In triangle ABC, if angle A measures 78° and angle B measures 63º, what is the measure of angle C?
Answer:
∠C=39°
Step-by-step explanation:
The interior angles of a triangle will always have a sum of 180°.
∠A+∠B+∠C=180°
78°+63°+∠C=180°
∠C=180°-78°-63°
∠C=39°
Answer:
39 degrees
Step-by-step explanation:
All triangles will add up to 180 degrees. So, you know that angle C added with angles A and B will equal 180. if you take 180, minus 78, minus 63, you get the answer 39.
Choose the law and the formula that would be used to solve the triangle.
Answer: A^2
Step-by-step explanation:
Angle C + Angle B = Angle A

Answer:
70°
Step-by-step explanation:
In the context it says that Franklin St. is parallel to Washington St.
The 110° formed by Franklin St. and Mulberry St. is a supplementary angle to Angle x.
Supplementary angles are angles that add up to each other to make 180°
So lets subtract:
180 - 110 = 70°
Angle x = 70°

A high school soccer team is going to Columbus to see a professional soccer game. A coordinate grid is superimposed on a highway map of Ohio. The high school is at point (3, 4) and the stadium in Columbus is at point (7, 1). The map shows a highway rest stop halfway between the cities. What are the coordinates of the rest stop? What is the approximate distance between the high school and the stadium? (One unit = 6.4 miles.)
Answer:
a) The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].
b) The approximate distance between the high school and the stadium is 32 miles.
Step-by-step explanation:
a) The rest stop is located in the midpoint of the line segment between the high school and the stadium. Vectorially speaking, we use the following formula:
[tex]C(x,y) = \frac{1}{2}\cdot A(x,y) + \frac{1}{2}\cdot B(x,y)[/tex] (1)
Where:
[tex]A(x,y)[/tex] - Coordinates of the high school.
[tex]B(x,y)[/tex] - Coordinates of the stadium.
[tex]C(x,y)[/tex] - Coordinates of the rest stop.
If we know that [tex]A(x,y) = (3, 4)[/tex] and [tex]B(x,y) = (7,1)[/tex], then the coordinates of the rest stop are, respectively:
[tex]C(x,y) = \frac{1}{2}\cdot (3, 4) + \frac{1}{2}\cdot (7, 1)[/tex]
[tex]C(x,y) = \left(\frac{3}{2}, 2 \right) + \left(\frac{7}{2}, \frac{1}{2} \right)[/tex]
[tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex]
The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].
b) The approximate distance between the high school and the stadium ([tex]d[/tex]), in miles, is the product of the Length Equation of the Line Segment and the scale factor:
[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex] (2)
Where:
[tex]r[/tex] - Scale factor, in miles.
[tex]\Delta x[/tex], [tex]\Delta y[/tex] - Horizontal and vertical distances between the high school and the stadium, no unit.
If we know that [tex]r = 6.4\,mi[/tex], [tex]\Delta x = 4[/tex] and [tex]\Delta y = -3[/tex], then the distance between the high school and the stadium is:
[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex]
[tex]d = (6.4\,mi)\cdot \sqrt{4^{2}+(-3)^{2}}[/tex]
[tex]d = 32\,mi[/tex]
The approximate distance between the high school and the stadium is 32 miles.
Why does the equation 5(3x-4)-6x=3(3x-4) have no solutions?
Bureause when you subtract from both sides of the equation and simplify you get 20-20
Berise when you add to both sides of the equation and simplify you get = -12
Because when you add to both sides of the equation and simplify you get 2020
Because when you add-to both sides of the equation and simple you get 20-12

The recipe for a large batch of cookies uses 1 kilogram of flour. Another recipe uses 700 grams of flour. How much flour is needed to make two batches of each recipe?
1 kilogram = 1,000 grams
Answer:
3,400 grams
Step-by-step explanation:
The total amount of flour needed to make two batches of each recipe is 3400 grams.
How much gram is equal to 1 kilogram?1000 grams is equal to 1 kilogram.
Amount of flour used in one batch of the first recipe= 1 kilogram
So, the amount of flour used in two batches of the first recipe=2 kilogram =2000 grams.
Amount of flour used in one batch of the second recipe= 700 grams
So, the amount of flour used in two batches of the second recipe= 2*700=1400 grams.
Total amount of flour needed = 2000+1400 =3400 grams.
Hence, The total amount of flour needed to make two batches of each recipe is 3400 grams.

