D=rt Divide (r) on both sides so that your t is by its self
therefore it looks like so

d/r= t

Kyra is using rectangular tiles of two types for a floor design. They Tyler each type is shown below:

sattari [20]

Answer: b) the tiles are not similar because both SP:SR is 5:4 and MJ:ML is 5:2

<u>Step-by-step explanation:</u>

We are given that the tiles are rectangular which implies that they both have a 90° angle.

In order to prove similarity, We need to show that the lengths and widths are proportional.

P Q R S

J K L M

a) PQ : QR JK : LM

w=4 L=5 w=2 w=2

↓

We need Length (not width)

b) SP : SR MJ : ML

L=5 w=4 L=5 w=2

5 : 4 5 : 2

When comparing length to width they do not have the same ratio so the rectangles are not similar.

c) PQ : QR JK : KL

w=4 L=5 w=2 L=5

4 : 5 2 : 5

When comparing width to length they do not have the same ratio so the rectangles are not similar.

d) SR : ML PQ : JK

w=4 w=2 w=4 w=2

↓ ↓

We need Length (not width)

Mr. Fulton bought 12 1/2 pounds of ground beef for the cookout. He plans on using 1/4 pound of ground beef for each hamburger. H

vekshin1

Answer:

Mr. Fulton can make 50 hamburgers.

Step-by-step explanation:

Given:

Total amount of ground beef = $12\frac{1}{2} \ pounds$

$12\frac{1}{2}$ can be Rewritten as $\frac{25}{2}$

Total amount of ground beef = $\frac{25}{2}\ pounds$

Amount of beef used for each hamburger = $\frac{1}{4}\ pound$

We need to find the number of hamburgers could he make.

Solution:

Now we can say that;

number of hamburgers can be calculated by Total amount of ground beef divided by Amount of beef used for each hamburger.

framing in equation form we get;

number of hamburgers = $\frac{\frac{25}{2}}{\frac{1}{4}} = \frac{25}{2}\times \frac{4}{1} = 50$

Hence Mr. Fulton can make 50 hamburgers.

IM really struggling on these math problems can anyone help and help me how to show the WORK! PLEASE

Helen [10]

Answer:

For the first one it is 5x+2

Step-by-step explanation:

(9x+5) - (4x+3) = ?

First you minus the x's together so,

9x-4x which would equal 5x

then you minus the 5 and 3 together so,

5-3 which would equal 2

then you put the 5x and the 2 together and you get

5x+2 :-)

For the rest of the problems, use this as an example!

Use the divergence theorem to find the outward flux of the vector field F(x,y,z)=2x2i+5y2j+3z2k across the boundary of the recta

aksik [14]

Answer:

The answer is "120".

Step-by-step explanation:

Given values:

$F(x,y,z)=2x^2i+5y^2j+3z^2k \\$

differentiate the above value:

$div F =2 \frac{x^2i}{\partial x}+5 \frac{y^2j}{\partial y}+3 \frac{z^2k }{\partial z} \\$

$= 4x+10y+6z$

$\ flu \ of \ x = \int \int div F dx$

$= \int\limits^1_0 \int\limits^3_0 \int\limits^1_0 {(4x+10y+6z)} \, dx \, dy \, dz \\\\ = \int\limits^1_0 \int\limits^3_0 {(4xz+10yz+6z^2)}^{1}_{0} \, dx \, dy \\\\ = \int\limits^1_0 \int\limits^3_0 {(4x+10y+6)} \, dx \, dy \\\\ = \int\limits^1_0 {(4xy+10y^2+6y)}^3_{0} \, dx \\\\ = \int\limits^1_0 {(12x+90+18)}\, dx \\\\= {(12x^2+90x+18x)}^{1}_{0} \\\\= {(12+90+18)} \\\\=30+90\\\\= 120$
