What is 21 over 4 written as a whole number

Answer:

7.56 liters

Step-by-step explanation:

Total amount of paint mix ordered by the painter = 18 gallons

42% of the paint mix is white.

Representing this as a fraction, [tex]\[\frac{42}{100}\] [/tex] of total paint mix is white.

To find the amount of white paint, we need to multiply this fraction with the total amount of paint mix.

[tex]\[= \frac{42}{100} * 18\] [/tex]

[tex]\[= \frac{756}{100}\] [/tex]

7-4=3

To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations. The two numbers are 7 and 4.

To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations.

Let's call the two numbers x and y. We can set up the following equations:

x + y = 11

x - y = 3

Now we can solve this system of equations by adding the two equations together:

(x + y) + (x - y) = 11 + 3

Simplifying, we get:2x = 14

Dividing both sides by 2, we get:x = 7

Now we can substitute this value of x back into one of the original equations to solve for y:7 + y = 11

Subtracting 7 from both sides, we get:y = 4

So, the two numbers are 7 and 4.

Answer:

First term: A(1) = 5

Fourth term: A(4) = 5 1/2

Tenth term: A (10) = 6 1/2

Step-by-step explanation:

Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:

A(n) = 5 + (n-1) (1/6)

First term:

A(1) = 5 + (1-1) (1/6)

A(1) = 5 + (0) (1/6)

A(1) = 5

Fourth term:

A(4) = 5 + (4-1) (1/6)

A(4) = 5 + (3) (1/6)

A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 (simplifying)

Tenth term

A(10) = 5 + (10-1) (1/6)

A(10) = 5 + (9) (1/6)

A (10) = 5 + 9/6 = 6 3/6 = 6 1/2 (simplifying)

Answer: he is right the answer is -2

Step-by-step explanation:

The common difference (d) is -2.

In an arithmetic sequence, the common difference (d) is the constant value by which each term differs from the previous term.

To find the common difference in the sequence 100, 98, 96, 94, 92..., we can observe the difference between consecutive terms:

98 - 100 = -2

96 - 98 = -2

94 - 96 = -2

92 - 94 = -2

We see that each term is decreasing by 2. Therefore, the common difference (d) is -2.

The actual rate of the mortgage is 5.27%.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Since, we're taking two mortgages for a total of $100,000 for 30 years,

Now, we can find the actual rate of the mortgage by finding the weighted average of the two rates.

Hence, The weights in this case will be the proportion of loan taken at each rate;

We have

Rates       Weights      Rates  × Weights

4.15           0.80           4.15 x 0.80 = 3.32

9.75           0.20          9.75 x 0.20 = 1.95

Hence, The actual rate of the mortgage is,

⇒ 3.32 + 1.95

⇒ 5.27%.

Final answer:

Mikey the monkey ate more bananas than Mick, consuming 5 compared to Mick's 4 bananas.

Explanation:

Let's calculate how many bananas each monkey ate. We'll start with Mick the monkey, who had 10 bananas and ate two fifths of them.

Calculate two fifths of 10 bananas: (2/5) × 10 = 4 bananas.

Mick therefore ate 4 bananas.

Now, let's calculate for Mikey the monkey, who also had 10 bananas and ate half of them.

Calculate half of 10 bananas: (1/2) × 10 = 5 bananas.

Mikey ate 5 bananas.

Mikey the monkey ate more bananas than Mick because 5 is greater than 4.

When number D (which is 92) is divided by 6, the remainder is 2.

Based on the information given, when D is divided by 15, the result is 6 with a remainder of 2, so we can express D as 15*6 + 2 = 92. Now let's find out what happens when D (92) is divided by 6. When we do, we find that 92 divided by 6 gives us 15 with remainder 2. So, the remainder when D is divided by 6 is 2.

Answer:

12/16

Step-by-step explanation:

because he 6 in 4/6 cant go into 16 and 16 from 12/16 c 36 so that is why the answer is 12/16

After simplifying each fraction to its lowest terms, it's clear that 12/16, which simplifies to 3/4, is not equivalent to the others since they all simplify to 2/3.

