ax^2+bx+c=0  \\ \\
x^2-13x+30 = 0 \\ \\ D=b^2-4ac = 169-120=\sqrt{49} =7 \\ \\ x_{1/2} =  \frac{-b^2+/-\sqrt{D}}{2a} = \frac{13+/-7}{2*1} \\ \\ x_1 = \frac{13+7}{2} = 10 \\ \\ x_2 = \frac{13-7}{2} = 3

Snowcat [4.5K]
I am not sure what the question is here. I can tell you how to find the percent of kids that developed influenza in that class. We can compare it to the 20% of students nationwide. There could many different questions that stem from the piece of information you gave.

To find the percent of kids that developed influenza in that class do 6÷15 which gives you
.4 and written as a percent would be 40%.

Please message me if you have any questions! Hope this helps!

mina [271]

Answer:

105.876373581

Step-by-step explanation:

8.563 + 4.8292 = 13.3922

13.3922 × 9.183 = 122.9805726

122.9805726 ÷ 1.192 = 103.171621309

103.171621309 ÷ 1.192 = 86.5533735811

86.5533735811 + 19.323 = 105.876373581

PLEASE HELP!!! TIMED QUESTION!!! NOT A TEST NOR QUIZ!!!!
natita [175]

Answer:

LCD=280

Step-by-step explanation:

Equivalent Fractions with the LCD

1/8 = 35/280

2/7 = 80/280

4/5 = 224/280

Solution:

Rewriting input as fractions if necessary:  1/8, 2/7, 4/5

For the denominators (8, 7, 5) the least common multiple (LCM) is 280.

LCM(8, 7, 5)

Therefore, the least common denominator (LCD) is 280.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 35/35 = 35/280

2/7 = 2/7 × 40/40 = 80/280

4/5 = 4/5 × 56/56 = 224/280
