A beluga whale is 5 yards and 3 inches long, and a gray whale is 15 yards and 5 inches long. What is the difference in length between the two whales? how many yards and how many inches​

Answer: Yes

Step-by-step explanation: Erica would be correct. 4x is called a term. When we see a variable next to a number which in this case is X, it's important to understand that this means multiplication.

We can also say that the expression 4x is a product of both 4 and X.

Final answer:

Erica is correct; the expression 4x is considered one term because it consists of a single element with a coefficient and a variable multiplied together.

Explanation:

Erica is correct in saying that the expression 4x has one term. In mathematics, a term is a single mathematical expression that may be a number, a variable, or numbers and variables multiplied together. The expression 4x consists of the number 4 and the variable x multiplied together, which forms a single term. It does not have any addition or subtraction signs that would separate it into multiple terms.

Answer:

Pretty sure the answer is 20 :)

Answer:

20 inches

Step-by-step explanation:

From the question, diagonal of the television screen is given to be 25 inch and the  width of the television set is given to be 15 inches and we are asked to find the height of the screen.

We can solve this question using the Pythagoras theorem.

The Pythagoras theorem states that in a right-angle triangle;

opposite²  +  adjacent²  = hypotenuse²

From the question, the width is given to be 15 inches, the with is  our adjacent. Also the diagonal is given to be 25 inches, the diagonal is  our hypotenuse. And we were ask to find the height, the height is our opposite.

so;

opposite = ?  

adjacent = 15

hypotenuse = 25

Let opposite = x

we can now substitute into our theorem;

opposite²  +  adjacent²  = hypotenuse²

x²     +    15²  = 25²

x²   =   25²  -   15²

x²    =  625  -  225

x²   = 400

x    =  √400

x     =  20

opposite  =  20 inches

Since opposite is the height of the screen, then the height of the screen is 20 inches.

Therefore the height of the screen is 20 inches.  

Answer:

A

Step-by-step explanation:

We take the percentage raise and convert to decimal by dividing by 100. Then multiply this with the salary before raise. This will give us the "raise amount".

Then we will add up all of the "raises" of 3 employees to get our answer.

Jane = 4/100 = 0.04

0.04*41,500 = 1660

John = 4.5/100 = 0.045

0.045 * 44,100 = 1984.5

Jack = 3/100 = 0.03

0.03 * 39,600 = 1188

Sum of all 3 raises:

1660 + 1984.5 + 1188 = $4832.5

From the answer choices, A is the closest, $4833

Answer:

B. -x + 8

Step-by-step explanation:

Given expression

[tex]\dfrac{8-4(x-6)}{4}[/tex]

Consider the numerator [tex]8-4(x-6).[/tex]

First, use distributive property:

[tex]8-4(x-6)=8-(4x-24)[/tex]

Open the brackets:

[tex]8-(4x-24)=8-4x+24[/tex]

Combine the like terms:

[tex]8-4x+24=(8+24)-4x=32-4x[/tex]

Again use distributive property:

[tex]32-4x=4\cdot 8-4x=4(8-x)[/tex]

Now, the expression is

[tex]\dfrac{4(8-x)}{4}=8-x\ \text{or}\ -x+8[/tex]

Answer:

900 minutes

Step-by-step explanation:

Plan A: 700 free minutes + 15 cents per minute over 700 ($40)

Plan B: 500 free minutes + 5 cents per minute over 500 ($50)

The charges for x minutes (assumed x>700) for plan A will be

40+0.15(x-700)

The charges for x minutes (assumed x>500) for plan B will be

50+0.05(x-500)

To find the value of x where both charges are the same, we equate

40+0.15(x-700)=50+0.05(x-500)

Operating

40+0.15x-105=50+0.05x-25

Simplifying

0.10x=90

x=900 minutes

Both plans would charge the same amount when 900 minutes per month are used

Answer:

a. 4 represents the amount of pounds of strawberries each friend got.

b. 4 represents the number of friends who were sharing the strawberries.

Step-by-step explanation:

You need to analize the information given in the exercise.

You know that the total amount of pounds of strawberries that are shared equally is:

[tex]Total=20\ lb[/tex]

a. Then if the group of people is formed by 5 friends, you need to divide the total pounds of strawberries that by 5 in order to calculate the amount of pounds of strawberries each one of them got.

If in the equation [tex]20\div5=4[/tex], 5 represents the number of people, then 4 represents the amount of pounds of strawberries each friend got.

b. If each person got 5 pounds of strawberries, you can calculate the number of friends who was sharing them by dividing the total pounds of strawberries by 5.

So, if in the equation [tex]20\div5=4[/tex],  5 represents the pounds of strawberries per person, then 4 represents the number of friends who were sharing the strawberries.

The mathematics problem given, namely 20 divided by 5 equals 4, represents the principle of equally distributing 20 strawberries among 5 friends. Each friend gets 4 strawberries.

