Answer:
∠A = 90
∠B = 30
∠C = 60
Step-by-step explanation:
Let ∠B = x
∠A = 3x
∠C = x + 30
Angle sum property of triangle: Sum of three angles of triangle is 180
x + 3x + x + 30 = 180 {Combine like terms}
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 130/5
x = 30
∠A = 3*30 = 90
∠C = 30 + 30 = 60

The formula B = 2HL can be used to determine the number of bricks, B, needed to build a wall of height H and length L.
What is the height of a wall built 28 feet long and requires 1736 bricks?
Answers
9514 1404 393
Answer:
31 feet
Step-by-step explanation:
Fill in the given numbers and solve for the missing value.
B = 2HL
1736 = 2H(28)
1736/56 = H = 31
The wall is 31 feet high.
Answer:
N = 7·L·H
2310 = 7·30·H
2310 = 210·H (now, divide both sides by 210)
2310 ÷ 210 = 11
H = 11 feet

Second You would put them in the slope formula y2-y1/x2-x1
Third You would want to solve the formula by getting 2-0 and 7-1 And get 6/2
Fourth Simply 6/2 and get 3/1 which is also 3.

LaTanya will walk (3 mi/hr) her bike from her house to the
bike shop, which is 1.5 mi from her house, to get the bike
fixed. She expects to wait 30 min for the repair. Then she
will ride (10 mi/hr) her bike home. How long will it take
her to get home?
A)2.12 hr
B)2hr
C)1.15
D)4hr
Answers
Answer:
1.15 hr
Step-by-step explanation:
Given that:
To get bike fixed :
Speed = 3 miles per hour
Distance = 1.5 miles
Time taken = distance / speed
Time taken = 1.5 / 3 = 0.5 hour
Waiting time for repair = 30 minutes = 0.5 hours
Return home :
Speed = 10 miles per hour
Distance = 1.5 miles
Time taken = distance / speed
Time taken = 1.5 / 10 = 0.15 hour
Total time : (0.5 + 0.5 + 0.15) = 1.15 hr

Answer:
(0, 5), (10, 0)
Step-by-step explanation:
It can be useful to graph the equation and plot the points. Alternatively, you can evaluate the equation at the offered points.
Right away, you will notice that x must be even if y is to be an integer. The first point is the y-intercept, which the equation tells you is (0, 5). Then the only remaining candidate point is (10, 0), which also satisfies the equation:
0 = (-1/2)(10) +5 = -5 +5

Why will the lines never intersect?
y = -x +5
y=-x-3
Answers
Answer:
The lines never intersect because the lines are parallel.
Step-by-step explanation:
Given system of linear equations is:
y = -x +5
y=-x-3
The slope-intercept form of a line is:
[tex]y = mx+b[/tex]
Here b is the y-intercept and the co-efficient of x is the slope of the line
Comparing the given equations with slope intercept form we get that the slope of both lines is -1
Both lines have the equal slope which means that the lines are parallel.
Parallel lines NEVER intersect each other.
Hence,
The lines never intersect because the lines are parallel.

what is the solution set of this inequality? 1<|x-2|<5
(-3, ) U ( , )
Answers
We first need to consider the absolute value of x-2 to find the solution set of this inequality, The solution set of this inequality is (3, 4, 5).
What is absolute value?An absolute value is a number's distance from 0 on the number line.
Since the inequality is 1<|x-2|<5, we can then determine the two extreme points of the absolute value of x-2.
These points are 1 and 5.
Now, to find the solution set of this inequality, we need to find the two points that are 1 and 5 units away from the point x = 2.
The two points that are 1 and 5 units away from x = 2 are 3 and 5 respectively.
This is because the absolute value of x-2 has two extreme points, which are 1 and 5 units away from the point x = 2.
Therefore, the two points that are 1 and 5 units away from x = 2 are 3 and 5 respectively.

what is the equation of the line that passes through the point (4,7) and has a slope of o?
Answers
Answer:
The equation of the line that passes through the point (4,7) and has a slope of 0 will be:
[tex]y=7[/tex]Step-by-step explanation:
As we know the equation of a line in a slope-intercept form of an equation is
[tex]y = mx + b[/tex]
Here,
m is the slopb is the y-interceptso
substituting the point (4,7) and slope m=0
[tex]y = mx + b[/tex]
[tex]7=0(4)+b[/tex]
[tex]7=0+b[/tex]
[tex]b=7[/tex]
Therefore, the equation of the line that passes through the point (4,7) and has a slope of 0 will be:

Step-by-step explanation:
Nate tosses a ball up a hill for his dog to chase. The path of the ball is modeled by the function y=- 1 4 x^ 2 + 33 5 x. , where x is the ball's horizontal distance from Nate in feet and y is the ball's height in feet. The hill is modeled by the line y = 1/5 * x . How far does the ball travel horizontally before it hits the ground? (in feet, round to tenth place if necessary )
Answers
Answer:
The ball's horizontal distance from Nate in feet when the ball hits the ground is 25.6 feet
Step-by-step explanation:
The given equation that represents the path of the ball is y = -1/4·x² + 33/5·x
The equation of the that models the hill is y = 1/5 × x = 1/5·x
Where, x represents the ball's horizontal distance from Nate in feet and y represents the ball's height in feet
To find the point of contact, we equate both equations to find the common solutions as follows;
-1/4·x² + 33/5·x = 1/5·x
-1/4·x² + 33/5·x - 1/5·x = -1/4·x² + 32/5·x = 0
-1/4·x² + 32/5·x = 0
0 = 1/4·x² - 32/5·x
1/4·x² - 32/5·x = 0
x·(1/4·x - 32/5) = 0
x = 0 or 1/4·x - 32/5, and x = 32/5 × 4 = 128/5 = 25.6
The ball's horizontal distance from Nate in feet = x = 25.6 feet
The ball's horizontal distance from Nate in feet when the ball hits the ground is 25.6 feet.
