Answer:
Country A has 239100 million computers and country B has 75150 computers.
Step-by-step explanation:
Let country A has number of computers = x
and the number of computers in country B = y
By the statement " Country A has 163950 million more computers than country B"
x = y + 163950 ------(1)
Another statement states " Total number of computers in both the countries is 314250 million"
x + y = 314250 --------(2)
Now we place the value of x from equation (1) to equation (2)
y + y + 163950 = 314250
2y = 314250 - 163950
2y = 150300
y = [tex]\frac{150300}{2}[/tex]
= 75150
From equation 1
x = 75150 + 163950
= 239100
Therefore, country A has 239100 million computers and country B has 75150 computers.

Roger sells fire trucks and dolls to a toy store. He sells each fire truck for $15 and each doll for $10. Roger wants to sell at least 25 toys and needs to earn at least $300 to cover his costs. If each fire truck takes 50 minutes to make and each doll takes 45 minutes to make, how many fire trucks and dolls should Roger make to minimize the time spent making the toys.
Answer:
this is the correct answer for plato (Roger should make 10 fire trucks and 15 dolls in order to minimize the time spent making toys.)
Step-by-step explanation:
Answer:
Number of Fire trucks made= 10.
Number of Dolls made = 15
Step-by-step explanation:
Let x denote the number of fire trucks made.
and y denote the number of dolls made.
Now we are given:
Roger wants to sell at least 25 toys .Hence, the inequality that can be made from this information is:
[tex]x+y\geq 25[/tex]
Also,He sells each fire truck for $15 and each doll for $10.
He needs to earn at least $300 to cover his costs.
The inequality that can be made from this piece of information is:
[tex]15x+10y\geq 300[/tex]
Also,
x≥0
and y≥0
Each fire truck takes 50 minutes to make and each doll takes 45 minutes to make.
Now we are asked to minimize the time function let it denote by 'z'.
Hence, the system that is formed is:
Optimization function Min. z=50x+45y
subject to x+y ≥ 25[/tex]
and 15x+10y ≥ 300[/tex]
Non-negative constraint x ≥ 0
y ≥ 0
Now on solving the constraints we get the boundary points as:
(25,0) , (0,30) and (10,15)
Hence, the optimal solution is checked at these points.
(25,0) z=1250
(0,30) z=1350
(10,15) z=1175
Hence, the minimal time spent is: 1175 minutes.
Number of Fire trucks made= 10.
Number of Dolls made =15

The required cost to ship her computer from store B is $28.89.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of a hundred.
We have been given that Sarah mailed her computer to Store B for repairs. Her bill was:
Initial Repair Cost = $1,350
Sales Tax of 7 percent = $94.50
Total Cost of Computer Repair = $1,444.50
We have to determine 2% of the total Cost of Computer Repair which is 1,444.50.
Shipping cost = 2% of 1,444.50
Convert percent into the fraction form,
Shipping cost = 2/100 × 1,444.50
convert the fraction into decimal form to get
Shipping cost = 0.02 × 1,444.50
Apply the multiplication operation, and we get
Shipping cost = $28.89
Therefore, the required cost to ship her computer from store B is $28.89.

The formula for glue says to add 60 mL of hardener to each container of resin. How much hardener should be added to 19 containers of resin? answer in liters
To find out how much hardener should be added to 19 containers of resin, multiply 60 mL by 19 and then divide the result by 1000 to convert mL to liters. The answer is 1.14 liters.
Explanation:To find out how much hardener should be added to 19 containers of resin, we can use the given formula of adding 60 mL of hardener to each container of resin. Since we have 19 containers, we can multiply 60 mL by 19 to get the total amount of hardener needed.
60 mL × 19 = 1140 mL
To convert mL to liters, we need to divide the amount in mL by 1000. Therefore, the answer is:
1140 mL ÷ 1000 = 1.14 liters

