The expression 8x + 4y is not equivalent to 4(2x + 1). Therefore, 8x + 4y = 4(2x + y)

Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them.

Equivalent expressions are expressions that have similar value or worth but do not look the same.

Let's determine whether the expression 8x + 4y is equivalent to 4(2x + 1).

Let's factorise to know whether the expressions are equivalent.

Therefore, using the common factors,

8x + 4y = 4(2x + y)

Hence, the expression are not equivalent .

Answer:

The correct answer is b.

Answer:

Step-by-step explanation:

The two base angles in each triangle are equal. (The triangle is isoceles and the property used is angles opposite equal sides are equal).

Now the tricky part. The peak angles are also equal. That's because both peak angles are made equal by Peak angle + 2*base angle = 180

Peak angle = 180 - 2*base angle

Therefore the triangles are congruent by SAS.  

I suppose you could get them equal by taking one of the base angles (all 4 are equal to each other) and the peak angles and claim equality by ASA, but it seems a little bit tortuous to me.

Answer:20

Step-by-step explanation:

The probability that the number is 6 and the letter is a consonant is 3/40.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

The probability of choosing the number 6 is 1/10, since there are 10 possible digits to choose from (0 to 9) and each is equally likely to be chosen.

The probability of choosing a consonant from the alphabet depends on the definition of "consonant". If we define consonants as all the letters in the alphabet except for A, E, I, O, and U (i.e., the vowels), then there are 21 consonants in the alphabet.

The total number of letters in the alphabet is 26, so the probability of choosing a consonant is 21/26

To find the probability that the number is 6 and the letter is a consonant, we need to multiply the probabilities of these events occurring independently:

P(number is 6 and letter is a consonant) = P(number is 6) * P(letter is a consonant)

= (1/10) * (21/26)

= 21/260

= 3/40

Therefore, the probability that the number is 6 and the letter is a consonant is 3/40.

Step-by-step explanation:

The measure of the inscribed angle G in the circle is 85 degree.

An inscribed angle is simply an angle with its vertex on the circle and whose sides are chords.

The relationhip between an an inscribed angle and intercepted arc is expressed as:

Inscribed angle = 1/2 × intercepted arc.

Since the circle equals 360 degrees, we can determine the intercepted arc DF.

Hence:

Arc DF = 360 - ( 70 + 120 )

Arc DF = 360 - 190

Arc DF = 170°

Now, plug the value into the above formula:

Inscribed angle = 1/2 × intercepted arc.

Inscribed angle G = 1/2 × 170°

Inscribed angle G = 85°

Therefore, angle G has a measure of 85 degree.

Answer:

  1/60 gallon

Step-by-step explanation:

You want to know what is left of 4/5 gallon of paint if 3/4 gallon was used to paint a doghouse, and 2/3 of the remaining amount was used to paint a door.

To find the amount remaining we subtract the amount used for the doghouse from the original amount:

  4/5 -3/4 = (16 -15)/20 = 1/20 . . . . . gallon

2/3 of that was used, so 1/3 of it remains:

  (1/3)(1/20 gallon) = 1/60 gallon

There is 1/60 of a gallon of paint left in the can.

The length AC in the kite is 8.7 cm.

A kite is a quadrilateral that has two pairs of consecutive equal sides and

perpendicular diagonals. Therefore, let's find the length AC in the kite.

Hence, using Pythagoras's theorem, let's find CE.

Therefore,

7² - 4² = CE²

CE = √49 - 16

CE = √33

CE = √33

Let's find AE as follows:

5²- 4² = AE²

AE = √25 - 16

AE = √9

AE = 3 units

Therefore,

AC = √33 + 3

AC = 5.74456264654 + 3

AC = 8.74456264654

AC = 8.7 units

After solving the equations, we know that a total of 25 ladies attended the party.

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.

As in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, and others.

So, take dudes as x and ladies as y.

