 and multiply 4 and you get 140 so you can buy 20 tee shirts for 140 dollars.
If EBCD is a parallelogram, EB = 16, ED = 25, BF = 11, EC = 34, mZBED = 55°, mZCDB = 67°,

Answer:
1. BC = 25
2. m∠EDC = 125°
3) BD = 22
4) m∠EBD = 67°
5) FC = 17
6) m∠BEC = 24°
7) CD = 16
8) m∠DBC = 58°
Step-by-step explanation:
The dimensions of parallelogram EBCD are;
EB = 16, ED = 25, BF = 11, EC = 34, m∠BED = 55°, m∠CDB = 67°
1. BC = ED = 25 Opposite sides of a parallelogram are equal
2. m∠BCD = m∠BED = 55 opposite angles of a parallelogram are equal
m∠BCD + mEDC = 180° adjacent sides of a parallelogram are supplementary
m∠EDC = 180° - m∠BCD
∴ m∠EDC = 180° - 55° = 125°
m∠EDC = 125°
3) BD = BF × 2 Diagonals of a parallelogram bisect each other
∴ BD = 11 × 2 = 22
BD = 22
4) m∠EBD = m∠CDB = 67° from alternate angles between parallel lines
5) FC = EC/2 from diagonals of a parallelogram bisect each other
∴ FC = EC/2 = 34/2 = 17
FC = 17
6) m∠BEC = m∠BCE = 24° Alternate angles between parallel lines
m∠BEC = 24°
7) CD = EB = 16 Opposite sides of a parallelogram are equal
8) m∠EBC = m∠EDC = 125° from opposite angles of a parallelogram are equal
m∠DBC + m∠EBD = m∠EBC from angle addition postulate
∴ m∠DBC = m∠EBC - m∠EBD
m∠DBC = 125° - 67° = 58°
m∠DBC = 58°
