What is the value of y?
Enter your answer in the box.
Answer:
y = 20
Step-by-step explanation:
Since AB and AC are congruent then the triangle is isosceles, thus
∠B = ∠C = 25°
To find ∠A subtract the sum of the 2 angles from 180°
∠A = 180° - (25 + 25)° = 180° - 50° = 130°, thus
3y + 70 = 130 ( subtract 70 from both sides )
3y = 60 ( divide both sides by 3 )
y = 20
The function c=3x-y is minimized at the vertex point of the feasible region at (4,5). What is the minimum value
(x,y)=(4,5)
c = 3x-y = 3(4) - 5 = 7
Answer: 7
Final answer:
The minimum value of the function c=3x-y at the vertex point (4,5) of the feasible region is 7.
Explanation:
The question provided by the student involves finding the minimum value of a function of two variables, given by c=3x-y, at a certain point in the feasible region. Since the minimum is achieved at the vertex point (4,5), we can directly substitute these values into the function to find the minimum value.
To calculate the minimum value of the function c=3x-y at the point (4,5), we substitute x=4 and y=5 into the equation:
c = 3×4 - 5
c = 12 - 5
c = 7
Therefore, the minimum value of the function is 7 at the vertex point (4,5).

The coins in Diego’s pocket are worth 150% of a dollar. How much are they worth (in dollars)?
Answer:
In Diego’s pocket are worth $1.5.
Step-by-step explanation:
Given:
The coins in Diego’s pocket are worth 150% of a dollar.
Now, to find the worth in dollars in Diego's pocket.
So, as given the coins in Diego’s pocket are worth 150% of a dollar.
That means 150% of $1. As a dollar expresses 1$.
Thus, 150% of 1$.
[tex]=\frac{150}{100} \times 1[/tex]
[tex]=1.5\times 1[/tex]
[tex]=\$1.5.[/tex]
Therefore, in Diego’s pocket are worth $1.5.
Diego's coins are worth 150% of a dollar, which means they are worth $1.50. This was calculated by converting 150% to a decimal (1.50) and multiplying it by 1 dollar.
The question involves calculating the value of coins in terms of dollar amounts, which falls under the subject of Mathematics, specifically dealing with percentages and conversion of values.
Diego has coins in his pocket worth 150% of a dollar. To find out how much this is in dollars, we need to convert the percentage to a decimal by dividing by 100, which gives us 1.50. Therefore, the coins in Diego's pocket are worth $1.50. This is because 150% of 1 dollar is 1.5 times 1, which equals 1.5 or $1.50.
Remember, in math, percentages over 100% mean that you have more than the whole. So, 150% represents 1 whole (100%) plus half of another whole (50%), which in terms of dollars, translates to $1.50.

What is the area of a rectangle with side lengths of 6/8 meter and 4/ 10 meter?
Answer:
3/10 (see picture for work)
Correction:I meant to write down [tex]a=l*h[/tex], not [tex]a=b*w[/tex].The area of a rectangle with side lengths of 6/8 meter and 4/10 meter is calculated by multiplying the lengths together after simplifying them to 3/4 and 2/5, respectively. The resulting area is 0.3 m².
Explanation:To calculate the area of a rectangle, you multiply the length by the width. The question provides the side lengths as 6/8 meter and 4/10 meter. First, you may want to simplify these fractions to make multiplication easier. The fraction 6/8 simplifies to 3/4 after dividing both the numerator and the denominator by 2. The fraction 4/10 simplifies to 2/5 after dividing both the numerator and the denominator by 2.
Now, you multiply the simplified side lengths together to get the area:
Area = length × width
Area = (3/4) m × (2/5) m
Area = (3 × 2) / (4 × 5) [tex]m^2[/tex]
Area = 6 / 20 [tex]m^2[/tex]
Area = 3 / 10 [tex]m^2[/tex]
Area = 0.3 [tex]m^2[/tex]
The area of the rectangle is 0.3 [tex]m^2[/tex] (square meters).

