Answer:

503 is the answer

Step-by-step explanation:

If you use Pemdos you have to start by doing the exponent then you multiply then after that you will have to do addition and that is how you get your answer

Answer:

503

Step-by-step explanation:

Ok, to tackle this problem we are going to take it section by section. First what we are going to do is apply PEMDAS (Parentheses, Exponent, Multiplication, Divison, Addition Subtarction) to this probelm and solev in taht order.

We see that the 10 has an exponnet of 2, so really this is just saying 10 to the power of 2, or 100.

Then we would solve the rest of the equation.

5(100)+3

And we get an answer of 503

An equilateral triangle with a side length of 6mm and a height of 5.2mm is divided vertically into halves. Find the area of one

Viefleur [7K]

There are two ways you could go about solving this.

You could divide the length of the base (6mm) by 2 and use that to find the area or you could find the area of the whole triangle using 6mm and divide that by 2.

I will use the first method I described:

base = 6/2

base = 3 mm

height = 5.2 mm

area = bh/2

area = (3 * 5.2)/2

area = 7.8 square mm

(don't forget your units)

Using the other method would look like this:

area = bh/2

b = 6

h = 5.2

area = (6 * 5.2)/2

area = 15.6 square mm

area/2 = 7.8 square mm

As you can see either method yields the same result.

Hope this helped.

Cheers and good luck,

Brian

The midpoint of segment QR is M(-2, 9). One end point of segment QR is Q(-8, 12). Find the coordinates of the other endpoint, R.

DanielleElmas [232]

Here,

The midpoint of segment QR is M

m(-2,9) x3=-2,y3=9

Q=(-8,12)x1=-8,y1=12

R=x2,y2

we know that,

$\tt{ m=\dfrac{Q+R}{2} }$ ⠀

So,

x3= $\tt{\dfrac{x1+x2}{2} }$ ⠀

$\tt{-2=\dfrac{-8+x2}{2} }$ ⠀

$\tt{-2×2=-8+x2 }$ ⠀

$\tt{x2=8-4 }$ ⠀

$\tt{x2=4 }$ ⠀

x2=4

now we find the y coordinate y2.

y3= $\tt{\dfrac{y1+y2}{2} }$ ⠀

$\tt{9=\dfrac{12+y2}{2} }$ ⠀

$\tt{9×2=12+y2 }$ ⠀

$\tt{y2=18-12 }$ ⠀

$\tt{y2=6 }$ ⠀

y2=6

Now we get the two coordinate of R

so,

R=(x2,y2)=(4,6)

A store is having a sale on jelly beans and trail mix. For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is

klasskru [66]

3j+2t=14 subtract 2t from both sides

3j=14-2t divide both sides by 3

j=(14-2t)/3

...

5j+6t=28, using j found above in this equation yields.

5(14-2t)/3+6t=28 perform indicated multiplication on left side

(70-10t+18t)/3=28 multiply both sides by 3

70-10t+18t=84 combine like terms on the left side

70+8t=84 subtract 70 from both sides

8t=14 divide both sides by 8

t=$1.75, and since j=(14-2t)/3

j=(14-2(1.75))/3

j=$3.50

So a pound of trail mix costs $1.75 and a pound of jelly beans costs $3.50.
