Answer: The numbers are 13 and 14

Step-by-step explanation:

Since they are two consecutive numbers, let the numbers be x and x+1.

We are told that twice the first number is twelve more than the second number. This can be expressed as:

2 × x = x+1+12

2x = x+13

2x-x = 13

x = 13

Since x = 13, x+1 = 13+1 = 14

The numbers are 13 and 14

Answer:

I=72.9

Step-by-step explanation:

I=PRT When P= the principal=810, R=rate=3% and T=time(by year)=3 years

I=810*3/100*3

I=24.3*3

I=72.9

Answer:

Simple interest/Interest = £72.9

Step-by-step explanation:

We have to find the simple interest at this point.

So use the formula:

I = prt or I = p x r x t

I = amount of interest

P = principal amount (810)

R = interest rate (in years) (.03)

T = amount of time in (years) (3)

All we need to do is multiply.

I = (810)(.03)(3)

I = £72.9

Answer: The question is incomplete

Step-by-step explanation: The answer to this question cannot be determined correctly since an important detail is missing.

However, let me explain how you would normally go about it by using an example of mine. If for example the ratio of yes votes to no votes was 8 to 5, and the question requires you to calculate how many yes votes were there as indicated in your question, then the first step would be to find the total number of both sides of the ratio. That is add 8 to 5 which gives you 13. This means if there was a total of 13 votes cast, every yes vote stands for 8 out of 13 votes and every no vote stands for 5 out of 13 votes.

To express it mathematically, every yes vote would be 8/13 of the total (12779) and every no vote would be 5/13 of the total (12779).

Therefore to determine how many yes votes there was, is calculated as follows;

Let yes votes be y and no votes be x'

y = (8/13) * 12779

y = 102232/13

y = 7864

Based on my example that the ratio of yes votes to no votes is 8 to 5,

Then the number of yes votes was 7,864.

Answer:

Answer:

per second or minute or hour?

per second: 2 per second

per minute: 120 per minute

per hour: 7200 per hour

Step-by-step explanation:

two 1/2 seconds per second so 2 products per second. multiply by 60 for per minute is 120. multiply the minute amount by 60 for hour amount aka 7200.

hope this helps! pls mark brainliest! have a good day!

Answer: She scan products at

Given that: A grocery store clerk can scan one product every 1/2 of a second.

That means:

Rate = 2 per second.

Rate = (2*60) = 120 per minute.

Rate = (120*60) = 7200 per hour

[tex]z<2[/tex]

Step-by-step explanation:

Given the inequality: [tex]-2(z + 5) + 20 > 6[/tex]

Step 1: Distribute the bracket

[tex]-2(z + 5) + 20 > 6\\-2z-10+20>6\\-2z+10>6[/tex]

Step 2: Subtract 10 from both sides

[tex]-2z+10-10>6-10\\-2z>-4[/tex]

Step 3: Divide both sides by -2

Note that when you divide an inequality by a negative sign, the inequality sign is reversed.

[tex]-2z>-4\\\dfrac{-2z}{-2}< \dfrac{-4}{-2}\\\\$Therefore, $z<2[/tex]

Answer:

I think the answer is (x + 4) • (x + 2)

Step-by-step explanation:

First multiply the coefficient of the first term by the constant

Step 2: Find two factors of 8 whose sum equals the coefficient of the middle term 6

Step 3: write the polynomial splitting the middle term using the two factors found in step 2

Step 4:  Add up the first 2 terms, pulling out like factors :

                   x • (x+2)

Add up the last 2 terms, pulling out common factors :

                   4 • (x+2)

Step 5: Add up the four terms in step 4

(x+4)  •  (x+2)

Your final answer is (x + 4) • (x + 2)

Answer:

6.76 in

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.  

Sin α = opposite side / hypotenuse  

Where α is the angle  formed at the intersection between the adjacent side and the hypotenuse , and the opposite side is x :

Replacing with the values given:  

Sin 25 = x/ 16  

Solving for x  

sin25 (16) =x  

x= 6.76 in

Step-by-step explanation:

Given: Perimeter of base of a pyramid = 12.8 m

Height of the pyramid = 12.5 m

To find: volume of a pyramid

Solution:

Perimeter of base of a pyramid = 12.8 m

As base of the pyramid is a square,

12.8 = [tex]4(side\,\,of\,\,a\,\,square)[/tex]

side of a square = [tex]\frac{12.8}{4}=3.2\,\,m[/tex]

Area of a square (A) = [tex](side\,\,of\,\,a\,\,square)^2=(3.2)^2=10.24\,\,m^2[/tex]

Height of the pyramid (h) = 12.5 m

Volume of the pyramid = [tex]\frac{Ah}{3}=\frac{1}{3}(10.24)(12.5)=42.7\,\,cubic \,\,meters[/tex]

4. take 3 from 14 to get 11

Answer:

Option D

Step-by-step explanation:

According to the image description provided:

Term one starts with one dot. One is an odd number.

If you add two to an odd number, the sum would be another odd number. This is what's happening with the pattern.

For example:

[tex]3+2 =5[/tex]

Three is an odd number. If you add two to it, you would get five, which is another odd number.

Term two has 3 dots, term three has 5 dots, term four has 7 dots.

So, all terms should be odd.

Option D should be the correct answer.
