Beth travels at an average speed of 30 mph for 20 miles.
Without stopping, Beth then travels 70 miles in 1.5 hours.
Find her average speed for the entire journey to 2 dp.
Answer:
41.54 mph
Step-by-step explanation:
you need to find the total distanceand total time to find the average speed
use distance/time = speed equation
time = 1.5 hours + 40 mins = 2 hours 10 mins
distance= 20 + 70 = 90 miles
90/130 mins x 60 = 41.54 mph

200 people got an email 37 people clicked on it how do you get 18.5%
Answer:
37/200
Step-by-step explanation:
Event/Sample Space = .185 = 18.5%
Answer:
Step-by-step explanation:
If 37 people out of 200 people opened an e-mail, you can write it as 37/200.
The number above the bar is the numerator: 37
The number below the bar is the denominator: 200
Divide the numerator by the denominator to get fraction's value:
Val = 37 ÷ 200
Val = 0.185
To calculate the percent value:
0.185 = (Calculate fraction's value.)
0.185 × 100/100 =
(0.185 × 100)/100 = (Multiply that number by 100.)
18.5/100 =
18.5%; (Add the percent sign % to it.)
So that's how you get 18.5%

y - x1 = m ( x - y1 )
Y1 = 9
x1 = 5
m=slope (in this case 7)

Answer:

Step-by-step explanation:
so 8*6=48, so we know that (4*6)+(_*6) should equal 48.
4*6=24
subtract 24 by 48 and we get 24.
now you probably know that it equals 4, but to be sure, divide 24 by 6, and you'll get 4.
Answer:
From top to bottom:
1st box: 4
2nd box: 24
3rd box: 48
Step-by-step explanation:
So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.

x=
Answer:
We can fine x by using the pythagoras formula
a²+b² = c²
Which C is X
And
a= 17
b= 15
So
a² + b² = c²
(17)² + (15)² = c²
289 + 225 = c²
514 = c²
√514 = c
22.67 = c
So basically X is (22.671)
The missing side of the given right angled triangle is 8 units.
In the given right angled triangle, the hypotenuse side is 17 units, base is 15 units and the height is x units.
By using Pythagoras theorem, we get
17²=15²+x²
289=225+x²
x²=289-225
x²=64
x=√64
x=8 units.
Therefore, the missing side of the given right angled triangle is 8 units.

what number lies halfway between 16 and 38
Answer:
27
Step-by-step explanation:
The number that lies halfway between 16 and 38 is 27.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
We have to determine the number that lies halfway between 16 and 38.
This is calculated by finding the average (or mean) of the two numbers. To do this, add the numbers together (16 + 38) and divide by 2.
⇒ 54/2
The result is 27.
Thus, the number that lies halfway between 16 and 38 is 27.

Answer:
y = 30
z = 115
Step-by-step explanation:
z° + 65° = 180°
(Exterior Angles on the same side of transversal)
z° = 180° - 65°
z° = 115°
z = 115
(5y - 85)° + z° = 180°
(Linear pair angles)
(5y - 85)° + 115° = 180°
(5y - 85)° = 180° - 115°
(5y - 85)° = 65°
5y - 85 = 65
5y = 65 + 85
5y = 150
y = 150/5
y = 30
