PLS HELP Find The Value Of X.A. 7B. 14C. 3D. 11

Answers

Answer 1

Answer:

A

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

21 - x = [tex]\frac{1}{2}[/tex] (17 + 11)

21 -x = [tex]\frac{1}{2}[/tex] × 28 = 14 ( subtract 21 from both sides )

- x = - 7 ( multiply both sides by - 1 )

x = 7 → A

Answer 2

The value of x is 7

What is mid  point theorem?

The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the length of the third side. This theorem is used in various places in real life, for example in the absence of a measuring instrument, we can use the midpoint theorem to cut a stick into half.

Midpoint Theorem Formula

In math, we also have a midpoint theorem formula which has its applications in coordinate geometry. It can also be known as the midpoint theorem of a line segment. It states that if we have a line segment whose endpoints coordinates are given as (x1, y1) and (x2, y2), then we can find the coordinates of the midpoint of the line segment by using the formula given below:

Let (xm, ym) be the coordinates of the midpoint of the line segment. Then,

(xm, ym) = ( (x1 + x2)/2 , (y1 + y2)/2 )

This is known as the midpoint theorem formula.

As, midsegment is half the sum of the parallel bases

21 - x = 1/2 (17 + 11)

21 - x= 12* 28

21-x= 14

x= 7

A man received a monthly salary of $3500 together with a commission of 5% on all sales over $5000 per month. Calculate his gross salary in a month in which his sales amounted to $40,000.

Answers

Answer:

$5500

Step-by-step explanation:

3500 + 0.05 * 40,000 = 5500

His gross salary in a month in which his sales amounted to $40,000 would be; 5500 dollars.

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

It is given that man received a monthly salary of $3500 together with a commission of 5% on all sales over $5000 per month.

Let the x represents his gross salary in a month in which his sales amounted to $40,000.

Therefore,

x = 3500 + 0.05 (40,000)

x = 3500 + 2000

x = 5500

Hence,  his gross salary in a month in which his sales amounted to $40,000 would be; 5500 dollars.

En el numeral 87.684 la cifra de las decimas es la cifra de las centésimas es la cifra de las milésimas es la parte entera de la expresión decimas es en la parte entera, la cifra de unidades es , mientras que la cifra de la decena es

Answers

Answer:

La cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.

Step-by-step explanation:

Para responder la pregunta, se debe descomponer el número en cuestión:

87.684

8 = Indica la cantidad de decenas del número, es decir, 8 decenas (80).

7 = Indica las unidades dentro de la decena, es decir, 7 unidades más que 80.

.6 = Indica la cantidad de decenas del entero.

.08 = Indica la cantidad de centésimas del entero.

.004 = Indica la cantidad de milésimas del entero.

Así, la cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.

An oil-drilling rig has dug a hole to a depth of -60 ft. after one full day and night of continuous
use. The rate of the rig stayed constant over that time.
Part A: The rig will be used to dig a second hole with a depth of -150 ft at the same rate as
before. How many hours will the rig take to complete digging the hole?

Answers

Answer:

It will take 60 hrs

Hope this helped!

Answer:

It would take 60 hours for the rig to complete digging the -150 ft. hole.

Step-by-step explanation:

Hint: Using ratios will help solve questions like this one.

The first hole was dug -60 ft. below the surface for a whole day and night. A day lasts 12 hours and the same goes for a whole night. That's 24 hours in total. This will help answer Part A. A second hole was dug -150 ft. below the surface with the same rate as the first hole. Let's put this into a ratio.

-60 : 24

-150 : ?

Finding the scale factor in ratios will help solve for the missing value. We can divide -150 by -60 which results in 2.5. Multiply 2.5 by 24 and you will get 60 hours as your final answer. I hope you will find this helpful! :D

Answer:

Step-by-step explanation:

Answer:

A1. The answer is option (b) 1/10

A2. The answer is option (b) 13.4 cm²

A3. Shaded area not provided

A4. The answer is option (b) Unlike Fractions

A5. The answer is option (d) 20

A6. The answer is option (b) 21/23

A7. The answer is option (c) 5/27

Step-by-step explanation:

A1. We multiply the denominators (the numbers on the bottom) and the numerators (the numbers on top) to multiple fractions. As a result, for (1/2) x (1/5), we have

(1/2) × (1/5) = (1 × 1) / (2 × 5) = 1/10.

A2. Multiplying the length by the breadth yields the area of a rectangle. The dimensions in this instance are 6.7 cm in length and 2 cm in width. So, the area may be determined as follows:

Area = length × breadth = 6.7 cm × 2 cm = 13.4 cm².

Hence, the correct answer is (b) 13.4 cm².

A3. Please provide the shaded  area.

A4. Fractions that have different denominator are called unlike fractions.

So the answer is option (b)

A5.Let us suppose India played  'x'  number of matches

According to the Question, India won 3/5 of its matches, which implies that they won 3/5  * x matches.

It is also mentioned that India won 4 more matches than it lost against New Zealand. Therefore, the number of matches India won against New Zealand is 4 more than the number of matches it lost against New Zealand.

From this, we can set up the equation:

3/5 * x = (x/2) + 4

Multiplying both the sides by 10, we have

6x = 5x + 20

subtracting 5x from both sides:

6x - 5x = 5x - 5x + 20

x = 20

Hence, India played 20 matches.

A6. When the numerator is less than the denominator, the fraction is said to be proper fraction. Hence among the given options, 21/23 fits the best.

Hence option (b) is correct

A7. To find what should be added to 21/27 to make it 26/27, we need to calculate the difference between the two fractions.

Let  us suppose that we need to add x

=> 21/27 + x = 26/27

=> x= 26/27 - 21/27 = 5/27

Therefore, the answer is (c) 5/27.

picking a tile that is the letter Y as a fraction and as a percent. From which bag are you more likely

to pick a tile that is the letter Y?

The probability of picking the letter Y from bag of 50 letters is 23/50 or 0.46 or 46% and probability of picking the letter Y form bag of 200 letters is 172/200 or 0.86 or 86%. as the probability of getting the letter Y is more in second bag this it is better to pick the bag containing 200 letters.

What is a probability?

The probability explains the chances of happening a event. The probability of an event is a number between 0 and 1, where, 0 indicates impossibility of the event to happen and 1 indicates certainty of the event to happen.

From the question it is said that a bag of 50 letter contain 23 Y letters. Thus the probability of the letter Y picking is 23/50 i.e, number of times the letter Y can come out if we pick the letters 50  times. So, it is certain that 23 Y letters can come out.

23/50= 0.46 or 46%

And if the bag contain 200 letters in which 172 are Y letters then the probability to pick Y is 172/200

172/100 =0.86 or 86%

As the chance to get Y letter is mor in bag containing 200 letters thus pick this bag.

thus the 1st bag probability is 46% and for 2nd bag is 86%. Hence choose 2nd bag

Basically, it has to be carried out on the customers themselves. By costumers, we mean those that have bought and/or used the service or product.

For the local appliance store, the manager should survey people that have bought at least one major appliance from the store. Those are the right people that should make up the population to be surveyed. This is because;

i. They are the consumers of the product.

ii. They have bought and definitely used the product.
