Answer 1

Answer:

3

Step-by-step explanation:

So you have to take the equation, (2a - 7) ÷ b, and you must plug in the numbers for the variables.

(2a - 7) ÷ b

(2(8) - 7) ÷ 3

(16 - 7) ÷ 3

(9) ÷ 3

= 3

Answer:

2051920

Step-by-step explanation:

Alright look what you want to do is first see the letters it says "HE" which means you count from A to Z so A1 B2 C3 D4 E5 F6 G7 H8 I9 J10 K11 L12 M13 N14 O15 P16 Q17 R18 S19 T20 U21 V22 W23 X24 Y25 Z26 so you would use that to change letter to a number. so HE is 85 SET is 19520 THE is 2085 and TEST would be 2051920

so
85
+19520
2085
----------
2051920

Sorry for over complicating it

Using simple mathematical operations, the value of TEST is 20,51,920.

What are mathematical operations?Calculating a value using operands and a math operator is referred to as performing a mathematical "operation." The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.A rule that specifies the right procedure to follow while evaluating a mathematical equation is known as the order of operations. Parentheses, Exponents, Multiplication, Division (from Left to Right), Addition, and Subtraction are the steps that we can remember in that order using PEMDAS (from left to right).

So, the value of the TEST will be:

The letter stands for the same digit everywhere it appears.We have, HE + SET + THE = TEST.

Then,

H = 8, E = 5 ⇒ HE = 85S = 19, E = 5, T = 20 ⇒ SET = 19520T = 20, H = 8, E = 5 ⇒ THE = 2085

Now,

85 + 19520 + 2085 = TEST20,51,920 = TEST

Therefore, using simple mathematical operations, the value of TEST is 20,51,920.

A fly can walk around a cubical block in two minutes. How long will it take the fly to walk along the edges of the cube from one corner to the opposite corner if it walks at the same rate?

Answers

Answer: 90 seconds or 1.5 minutes

Step-by-step explanation: 2 minutes(120 seconds) divided by 4 edges equals 30 seconds per edge. To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds

The time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a fly can walk around a cubical block in two minutes.

The time taken to cover all the one edge is,

T = 120 / 4

T = 30 seconds

To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds. Mathematically written as,

To = 3 x 30

To = 90 seconds

To = 1.5 minutes

Therefore, the time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

A gas company charges a $16 monthly service fee and $0.6924 per hundred cubic feet of natural gas used during a month. Which equation best represents Y, the gas company’s monthly charged in dollars for using X hundred cubic feet natural gas?

A. Y = 0.6924x - 16
B. Y = 16x + 0.6924
C. Y = 16x - 0.6924
D. Y = 0.6924 + 16

Answers

Numbers of phones for a gas company charges a 16 month a service

The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:

Y = 0.6924X + 16

What is an equation?

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:

Y = 0.6924X + 16

Now,

Option A has the correct variable coefficients, but the constant term is negative, which is not correct as a monthly service fee is always positive.

Option B has the correct constant term but the variable coefficient is positive, which doesn't make sense as the company charges per hundred cubic feet of natural gas used.

Option C has a similar problem as option A.

Option D has incorrect variable and constant terms.

Therefore,

The correct equation is Y = 0.6924X + 16.

Harrison and Alex are putting a fence around a field that has a perimeter of 384ft. The length is 6ft greater than 2 times the width. Find the width of the field.

Answers

a perimeter is made up of a length and width, obviously, so you can write that out algebraically as 2L+2W=P. Now, since the length is 6ft greater than 2 times the width, it can be written as 2W+6. If we plug our new L value in now, we would make the equation 2(2W+6)+2W=P. From here on out, you just gotta plug and chug.

2(2W+6)+2W=P

2(2W+6)+2W=384

4W+12+2W=384

6W+12=384

6W=372

W=62

5

= 15 + 2/

To find a new numerator:

a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/

5

= 15/

5

b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17

c) Write a previous answer (new numerator 17) over the denominator 5.

To find a new numerator:

a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/

b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21

c) Write a previous answer (new numerator 21) over the denominator 4.

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 4 = 20. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - seventeen fifths plus twenty-one quarters is one hundred seventy-three twentieths.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

What is the quotient?

When two numbers are divided by each other, the result is a quotient. For instance, when we divide 6 by 3, the result is 2, which is the quotient. An integer or a decimal number can be the quotient. We have an integer as the quotient for precise divisions, like 10 5 = 2, and a decimal for erroneous divisions, like 12 5 = 2.4.

Data set 1: Has a mean of 84 and a MAD of 6. Data set 2 Has a mean of 78 and a MAD of 8 I need to find out what the means to Mean Absolute Deviation (MAD) ratio is.

My teacher keeps telling me that it is 0.75, but I can't seem to get the right formula to it to answer right. can anyone help?

Answers

Answer:

0.75 or 6/8

Step-by-step explanation:

This is probably a late answer but I thought I would go ahead and respond.

When you have two data sets with the same variance, the ratio of the means to MAD is a way to test for the pooled variance of the two data sets

Given Data Set 1 with mean M1 and mean absolute deviation with MAD1 and another data set 2 with mean M2 and MAD2 the means to MAD ratio is given by the ratio of the absolute difference in means to the largest of the MADs

Here M1 = 84 and M2 = 78 so the absolute difference is |84-78| = 6

The larger MAD is MAD2 = 8

So the ratio is 6/8 = 3/4 = 0.75

Answers

Answer:

156

Step-by-step explanation:

Let measure of angle C = x.

Then, the measure of angle B is 14x.

14x + x = 180

15x = 180

x = 12

14x = 14(12) = 168

168 - 12 = 156

So b= 14 there isn’t any difference because B and C are the same that’s what I think so B and C are probably equal 14 and 14 or the difference that b is 14 we need to now C let’s say C is X let’s times 14time
