We first must find the value of angle z.
Angle z = 90° - 42°
Angle z = 48°
We now use the sine function to find y.
sin(48°) = 35/y
y = 35/sin(48°)
y = 47.0971455362
We now round off to two decimal places.
y = 47.10
I hope this helps....
For this case, the first thing you should do is define a variable.
We have then:
g: unknown number.
We now write the expression in algebraic form.
the sum of 5 and a number:
g + 5
Answer:
An expression that means the sum of 5 and a number is:
C. g + 5
Answer:
Altogether, they had ?28
Step-by-step explanation:
Had Obi spent only ?12, they would have been even. Thus ?12 is the same as 5-2 = 3 "ratio units". So, each "ratio unit" is worth ?12/3 = ?4.
Then Obi started the day with 5·4 = 20, and Obi started the day with 2·4 = 8. Obi ended with 0, which is 8 less than Rudy.
Altogether, they started with 20 + 8 = 28 of whatever a ? is.
D (the last option)
x 2 -2 4 -4
y 8 8 12 12
because the x values should not repeat for the y values.
Answer:
Linear equation of train is:
x =62.5t
Step-by-step explanation:
Given a train A.
Train A can travel 500 miles in 8 hours.
so in one hour this train a can travel 500/8 miles
i.e train A travel distance in one hour = 500/8 = 62.5 miles
That meas speed of train= 62.5 miles/hour
Since the travelling rate of train is constant.
So we can write a linear equation that represents the situation.
Let the distance covered by train in t hours be x miles.
or Distance covered by train = Speed of train * time
or x = 62.5 * t , where t is the time in hours.
or x =62.5t
