harina [27]3 years ago
4 0

Answer:

cscA = \frac{5}{4}

Step-by-step explanation:

Using the identity

csc x = \frac{1}{sinx} , then

sinA = \frac{opposite}{hypotenuse} = \frac{BC}{AB} = \frac{8}{10} = \frac{4}{5} , thus

cscA = \frac{1}{\frac{4}{5} } = \frac{5}{4}

Peter drives his van a distance of 54 km. He leaves the depot at 10:55 and arrives back at 12:38. Calculate his average speed
OLga [1]

Answer:

31.46 km/hr to the nearest 100th

Step-by-step explanation:

10:55 to 11:00 is 5 min

11:00 to 12:00 is 60 min

12:00 to 12:38 is 38 min

That's 5 + 60 + 38 = 103 min = 103/60 hr. = t

d = rt

54 = 103/60(r)

r = 54(60)/103 =31.46 km/hr to the nearest 100th

Solve the system of equations by using substitution.<br> x+8y=-2<br> x-3y=20
zysi [14]

Answer:

(14, -2)

Step-by-step explanation:

To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:

x+8y=-2\\x=-2-8y

Now we know what <em>x</em> equals. Let's substitute this into the second equation:

x-3y=20\\(-2-8y)-3y=20

We can then simplify:

-2-8y-3y=20 Given equation

-2-11y=20 Combine y terms

-11y=22 Add 2

y=-2 Divide by -11

So, we now know the value of y = -2.

To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:

x+8y=-2

x+8(-2)=-2 Substitute for y

x-16=-2 Distribute 8

x=14 Add 16

So, we now know the value of x = 14.

Therefore, we know a solution to the system of equations is (14, -2).
