Answer:
77.5 degrees and 102.5 degrees
Step-by-step explanation:
Given that : one angle is25 degrees greater than another. Let the two angles be represented by a and b. Since one angle is 25 degreess greater than another, then:
b = a + 25 degrees
But;
a + b = 180 degrees (sum of angles on a straight line)
a + a + 25 degrees = 180 degrees
2a = 180 degrees - 25 degrees
a = 77.5 degrees
b = 77.5 degrees + 25 degrees = 102.5 degrees
Therefore the measures of all angles formed by the lines is either 77.5 degrees or 102.5 degrees.

Answer:
51/200.
Step-by-step explanation:
hope this helps
Answer:
51/20 or 2 11/20
Step-by-step explanation:
We know that percentages are fractions out of 100, so, our original fraction would be:
255/100
both of these numbers can be divided by 5, so:
255 ÷ 5 = 51
100 ÷ 5 = 20
51/20
This can also be turned into a mixed number, so:
2 11/20

$70.00 at 5% for 2 years
Answer:
$7
Step-by-step explanation:
Hey there
to solve this kind of problem we use the formula:
[tex]\frac{p * t * r}{100}[/tex] if we solve it :First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 70 × 0.05 × 2 = 7
I = $ 7.00
The simple interest accumulated
on a principal of $ 70.00
at a rate of 5% per year
for 2 years is $ 7.00.
what is the missing angle
Answer:
x=59deg
Step-by-step explanation:
We will use tangent to find the angle because we do not know the length of the hypotenuse.
Tan(x)=opp/adj
Tan(x)=30/18
Tan(x)~59
So the last option is correct. 59deg

3) -2x – 3y = -7
-4x + y = 21
A) (-8, 4)
C) (2, 4)
B) (-4,5)
D) No solution
Answer: B) (-4,5)
Step-by-step explanation:
Begin the problem by solving for y with the second equation. Add -4x to both sides of the equation so it reads y=4x+21. Then, substitute y into the first equation and solve. -2x-3(4x+21)=-7 turns into -14x-63=-7, which becomes -14x=56. Divide 56/-14 to get -4 for x. Since only one answer has -4 as an option for x, that's the correct answer.

SPEED, DISTANCE AND TIME
please please !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! emergency will give thanks
1) A cyclist travels a distance of 90 miles in 5 hours. What
was her average speed?
2) How far along a motorway would you travel if you drove at
70 mph for 4 hours?
3) I drive to Bude in Cornwall from Sheffield in about 6
hours. The distance from Sheffield to Bude is 315 miles.
What is my average speed?
4) The distance from Leeds to London is 210 miles. The train
travels at an average speed of 90 mph. If I catch the 9.30 am
train in London, at what time should I expect to arrive in
Leeds?
5) How long will an athlete take to run 2000 m at an average
speed of 4 metres per second?
6) The distance between Sheffield and Land’s End is 420
miles.
a) What is the average speed of a journey from Sheffield to
Land’s End that takes 8 hours 45 minutes?
b) If Sam covered the distance at an average speed of 63
mph, how long would it take him?
Answer:
1. Speed = 18 miles per hour
2. The distance is 280 miles.
3. The average speed is 52.5 miles per hour.
4. The time to arrive in Leeds would be 11.50 am.
5. Time = 500 s (8 minutes 20 seconds)
6. speed = 48 miles per hour
b. time taken = 6 hours 40 minutes
Step-by-step explanation:
1. Distance = 90 miles and time = 5 hours
speed = [tex]\frac{distance}{time}[/tex]
= [tex]\frac{90}{5}[/tex]
= 18
average speed of the cyclist is 18 miles per hour.
2. speed = 70 mph, and time = 4 hours
speed = [tex]\frac{distance}{time}[/tex]
distance = speed x time
= 70 x 4
= 280 miles
The distance is 280 miles.
3. distance = 315 miles, and time = 6 hours.
speed = [tex]\frac{distance}{time}[/tex]
= [tex]\frac{315}{6}[/tex]
= 52.5
The average speed is 52.5 miles per hour.
4. distance = 210 miles, and speed - 90 mph.
speed = [tex]\frac{distance}{time}[/tex]
time = [tex]\frac{distance}{speed}[/tex]
= [tex]\frac{210}{90}[/tex]
= 2 hours 20 minutes
The time to arrive in Leeds would be 11.50 am.
5. distance = 2000 m, and speed = 4 m/s.
time = [tex]\frac{distance}{speed}[/tex]
= [tex]\frac{2000}{4}[/tex]
= 500 s
It would take the athlete 500 s (8 minutes 20 seconds) to cover the distance in the given speed.
6. distance = 420 miles, and time = 8 hours 45 minutes
But, 8 hours 45 minutes = 8[tex]\frac{3}{4}[/tex] hours.
speed = [tex]\frac{distance}{time}[/tex]
= [tex]\frac{420}{8\frac{3}{4} }[/tex]
= 420 ÷ [tex]\frac{35}{4}[/tex]
= 420 x [tex]\frac{4}{35}[/tex]
speed = 48 miles per hour
(b) distance = 420 miles, speed = 63 mph.
time = [tex]\frac{distance}{speed}[/tex]
= [tex]\frac{420}{63}[/tex]
= 6 hours 40 minutes
time taken = 6 hours 40 minutes

Evaluate 4 ^ x for (a) x = - 2 and (b) x = 3 . Write your answers in simplest form
The value of 4ˣ for x = -2 and x = 3 is 0.0625 and 64 respectively.
What is an exponential function?The formula for an exponential function is f (x) = aˣ, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.
Given function 4ˣ
when x = -2
4ˣ = 4⁻²
using a⁻ⁿ = 1/aⁿ
4⁻² = 1/4² = 1/16
4⁻² = 0.0625
and x = 3
4ˣ = 4³
4³ = 4 x 4 x 4 = 64
Hence the values are 0.0625 and 64 for x = -2 and 3.
