Michael is planting a garden in the shape of a right triangle. He wants 4 tickseed plants for each square meter of area. How man

Paladinen [302]

Answer:

336 plants

Step-by-step explanation:

To find the number of tickseed plants that Michael needs to plant in his garden, we have to find the area of the garden first.

We notice that the garden has the shape of a right triangle: so, we have to find the area of the right triangle.

The area of a triangle is given by the formula

$A=\frac{1}{2}bh$

where

A is the area

b is the length of the base

h is the height of the triangle

From the figure, we see that:

b = 7 m is the length of the base

h = 24 m is the height of the triangle

Therefore, applying the formula, we find the area of the garden:

$A=\frac{1}{2}7\cdot 24 =84 m^2$

We also know that Michael wants to plant 4 tickseed plants for each square meter of area; therefore, the total number of plants that Michael will plant is 4 times the area of the garden, so:

$N=4A=4\cdot 84=336$

Well I can use math in my daily life is when I want to build a house bird for example or even cook and follow a recipe that has math in it , example is the measuring cups , how much needs to go in and all that. Even when building a house you need to use math, or working at a cash register , to be able to count the money you need to give back to the person or take. Another example is music aswell because you need to follow the numbers when playing an instrument, not much music but yeah. And a few more examples ; Managing money $$$

Tems11 [23]

Answer: B. (2,1)

Step-by-step explanation:

its not c because if you look at R you see that it is going 4,3 not 3,4 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then the x-axis.

It's not D because if you look at Q you see that it is going 3,5 not 5,3 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then x-axis.

That's the same thing for A so your answer is b.
