Answer:
93.5 mm
Step-by-step explanation:
1. Add all the rainfall readings together to find the total rainfall.
12.48+8.82+27.51+44.73=93.54
2. One decimal place means you'll be rounding 93.54 to the nearest tenth. Round down if the decimal place immediately to the right is less than 5, round up if it is greater than or equal to 5. Since 4 is the value in the hundredths place and 4<5, we are going to round down.
3. The answer is 93.5 mm, don't forget your units.
Hope you found this helpful, have a nice day.
Answer:
multiply all those numbers together
Step-by-step explanation:
Triangles ABC and ADE are similar triangles. That means the sides are all scaled by the same factor.
To go from side BC to side DE, you multiply by 1.25. That means 1.25 is your scale factor. Now apply that factor to the bottom side to get your answer.
Side AB is 6. That means side AD is 6 x 1.25 = 7.5. That means x = 7.5 - 6 = 1.5
Answer:
it's used in conjunction with variance
Answer:
x = - 5, x = - 2
Step-by-step explanation:
Given
f(x) = x² + 7x + 10
To find the x- intercepts let f(x) = 0, that is
x² + 7x + 10 = 0 ← in standard form
(x + 2)(x + 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 5 = 0 ⇒ x = - 5
The x- intercepts are (- 5, 0) and (- 2, 0 )
