Answer:

10 Square feet or square meter

Step-by-step explanation:

Area of a triangle = bh / 2

b represents the base which is 4

h represents the height which is 5

bh / 2 = 4 × 5 / 2

Area = 20 / 2

Area = 10

:. The Area of the triangle is 10 square feet or square meter

Which of the following equations best models the data plotted below?

ICE Princess25 [194]

The key with these problems is to find which function has the closest y-intercept to the graph, and then try to figure out which one best approximates the slope.
Here are our options:
<span>A. y = x + 4
B. y = 4x + 9
C. y = x + 18
D. y = 3x + 22

Which has the closest approximation of the y-intercept?
The y-intercept is not directly given, but we can assume it is less than 10.
That leaves us with A and B.

Which has the closest approximation of the slope?
The graph, on average, seems to move up about 60 and over about 15.
Slope = rise/run = 60/15 = 4. Although the slope isn't exactly 4, it's much closer to 4 than 1, which is slope for option A.

Therefore, the answer is
B) y= 4x + 9

If 18 percent of the beads in a bag are green, 25 percent are red and 40 percent are purple. What is the probablity of choosing

sweet [91]

Answer:

$P(G\ then\ R)=0.045$

Step-by-step explanation:

From the question we are told that:

Percentage of Green beads $P_g=18$

Percentage of Red beads $P_r=18$

Percentage of Purple beads $P_p=18$

Therefore

Probability of choosing a Green bead is

$P(G)=0.18$

Probability of choosing a Red bead is

$P(R)=0.25$

Generally the equation for choosing a green bead then a red bead is mathematically given by

Since Outcomes are independent

$P(G\ then\ R)=0.18*0.25$

$P(G\ then\ R)=0.045$

Rosa has $117 in her savings account and $95 in her checking account. Each week she will put $21 into her savings account and $2

mr_godi [17]

Answer:

It will take Rosa 5 and a half (5.5) weeks to have the same amount of money in both accounts.

Step-by-step explanation:

For this problem, we will have to set two expressions equal to each other. The first expression will represent Rosa's saving account, which already has $117 in it. Every week ( $x$ ), she adds $21 to her savings account:

$21x+117$

The second expression will represent Rosa's checking account. Rosa's checking account already has $95 in it. Every week ( $x$ ), she adds $25 to her checking account:

$25x+95$

Now that we have our two expressions, set them equal to each other. This is our equation that will be used to find the number of weeks ( $x$ ) it takes until Rosha has the same amount of money in both accounts:

$21x+117=25x+95$
