height,h = 3"

base, b = length, l = 2

area of triangle, t = bxh/2...eqn 1

area of square, s = l^2...eqn 2

area of pyramid, p =4t + s...eqn 3

subst h = 3 and b = 2 in eqn 1

t = 3x2/2 = 3

subst l =2 in eqn 2

s = 2^2 = 4

subst t = 3 & s = 4 in eqn 3

p = 4(3) + 4 = 16sq inch

If you are looking for an expression it would be x < 4 and the < has a line underneath for less than or equal to. If this is right could I possibly have brainliest? Hope this helped!! :)

Step-by-step explanation:

having denominator 6,

X/6= 2/3

X= 4

so, 4/6= 2/3

having numerator 10,

10/X= 2/3

X= 15

so, 10/15= 2/3

6) Jesse is buying a home for $450,000 at 7.8% interest and Jesse is putting 30% down? He wishes to buy 3 points what is the cos

krek1111 [17]

Answer:

$9450

Step-by-step explanation:

Given that:

The price of the home = $450000

The interest = 7.8%

Down payment = 30% of price of the home

i.e 0.3 × 450000 = 135000

The principal outstanding balance = 450000 - 135000

= 315000

Finally, the cost of 3 points will be;

$= 315000 \times \dfrac{3}{100}$

= $9450

Can someone help me with this please - can you also give a step by step not just an answer

n200080 [17]

Answer:

The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.

7/9 x 5 2/5 = 7/9 x 27/5 = 189/45 = 4 9/45 = 4 1/5

1 3/4 x 4 1/6 = 7/4 x 25/6 = 175/24 = 7 7/24

Using the volume of the spherical balloon, it is found that it will take 24 hours for the balloon to become completely empty.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given by:

$V = \frac{4\pi r^3}{3}$

Aspherical balloon has a radius of 6 feet, hence the volume is:

$V = \frac{4\pi 6^3}{3} = 905$

It has already lost 20% of it's air, and air is leaking out of the balloon at a rate of 30 cubic feet per minute, hence the volume after t minutes is given by:

$V(t) = 0.8(905) - 30t$