The question asks which of the following fractions is not equivalent to the others: 24/36, 8/12, 12/16, 4/6. To determine this, we need to simplify these fractions to their lowest terms.

24/36 simplifies to 2/3, by dividing both numerator and denominator by 12.

8/12 simplifies to 2/3, by dividing both numerator and denominator by 4.

12/16 simplifies to 3/4, by dividing both numerator and denominator by 4.

4/6 simplifies to 2/3, by dividing both numerator and denominator by 2.

Therefore, the fraction 12/16 is not equivalent to the others since it simplifies to 3/4, while the others simplify to 2/3.

Answer:

A sphere.

Step-by-step explanation:

The sun is a sphere.

The best geometric shape to describe the Sun is a sphere, as it appears as a circular disc in the sky and fits with observational data and theoretical models of its structure and the Earth's orbit around it.

When considering the geometric shape that best describes the Sun, we assess its physical appearance and symmetry. The Sun is often depicted in diagrams as having a perfectly round, spherical shape, which aligns with our observations, as it appears as a circular disk in the sky. A sphere is a three-dimensional object where every point on the surface is the same distance from the center, which closely matches the Sun's observed shape. Unlike a triangular prism, cube or cylinder, a sphere has no edges, vertices, or faces, which makes it the best match for the Sun's shape.

Moreover, observations about the Sun, like those represented in figures discussing its structure as well as the Earth's orbit around the Sun, support the description of the Sun as being spherical. The orbit of the Earth itself is very close to a circle, which assumes central body - the Sun - of spherical form to exert a uniform gravitational pull. Additionally, the celestial sphere concept, although now known to be an incorrect model for the universe, also envisions stars, including our Sun, as points on a vast imaginary sphere, once more alluding to the spherical structure of these celestial bodies.

Answer:

z = 73

x = 15

Step-by-step explanation:

Since z and (5x +32) share a straight line, adding them would equal 180.

(5x+32) + z = 180

Since z is 73, we can replace z

(5x + 32)  + 73 = 180

(5x + 32) = 107

(5x) = 75

x = 15

Step-by-step explanation:

(8r⁶s³-9r⁵s⁴+3r⁴s⁵)-(2r⁴s⁵-5r³s⁶-4r⁵s⁴)​

We need to combine like terms, take care the exponents of r and s

(8r⁶s³-9r⁵s⁴+3r⁴s⁵)-(2r⁴s⁵-5r³s⁶-4r⁵s⁴)​

multiply the second parenthesis by -1

= 8r⁶s³-9r⁵s⁴+3r⁴s⁵-2r⁴s⁵+5r³s⁶+4r⁵s⁴

= 8r⁶s³ + (-9r⁵s⁴ + 4r⁵s⁴) + (3r⁴s⁵-2r⁴s⁵) + 5r³s⁶

The product in simplest form is (x - 4)

Solution:

Given expression is:

[tex]\frac{8}{2x+8} \times \frac{x^2-16}{4}[/tex]

We have to find the product in simplest form

In the given expression,

2x + 8 = 2(x+ 4)

We know that,

[tex]a^2-b^2=(a+b)(a-b)[/tex]

Therefore,

[tex]x^2-16 = x^2-4^2 =(x+4)(x-4)[/tex]

Substitute these in given expression

[tex]\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4}[/tex]

Cancel the common factors,

[tex]\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4} = x - 4[/tex]

Thus the product in simplest form is (x - 4)

Final answer:

The expression 3a + 3b is not equivalent to 3(a + 2b). The first results in 3a + 3b, while applying the distributive property to the second expression gives 3a + 6b, clearly showing the expressions are different.

Explanation:

The statement 3a + 3b is equivalent to 3(a + 2b) is false. To show this, we can apply the distributive property of multiplication over addition, which states that for any real numbers a, b, and c, a · (b + c) = a·b + a·c. Using this property, we can expand 3(a + 2b) to get 3·a + 3·2b, which simplifies to 3a + 6b. This is not the same as 3a + 3b since 3b is not equal to 6b. Therefore, the expressions are not equivalent.
