Yolanda's Flower Shop sells long-stem roses for $5 each. In addition, the
shop charges a $15 shipping fee. How many roses can Santo purchase if he
plans to spend $90?

Answers

Answer:

15

Step-by-step explanation:

5x + 15 <= 90

5x<=75

x=15

Answer:

15 roses

Step-by-step explanation:

90 (Amount Santo wants to spend)

15 (Shipping fee)

You first subtract Shipping Fee from the total amount Santo wants to spend

90-15=75

Next it's time to figure out how many roses he can buy with the $75

Each roses is $5, so you divide the left over money after shipping by the price of the rose.

75÷5=15

Answers

Answer: 54

Step-by-step explanation:

1) First, we need to find what 'x' is. We know that the exterior angles of a triangle equal to 360. So, we will add up all the expressions and set them equal to 360.

7x-2 + 9x-31 + 4x +33 = 360.

2) We will add all the like terms, which will give us: 20x + 0 = 360. We don't need to add the 0.

3) Now, we will isolate the 'x' by dividing 360 by 20 and we will get: x= 18.

4) To find the measure of angle DCE, we just have to substitute x in '7x-2' with 18, which then would equal to: 124.

5) Now, that we have the adjacent angle of DCE, we just have to subtract 124 from 180, and we will get the answer.

6) Angle DCE equals to 54.

To the nearest square centimeter, what is the area of the shaded sector in he circle shown below? Radius= 12 cm, angel = 110 degrees

Answers

Answer:

138.23 cm²

Step-by-step explanation:

The formula for the area of a sector is given as:

θ/360 × πr²

θ = 110°

Radius = r = 12 cm

Hence

Area of a sector = 110/360 × π × 12²

= 138.23007676 cm²

Approximately, Area of a sector = 138.23 cm²

Winston has a savings in a bank and was surprised that his money

interest rate compounded bimonthly. How much was his sayings at the start?​

Answers

The initial saving of the Winston was $55952.48

Compound Interest

Compound interest is when you receive interest on both your interest income and your savings.

According to the question given,

Let the initial savings amount be P

We know Compound interest =

[tex]A = P(1+\frac{r}{n} )^{nt}[/tex]

Where,

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest is applied per year

t = number of time periods elapsed

Given,

A = $65000

t = 3 years

r = 5% = 0.05

n = 2 *12 = 24

So

65000 = P(1 + (0.05/24))^72

P =  $55952.48

Therefore the initial savings was  $55952.48

Ms. Michaels surveyed her class on whether they preferred free time at the beginning of class or at the end of class. If the ratio of students who prefer free time at the beginning of class to students who prefer free time at the end of class is 13 over 17, what does the ratio 13 over 17 represent?

Answers

Answer:

Step-by-step explanation:

Based on the fact that Ms. Michaels surveyed her class on whether they preferred free time at the beginning of class or at the end of class and found that students who prefer free time at the end of class are 12 over 19, the thing which the ratio 12 over 19 represents is C. 12 students prefer free time at the beginning of class, and 19 students prefer free time at the end of class.

What is a Ratio?

This refers to the quantitative relation that is used to show the relation between two variables, which shows the number of times one is contained in the other.

Hence, it can be seen that based on the result of the survey by Ms. Michaels about the preference of the students about free time at the beginning of class or at the end of class, the meaning of the ratio is that 12 students prefer free time at the beginning of class, and 19 students prefer free time at the end of class.

the ratio 13 over 17 represents how many students preferred free time at the beginning of class to how many students preferred free time at the end of class.a little extra: more people want free time at the end of class than at the beginning

Seven netball teams played in a school's competition. Each team had 7 players. If 3/7 of the number of players were disqualified for poor conduct, how many pupils were qualified?

Answers

28 players.

We know that there are seven teams with seven players each. This is 49 players total. We know that the fraction 3/7 must be equal to x/49. Since we multiples the denominator by 7, we have to multiply the numerator by 7 too. This is 3 x 7 =21. Therefore, 21 out of the 49 players were disqualified. However, the question wants to know how many qualified, so we must subtract. 49-21=28 players. Hope this helped!

2. Tell whether the segment lengths form an acute, right, or obtuse? 9, 12, 17​

Answers

Answer:

obtuse angled triangle

Step-by-step explanation:

Given 3 segments , say a, b and c , with c the longest then

• If a² + b² = c² ⇒ right triangle

• If a² + b² > c² ⇒ acute triangle

• If a² + b² < c² ⇒ obtuse triangle

Here c = 17 and 17² = 289

9² + 12² = 81 + 144 = 225

Since 225 < 289 , then triangle is obtuse

How do you find the difference between two different numbers?

Answers

Subtract the smaller of the two numbers from the larger of the two numbers to discover the difference between them.

Subtract the smaller of the two numbers from the larger of the two numbers to discover the difference between them. The difference between the two numbers is the sum's product.

Subtracting two integers from each other is a type of subtraction.

The process for determining the difference between two decimals and two whole numbers is the same.

We only add a new step.

Finding the difference between 8.967 and 7.2, for instance, could appear more difficult.

To give them all the same amount of decimal places, we must first convert each decimal.

7.2 becomes 7.200 as a result.

The computation may now be done as before:

8.967 - 7.200 = 1.767

Therefore, there is a 1.767 discrepancy between these figures.

In order to find the difference between two fractions, simplify and find the lowest common denominator of each fraction.

Answers

Therefore , the solution of the given problem of interest rate comes out to be the amount after 5 years is A  ≈ 364.996.

Define interest rate.

With the help of an interest rate, you can determine how much borrowing will cost you and how much saving will yield. As a result, the interest rate is the cost of borrowing money and, if you're a borrower, it's expressed as a percentage of the total loan amount. An amount, expressed as a percentage of the loan amount, that a borrower is required to pay to a lender as interest during the term of a loan.

Here,

Given : Principal amount : $300

rate of interest :  4%

and time =5 years

Thus , to find the amount after 5 years as compounded

We use , the formula:

=> A = P

=> A  =

=> A =    

=> A  ≈ 364.996

The amount after 5 years with compound interest rate is option(A)  = $365. 00.

What is called interest rate?

The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR (APR).

A savings account or certificate of deposit earnings at a bank or credit union may also be subject to an interest rate (CD). The interest received on these deposit accounts is measured in annual percentage yields (APY).

Given : Principal amount : $300

rate of interest :  4% (compounded yearly)

time =5 years

Thus , to find the amount after 5 years as compounded we use , the formula:

=> A = P(1 + r/100)^t.

=> A = $300 (1 +4/100)^5

=> A = $300 (104/100)^5

=> A = $300 (1.04)^5

=> A = $300 * 1.2167

=> A = $365.00
