Answer:

x = -2

Step-by-step explanation:

3x+2=−4

3x+2−2=−4−2(Subtract 2 from both sides)

3x=−6

3x /3 = −6 /3

(Divide both sides by 3)

What is an expression so that the product of a whole number and a decimal is 0.28

alisha [4.7K]

You may go the super easy way and choose 1 as the whole number and 0.28 as the decimal number. Then you'd obviously have $1\cdot 0.28=0.28$

Otherwise, to be a bit more creative, you can observe that

$0.28=\dfrac{28}{100} = \dfrac{14}{50} = \dfrac{7}{25} = 7\cdot \dfrac{1}{25}$

And since 1/25=0.04, you can also choose 7 as the integer, and 0.04 as the decimal to get

$7\cdot 0.04=0.28$

Find the volume of the solid whose base is the circle x^2+y^2=64 and the cross sections perpendicular to the x-axis are triangle

djyliett [7]

1) x² + y² = 64 is the EQUAION of a cercle with a radius R = √64 =8

2) The cross section is a triangle with H = BASE.
Since R = 8 that means the Base B= 16 and also the height H =16
This solid is then a regular cone and its Volume value is
V = πR².H
V π(8)².(16) = 2014π units³ or ≈ 3217 units³
