Answer:

Area of the given figure is 21 square units

Step-by-step explanation:

Area of the rectangle formula is length times width

Area of the top rectangle

Length = 5 and width = 3

So area of top rectangle =5 times 3 is 15 square units

Area of bottom rectangle

length =2 and width =3

So area of bottom rectangle is 2 times 3 is 6 square units

Total area = $15+6= 21$ square units

1 cup = 1/2 pint, so where it says 4 cups we'll just read 2 pints.

1. In one show we serve 30 × 2 pints of small and 42 × 6 pints of regular.

Total = 30 × 2 + 42 × 6 = 60 + 252 = 312 pints

Answer: 312 pints

2. 8 pints per gallon, 2 gallons per container makes 16 pints per container.

312 pints / 16 pints per container = 19.5 containers

We round up since we need a whole number of containers.

Answer: 20 containers

We can't really see question 3.

Perform the following operations and write the answers in radical form. Part A:√7+√3+√98−√18 Part B:3√5−3√11+2√121−3√90

Sveta_85 [38]

Answer:

$\sqrt{7}+\sqrt{3}+4\sqrt{2}$
$3\sqrt{5}-3\sqrt{11}+22-9\sqrt{10}$

Step-by-step explanation:

Part A ;

$\sqrt{7} +\sqrt{3} +\sqrt{98} -\sqrt{18} \\\\\sqrt{98}=7\sqrt{2}\\\sqrt{18}=3\sqrt{2}\\\\=\sqrt{7}+\sqrt{3}+7\sqrt{2}-3\sqrt{2}\\\\\mathrm{Add\:similar\:elements:}\:7\sqrt{2}-3\sqrt{2}=4\sqrt{2}\\\\=\sqrt{7}+\sqrt{3}+4\sqrt{2}$

Part B ;

$3\sqrt{5} - 3\sqrt{11} + 2\sqrt{121} -3\sqrt{90} \\\\2\sqrt{121}=22\\3\sqrt{90}=9\sqrt{10}\\\\=3\sqrt{5}-3\sqrt{11}+22-9\sqrt{10}$

Which of the four graphs has the greatest standard deviation? please help me

Norma-Jean [14]

Answer:

Standard deviation is how far away the values are from the mean.
All of your graphs have normal distribution, meaning the mean is in the center.

<em>The more spread out your graph is, the greater the standard deviation.</em>

So the option with the most spread out graph, which I think is A, can't see very clear.
