What is the weight (in grams) of a liquid that exactly fills a 182.8 milliliter container if the density of the liquid is 0.135 grams over milliliter? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.

Answers

The weight in grams of the liquid in the container is required.

The weight in grams of the liquid that fills the container is 24.68 grams. The calculations to find this value is shown below.

Density

V = Volume of liquid in the container = 182.8 milliliter

[tex]\rho[/tex] = Density of liquid = 0.135 grams over milliliter

The relation between volume, mass and density is given by

[tex]m=\rho V\\\Rightarrow m=0.135\times 182.8\\\Rightarrow m=24.678\approx 24.68\ \text{grams}[/tex]

Which expression’s product is modeled by the tiles? A. (x + 1)(x + 3) B. x(x + 3) C. 3(x + 1) D. (3x + 1)(x + 1)

Answers

The product of the expression modeled by the tiles is likely to be (x + 1)(x + 3).

What is expression?

An expression in mathematics is a combination of numbers, variables, and operators that represent a value or a relationship between values. Expressions can be simple or complex, and they can be used to perform mathematical operations or to represent mathematical concepts. For example, the expression 2 + 3 is a simple expression that represents the sum of 2 and 3. The expression x + y is a more complex expression that contains variables, which can take on different values. The expression (x + y)² represents the square of the sum of x and y. In general, an expression can be evaluated to find its value. For example, if we assign the value of 3 to x and the value of 4 to y, then the expression (x + y)²  can be evaluated as (3 + 4)^2 = 7² = 49. Expressions play a fundamental role in mathematics, and they are used in a wide range of mathematical concepts, including algebra, calculus, and geometry.

Here,

This can be deduced from the fact that two tiles with the same x term are placed next to each other and the other two tiles have a constant term.

The product of these two tiles would then be expression (x + 1)(x + 3).

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)​

Answers

Answer:

47378.31625 Liters

Step-by-step explanation:

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)

From the above question,

1 gallon = 3.79 Liters

12500 7/8 gallons = x Liters

Cross Multiply

x Liters = 12500 7/8 × 3.79 Liters

x = 47378.31625 Liters

Therefore, the number of liters of water in the fountain is 47378.31625 Liters

is -6/3 and integer? dont guess ;( helppp

Answers

Answer:

no because

Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

-6/3 is not an integer.

What is Number system?

A number system is defined as a system of writing to express numbers.

We need to check whether -6/3 is a integer or not .

An integer is a whole number (not a fractional number) that can be positive, negative, or zero.

The given number is a fraction which is not comes under the integers.

All whole numbers are integers but  but not all integers are whole numbers or natural numbers.

If the fraction is simplified we get -2 which will be an integer but the fraction form is not considered as integer.

Hence, -6/3 is not an integer.

Solve for x. Enter the solutions from least to greatest. Round to two decimal places. (x-6)^2-5=0 lesser x= , greater x=​

Answers

Answer: lesser x = 3.76 & greater x = 8.24

Step-by-step explanation: just took the test

For the given quadratic equation lesser x=3.765 and greater x=8.235.

The given quadratic equation is (x-6)²-5=0.

We need to find the solutions from least to greatest.

What is the formula to find the solution to the quadratic equation?

The formula to find the solution to the quadratic equation is [tex]x=\frac{-b\pm\sqrt{b^{2}-4ac }}{2a}[/tex].

Now, (x-6)²-5=0 can be written as x²-12x+31=0

Here, a=1, b=-12 and c=31

x=(12±√20)/2

⇒x=(12±4.47)/2

⇒x=3.765 or x=8.235

Therefore, lesser x=3.765 and greater x=8.235.

Find the value of x.
A 2

D 6.4

Answers

Answer:

D

Step-by-step explanation:

Δ DCA and Δ ABE are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{CA}{BE}[/tex] = [tex]\frac{DA}{AE}[/tex] , substitute values

[tex]\frac{18}{10}[/tex] = [tex]\frac{x+8}{8}[/tex] ( cross- multiply )

10(x + 8) = 144 ( divide both sides by 10 )

x + 8 = 14.4 ( subtract 8 from both sides )

x = 6.4 → D

The value of x is the length of BD, so x = 6.So, The correct answer is C. 6.

The value of x is the length of the altitude from vertex B to side AC. We can find this length by using the Pythagorean Theorem on right triangle ABD.

[tex]AB^2 + BD^2 = AD^2\\8^2 + BD^2 = 10^2\\BD^2 = 36\\BD = 6[/tex]

The altitude from vertex B to side AC is equal to the length of BD, so x = 6.

Here is a breakdown of the steps involved in solving for x:

We are given the lengths of sides AB and AC of triangle ABC.

We know that the altitude from vertex B to side AC will be perpendicular to side AC. We can use the Pythagorean Theorem on right triangle ABD to find the length of BD, which is the altitude from vertex B to side AC.

2x+y=13;5x−4y=13

Step 1: Solve 2x+y=13 for y:

Solve 2x + y = 13 for y

2x + y + -2x = 13 + -2x

(add -2x to both sides)

y = -2x + 13

Step 2: Substitute −2x+13 for y in 5x−4y=13:

5x−4y=13

5x−4(−2x+13)=13

13x−52=13(Simplify both sides of the equation)

13x−52+52=13+52(Add 52 to both sides)

13x=65

(Divide both sides by 13)

13x/13 = 65/13

x = 5

Step 3: Substitute 5 for x in y = −2x+13:

y = −2x+13

y = (−2)(5)+13

(Simplify both sides of the equation)

y = 3

Answer: x= 5, y= 3
