Cody has $700 in a savings account that pays 4% interest. what is the amount of simple interest he will learn in 2 years

Answers

Answer 1
Answer:

Answer:

The interest Cody gets in 2 years be $56 .

Step-by-step explanation:

Formula

Simple\ interest = (Principle* Rate* Time)/(100)

As given

Cody has $700 in a savings account that pays 4% interest .

Principle = $700

Interest = 4%

Time = 2 years

Put in the formula

Simple\ interest = (700* 4* 2)/(100)

Simple\ interest = (5600)/(100)

Simple interest = $ 56

Therefore the interest Cody gets in 2 years be $56 .
Answer 2
Answer: The answer is $56. I=P×R×T I=700×0.04×2 I=$56

3. The width and length of a rectangle areconsecutive integers. If the perimeter of
the rectangle is 142 inches, find the width
and length of the rectangle.​

Answers

Answer:

35 and 36

Step-by-step explanation:

If the smaller dimension is x, then the larger dimension is x + 1.  Therefore:

2x + 2(x + 1) = 142

2x + 2x + 2 = 142

4x = 140

x = 35

One dimension is 35, and the other dimension is 36.

Answer:

The dimensions of the rectangle are 35 inches by 36 inches.

Step-by-step explanation:

If the length and width are consecutive integers and L=n, then W=n+1 assuming the width is larger.

We are given the perimeter is 142 inches so: 2L+2W=142.

Substituting L=n and W=n+1 we have:   2(n)+2(n+1)=142.

Let's solve it:

2(n)+2(n+1)=142

Distribute:

2n+2n+2=142

Combine like terms:

4n+2=142

Subtract 2 on both sides:

4n=140

Divide both sides by 4:

n=140/4

n=35

Since L=n, then the length is 35 inches.

Since W=n+1, then the width is 36 inches.

The dimensions of the rectangle are 35 inches by 36 inches.

Step-by-step explanation:

Two fifths of the instruments in the marching band are brass, one third are percussion, and the rest are woodwinds. A. What fraction of the band are wood winds B. One half of the woodwinds are clarinets. What fraction of the band is clarinets c. one eighth of the brass instruments are tuba. If there are 240 instruments in the band, how many are tubas. To the brainly users answer one if you must I will give you a helpful point as we'll thanks

Answers

A. What fraction of the band are woodwinds?
First, find common denominators for the first two. Let's use 15.
6/15 is brass (5x3=15, and 2x3=6)
5/15 is percussion (3x5=15, and 1x5=5)
Now, we add the two and subtract them from the whole.
6/15 + 5/15 = 11/15
15/15 - 11/15 = 4/15
4/15 of the band is woodwinds.

B. One half of the woodwinds are clarinets. What fraction of the band is clarinets?
To find this, we take our 4/15 and divide it by two. Thankfully, the numerator is an even number, so it splits in half easily.
4/15 divided by 2 = 2/15
2/15 of the band is clarinets.

C. One eighth of the brass instruments are tubas. If there are 240 instruments in the band, how many are tubas?
First, find 1/8 of the number of brass instruments.
6/15 of the band is brass.
We need to make this an equivalent fraction that is divisible by 8.
Both 6 and 8 go into 24, so we'll multiply our fraction by 4, since 6x4=24
The new fraction is
24/60
Now, we divide that fraction by 8, to find 1/8 of the brass instruments.
24/8=3
3/60 of the band is tubas.
To find the number of tubas out of a 240 instrument band, we multiply the fraction of tubas by the whole band.
3/60 x 240 = 12
There are 12 tubas in the band.

Answers

we know that

The easiest way to find the number that makes the statement true is to substitute the given answers into the equation.

so

Part 1)

4.3-2x < x^(2) -2

a) For x=0

4.3-2*0 < 0^(2) -2

12 < -2 -----> is false

b) For x=1

4.3-2*1 < 1^(2) -2

10 < -1 -----> is false

c) For x=2

4.3-2*2 < 2^(2) -2

8 < 2 -----> is false

d) For x=3

4.3-2*3 < 3^(2) -2

6 < 7 -----> is true

therefore

the answer part 1) is the option D

x=3

Part 2)

6*7-5x+x^(2) \geq x^(3) +x^(2)

a) For x=5

6*7-5*5+5^(2) \geq 5^(3) +5^(2)

42 \geq 150 ----> is false

b) For x=6

6*7-5*6+6^(2) \geq 6^(3) +6^(2)

48 \geq 252 ----> is false

c) For x=4

6*7-5*4+4^(2) \geq 4^(3) +4^(2)

38 \geq 80 ----> is false

d) For x=3

6*7-5*3+3^(2) \geq 3^(3) +3^(2)

36 \geq 36 ----> is True

therefore

the answer Part 2) is the option D

x=3

Part 3)

we have

8*3-4x\ (\ )\ 7*(10-x)

For x=3

8*3-4*3\ (\ )\ 7*(10-3)

12\ (\ )\ 49

we know that

12 < 49

therefore

the answer Part 3)  is the option B

<

Part 4)

we have

9*4-2x\ (\ )\ 5*(11-x)

For x=8

9*4-2*8\ (\ )\ 5*(11-8)

20\ (\ )\ 15

we know that

20 > 15

therefore

the answer Part 4)  is the option B
