Answer: [tex]\$1450[/tex]

Step-by-step explanation:

Given

Landon earns a 10% commission on his total sales

Suppose his total sales is x to get a commission of $145 i.e.

[tex]\Rightarrow x\times 10\%=145\\\Rightarrow 0.1x=145\\\Rightarrow x=\$1450[/tex]

Therefore, the amount of total sales must be $1450

Answer:

Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:

P is the price of the cake

S is the number of servings

Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)

In turn, 10 is the fixed cost of each cake.

Answer:

b=54

Step-by-step explanation:

b=14(3)+12

b=42+12

b=54

Hey there!

b = 14j + 12

TURN the EQUATION

14j + 12 = b

j = 3

NEW EQUATION: 14(3) + 12

14(3) + 12

14(3) = 42

42 + 12 = b

SIMPLIFY ABOVE and you will have your answer of b

42 + 12 = 54

Therefore your answer is: b = 54

Good luck on your assignment and enjoy your day!

Answer:

5 kg 800 grams

5800g

Step-by-step explanation:

the first step is to convert 1kg to gram

100 kilogram = 1 gram

1kg x 1000 = 1000g

1kg 160 gram = 1000 + 160 = 1160 gram

If 1 sack weighs 1160 g

5 sacks = 1160g x 5 = 5800 gram

or 5800 / 1000 = 5 kg 800 grams

Answer:

A. 50.38

Step-by-step explanation:

Bill is 38.96. Calculate sales tax: 38.96x.0775=3.02.

38.96 + 3.02=41.98 total before tip

41.98x.20=8.40 tip

41.98 + 8.40=50.38

Answer:

y=-6/5x -8

Step-by-step explanation:

slope is the same as gradient(m) so find the c in the equation y=mx+c using the point (-5,-2) which gives u -8 then substitute values of m and c in that very equation

Answer:

[tex]y=-\frac{6}{5}x-8[/tex]

Step-by-step explanation:

Same process as the other two lol

y= -(6/5)x+b

solve for b by plugging in the required coordinates

-2= -(6/5)(-5)+b

-2= 6+b

-8=b

put it all together

Answer:

blue line : y = 3

black horizontal line : y = 0

black vertical line : x = 0

Step-by-step explanation:

it is really simple.

blue line : no matter what value we pick for x, the functional value for y is always 3. and that defines the equation y = 3 + 0*x or simply y = 3.

the same with the black horizontal line. the difference is that y is now always 0. so, y = 0.

Answer:

-525 it is now 525 below sea level

Step-by-step explanation:

I'm kinda confused the question is weird to me so I don't know if this is right

Answer:

y = -1

Step-by-step explanation:

I'll solve for "y" since there is no "x"

First expand the numbers inside the parenthesis by multiplying -4

-4y  + 8 =12

Subtract 8 from both sides to isolate -4y

-4y = 4

divide both sides by -4 to get "y"

y= -1

Lol i dont know

hehe

Answer:

4/10

Step-by-step explanation:

4/10 = 0.4 = 0.40

2/6 = 0.33

so, 0.40 is greater than 0.33

Explanation:

We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.

Add up the values along the bottom row. Set the sum equal to 50 and solve for m

m+8+29 = 50

m+37 = 50

m = 50-37

m = 13

Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.

Answer:

A - 13

Step-by-step explanation:

50 (8th graders) - 8 (tiling lovers) - 29 (carpeting lovers) = 13 (wooden floor lovers)

Answer:

Six letters---6

Step-by-step explanation:

The solution is, the letters in the word GRADE can be arranged in 120 ways.

In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.

here, we have,

Given that we are to evaluate the number of ways to arrange the letters in the word GRADE,

In the word GRADE, we have 5 distinct letters:

G(1), R(2), A(3), D(4), E(5).

There are 5 letters.

Thus, the number of ways of arranging the letters is evaluated as

5! = 1×2×3×4×5

   =120

Hence, the letters in the word GRADE can be arranged in 120 ways.

Answer:

Photosynthesis is

Step-by-step explanation:

The process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Hope this answered your question :)

Answer:

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer:

804.2

Step-by-step explanation:

what ? you cannot use a calculator ? it is all there, you only need to type it in.

the only point, where you need to "think" is the difference between radius and diameter. because the graphic gave you the diameter, and the formula asks for the radius.

so ... ... ... ... did you figure it out ?

the radius is half of the diameter, so, 8ft in this example.

S.A. stands for "Surface Area".

so, now, again, we only need to type it into the calculator.

[tex]4 \times \pi \times {8}^{2} [/tex]

[tex]4 \times \pi \times 8 \times 8[/tex]

[tex]4 \times \pi \times 64[/tex]

and the result 804.2477...

rounding it to the nearest tenth (you know, the first position after the comma) is then 804.2

you really needed help with that one ?
