Answer:

Step-by-step explanation:

Squaring a number (a+b) for example is a^2+2ab+b^2. So you square root x^2 and 49, you get x and seven respectively. you multiply them together and on top of that multiply the product by 2. so 7x*2 is 14x and ye

Mr frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 98 my of fertilizer 4 times

bixtya [17]

Answer:

-2755 plants

-40mg is left.

Step-by-step explanation:

Given the fertilizer amount is 1.08kg, and the amount per plant per year is (4*98mg):

#convert the weight of the fertilizer into grams then divide by quantity per plant to determine number of plants;

$Number \ of \ plants=\frac{Fertilizer \ Amount}{Quantity \ per \ plant}\\\\=\frac{1.08\times 1000000}{98\ mg\times 4}\\\\=2755.1\approx2755$

-There are 2755 plants planted.

-We subtract the fertilizer used from the total to find what is left:

$Left=Total -Used\\\\=1080000\ mg-(2755\times98\times4)\\\\=40\ mg$

Hence, 40 mg of the fertilizer is left over.

Identify the area of the trapezoid.

AveGali [126]

Answer:

112x m^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 ( b1+ b2) h

where b1 and b2 are the bases

A = 1/2 ( 11x+17x) * 8

= 1/2 ( 28x)8

= 112x m^2

If you run a marathon of 26 1/5 miles in a time of 5 4/5 how far do you run in 1 hour<br><br>pls

alisha [4.7K]

First let's make both the miles and the hours ran improper fractions:

$26+\frac{1}{5}=\frac{131}{5}\\ 5+\frac{4}{5}=\frac{29}{5}$

So, to find our miles per hour, we have to divide the miles by the hours to get: $\frac{\frac{131}{5}\text{miles}}{\frac{29}{5}\text{hours}}=\frac{131\text{miles}}{29\text{hours}} \\ \text{ Now we have to divide the top and the bottom by 29 to get our miles per hour so: }\\ \frac{\frac{131}{29}}{\text{hour}} \approx \frac{4.52 \text{miles}}{\text{hour}}$

Steps to solving y=2x+3 x=y-8

tatuchka [14]

First, plug in x=y-8 to y=2x+3
Next, it would be y=2(y-8)+3
Then, you need to distribute: y= 2y-16+3
After that, move 2y to the other side: -y= -13 (notice I also did -16+3)
Finally, divide negatives into both sides: y=13

Now to find x just plug in 13 to either of the equations: 13=2x+3
Then solve: x=5
So the FINAL answer is: (5,13)
Hope this helps!!!!!!!