A coach buys a jersey and a team cup for each of the 10 players on the basketball team. Each team cup costs $16. The coach spends a total of $296 for the jerseys and team cups. Enter an equation that models the situation with u, the cost of one jersey.
please someone explain
Answer:
Cost of each jersey = $13.6
Step-by-step explanation:
Given:
Cost of each team cup = $16
Total amount spend = $296
Total number of team cup = 10
Total number of jersey = 10
Find:
Cost of each jersey
Computation:
Assume;
Cost of each jersey = c
So,
16(10) + (c)(10) = 296
160 + 10c = 296
10c = 296 - 160
10c = 136
c = 136 / 10
Cost of each jersey = $13.6

7x + 6y = -1 ; -x + 2y = 3 with elimination
Answer:
x= -1, y=1
Step-by-step explanation:
First label the 2 equations.
7x +6y= -1 -----(1)
-x +2y= 3 -----(2)
Then choose which term you would like to eliminate. To eliminate the y term, multiply equation (2) by 3 such that the coefficient of y is 6.
(2) ×3:
-3x +6y= 9 -----(3)
Since the coefficient of y is positive 6 in both equations, subtract one equation from the other.
(3) -(1):
-3x +6y -(7x +6y)= 9 -(-1)
Expand:
-3x +6y -7x -6y= 9 +1
-10x= 10
x= 10 ÷(-10)
x= -1
Substitute x= -1 into (2):
-(-1) +2y= 3
1 +2y= 3
2y= 3 -1
2y= 2
y= 2 ÷2
y= 1
------------------------------------------------------------
2nd method: eliminating the x term
(2) ×7:
-7x +14y= 21 -----(3)
Since the coefficient of y in equation (1) is a positive 7, while that in equation (3) is a negative 7, add the 2 equations together to eliminate the x term.
(1) +(3):
7x +6y -7x +14y= -1 +21
20y= 20
y= 20 ÷20
y= 1
Substitute y= 1 into (2):
-x +2(1)= 3
-x +2= 3
-x= 3 -2
-x= 1
x= -1

Jorge has a swimming pool that is rectangular in shape. The length and width of the pool are 24 feet and 14 feet. He also knows that the pool has a consistent depth of 5 feet. He needs to add 4 drops of chlorine for every 50 cubic feet in his pool. How many drops of chlorine should Jorge use to chlorinate his pool properly?
Answer:
140 drops
Step-by-step explanation:
Length of the pool = 24 feet
Width of the pool = 14 feet
Depth of the pool = 5 feet
Volume of the pool = length × width × depth
= 24 ft * 14 ft * 5 ft
= 1,750 ft³
Volume of the pool = 1,750 ft³
He needs to add 4 drops of chlorine for every 50 cubic feet in his pool.
Number of 50 cubic feet in the volume of the pool = Volume of the pool / 50 ft³
= 1,750 ft³ / 50 ft³
= 35
Number of 50 cubic feet in the volume of the pool = 35
How many drops of chlorine should Jorge use to chlorinate his pool properly?
Number of drops of chlorine Jorge should use = number of drops per 50 ft³ × Number of 50 cubic feet in the volume of the pool
= 4 × 35
= 140 drops
Number of drops of chlorine Jorge should use = 140 drops
Find the volume of a pyramid with a square base, where the area of the base is 6.8m^2
and the height of the pyramid is 8.6. Round your answer to the nearest tenth of a cubic meter.
Answer:
[tex]19.5\:\mathrm{m^3}[/tex]
Step-by-step explanation:
The volume of a square pyramid is given by [tex]V=\frac{1}{3}\cdot s^2\cdot h[/tex], where [tex]s[/tex] is the base edge and [tex]h[/tex] is the height. Since the base area ([tex]s^2[/tex]) is already given to us, we can substitute directly in to our equation.
Solving for [tex]V[/tex]:
[tex]V=\frac{1}{3}\cdot 6.8\cdot 8.6\approx \boxed{19.5\:\mathrm{m^3}}[/tex]
