Turning 2.45 into a percent

2 answers:

8 0

As a percent is out of 100% or 1 (as a whole number), the best thing to do is multiply it by ten, until you get a whole number. As you cannot have a decimal in a percentage. 2.45x10= 24.5. This is still a decimal, so you need to multiply it be ten again, 24.5x10= 245. Therefore, 2.45 is a percent is 245%

If you want to convert a number to a percentage, multiply the number by 100 with a sign %.

2.45 × 100% = 245%

An experiment consists of rolling a die, flipping a coin, and spinning a spinner divided into 7 equal regions. The number of ele

oee [108]

Answer:

Option A.

The number of elements in the sample space of this experiment is 84

Step-by-step explanation:

The sample space for an experiment represents the number of possible results that may occur when conducting the experiment.

When throwing a die and observe the number obtained there are 6 possible results

When throwing a coin there are 2 possible results.

When spinning a wheel divided into 7 regions we have 7 possible outcomes.

If we combine these three experiments, then the sample space S is composed of the product of the possible results of each experiment.

$S = (6)(2)(7)\\\\S =84$

The angels in a triangle should be 180° all
85+64+30=179<180
so we should add 1° to the first one
the angels would be 86 64 30

ella [17]

Answer:

$P(x)=-2x^2+28x-66$

Step-by-step explanation:

$P(x)=-2(x-3)(x-11)\\\\P(x)=-2(x^2-3x-11x+33)\ \ \ \ \ \ multiplication\ of\ (x-3)\ and\ (x-11)\\\\P(x)=-2(x^2-14x+33)\ \ \ \ \ \ \ distributive\ property\\\\P(x)=-2x^2+28x-66$

Answer:

{A, E, H, J}, {B, C}, {D, F, G}

Step-by-step explanation:

The length:width ratios of the various rectangles are ...

A — 9 : 6 = 3 : 2
B — 3 : 1
C — 6 : 2 = 3 : 1
D — 3 : 3 = 1 : 1
E — 6 : 4 = 3 : 2
F — 1 : 1
G — 6 : 6 = 1 : 1
H — 3 : 2
J — 6 : 4 = 3 : 2

The rectangles with 1 : 1 side ratios are D, F, G.

The rectangles with 3 : 1 side ratios are B, C.

The rectangles with 3 : 2 side ratios are A, E, H, J.

The rectangles in each of the following sets are proportional to one another:

{A, E, H, J}, {B, C}, {D, F, G}

YMMV if you consider 3:2 different from 2:3.
