An aerogel meringue weighs 1.17 grams. It is 96% air and 1.3 egg whites. The rest is sugar. How much sugar is in the meringue, r
miv72 [106K]

Answer:

0.03 grams

Step-by-step explanation:

Given:

An aerogel meringue weighs 1.17 grams

It is 96% air and 1.3 egg whites.

The rest is sugar.

To find:

How much sugar is in the meringue, rounded to the nearest hundredth?

Solution:

An aerogel meringue weighs = 1.17 grams

Percentage of air = 96%

Percentage of egg whites = 1.3%

Now, to find first of all to find the percentage of sugar, we will add the percentage of air with the percentage of egg whites,

96% + 1.3% = 97.3%

As here given that the remaining percentage is sugar therefore,

100% - 97.3% = 2.7%

Now, to find the quantity of sugar in meringue,

2.7\% \ of 1.17 gram =\frac{2.7}{100} \times1.17 = \frac{3.159}{100} =0.0315 \ grams

Therefore, sugar is 0.03 grams in the meringue.

Find the coordinates of the intersection of the diagonals of parallelogram HJKL with the given vertices: H(-1, 4), J(3, 3), K(3,
lakkis [162]

Answer:

(1, 1)

Step-by-step explanation:

Given vertices of the <u>parallelogram</u>:

  • H = (-1, 4)
  • J = (3, 3)
  • K = (3, -2)
  • L = (-1, -1)

Therefore the <u>parallel sides</u> are:

\sf \overline{HJ} \parallel \overline{LK}\:\: \textsf{ and }\:\: \overline{LK} \parallel \overline{HL}

Therefore, the <u>diagonals</u> of the parallelogram are:

\sf \overline{LJ} \:\: \textsf{ and }\:\:\overline{HK}

To find the <u>coordinates of the intersection of the diagonals</u>, either:

  1. draw a diagram (see attached) and determine the point of intersection of the diagonals from the diagram, or
  2. determine the midpoint of either diagonal (as the diagonals of a parallelogram bisect each other, i.e. divide into 2 equal parts).

<u>Midpoint between two points</u>

\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)

To find the <u>midpoint of diagonal LJ</u>, define the endpoints:

  • (x_1,y_1)=L=(-1, -1)
  • (x_2,y_2)=J=(3,3)

Substitute the defined endpoints into the formula and solve:

\begin{aligned} \implies \textsf{Midpoint of LJ} & =\left(\dfrac{3-1}{2},\dfrac{3-1}{2}\right)\\ & =\left(\dfrac{2}{2},\dfrac{2}{2}\right)\\ & =\left(1,1\right) \end{aligned}

Therefore, the coordinates off the intersection of the diagonals of parallelogram HJKL are (1, 1).

“Ms. Blanco drove her car at a speed of 80 kilometers per hour for 1 1/2 hours, then at a speed of 100 kilometers per hour for 2
lara31 [8.8K]
I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250

250+120=370!!

answer : 370 kilometers per hour
