Answer:
The required expression is,
4k + 2d
Step-by-step explanation:
Given,
She feeds her kitten k gram of food,
She feeds 2 times in the morning,
⇒ Food fed in morning = 2k,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = 2k,
So, the total food she gives to her kitten = 2k + 2k = 4k,
Now, She feeds her dog d gram of food,
She feeds 1 times in the morning,
⇒ Food fed in morning = d,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = d,
So, the total food she gives to her dog = d + d = 2d,
Hence, the total food she feeds to her animal in a day = 4 k + 2 d

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = 4 + 2 ( b + 3 )
On simplifying the equation , we get
A = 4 + 2b + 6
A = 2b + 10
Hence , the expression is A = 2b + 10

Question:
The area of a rectangular computer chip is 112a^3b^2 square microns. Write a simplified expression that represents the length, if the width is 8ab
Answer:
[tex]Length = 14a^2b[/tex]
Step-by-step explanation:
Given
[tex]Area = 112a^3b^2[/tex]
[tex]Width = 8ab[/tex]
Required
Determine the height
Area is calculated as:
[tex]Area = Length * Width[/tex]
Make Length the subject
[tex]Length = \frac{Area}{Width}[/tex]
[tex]Length = \frac{112a^3b^2}{8ab}[/tex]
[tex]Length = \frac{14a^3b^2}{ab}[/tex]
Apply law of indices
[tex]Length = 14a^{3-1}b^{2-1}[/tex]
[tex]Length = 14a^2b[/tex]

a=?
b?
Answer:
a=8 b=6
Step-by-step explanation:
Using the Pythagorean theorem, a^2+b^2=c^2, and in this case, a^2+b^2=10^2 = 100
so a^2+b^2=100
8^2+6^2=100
64+36=100 ✔
and since A is longer than B, a=8, b=6
Answer: a= [tex]5\sqrt{3}[/tex] b= 5
Step-by-step explanation:

Joshua made a quilt for his cousin's doll. The quilt had an 8 × 8 array of different color square patches. If each patch is 2 2 3 in long, what is the area of the whole quilt?
Answer:
[tex]Area = 455.11\ in^2[/tex]
Step-by-step explanation:
Given
[tex]Patches = 8\ by\ 8[/tex]
[tex]Length = 2\frac{2}{3}\ in[/tex] each
Required
The area of the quilt
First, calculate the length of the quilt.
[tex]Length = 8 * 2\frac{2}{3}[/tex]
[tex]Length = 8 * \frac{8}{3}[/tex]
[tex]Length = \frac{64}{3}[/tex]
Next, the width
[tex]Width= 8 * 2\frac{2}{3}[/tex]
[tex]Width= 8 * \frac{8}{3}[/tex]
[tex]Width = \frac{64}{3}[/tex]
The area is then calculated using:
[tex]Area = \frac{64}{3} * \frac{64}{3}[/tex] i.e. Length * Width
[tex]Area = \frac{4096}{9}in^2[/tex]
[tex]Area = 455.11\ in^2[/tex] --- approximated

Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles everyday from now on. The total number of miles walked y can be represented by y=2.5x+5 where x is the number of days walkef
Answer:
The answer is below
Step-by-step explanation:
Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles every day from now on. The total number of miles walked y can be represented by y = 2.5x + 5, where x is the number days walked after today. a. State the x- and y-intercepts and then graph the equation. b. Interpret the x- and y-intercepts.
Solution:
The equation for a linear function is given by:
y = mx + b; where m is the slope of the function and b is the y intercept.
Given the equation y = 2.5x + 5, the y and x intercept can be found by substituting x = 0 and y = 0. Hence:
a) x intercept is the value of x when y = 0. Therefore:
0 = 2.5x + 5
2.5x = -5
x = -2
y intercept is the value of y when x = 0. Therefore:
y = 2.5(0) + 5
y = 5
b) The x-intercept is at the point (–2, 0). But there cannot be a negative number of days walked, hence the x intercept does not apply in this situation.
The y intercept is at the point (0, 5). This means that Yosune has initially walked her dog 5 miles.

Pilar made 6 quarts of orange marmalade to store in jars. If she puts 1/4 quart of marmalade into each jar how many jars will she need
Answer: 24
Step-by-step explanation:
Given
Pilar made 6 quarts of orange marmalade
If each jar stores [tex]\frac{1}{4}\ \text{or}\ 0.25[/tex] quart of marmalade then
No of jars required to store marmalade is
[tex]\Rightarrow n=\dfrac{6}{\frac{1}{4}}=\dfrac{6\times 4}{1}=24\ \text{jars}[/tex]
Answer:
24
Step-by-step explanation:
Okay she got 6 quarts of orange marmalade and she pouring 1/4 quarts into a jar.
I will draw out the problem for you
1/4 + 1/4 +1/4 + 1/4 = 1 quart
1/4 + 1/4 +1/4 + 1/4 = 2 quart
1/4 + 1/4 +1/4 + 1/4 = 3 quart
1/4 + 1/4 +1/4 + 1/4 = 4 quart
1/4 + 1/4 +1/4 + 1/4 = 5 quart
1/4 + 1/4 +1/4 + 1/4 = 6 quart
and if u count all the 1/4 in the thing I just type, it will be 24

Mr. Gibbs bought number of shirts for the new members of his band. The cost for number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts did Mr. Gibbs buy?
Answer:
Number of shirts= 6
Step-by-step explanation:
Giving the following information:
The cost for several shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25.
First, we need to calculate the net total price paid for the shirts:
Net total cost= 77.49 - 3.99= $73.5
Now, the number of shirts bought:
Number of shirts= 73.5 / 12.25
Number of shirts= 6
