Answer: hope this helps

Step-by-step explanation:

Write down the numbers, one under the other, with the decimal points lined up.

Put in zeros so the numbers have the same length (see below for why that is OK)

Then add, using column addition, remembering to put the decimal point in the answer.

A farmer's land is separated into sections of size 3 3/4 acres. Suppose there are 2 1/5 such sections. How many acres of land does the farmer own?
Write your answer as a mixed number in simplest form.

Answers

Answer:

This is simple multiplication of fractions, not too bad!

we have 2 7/9 sections of farmland, each 2 1/5 acres large. To find the total acreage, multiply 2 1/5 by 2 7/9. The first step here is to convert to improper fractions.

To convert to improper fractions, multiply the denominator of the mixed number by the "whole number" portion of it. Then, add the numerator of the mixed number. For example, for 2 1/5, I would multiply 5 * 2 to get 10, then add 1 to get 11. Then, I keep the original denominator, so 11/5.

Let's do the same for 2 7/9. 9 * 2 = 18, then add 7 to get 25. The improper fraction is 25/9.

Now, we multiply the two fractions. This is just multiplying both numerators and both denominators, straight across.

(11*25)/(9*5) = 275/45 => 55/9, so that's the total acreage, or in decimal form, about 6.11 acres.

this is a simple equation with fractions !!

The sanctuary’s gift shop purchases items for the amounts shown in the table. Leo marks up the cost of each item by 45% to determine the gift shop’s selling price. How much would a customer pay for one pair of binoculars and one bird guide after the markup and 8.5% sales tax? Explain.

Answers

Answer:

382. 5

Step-by-step explanation:

Answer:

26.74 ($) or change currency sign to suit.

Step-by-step explanation:

Binoculars Mark up = 10x 1.45 = 14.50

Sales tax = 14.5 x 1.085 = 15.7325

Total cost per Binocular = 15.73 ($,)

Bird Guide Mark up = 7 x 1.45 = 10.15

Sales Tax = 10.15 x 1.085 = 11.01275

Total cost per Bird Guide = 11.01 ($)

One of each is found by addition.

15.73 + 11.01 = 26.74 ($) or change currency sign to suit.

Angela delivered 17 bags of ice on TuesdayShe delivered h bags of ice on Wednesday. Each bag of had a mass of 4.53 kilograms. The total mass of the bags of ice she delivered on both days was 80.42 kilograms

Answers

If the question is asking how many bags of ice cream she delivered on Wednesday, the answer would be 1. To solve the equation, you would start by calculating how many bags of ice cream she sold on Tuesday. To do this would would multiply how many bags she sold (17) by the weight of each bag (4.53 kilograms) this equation would look like 17 x 4.53 kilo = 77.01 kilo. You would then subtract it from the goal she sold on both days (80.42). This equation would look like 80.42 - 77.01 = 4.53. Meaning she sold 1 bag on Wednesday! I hope this helps!

How is solving a two-step equation similar to solving a one-step equation?

Answers

Answer:

Because it is the same concept, now u have to do more work.

For example

1+1 would be a one step equation

and

1+1(5) would be a two step equation

it's just a bit more.

Each step in solving an equation is like solving a one-step equation so solving a two-step equation is similar to solving a one-step equation

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation

We have,

Two steps equation.

Example:

2 + 3 - (3 x 4)

Step 1:

2 + 3 - 12

Step 2:

5 - 12

-7

One-step equation.

Example:

2 + 4

Step 1:

2 + 4

We see that,

Solving a two-step equation is similar to solving a one-step equation because, in the two-step equation, each of the two steps is like one step individually.

Thus,

Solving a two-step equation is similar to solving a one-step equation.

Calculate the Area of the square

Answers

Answer: 80 cm ^2

Step-by-step explanation:

Largest square = 11 by 11

Smallest square = 8 by 8

Side of triangle =

a^2 + b^2 = c^2

you can only use this formula for right angled triangles. it's called the pythagorean theory

in this case you are looking for a^2

a^2 + 8^2 = 11^2

a^2 + 64 = 144

a^2 = 144 - 64

a^2 = 80

in this case. the number isn't going to be friendly.

a = 8.9443

a is just that one side of that triangle though.

but in the end

Area of medium square = 80

because

8.9443 x 8.9443 = 80

The answer is 80cm^2

What is the equation of the graph obtained by reflecting y=3^x In the x axis

Answers

Answer:

y=-3x

Step-by-step explanation:

Shows the original equation reflected arcoss x axis

The equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .

To reflect a function in the x-axis, we change the sign of the y-values of each point on the graph. In this case, we are reflecting the function y = 3ˣ .

When we reflect y = 3ˣ in the x-axis, the equation becomes y = -3ˣ. The negative sign in front of the 3ˣ term indicates the reflection in the x-axis .

Therefore, the equation of the graph obtained by reflecting y = 3ˣ in the x-axis is y = -3ˣ .

Here’s a little review

Generic sugar which costs $2.23/kg is made by combining brand X sugar which costs $1.18/kg with brand Y sugar which costs $3.98/kg. Find the number of kg of brand X sugar and brand Y sugar required to make 40 kg of generic sugar.

Answers

Answer:

X = 14 kg

Y= 7 kg

Step-by-step explanation:

LET X and Y equal the amounts of brand X and Y

X = kg of brand X

Y = kg of brand Y

we know:

1) X + Y = 21 (kg)

2) 1X + 4Y = 2(X + Y) (This is the cost/kg * amounts for total cost)

Coefficients 1,4,2 are the cost/kg)

substitute eq. 1 (X+Y), = 21 into right side of equation 2

1X + 4Y = (21)*2

use elimination to solve 2 equations

X + Y = 21

X + 4Y = 42 (now subtract, note: I wrote the 1X as just X)

------------------

0 -3Y = -21 OR Y = 7 kg so X = (21-7) OR X = 14 kg

Please only answer if you genuinely know it.
