Answer:
BD = 12 :)
Step-by-step explanation:
Alright, we'll need the Pythagorean theorem for this!
So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)
DC = 5
We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:
BD^2 + DC^2 = BC^2
BD^2 + 5^2 = 13^2
BD^2 + 25 = 169
BD^2 = 169 - 25 = 144
BD = √144 = 12 :)
Explanation:
1. It means that Nikoleta is longer and heavier than 10% of children her age.
2. We generally expect that a change from being in the 50th percentile to the 10th percentile signifies a condition that is interfering with normal growth. That is not usually considered desirable.
Answer:
rate of motorboat: b
rate of current: c
So the rate the boat travels upstream is $b - c$, and the rate it travels downstream is $b + c$
Step-by-step explanation:
d = rt
200 = (b - c)\cdot 5
200 = (b + c)\cdot 4
b - c = 40
b + c = 50
Adding these equations, we get:
2b = 90
b = 45
So
c = 50 - 45 = 5
<u>Therefore the rate of the boat is 45kph, and the rate of the current is 5kph</u>
Hope this helps :)
The estimate of the given subtraction operation is 27,000
<h3>Estimating the value of numbers </h3>
From the question, we are to estimate the value of given operation. The operation is a subtraction operation.
The given subtraction operation is,
46,214 - 18,941
First, we are to round each number to the nearest thousand.
Round 46,214 to the nearest thousand
46,214 ≈ 46,000
Also,
Round 18,941 to the nearest thousand
18,941 ≈ 19,000
Now, subtract
46,000 - 19,000 = 27,000
Hence, the estimate of the given subtraction operation is 27,000

Answer:
Step-by-step explanation:
y = mx + b
slope(m) = 6
(-5,-8)...x = -5 and y = -8
now we sub and find b, the y int
-8 = 6(-5) + b
-8 = - 30 + b
-8 + 30 = b
22 = b
so ur equation is : y = 6x + 22 <===
