Answer:

26 roses

Step-by-step explanation:

89-11 = 78

78/3 = 26

Answer:

B

Step-by-step explanation:

Answer:

50%

Step-by-step explanation:

Let the total number of trees be T and suppose that this is made up of eucalyptus trees E and other kinds of trees, O.

Then E+O=T, and since 99% of the trees are eucalyptus trees, EE+O=0.99.

Therefore

0.99E+0.99O=E

0.01E=0.99O

E=99O.

Suppose we reduce the number of eucalyptus trees by some amount x and that the remaining number of eucalyptus trees are now 98% of the total trees.

Then we would have E−x(E−x)+O=0.98.

Therefore,

0.02(E−x)=0.98O

0.02E−0.02x=0.98O

0.02x=0.02E−0.98O

x=E−50(0.98)O

x=E−49O

x=E−49(E99)

x=5099E≈0.505050...×E.

So we end up removing a little over half of the eucalyptus trees. EDIT: Forgot to mention - removing 50.505050...% of the eucalyptus trees means that we are removing 0.50505050....×0.99T which is 0.5T or half the trees in the neighborhood.

Answer:

R = 11.42º

Step-by-step explanation:

sin∅ = opp/hyp

sinR = 20/101

R = arcsin20/101

Use calculator

Rounded

R = 11.42º

Yes it is

Answer:

[tex]Cindy = 30[/tex]

[tex]Hao= 10[/tex]

[tex]Raymond = 5[/tex]

Step-by-step explanation:

Given

Represent each withe first letter of their name;

So:

[tex]C = 3H[/tex]

[tex]R = \frac{1}{2}H[/tex]

[tex]\frac{C + R + H}{3} = 15[/tex] --- the average of books

Required

The number of book each has

Substitute [tex]C = 3H[/tex], [tex]R = \frac{1}{2}H[/tex] in [tex]\frac{C + R + H}{3} = 15[/tex]

[tex]\frac{3H + \frac{1}{2}H + H}{3} = 15[/tex]

Multiply both sides by 3

[tex]3 * \frac{3H + \frac{1}{2}H + H}{3} = 15 * 3[/tex]

[tex]3H + \frac{1}{2}H + H = 45[/tex]

Take LCM and solve

[tex]\frac{6H + H + 2H}{2}= 45[/tex]

[tex]\frac{9H}{2}= 45[/tex]

Multiply both sides by 2/9

[tex]\frac{2}{9} * \frac{9H}{2}= 45 * \frac{2}{9}[/tex]

[tex]H= 45 * \frac{2}{9}[/tex]

[tex]H= 5 * 2[/tex]

[tex]H= 10[/tex]

[tex]C = 3H[/tex]

[tex]C = 3 * 10[/tex]

[tex]C = 30[/tex]

[tex]R = \frac{1}{2}H[/tex]

[tex]R = \frac{1}{2} * 10[/tex]

[tex]R = 5[/tex]

Step-by-step explanation:

for the triangle:

1.9x8/2= 7.6mi (this is area)

perimeter=17mi

for the trapezoid:

area= 18.36+13.6=31.96yd

perimeter=24.1yd

Answer:

336 plants

Step-by-step explanation:

Area of a right triangle= 1/2•base•height

A= 1/2bh

A= 1/2•7•24

A= 84 yards^2

# of plants= yards^2•4

84•4= 336 plants

Answer: 1/4

Step-by-step explanation:

He has a 1 in 4 chance to roll a number less than three since there are 3 consonants and 1 vowel and all sides are the same size

We can write that the probability that Riley rolls a number less than 3 and lands on a consonant as 1/2.

Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes. Probability is a measure of how likely an event is going to happen.

Given is that Riley is playing a game that requires rolling a number cube numbered 1-6 and spinning with 3 consonants and 1 vowel. The sections of the spinner are all the same size.

It is asked to find the probability that Riley rolls a number less than 3 and lands on a consonant.

We can write the probability that Riley rolls a number less than 3 and lands on a consonant as -

P{number less than 3 and lands on a consonant} = n{F}/n{T}

P{number less than 3 and lands on a consonant} = n{F}/n{T}

P{number less than 3 and lands on a consonant} = 5/10

P{number less than 3 and lands on a consonant} = 1/2

Therefore, we can write that the probability that Riley rolls a number less than 3 and lands on a consonant as 1/2.

Answer:

1/216

Step-by-step explanation:

Hi, the probability of rolling it once is 1/6, twice in a row results in multiplying 1/6 by 1/6.

Therefore, three times means using the formula: (1/6)^3

Which gives us the fraction 1/216
