The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.

A=1/2(9)(4)

Multiply to get 18 square cm, which is choice D.

Easiest question I have ever seen! :)
We know the formula of the area of a triangle
= $\frac{1}{2}$ ×base×height
The height given is 4 cm (we should take the perpendicular height)
And the base length is 8 cm
Simply, we just substitute the given numbers
= $\frac{1}{2}$ ×8×4
=18 cm²
The answer is D: 18 square m

Deion divided 1/2 of a liter of plant fertilizer evenly among some smaller bottles. He put 1/8 of a liter into each bottle. How

Klio2033 [76]

Answer:

4 bottles

Step-by-step explanation:

Given

$Fertilizer = \frac{1}{2}L$

$Bottles = \frac{1}{8}L$

Required

Determine the number of bottles

Represent the number of bottles with N

<em>This implies that N bottles of </em> $\frac{1}{8}L$ <em> fit into </em> $\frac{1}{2}L$ <em> of fertilizer. The relationship between them is:</em>

<em></em> $Fertilizer = Bottles * N$

$\frac{1}{2}L = \frac{1}{8}L* N$

$\frac{1}{2} = \frac{1}{8}* N$

Multiply through by 8

$8 * \frac{1}{2} = 8 * \frac{1}{8}* N$

$4 = 1* N$

$4 = N$

$N = 4$

<em>Hence, there are N = 4</em>

Suppose Brianna invests $1,300 each year for 5 years, in an annuity that pays 6% annual interest, compounded annually. What perc

love history [14]

Answer:

74.73%

Step-by-step explanation:

First, we're gonna find out her total amount

We're gonna use the count interest formula: P = A(1 + r)ⁿ

P = final amount

A = starting amount (1300)

r = rate (0.06)

n = years (5)

P = 1300(1 + 0.06)⁵

P = 1739.693251

Now divide the starting amount by the total amount

1300 ÷ 1739.693251 = 0.7472582