The subject of your question is mathematics. The equation 20 divided by 5 equals 4 represents how twenty pounds of strawberries can be equally divided among a group of five friends. This is a division problem, an essential operation in arithmetic.

The principle it is demonstrating is how to distribute something equally among a group. In this case, if we have 20 strawberries and need to distribute them evenly among 5 friends, each friend will receive 4 strawberries. This is represented mathematically as 20 (total strawberries) divided by 5 (number of friends) equals 4 (strawberries per friend). So, your equation is correct.

Answer:

Let l be the length and w the width of the rectangle.

P as the perimeter and A as the area.

length of a rectangle is four times the width:

w = w

l = 4w

System of equation : 2l + 2w = P

Substitute:

2(4w) + 2w = 45

8w + 2w

10w = 45

w = 45 / 10

w = 4.5

Solve for l:

l = 4w

l = 4(4.5)

l = 18

Area:

A = lw

A = 18(4.5)

A = 81 in²

Answer:

area =81  square inches

Step-by-step explanation:

width =w

lenght= 4w

2w + 2(4w)=45

10w=45

w=4.5

l= 4.5(4) = 18

4.5+4.5 +18+18 = 45

Area = l*w

4.5*18 = 81

Area= 81 square inches

Answer:

Co-ordinates of point R is (26,2)

Step-by-step explanation:

Given point:

Endpoint S(8,4)

Mid-point M of segment RS (17,3)

Let endpoint [tex]R[/tex] have co-ordinates [tex](x_2,y_2)[/tex]

Using midpoint formula:

[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are co-ordinates of the endpoint of the segment.

Plugging in values to find the midpoint of segment KN.

[tex]M=(\frac{8+x_2}{2},\frac{4+y_2}{2})[/tex]

We know [tex]M(17,3)[/tex]

So, we have

[tex](17,3)=(\frac{8+x_2}{2},\frac{4+y_2}{2})[/tex]

Solving for [tex]x_2[/tex]  

[tex]\frac{8+x_2}{2}=17[/tex]

Multiplying both sides by 2.

[tex]\frac{8+x_2}{2}\times 2=17\times 2[/tex]

[tex]8+x_2=34[/tex]

Subtracting both sides by 8.

[tex]8+x_2-8=34-8[/tex]

∴ [tex]x_2=26[/tex]

Solving for [tex]y_2[/tex]  

[tex]\frac{4+y_2}{2}=3[/tex]

Multiplying both sides by 2.

[tex]\frac{4+y_2}{2}\times 2=3\times 2[/tex]

[tex]4+y_2=6[/tex]

Subtracting both sides by 4.

[tex]4+y_2-4=6-4[/tex]

∴ [tex]y_2=2[/tex]

Thus co-ordinates of point R is (26,2)  (Answer)

The answer is 148 degrees

Step-by-step explanation:

I'm pretty sure it is 148°... In my notes it says "if a tangent to a circle & a chord intersect at a point on the circle, then the measure of each angle they form is one-half the measure of its intercepted arc." Hope this helps...

Read more on Brainly.com - https://brainly.com/question/3819019#readmore

The measure of arc QPN is 148° if the measure of angle QNT is 74°.

Given a circle with center O.

TS is the tangent of the circle at point N.

From the figure, we have, ∠ONT = 90°, since the angle formed at the tangent by the diameter is always the right angle.

Now,

m∠ONT = m∠QNT + m∠ONQ

Substitute the values.

90° = 74° + m∠ONQ

m∠ONQ = 90 - 74 = 16°

Now, from triangle QNO, OQ = ON, since, both are radii of the same circle.

The angle which lies opposite to these sides will be also equal.

So, m∠ONQ = m∠OQN =  16°.

Now, by the angle sum property of a triangle, the sum of the interior angles of a triangle is 180°.

So,

m∠ONQ + m∠OQN + m∠QON = 180°

16° + 16° + m∠QON = 180°

m∠QON = 180° - (16° + 16°)

m∠QON = 148°

The measure of arc QPN is equal to the central angle = 148°

Answer:

For 2.5 x - 1.75 = 5 (7 - 0 5 x) ,   x  = 1.47/1.1

Step-by-step explanation:

Here, the given equation is :  2.5 x - 1.75 = 5 (7 - 0 5x)

By DISTRIBUTIVE PROPERTY:

A(B -  C) =  AB - AC

Solving for the value of x , we get:

2.5 x - 1.75 = 5 (7 - 0 5 x)

⇒ 2.5 x - 1.75 = 5 (7)  - 5 (05 x)

⇒ 2. 5 x - 1. 75 = 35 - 25 x

or, 2. 5 x + 25 x = 35 + 1. 75

or, 27 . 5 x = 36.75

⇒ x =  36.75/ 27.5  =  7.35/ 5.5 = 1.47/1.1

or, x  = 1.47/1.1

Hence, for 2.5 x - 1.75 = 5 (7 - 0 5 x) ,   x  = 1.47/1.1

Total number of Jelly beans in the sack = 72

Number of red beans = 36

Number of green beans = 12

Number of yellow beans = 12

Number of orange beans = 6

Number of black beans = 6

Step-by-step explanation:

Let total number of jelly beans be =[tex]x[/tex]

We are given fractions of different colors of beans. To find the exact number of beans we need to multiply the fraction with the total number of beans.

