There is a bag with 50 popsicles inside. 5
are red, 15 are orange, 12 are blue, 8 are
yellow and 10 are purple. If you were to
grab one popsicle from the bag, what is
the probability that it is purple?
Answer:
25%
Step-by-step explanation:
We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.
SMART PPL PLEASE HELP ,Explain how you know the expression represents the area of shaded part of the rectangle.
Answer:
6(m-2)
Step-by-step explanation:
Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-
Answer is: 6(m-2)
Answer:
6(m-2)
Step-by-step explanation:
it is 6(m-2) because you would do the whole length of m minus 2.
You have $350 dollars in your savings account the account pays an interest rate of 2.25% how much will you earn in interest this year?
Answer:tttaergfzgsfbvzfsbzfzbfs
The amount of interest that you earn after a year will be $7.875.
What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
[tex]\rm A = P \left (1 + \dfrac{r}{n} \right ) ^{nt}[/tex]
Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.
You have $350 in your savings account, which has a 2.25% interest rate.
Then the amount of interest that you earn after a year will be given as,
I = A - P
I = $350(1 + 0.0225) - $350
I = $350 (1.0225) - $350
I = $357.875 - $350
I = $7.875
The amount of interest that you earn after a year will be $7.875.

Find the indicated term of each sequence by repeatedly multiplying the first term by the common ratio.
Enter your answer to 5 decimal places if necessary. Use a calculator.
-40, 20,-10, ...; 5th term
The 5th term of the sequence is
Answer: -2 1/2
Step-by-step explanation:
First term = a = -40
Common ratio = 2nd term / First term = 20 / -40 = -1/2
5th term = ar⁴
5th term = -40 × (-1/2)⁴
5th term = -40 × 1/16
5th term = -2 1/2

Find the simple interest paid and the amount paid for the loan.
$4800 at 9.9% for 4 years
Answer:
$1900.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9.9%/100 = 0.099 per year,
then, solving our equation
I = 4800 × 0.099 × 4 = 1900.8
I = $ 1,900.80
The simple interest accumulated
on a principal of $ 4,800.00
at a rate of 9.9% per year
for 4 years is $ 1,900.80.

Please help.. Answer number 34 and 35. For number 34 find the measures of the numbered angles in each isosceles trapezoid. For number 35 find the measures of the numbered angles in each kite.
Answer:
33. m∠1 = 135°, ∠3 = 45°, ∠2 = 135°
34. m∠1 = 80°, m∠2 = 100°, m∠3 = 100°
35. m∠1 = 90°, m∠2 = 25°
Step-by-step explanation:
33. The given parameters of the isosceles trapezoid are;
The measure of one of the base angles = 45°
For an isosceles trapezoid, the base angles are equal, therefore, we have;
The measure of the other base angle = m∠3 = 45°
Similarly, m∠1 = m∠2
Also, we have;
The sum of the interior angles in a trapezoid = The sum of the interior angles in a quadrilateral = 360°
∴ 45° + m∠3 + m∠1 + m∠2 = 360°
By substituting the known values, we have;
45° + 45° + m∠1 + m∠2 = 360°
From m∠1 = m∠2, we have;
45° + 45° + m∠1 + m∠1 = 90° + 2·m∠1 = 360°
2·m∠1 = 360° - 90° = 270°
∴ m∠1 = 270°/2 = 135°
m∠1 = 135° = m∠2
Therefore, we have;
∠3 = 45°, ∠1 = 135°, ∠2 = 135°
34. The measure of the base angles = 80°
∴ The measure of the other base angle = m∠1 = 80°
m∠2 = m∠3
80° + m∠1 + m∠2 + m∠3 = 360°
∴ 80° + 80° + 2·m∠2 = 360°
m∠2 = (360° - (80° + 80°))/2 = 100°
m∠2 = 100° = m∠3
35. The kite comprises of two half isosceles triangles
The base angles of the right half isosceles triangle = 65°
The angle formed by the diagonals of the kite = 90° (Perpendicular diagonals theorem)
Therefore, m∠1 = 90°
The diagonals bisect the angles at the vertices (Kite theorem)
Therefore, we have;
65° + 90° + m∠2 = 180°
m∠2 = 180° - (65° + 90°) = 25°
m∠2 = 25°.

John wants to gain weight for his wrestling team so he can compete in a different weight class. He currently weighs 187 pounds, and is gaining weight at a rate of 1.5 pounds per week. Which equation below models this situation * number of weeks y = total weight (pounds )
Answer:
The equation would be 1.5w + 187 = y.
Step-by-step explanation:
1.5 lbs per week
already 187
The variable would be 'w'
so 1.5w +187 = y
