Can someone please help me with this.

An equation is shown below:

6(2x - 11) + 15 = 21

Write the steps you will use to solve the equation and explain each step.

 Respuesta:98%

Explicación pasto a paso: Sumaremos la cantidad indicada con el 100%. Por ejemplo: 10%+100%= 110%

Entonces:

110/100 × 120/100 × 150%= 198%

Luego restamos: 198% - 100%= 98% Respuesta: Aumento único= 98%

Answer:

$8.88

Step-by-step explanation:

24yds needed = 864 inches

864/150 = 5.76 so he'll need 6 spools

6x 1.48 = $8.88

Answer:

$7.40

Step-by-step explanation:

First, take 78% of 24, which is 18.72. So 18.72 yards of ribbon will be blue. Then, convert the number of yards to inches. You can multiply it by 3 to get the number of feet and then that number by 12 to get the number of inches. So you'll have 673.92. Next, figure out how many spools Jordan needs. Divide 673.92 by 150. You get around 4.4, but since you can't buy 0.4 spools, Jordan will need to buy 5 of them.

So multiply 1.48 dollars by 5 spools and you'll get $7.40. Which is how much Jordan spent on blue ribbon.

Answer:

93

Step-by-step explanation:

The forecast high is the highest temperature expected to occur that day, which in most cases is in the afternoon. When referring to the recorded high/low from a previous day, the high and low-temperature values are the actual temperature extremes that were recorded during that 24-hour calendar day.

Given: Texas is 92 degrees. January's record low temperature is -1 degrees.

To find:  What is the difference between the record high and low-temperatures?

Solution: Subtract -1 from 92, 92 - (-1) = 93

Answer:

D. 3

Step-by-step explanation:

I mathed it

Answer:

To determine the ratio of the frequency of G to C, we divide the frequency of G by the frequency of C:

G/C = 392/262

Simplifying the ratio by dividing both numbers by 2, we get:

G/C = 196/131

This is an approximate ratio, since we rounded the frequencies to the nearest whole number.

To find out how many G waves will fit in the length of four C waves, we need to compare the wavelengths of the two notes. The wavelength is the distance between two corresponding points on a wave, such as the distance between two peaks or two troughs.

The wavelength is inversely proportional to the frequency, so we can use the ratio of frequencies we found above to determine the ratio of wavelengths:

λ(G)/λ(C) = f(C)/f(G) = 262/392 = 0.668

This means that the wavelength of G is about 0.668 times the wavelength of C. Since the frequency of G is higher than the frequency of C, we can also say that G has more waves per second than C.

To find out how many G waves fit in the length of four C waves, we need to multiply the wavelength of G by the number of waves in four C wavelengths:

4λ(C)/λ(G) = 4/(λ(G)/λ(C)) = 4/0.668 ≈ 5.988

So, approximately 6 G waves fit in the length of four C waves.

Therefore, the answer is (A) 6

Answer:

They will blow together again at 6:00 am

Step-by-step explanation:

Guard 1 whistles every 50 minutes.

Guard 2 whistles every 60 minutes.

Guard 1 whistles every 100 minutes.

Assuming that at the beginning they whistle together, the next time that they will whistle together is after the smallest common multiple of 50, 60, and 100.

Because one of the numbers is 100, it only has multiples like:

100*2 = 200

100*3 = 300

100*4 = 400

etc...

So we need to find a common multiple of 50 and 60 that is also a multiple of 100.

For example, the multiples of 50 that are also multiples of 100 are:

50*2 = 100

50*4 = 200

50*6 = 300

And the multiples of 60 that are also multiples of 100 are:

60*5 = 300

(this is the only one)

Then we can see that a common multiple of 50, 60 and 100 is 300.

Then they will whistle together 300 minutes after the first common whistle.

We know that they blow together at 1:00 am

300 minutes after it is:

First, we need to write 300 minutes in hours.

We know that one hour has 60 minutes.

then 300 minutes = (300 minutes/60 minutes) hours = 5 hours.

300 minutes after 1:00 am is the same as 5 hours after 1:00 am

And 5 hours after 1:00 am is 6:00 am

They will blow together again at 6:00 am

Answer:

16.   Angle 2 is 30° and angles 1 & 3 are 150°

17. Equilateral (all sides are equal)

18. A, B, D

19. A, B. (8 angles and all sides are congruent)

20. False.

Step-by-step explanation:

angle 2 is a corresponding (ish) angle to the one marked 30°, so they are the same. and then the other angle is supplementary to the 30° one, therefore they must add up to 180 degrees. 180-30= 150 so that is angle 1 and 3.

Answer:

question 1 - angle 1 and 2 the answer is 150 and angle 3 is 30

question 2 - the triangle is an equilateral

Answer:

what's the question?............

Answer:

2855.0

Step-by-step explanation:

there are several surface areas.

1. outside surface of the cylinder = circle circumference times height = 2*pi*r*height = 2*pi*14*14 = 1231.5

2. top and bottom of the cylinder = circle area times 2 = pi*r^2 * 2 = pi*14^2 *2 = also 1231.5

3. subtract the 2 cut out rectangles on the top and the bottom = 2* 6*14 = 168

4. add the areas of the inside walls of the cut out block.

there are 2 narrow rectangles = 2* 6*14 = 168

there are 2 squares = 2* 14*14 = 392

so, 1.+2.-3.+4. = 2855.0 (2855.00864...)

Answer:

100°

Step-by-step explanation:

Given

Quadrilateral PQMN and Quadrilateral WXYZ are similar so the corresponding angles are also similar.

so

< Z = <N = 100°

Hope it will help :)❤

Answer:

100 degrees

Step-by-step explanation:

Since quadrilateral PQMN is similar to quadrilateral WXYZ, the corresponding angles must match. That is, [tex]\angle P \cong \angle W[/tex], [tex]\angle Q \cong \angle X[/tex], [tex]\angle M \cong \angle Y[/tex], and [tex]\angle N \cong \angle Z[/tex]. Specifically, [tex]m\angle Z = m\angle N = 100^\text{o}[/tex].

Answer:

X° + 44° = 2x° + 11° [ Sum of two adjacent interior angles of a triangle = opposite exterior angle]

=> - x° = 11°-44°

=> -x° = -33°

=> x° = 33°

Therefore the value of x° = 33°

-2 is rational

This is because every negative integer is a negative rational number.

We know that -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….

In other words, any negative integer n can be written as n = n/1, here n is negative and 1 is positive.

So, negative 2 is rational.