Fraction of total are red beans = [tex]\frac{1}{2}[/tex]

Number of red beans = [tex]\frac{1}{2}\times x= \frac{x}{2}[/tex]

Fraction of total are green beans = [tex]\frac{1}{6}[/tex]

Number of green beans = [tex]\frac{1}{6}\times x= \frac{x}{6}[/tex]

Fraction of total are yellow beans = [tex]\frac{1}{6}[/tex]

Number of yellow beans = [tex]\frac{1}{6}\times x= \frac{x}{6}[/tex]

Fraction of total are orange beans = [tex]\frac{1}{12}[/tex]

Number of orange beans = [tex]\frac{1}{12}\times x= \frac{x}{12}[/tex]

Number of black beans = 6

Total number of beans can be given as

[tex] \frac{x}{2}+\frac{x}{6}+\frac{x}{6}+\frac{x}{12}+6[/tex]

Since we assumed total number of beans to be [tex]x[/tex], so we have.

[tex] \frac{x}{2}+\frac{x}{6}+\frac{x}{6}+\frac{x}{12}+6=x[/tex]

Multiplying each term by 12 to remove fractions.

[tex] (12\times\frac{x}{2})+(12\times\frac{x}{6})+(12\times\frac{x}{6})+(12\times\frac{x}{12})+(12\times6)=12\times x[/tex]

[tex]6x+2x+2x+x+72=12x[/tex]

combining like terms.

[tex]11x+72=12x[/tex]

Subtracting both sides by [tex]11x[/tex]

[tex]11x+72-11x=12x=11x[/tex]

[tex]72=x[/tex]

∴ [tex]x=72[/tex]

Total number of Jelly beans in the sack = 72

Number of red beans = [tex]\frac{1}{2}\times 72= 36[/tex]

Number of green beans = [tex]\frac{1}{6}\times 72= 12[/tex]

Number of yellow beans = [tex]\frac{1}{6}\times 72= 12[/tex]

Number of orange beans = [tex]\frac{1}{12}\times 72= 6[/tex]

number of black beans = 6

Justin has 72 jelly beans in total. By dividing the total number accordingly, he has 36 red, 12 green, 12 yellow, 6 orange, and 6 black jelly beans.

Let's assume the total number of jelly beans Justin has is represented by the variable x. We know that half of them are red, so there are x/2 red jelly beans. Similarly, since 1/6 are green and another 1/6 are yellow, there are x/6 green jelly beans and x/6 yellow jelly beans. As for the orange jelly beans, they represent 1/12 of the total, which means Justin has x/12 orange jelly beans. We are given that there are 6 black jelly beans, which do not need to be divided into fractions. To find the total, x, we can write an equation considering all the portions mentioned and the known number of black jelly beans:

x/2 (red) + x/6 (green) + x/6 (yellow) + x/12 (orange) + 6 (black) = x

Finding a common denominator (12), we rewrite the equation:

6x/12 + 2x/12 + 2x/12 + x/12 + 6 = x

Combine like terms:

(6x + 2x + 2x + x)/12 + 6 = x

11x/12 + 6 = x

To solve for x, subtract 11x/12 from both sides:

6 = x - 11x/12

6 = x(12/12) - 11x/12

6 = (12x - 11x)/12

6 = x/12

Multiplying both sides by 12 gives us:

x = 72

So, Justin has a total of 72 jelly beans. Calculating the number for each color:

In conclusion, Justin has 36 red, 12 green, 12 yellow, 6 orange, and 6 black jelly beans, adding up to a total of 72 jelly beans.

To fit two identical cars in a 23-foot 6-inch wide garage with 3 feet 6 inches clearance on each side and between the cars, the cars must each be 6 feet 6 inches wide.

The subject matter of your question is a math problem involving subtraction and division. To find out how wide the cars can be, you first need to determine the total available space for the cars. The total width of the garage is 23 feet 6 inches. However, you need to leave room for clearance on either side of the cars and in between them. The clearance is a total of 3 feet 6 inches multiplied by 3 (one for each side and one for between the cars), which is 10 feet 6 inches. Subtract this from the total width of the garage, and you get 13 feet available for the cars. Since the cars are identical, you simply divide this by 2. Each car can be 6 feet 6 inches wide.
