Ratio means only one thing but I think what you meant was 3 examples of a ratio. In that case three examples would be: 2:3, 2 to 3, 2/3

natka813 [3]

Answer:

The amount invested at 4% per year was $3,000

The amount invested at 4.5% per year was $6,000

The amount invested at 2.5% per year was $1,000

Step-by-step explanation:

Let

x -----> the amount invested at 4% per year

2x ----> the amount invested at 4.5% per year

10,000-3x -----> the amount invested at 2.5% per year

we know that

The interest earned by the amount invested at 4% per year plus the interest earned by the amount invested at 4.5% per year plus the interest earned by the amount invested at 2.5% per year must be equal to $415

$4\%=4/100=0.04$

$4.5\%=4.5/100=0.045$

$2.5\%=2.5/100=0.025$

$0.04x+0.045(2x)+0.025(10,000-3x)=415$

Solve for x

$0.04x+0.09x+250-0.075x=415$

$0.055x=415-250$

$0.055x=165$

$x=\$3,000$

therefore

The amount invested at 4% per year was $3,000

The amount invested at 4.5% per year was $6,000

The amount invested at 2.5% per year was $1,000

Bella saw that 7:11 people brought an umbella to the beach. There were 99 peopel there. How many of them did not have a beach um

Rina8888 [55]

Answer:

36 people of them did not have a beach umbrella.

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

Let x represents the number of people did not have a beach umbrella.

As per the statement:

Bella saw that 7 : 11 people brought an umbrella to the beach.

Out of 11 people, only 7 people brought an Umbrella to the beach.

Remaining people did not brought an Umbrella to the beach = 11 -7 = 4 people

It is also given that there were 99 people there.

then by definition of proportion:

$\frac{4}{11} = \frac{x}{99}$

By cross multiply we have;

$99 \times 4 = 11x$

Divide both sides by 11 we get;

$x = 9 \times 4$

Simplify:

x = 36 people.

Therefore, 36 people of them did not have a beach umbrella.

In RSM camp, there are four counselors for every fifty seven students and three teachers for every five counselors. Chapter Refe

max2010maxim [7]

The number of students attending the camp that summer is 380 students

Step-by-step explanation:

There are four counselors for every fifty seven students

There are three teachers for every five counselors

Ms. Rifkin asked all 16 teachers present at the camp to attend a

teachers meeting

To solve this question we will use the ratio

The given is:

1. 4 counselors for every 57 students

2. 3 teachers for every 5 counselors

3. There are 16 teachers

At first let us find the 16 teachers are for how many counselors

∵ 3 teachers : 5 counselors

∵ 16 teachers : x counselors

∴ $\frac{3}{5}=\frac{16}{x}$

By using cross multiplication

∴ 3x = 16 × 5

∴ 3x = 80

Divide both side by 3

∴ x = $\frac{80}{3}$

Then let us find the $\frac{80}{3}$ counselors are for how many students

∵ 4 counselors : 57 students

∵ $\frac{80}{3}$ counselors : y students

∴ $\frac{4}{57}=\frac{80/3}{y}$

By using cross multiplication

∴ 4y = 57 × $\frac{80}{3}$

∴ 4y = 1520

Divide both sides by 4

∴ y = 380 students

The number of students attending the camp that summer is 380 students

H(x) = 3x + 3<br> g(x)=-4x+1<br> Find (h+ g)(10)

Ratling [72]

Answer:

(h + g)(10) = -6

Step-by-step explanation:

Step 1: Define

h(x) = 3x + 3

g(x) = -4x + 1

Step 2: Find (h + g)(x)

(h + g)(x) = 3x + 3 + -4x + 1

(h + g)(x) = -x + 4

Step 3: Substitute and Evaluate

(h + g)(10) = -10 + 4

(h + g)(10) = -6
