Is anyone good at word problems?

Georgia [21]

Answer:

X + P = 34

330X + 250P = 9620

Step-by-step explanation:

The question tells us that there were 34 consoles sold. Therefore, we can draw the straight forward conclusion that whatever combination of consoles were sold, the number Xboxes (X) and PS4s (P) sold together has to be 34 in total. Thus:

X + P = 34

Now, we know the each Xbox sold for $330, and each PS4 sold for $250, and the total sales from the consoles bought was $9620. Thus:

$330X + $250P = $9620

Hope this helps!

A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx

tester [92]

Answer:

b=-18

Step-by-step explanation:

If a line that passes through the point $P(x_o,y_o)$ and it has slope $m$ , the equation of the line is:

$y-y_o=m(x-x_o)~=>y=mx+y_o-mx_o~=>b=y_o-mx_o\\\\b=-6-4(3)=-18$

Geometry Surface area and volume

Zigmanuir [339]

Answer:

$volume=558.9$

Step-by-step explanation:

find the volume of the cone and the hemisphere and add them together

cone:

$Vcone=\pi r^{2} \frac{h}{3} \\\\V=\pi (5.3)^2(\frac{8.4}{3} )\\V=\pi (28.09)(2.8)\\V=247.09\pi \\V=247.1$

hemisphere:

$Vhemisphere=\frac{2\pi r^3}{3} \\V=\frac{2\pi (5.3)^3}{3} \\V=\frac{2\pi (148.877)}{3} \\V=\frac{297.754\pi }{3} \\V=\frac{935.421}{3}\\ V=311.8$

add the volumes together:

$Vol=247.1+311.8\\Vol=558.9$
