Answer:

= 868.1ft^3

Step-by-step explanation:

Volume of the square based pyramid = BH/3

B is the base area

H is the height of the pyramid

Base area = Length * Length

Base area = 14.1*14.1

BAse area = 198.81ft^2

Height = 13.1feet

Substitute

Volume = 198.81*13.1/3

Volume of the pyramid = 868.1ft^3

Hence the volume of a pyramid with the square base is 868.1ft^3

4/9 = 13/q<br><br> I'm supposed to solve it and round it to the nearest hundredth if necessary
Elodia [21]

Answer:

5.78

Step-by-step explanation:

Multiply 13 to both sides to get q by itself

4/9*13=q

this gives you

5.77777778=q

but we need to round it to the nearest hundredth

so

5.78

a circle has a center (3,5) and a diameter AB. The coordinates of A are (-4,6). what are the coordinates of B?
Kruka [31]
Find the length of the radius.

r= \sqrt{(3-(-4))^2+(5-6)^2}&#10;\\r =  \sqrt{7^2+(-1)^2}&#10;\\r= \sqrt{50} &#10;\\  r=5 \sqrt{2}

Find the length of the diameter.

d = 2r = 2 × 5√2 = 10√2

Point B must lie on a line AC, where C is a center of a circle.
Find equation of line AC.
A(–4, 6), C(3, 5)

y-y_1= \frac{y_2-y_1}{x_2-x_1}(x-x_1)&#10;\\y-6= \frac{5-6}{3-(-4)}  (x-(-4))&#10;\\y-6=- \frac{1}{7} (x+4)&#10;\\7y-42=-x-4&#10;\\x+7y-38=0 

The distance from B(x, y) to C(3, 5) is 5√2.
\sqrt{(x-3)^2+(y-5)^2}=5 \sqrt{2} &#10; \\(x-3)^2+(y-5)^2=(5 \sqrt{2})^2 &#10;\\(x-3)^2+(y-5)^2=50

Solve system of equations.
x+7y-38=0&#10;\\(x-3)^2+(y-5)^2=50&#10;\\&#10;\\x=38-7y&#10;\\(38-7y-3)^2+(y-5)^2=50&#10;\\(35-7y)^2+(y-5)^2=50&#10;\\1225-490y+49y^2+y^2-10y+25-50=0&#10;\\50y^2-500y+1200=0&#10;\\y^2-10y+24=0&#10;\\y^2-6y-4y+24=0&#10;\\y(y-6)-4(y-6)=0 \\(y-6)(y-4)=0 \\y_1=6,y_2=4&#10;

x_1=38-7y_1=38-7 \times 6 = 38-42=-4&#10;\\x_2=38-7y_2=38-7 \times 4 = 38-28=10&#10;

Point B could have coordinates
\\&#10;\\(x_1,y_1)=(-4,6),(x_2,y_2)=(10,4)&#10;

But (–4, 6) are the coordinates of point A.
Therefore, point B has coordinates (10,4).

Jose bought 1.5 pounds of apples for $3.60.<br><br> How much would 3/4 of a pound of apples cost?
Vladimir [108]

Answer:

$1.80 is the cost for 3/4 of a pound of apples. If you divide 1.5 over 2, it would be 3/4, which means you will divide the price too, 3.60/2 = $1.80
