Answer:

30 cm

Step-by-step explanation:

set up a proportion of insect height over its shadow equals flower height over its shadow, then cross-multiply

Can there be more than one mean or mode in a math problem??
astraxan [27]

Math. When no number occurs more than once in a data set, there is no mode. If each of two numbers occurs twice, we say the set is bimodal.

Jimmy rolled a die 90 times and recorded the results. He got a one 15 times, a two 22 times, a three 18 times, a four 11 times,
vovikov84 [41]

Since in Jimmy's 90 times die roll six appeared 11 times, so the probability of face of sixes appearing is: \frac{11}{90}.

Thus , when the die is rolled 1500 times then it is obvious that the number of times the face of six will appear will also increase proportionately.

This proportionate increase in the number of times the face of six will appear will be given thus:

If six appears 11 times in 90 rolls then to find how many times it will appear in 1500 rolls is calculated as \frac{11}{90}=\frac{x}{1500} where x is the number of times the face of six will appear.

Thus, expression gives:

x=\frac{11}{90}\times 1500=\frac{11\times 50}{3}=\frac{550}{3}  \approx 183

Therefore, Jimmy can six's approximately 183 times if he rolled the die 1500 times.

​ Quadrilateral ABCD ​ is inscribed in this circle.<br><br><br><br> What is the measure of angle C?
ivann1987 [24]

Answer:

The measure of angle C = 92°

Step-by-step explanation:

The sum of opposite angles of cyclic quadrilateral is 180°

From the figure we can see that,quadrilateral ABCD ​ is inscribed in a circle.

<u>To find the value of x</u>

m<B + m<D = 180°

(x + 10 ) + ( x + 24 ) = 180

x + 10 + x + 24 = 180

2x + 34 = 180

2x = 180 - 34 = 146

x = 146/2 = 73

<u>To find the measure of <A</u>

m<A = x + 15

x = 73

m<A = 73 + 15 = 88°

<u>To find the measure of <C</u>

m<C + m<A = 180°

m<C + 88 = 180

m<C = 180 - 88 = 92°

Therefore the measure of angle C = 92°
