Answer:

Step-by-step explanation:

Let the probability of picking an orange = P(O), and the probability of picking a strawberry = P(S),

Based on the question, he picked an orange first and the probability of picking that is

P(O) = 12/50

Then he picked a strawberry on the second pick, the probability of picking the strawberry is P(S) and we'll find that later.

The probability of picking orange then strawberry with replacement is

P(O) × P(S) = 9/125

Substitute the P(O)=12/50,

12/50 × P(S) = 9/125

P(S) = 3/10

Then by finding the number of strawberry candies, we'll just have to multiply P(S) with the total number of candies, i.e.

Number of strawberry candy

= 3/10 × 50

= 15

The high school has 26 teachers and 546 students. What is the ratio of teachers to students?

skelet666 [1.2K]

Answer:

1:21

Step-by-step explanation:

Easiest trick way to do this is do 26/546 on your calculator (if you got a scientific one) this would simplify this to its lowest fraction which can be converted into a ratio in this case the ratio of teachers to students is 1:21

If an item costs $45 and we must pay 6% sales tax, how much will we pay for the item?

Gennadij [26K]

$47.70

$45 with 6% sales tax

6%=.06

To find total amount multiply by 1.06 or multiply by .06 and that is tax amount and then add it to the $45

$45*.06=2.70 amount of tax

$45*1.06=47.70 total amount paid

Any questions feel free to ask. Have a great day!

What angle has the same sine value between 0-180? as Sin 24

Inessa05 [86]

Answer:

$Sin156$

Step-by-step explanation:

Given

$Sin24$

Required

Find equivalent between 0 to 180;

Let 24 be represented by $\theta$

So, $\theta = 24$

From Trigonometry ratios;

$Sin\theta = Sin(180 - \theta)$ where $0\leq \theta \leq 180$

Recall that $\theta = 24$

So, we have to substitute 24 for $\theta$ in the above expression.

This gives

$Sin24= Sin(180 - 24)$

Subtract 24 from 180

$Sin24= Sin156$

Hence, the equivalent of $Sin24$ is $Sin156$

A two digit number when read from left to right to right consiststs of consecutive integers. the nmber is six more than for time

Solnce55 [7]

I suppose you want to know such number. Since we have a two digit number consisting of two consecutive integers, the only possible numbers are:

$12,23,34,45,56,67,78,89$

Since we sorted all the cases out, we simply have to check which one satisfies the requirement. For each number, we'll write four times the the sum of its digits, and add 6, hoping to get the original number.

$\text{Number: } 12,\ \ 4\times \text{sum of digits: } 12\ \ \text{plus six: } 18\neq 12$

$\text{Number: } 23,\ \ 4\times \text{sum of digits: } 24\ \ \text{plus six: } 30\neq 23$

$\text{Number: } 34,\ \ 4\times \text{sum of digits: } 28\ \ \text{plus six: } 34$

So, the answer is 34.

What is the area of this trapezoid?

Sonbull [250]

Find the area of the square first
Area = Length x Width
Area = 12 x 9
Area = 108

Find the area of the right triangles
Area = 1/2(Length x Base)
Area = 1/2(9 x 2)
Area = 1/2(18)
Area = 9
Since there is 2 triangles multiply by 2
9 x 2 = 18

Now add
108 + 18 = 126
126 is your area