Now, form the required 2 equations as follows:
2x + y = 45 ...(1)

x + y = 35 ...(2)

Work on equation (2):

x + y = 35

x = 35 - y

Now, substitute x = 35 - y in equation (1):

2x + y = 45

2(35-y) + y = 45

70 - 2y + y = 45

-y = -25

y = 25

Answer: $8,849

Step-by-step explanation: 17,698 divided by two people is 8,849, therefore each sister paid $8,849.

Answer: $8849

Step-by-step explanation: We are given that the total amount both sisters pay is $17698. They each pay for a fraction though. That fraction is 1/2 since they each pay for half. We multiply this fraction by the total which is 17698 to find our answer.

If there were three sisters and they each paid one-third, we would multiply the total price by 1/3 to find our answer.

To horizontally compress a function by a factor of 5, we replace x by 5x in the function. Therefore, the new function is: g(x) = √(5x).

A function is a mathematical object that takes one or more input values (called the domain) and produces a corresponding output value (called the range). In other words, it is a rule that assigns each input a unique output. Functions are commonly represented using algebraic expressions or equations, graphs, tables, or verbal descriptions. They are widely used in mathematics, science, engineering, and many other fields to model and analyze relationships between variables, predict outcomes, and solve problems.

Here,

(a) Reflection about the x-axis:

To reflect a function about the x-axis, we multiply it by -1. Therefore, the new function is: g(x) = -√x.

(b) Reflection about the y-axis:

To reflect a function about the y-axis, we replace x by -x in the function. Therefore, the new function is: g(x) = √(-x).

(c) Horizontal stretch of 5:

To horizontally stretch a function by a factor of 5, we replace x by x/5 in the function. Therefore, the new function is: g(x) = √(x/5).

(d) Horizontal compression of 5:

To horizontally compress a function by a factor of 5, we replace x by 5x in the function. Therefore, the new function is: g(x) = √(5x).

(b) Bread: A/4 slices, Beans: B/21 - (A/4) * (12/21) servings.

(a) To prepare a meal of "beans-on-toast" that supplies 20 grams of protein and 80 grams of carbohydrates, you can use the following combination:

- Servings of Campbell's Pork & Beans: 4 servings.

- Slices of "lite" rye bread: 15 slices.

By using 4 servings of Campbell's Pork & Beans, you will obtain a total of 20 grams of protein (5 grams per serving) and 84 grams of carbohydrates (21 grams per serving).

Combining this with 15 slices of "lite" rye bread will contribute an additional 60 grams of carbohydrates (12 grams per slice) and 4 grams of protein (4 grams per slice). Thus, your meal will meet the desired nutritional requirements of 20 grams of protein and 80 grams of carbohydrates.

(b) The formula to determine the number of slices of bread and servings of Pork & Beans needed to meet specific protein and carbohydrate requirements is as follows:

- Number of slices of bread (Bread): A divided by 4.

- Number of servings of Pork & Beans (Beans): (B divided by 21) minus ((A divided by 4) multiplied by (12 divided by 21)).

Using this formula, you can calculate the appropriate quantities of bread and beans based on the desired protein (A) and carbohydrate (B) values.

The alternative hypothesis (Ha) is that the proportion of alumni and supporters who provide monetary contributions is less than 13%.

A statistical hypothesis is usually formulated to test whether there is a significant difference or relationship between two or more variables.

There are two types of statistical hypotheses:

Null hypotheses, which assume that there is no significant difference or relationship between variables

Alternative hypotheses: these assume that there is a significant difference or relationship between variables.

We have,

From the situation given we can create the null and the alternative hypothesis as,

The null hypothesis (H0) is that the proportion of alumni and supporters who provide monetary contributions is equal to or greater than 13%.

i.e

(p ≥ 0.13).

The alternative hypothesis (Ha) is that the proportion of alumni and supporters who provide monetary contributions is less than 13%.

i.e

(p < 0.13)

Now,

Mathematically,

H0: p ≥ 0.13

Ha: p < 0.13

Where p represents the true proportion of alumni and supporters who provide monetary contributions.
