Answer:

The number of cases prior to the increase in measles = 53

Step-by-step explanation:

The increase in rate of measles case = 10.2%

The total number of cases after 10.2 % increase = 58

The number of cases before 10.2 % increase in measles case = ??

Let x be the no of cases present before 10.2 % increase.

x * (100 + 10.2) % = 58

x * 110.2 % = 58

x = 58 / 110.2 = 52.63

x = 53 (rounded off)

Gideon has a rectangular garden with an area of 19.6 square feet. If the length of the garden is 4.3 feet, what is the length of
Allushta [10]

The length of the diagonal of the garden with 19.6 square feet and 4.3 length is : 6.3 feet

<h3>What is a rectangle?</h3>

A rectangle is a quadrilateral with four sides and four vertices  each of angle 90°.

Analysis:

Area of rectangle: 19.6 square feet

length of one side = 4.3 feet

width of one side = Area/length = 19.6/4.3 = 4.6 feet

the diagonal and width and length of a rectangle for a right angle triangle.

To find the diagonal, we use Pythagoras theorem

(diagonal)^{2} = (length)^{2} + (width)^{2}

(diagonal)^{2} = (4.3)^{2} + (4.6)^{2}

(diagonal)^{2} = 39.7

diagonal = \sqrt{39.7} = 6.3 feet

in conclusion, the diagonal of the rectangular garden is 6.3 feet

A cup of raw Arborio rice weighs 7 ounces. One cup will serve 1 people. Arborio rice is purchased in 2-pound boxes for $1.99. Ho
kow [346]

The rice will cost $17.6  for serving 40 people

<h3><u>Solution:</u></h3>

We need to determine the cost of serving 40 people with rice

Arborio rice is purchased in 2-pound boxes for $1.99

The price of 1 pound box will be \frac{\$ 1.99}{2}=\$ 0.995

1 Pound (lb) is equal to 16 ounces (oz)

Therefore, the price of 16 ounces is  $0.995

A cup of raw Arborio rice weighs 7 ounces and it serve 1 people

\begin{array}{l}{\text { The cost per person is } \frac{\$ 0.995}{16} \times 7=\$ 0.44} \\\\ {\text { The cost for serving } 40 \text { people }=\$ 0.44 \times 40=\$ 17.6}\end{array}

Therefore rice will cost $17.6  for serving 40 people
