Helene's marching band needs more to travel to a competition. Band members have raised $520. They need to raise a total of $1,630. Enter and solve an equation to find how much money they need. Show that your answer is reasonable. Let m represent your variable.

Answer:

About 95 miles

Step-by-step explanation:

Let's set up a proportion using the following set up:

miles / gallons = miles / gallons

We know the car can travel 38 miles on 2.4 gallons of gas.

38 miles / 2.4 gallons = miles/ gallons

We don't know how far the car can travel on 6 gallons. Therefore, we can say the car travels x miles on 6 gallons of gas.

38 miles / 2.4 gallons = x miles /6 gallons

38/2.4=x/6

We want to find x (miles for 6 gallons). Therefore, we must isolate x.

x is being divided by 6. The inverse of division is multiplication. Multiply both sides by 6.

6*(38/2.4)=(x/6)*6

6*(38/2.4)=x

6*15.8333333=x

94.9999998=x

Let's round to the nearest whole number. The 9 in the tenth place tells us to round up.

95 ≈x

x ≈95 miles

The car can travel about 95 miles on 6 gallons of gas.

Answer: 20

Step-by-step explanation:

x+y=5

x-y=4

---------

x+y=5

x=4+y

--------

(4+y)+y=5

4+y+y=5

 4+2y=5

      2y=1

        y=0.5

        x=4.5

---------

x²-y²=(4.5)²-(0.5)²=20.25-0.25=20

Answer: Value of B= 75  Basketball cards

Step-by-step explanation:

STEP 1

let number of cards Steve has be =a

let number of cards Claire has be =b

STEP 2

Steve has a= 84 basketball cards

Claire has 7 times less than Steve = 84 /7 = 12=b

STEP 3

if Claire buys 63 more cards

The present value of card Clare now has = 12 +63 = 75 basket ball cards=b

Answer:

4/9

Step-by-step explanation:

To simplify this fraction, we can find the factors for each number and then take an equal amount out (divide).

Two factors that make up 36 are 4 and 9. Two factors that make up 81 are 9 and 9. Therefore, because 9 is a common factor between the two, we can divide both terms by 9 and simplify the fraction.

36/9 = 4

81/9 = 9

The new fraction is 4/9.

Answer:

54 = 2×3^3

Step-by-step explanation:

Factor the following integer:

54

Hint: | Is 54 divisible by 2?

The last digit of 54 is 4, which means it is even. Therefore 54 is divisible by 2:

54 = 2 27:

54 = 2×27

Hint: | Now try to factor 27. Is 27 divisible by 2?

27 is not divisible by 2 since 27 is odd and 2 is even:

54 = 2×27 (27 is not divisible by 2)

Hint: | Is 27 divisible by 3?

The sum of the digits of 27 is 2 + 7 = 9, which is divisible by 3. This means 27 is divisible by 3:

27 = 3 9:

54 = 2×3×9 (9 is not divisible by 2 since 27 is not)

Hint: | Now try to factor 9. Is 9 divisible by 3?

9 = 3 3, which means 9 is divisible by 3:

9 = 3 3:

54 = 2×3×3×3 (3 is not divisible by 2 since 9 is not)

Hint: | Now try to factor 3. Is 3 prime?

No primes less than 3 divide into it. Therefore 3 is prime:

54 = 2×3×3×3

Hint: | Express 54 as a product of prime powers.

There is 1 copy of 2 and 3 copies of 3 in the product:

Answer: 54 = 2×3^3

Answer:

b.  area = 18 square units

Step-by-step explanation:

area of a triangle = 1/2 * base * height

area = 1/2 (6+3) + (6-2)

area = 1/2 * 9 * 4

area = 18 square units

therefore the answer is b.

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

So you already know that 34 is 34 stories in length.

Positive means: up, forward

Negative means: down, backward

Since the elevator is going down 34 stories, it is negative.

An elevator ride down 34 stories can be represented as -34 or negative 34.

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

The required  integer is -34.

It is required to find the integer.

An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Zero is not a fraction or decimal of any number. It is neither positive nor negative.

Given:

Positive means: up, forward

Negative means: down, backward

Since the elevator is going down, the situation is represented by a negative integer. Since it goes down 34 stories, then it is represented by the integer −34.

Therefore, the required  integer is -34.

Answer:

  0.222(repeating) = 2/9

Step-by-step explanation:

To convert a percentage to a decimal, divide by 100%.

  22.2%(repeating)/100% = 0.222(repeating)

__

To convert a repeating decimal to a fraction, first multiply it by 10 the the power that is equal to the number of repeating digits. Here, we have 1 repeating digit, so ...

  x = 0.222(repeating)

  10^1 · x = 10x = 2.222(repeating)

Now subtract the original. The repeating parts cancel.

  10x -x = 2.222(repeating) - 0.222 repeating = 2

  9x = 2

  x = 2/9 . . . . . divide by the coefficient of x

The decimal is 0.222(repeating).

The fraction is 2/9.

Answer:

5 : 2

Step-by-step explanation:

Given that:

Number of gumdrops = 420

Number of chocolate bars = 280

Total Number of candies = 700

To find:

The ratio of candies to chocolate bars = ?

Solution:

First of all, let us discuss the method to find the ratio of any two quantities.

Suppose, we need to find the ratio of two numbers [tex]p[/tex] and [tex]q[/tex].

Then to find the ratio [tex]p:q[/tex] , we need to divide p by q and represent it in the simplest form [tex]\frac{a}{b}[/tex] such that a and b can not be divided further.

Here, to find the ratio of candies to chocolate bar:

[tex]Ratio = \dfrac{\text{Number of candies}}{\text{Number of chocolate bars}}\\\Rightarrow \dfrac{700}{280}[/tex]

Here, we can simplify the fraction by dividing the numerator and denominator by 10 first:

[tex]\dfrac{70}{28}[/tex]

Now, let us divide the numerator and denominator by 14:

[tex]\dfrac{5}{2}[/tex]

So, the ratio is 5 : 2

Step-by-step explanation:

In place value, the digits of a large number are grouped in threes with the values arranged from left to right for example from left to right, e can have;

...billion...million...thousands...ones

For the international system, the place value chart can be written as follows;

Millions [tex]{}[/tex]                              Thousands                           Ones

Hundred

HM [tex]{}[/tex]    TM [tex]{}[/tex] M           HT      TT       U                        H      T        U

Where;

HM = Hundred million

TM = Ten million

M  = Million

HT = Hundred Thousand

TT  = Ten Thousand

T =Thousand

HT = Hundred

TT  = Ten

T or U =Ones or units

The cube of 47 is given as follows;

47³ = 103823

Therefore, the digit in the unit place of the cube of 47 is given as follows;
