What are the solutions to<br> (m +11)2 = 64?

mel-nik [20]

Answer:

(21 + 11)2 = 64

So, I don't think teachers do this, but this is my way of doing it

Okay, so first, I divided 64 by 2 :

64 ÷ 2 = 32

Then, I subtracted 11 from 32:

Now, to check, just do the problem :

(21 + 11)2 = 64

32 * 2 = 64

$89.75 scooter; 7 1/4% tax

Kazeer [188]

If you are looking for the sales tax then you take 89.75 times .075 this will give you 6.73 now you just add 6.73 to 89.75 and you get..

sales tax = $96.48

but if you are looking for the %off you are going to do 89.75 minus 6.73 and you will get....

%off= $83.02

Nicki has 30 pencils. for every green pencil, she has 5 purple pencils. how many pencils of of each color could she have

Hatshy [7]

Answer:

Step-by-step explanation:

(1) P = 5G

(2) G + P = 30

Substituting (1) into (2) gives:

G + 5G = 30

6G = 30

G =5

So there are 5 green pencils.

Now using that in (1) gives us P = 5 x 5 = 25

So there are 5 green pencils and 25 purple pencils.

Move triangle ABC so it lies on top of triangle DEF, triangle GHI, and triangle JKL. How many units do you have to move triangle

dusya [7]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, as the diagram of coordinates of the three triangles are not given.

A general explanation is as follows:

First, record the coordinates of the corresponding points of the three triangles.

For instance; In triangles ABC, DEF and GHI; A, D and G are corresponding points.

Now, assume the coordinates are:

$A = (1,1)$

$D = (1,5)$

$G= (-2,1)$

Point D is 4 points to the right of A;

i.e.

$D =(1,1+4) = (1,5)$

Hence, ABC will be moved 4 units right to lie on DEF

Similarly, point G is 3 units down of A

i.e.

$G =(1-3,1) = (-2,1)$

Hence, ABC will be moved 3 units down to lie on GHI.

There is 1/4 ounce of yeast in every 2 1/4 teaspoon of yeast. A recipe calls for 2 teaspoons of yeast. How many ounces of yeast

MrRissso [65]

1/4 ounce of yeast ... 2 1/4 teaspoons of yeast
x ounce of yeast = ? ... 2 teaspoons of yeast

If you would like to know how many ounces of yeast need to be in the recipe, you can calculate this using the following steps:

1/4 * 2 = x * 2 1/4
1/2 = x * 9/4 /*4/9
x = 1/2 * 4/9
x = 2/9

Result: 2/9 ounce of yeast needs to be in this recipe.