What is the value of b?
A 76
B 106
C 120
D 224
Answer:
The correct option is C. 120°
Step-by-step explanation:
For better explanation of the answer see the attached figure :
Since, Angle formed at the center is equal to the angle measure of its opposite arc
⇒ ∠AOD = 104°
Also, The angle formed in the segment is half the angle formed at the center of the circle
⇒ ∠DOB = 2 × ∠BAD
⇒ ∠DOB = 2 × 68°
⇒ ∠DOB = 136°
Now, ∠AOB = 360 - ∠BOD + ∠AOD
⇒ ∠AOB = 360 - 136 - 104
⇒ ∠AOB = 120°
Now, Angle formed at the center is equal to the angle measure of its opposite arc
⇒ b = ∠AOB
⇒ b = 101°
Hence, the correct option is C. 120°

what is the factors of 10
Answer: 1, 2, 5, and 10
Step-by-step explanation: To find the factors of 10, begin by dividing 10 by 1 which gives us 10. This tells us that 1 and 10 are factors of 10. Next, divide 10 by 2 which gives us 5. This tells us that 2 and 5 are also factors of 10. Next, divide 10 by 3. Notice that 10 doesn't divide evenly by 3 so 3 is not a factor of 10. Next, divide 10 by 4. Since 10 doesn't divide evenly by 4, then 4 is not a factor of 10. Next, divide 10 by 5 which gives us 2. This tells us that 5 and 2 are factors of 10 but notice that we already know that 5 and 2 are factors of 10. This means that 5 and 2 are repeat factors.
There is no need to repeat factors that we already know. In fact, as we are writing the factors of a number, it's important to understand that once we hit repeat factors, all other factors that we try will also repeat.
So here, dividing by anything greater than 5 will give us factors that we already know so we can stop here.
This means that the factors of 10 are 1, 2, 5, and 10.

Prove that if m + n and n + p are even integers, where m, n, and p are integers, then m + p is even. what kind of proof did you use?
This is about usage of direct proof.
m + p was proved to be even using direct proof.
We are given;m, n and p are integers
m + n and n + p are even integers.
From direct proof in Maths;If a is an even integer, then there will exist an integer b such that;
a = 2b
Applying that to our question, we can say that;m + n = 2b
n + p = 2c
Adding both equations together gives;m + 2n + p = 2b + 2c
We want to find if m + p is even. Thus, let's rearrange to get them on one side;m + p = 2b + 2c - 2n
Factorizing, we have;
m + p = 2(b + c - n)
From earlier, b, c and n are integers. Therefore, from earlier formula about direct proof of even integers, we can equally say that m + p is also even.

If you horizontally stretch the quadratic parent function, f(x) = x2, by a factor of 4, what is the equation of the new function?
The right answer is g(x)=(1/4x)^2 had the same question!!
Final answer:
The equation of the quadratic function f(x) = x² after a horizontal stretch by a factor of 4 is f(x) = x²/16.
Explanation:
When you horizontally stretch the quadratic parent function f(x) = x² by a factor of 4, you are stretching the function in the x-direction. This means that each x-coordinate of the graph is multiplied by the stretch factor. The new function is obtained by replacing x with x/4 in the original function. So the equation of the new function after a horizontal stretch by a factor of 4 is:
f(x) = (x/4)²
This simplifies to:
f(x) = x²/16

Identify which shapes are similar to shape A and which are not.
To determine which shapes are similar to shape A, we must evaluate the pattern, repetition, and geometrical structure, while understanding the differences in geometrical and organic forms.
Explanation:When identifying shapes similar to shape A, we must look at the pattern and repetition of the figures while noting the differences. Shapes that are similar will have proportionally equivalent angles and sides, despite potential differences in size. We analyze the given shapes by comparing their properties such as angles, sides, and overall geometrical structure.
In a more complex composition, identifying positive and negative shapes can be challenging due to the presence of implied shapes that are created by the arrangement of other shapes or colors around them. Therefore, an in-depth inspection is needed to determine similarity.
Lastly, it is necessary to understand that shapes can be geometric, like circles and squares, or organic, which are more freeform and less regular. When comparing shapes to shape A, recall that similar shapes must relate in the ways mentioned, despite their geometric or organic nature.
