A flea weighs 8 decigrams, and an ant weighs 3 milligrams. How much more does a flea weigh than an ant?

dusya [7]

In this question weight of a flea and an ant is given, but their units are different. So comparing and finding out the weight of flea and ant would be difficult. First thing that needs to be done is to bring the units of both the flea and the ant under same unit.
Weight of flea = 8 decigrams
Weight of ant = 3 milligrams.
Now let us convert the weight of the flea from decigrams to milligrams.
We already know that
1 decigram = 100 milligram
Then
8 decigrams = 100 * 8 milligrams
= 800 milligrams
Then
The weight by which the flea is greater than the ant = (800 - 3) milligrams
= 797 milligrams.
So the flea weighs 797 milligrams more than the ant.

Can someone help me with number nineteen

garik1379 [7]

Answer: $\frac{15}{52}$ , Less

<u>Step-by-step-explanation:</u>

This year: $\frac{Day 4}{Day 1 + Day 2 + Day 3 + Day 4} = \frac{15}{13+12+12+15} = \frac{15}{52}$

Last year: $\frac{Day 4}{Day 1 + Day 2 + Day 3 + Day 4} = \frac{15}{10+8+10+12} = \frac{12}{40}$ = $\frac{3}{10}$

Compare this year's with last years by converting the fractions to decimals:

This year: $\frac{15}{52}$ = 0.288

Last year: $\frac{3}{10}$ = 0.300

This year (0.288) is less than last year (0.300)

Which lines have slope -4/5 and contains point (0,1)?

miv72 [106K]

ANSWER

The required line is BC

EXPLANATION

We want to find the line that passes through
$(0,1)$

and has slope
$m = - \frac{4}{5}$

Since the x-value of the given point is zero, the point

$(0,1)$

is the y-intercept.

From the above graph, the two lines that contains
$(0,1)$

are line CE and line BC.

Since, the slope

$m = - \frac{4}{5}$
is negative, line BC is the required line because it is sloping backwards.

We can confirm this by using the point,

$B(-5,5)$

and

$C(0,1)$

to find the slope and obtain

$m = \frac{5 - 1}{ - 5 - 0} = - \frac{4}{5}$
