Answer:

$3375 money would the student council have in four years if they invest $3000 at 5% interest compounded yearly.

Step-by-step explanation:

We are given:

Principal Amount = $3000

Interest Rate r = 5% or 0.05

n=1 (compounded yearly)

Years t= 4

We need to find future value (A)

The formula used is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Putting values in formula and finding future value A

[tex]A=P(1+\frac{r}{n})^{nt}\\A=3000(1+\frac{0.05}{1})^{1*4}\\A=3000(1+0.05)^4\\A=3000(1.05)^4\\A=3000(1.215)\\A=3375[/tex]

So, $3375 money would the student council have in four years if they invest $3000 at 5% interest compounded yearly.

Answer:

I got you lol

Step-by-step explanation:

Let's say you want to calculate the GCD and LCM of two numbers: 12 and 28. First, determine the prime factorizations of 12 = 2 × 2 × 3 and 28 = 2 × 2 × 7. The GCD is the string that is present in both sets of factorizations, i.e., 2 × 2 = 4. The LCM is the greatest power of all exponents;  2 × 2 × 3 × 7 = 84.

simply put, The Least Common Multiple (LCM) of two integers a and b, usually denoted by LCM (a, b), is the smallest positive integer that is divisible by both a and b.

GCD is the largest number that divides 2 numbers equally and gives remainder 0.

Another way to identify the domain and range of functions is by using graphs.

Step-by-step explanation:

Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

=154ft(nearest whole number)

Step-by-step explanation:

The height, h in feet, of a rocket is given by, where t is time in seconds.

[tex]h=-16t^2+64t+190[/tex] ...(1)

We need to find the maximum height of the rocket and find the time the rocket was in the air. For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]

[tex]\dfrac{d(-16t^2+64t+190)}{dt}=0\\\\-32t+64=0\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]

So, it will reach its maximum height in 2 seconds.

Now put t = 2 in equation (1) as follows :

[tex]h(2)=-16(2)^2+64(2)+190\\\\=254\ \text{feet}[/tex]

So, the maximum height of the rocket and find the time the rocket was in the air is 254 feet and 2 seconds respectively.

Explanation:

Check out the diagram below.

Segment BD cuts angle EBC in half

So the two smaller pieces DBC and DBE are congruent. Let's call them x.

Let's make y = angle EBA.

Note how the diagram shows the angles x, x, and y forming a straight angle. So we can say

x+x+y = 180

2x+y = 180

y = -2x+180

We'll use this later.

For now, focus on triangle DEB. Angle E is 90 degrees and angle B is x.

D+E+B = 180

28+90+x = 180

x+118 = 180

x = 180-118

x = 62

Which means

y = -2x+180

y = -2*62+180

y = -124+180

y = 56

Now focus on triangle BEA. We have B = 56, E = 90 and A = z

B+E+A = 180

56+90+z = 180

146+z = 180

z = 180-146

z = 34

which is the measure of angle A.

Answer:

For 6 days

Step-by-step explanation:

Here, we want to find the number of days at which Australia will have a bigger temperature or the same temperature as US

95 degrees, decreasing at 4 degrees per day

40 degrees, increasing at a rate of 5 degrees per day

let the number of days be x

In x days, temperature of Australia will be 95-4x

In x days, temperature of US will be 40 + 5x

For the temperature to be same;

40 + 5x = 95 - 4x

95-40 = 5x + 4x

9x = 55

x = 55/9

x = 6.111 which is approximately 6

For 6 days, the temperature in Australia will be warmer , on the 7th day, the US temperature becomes warmer

Answer:

40 rubber bands are needed

5 rubber bands will be left from 5 bags of of rubber band

Step-by-step explanation:

Each student will need five rubber bands.

There are eight students

Total rubber bands needed = rubber bands per student × number of students

= 5 × 8

= 40

Total rubber bands needed = 40

Rubber bands come in bags of nine.

Number of bags needed = Total rubber bands needed / number of rubber bands in each bag

= 40 / 9

= 4.44 bags

It is impossible to get decimal number of rubber bands bag, so, the next whole number after 4 is 5

5 rubber bands bags will be bought which = 5 × 9

= 45 rubber bands

Only 40 rubber bands are needed

Left over rubber bands = 45 - 40

= 5 rubber bands

Answer:

[tex]90,000^{3}[/tex] (90,000 cubed)

Step-by-step explanation:

150 x 30 x 20

Answer:

(2,4)

Step-by-step explanation:

Equation 1:

x+y=6(for the 6 times they scored)

x=-y+6

Equation 2:

7x+3y=26 (for the 7 point touchdowns, and 3 point field goals.)

7(-y+6)+3y=26(replace x with -y+6)

7y+42+3y=26(distrubite property)

-4y+42=26

-4y= -16

y= 4

Now that we know that y is equal to 4:

x+4=6

x=2

The number of touchdowns and field goals that the home team scored are 2 and 4 respectively

If the team scored six-time, this is expressed as;

x + y = 6

y = 6 - x ........................ 1

If in the football game, all for the home team's 26 points came from 7-point touchdowns and 3-point field goals, this is expressed as;

7x + 3y = 26 ...................2

Substitute equation 1 into 2 to have:

7x + 3(6-x) = 26

7x + 18 - 3x = 26

4x + 18 = 26

4x = 26 - 18

4x = 8

x = 2

Recall that y = 6 - x

y = 6 - 2

y = 4

Hence the number of touchdowns and field goals that the home team scored are 2 and 4 respectively