building A has 7500 square feet of office space for 320 employees. building B has 9500 square feet of office space for 370 employees.which building offers more square feet per employee, and how much more
Building B offers more square feet per employee
Building B offers 2.2375 square feet more space for 1 employee than building A
Solution:
Building A has 7500 square feet of office space for 320 employee
Let us find the square feet needed for 1 employee
[tex]\text{ square feet needed for 1 employee } = \frac{7500 square feet}{320 employee}[/tex]
[tex]\text{ square feet needed for 1 employee } = \frac{7500}{320} = 23.4375[/tex]
Thus unit rate for building A is 23.4375 square feet per employee
Building B has 9500 square feet of office space for 370 employees
[tex]\text{ square feet needed for 1 employee } = \frac{9500}{370}\\\\\text{ square feet needed for 1 employee } = 25.675[/tex]
Thus unit rate for building B is 25.675 square feet per employee
On comparing the unit rate of both buildings, we can clearly see that Building B offers more square feet per employee
To find out how much more Building B offers more square feet per employee than building A, we can find difference between unit rates of both buildings
[tex]\rightarrow 25.675 - 23.4375 = 2.2375[/tex]
Thus Building B offers 2.2375 square feet more space for 1 employee than Building A
Final answer:
Building B offers 25.68 square feet per employee, which is 2.24 square feet more per employee than Building A, which offers 23.44 square feet per employee.
Explanation:
To determine which building offers more square feet per employee, we calculate the square footage per employee for each building:
Building A: «Building A has 7500 square feet of office space for 320 employees.
Building B: «Building B has 9500 square feet of office space for 370 employees.
Now we calculate the square footage per employee for both buildings:
For Building A: 7500 square feet / 320 employees = 23.44 square feet per employee.
For Building B: 9500 square feet / 370 employees = 25.68 square feet per employee.
Comparing the two, Building B offers more square footage per employee. To find out how much more:
25.68 - 23.44 = 2.24 square feet more per employee in Building B than Building A.
At the zoo, for every 6 adult camels, there are 5 baby camels. There are a total of 44 adult and baby camels
at the zoo.
How many baby camels are at the zoo
Answer: 20
Step-by-step explanation: For every 6 adult camels there are 5 baby camels so if you add both together, you get 11 and if you multiply that times 4 you get 44. Now you multiply 4 times the 5 baby camels to go your answer, 20.
There are 20 baby camels at the zoo.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Let x be the number of groups of adult and baby camels, each consisting of 6 adult camels and 5 baby camels. Then we know that:
The total number of adult camels is 6x.
The total number of baby camels is 5x.
The total number of adult and baby camels is 44.
Therefore, we can write the equation:
6x + 5x = 44
Simplifying, we get:
11x = 44
Dividing both sides by 11, we get:
x = 4
So there are 4 groups of adult and baby camels. To find the number of baby camels, we can multiply the number of groups by the number of baby camels in each group:
5x = 5(4) = 20
Therefore, there are 20 baby camels at the zoo.

Scientists determined that Antarctica’s average winter temperature was -34.44 Celsius. The difference between this temperature and Antarctica’s highest recorded temperature was 49.44 degrees. What was Antarctica’s highest recorded temperature?
Answer:
Antarctica's highest recorded temperature was 15 degrees.
Step-by-step explanation:
I am going to say that Antarctica highest recorded temperature is x.
I suppose there is a small typing mistake.
It is that the difference between Antarctica highest recorded temperature and this is 49.44.
So we have that x - (-34.44) = 49.44 instead of -34.44 - x = 49.44, which would lead to a highest temperature way lower than the one recorded in this winter.
Sooo
x - (-34.44) = 49.44
x + 34.44 = 49.44
x = 49.44 - 34.44
x = 15
Antarctica's highest recorded temperature was 15 degrees.

Answer:Where is the picture?
Step-by-step explanation:
The function g is defined by g(x)=cx-3, where c is a constant. Find c if the value of g(x) at x=0.5 is equal to -1
Answer:
c = 4
Step-by-step explanation:
In g(x)=cx-3 when x is set to 0.5 , g(x)= -1.
We can solve for "c" when it is the only variable in the equation.
Substitute x for 0.5 and g(x) for -1. Isolate "c" to solve by doing reverse operations.
g(x) = cx - 3
g(0.5) = 0.5c - 3 Substitute x=0.5
-1 = 0.5c - 3 Substitute g(0.5) = -1
-1 + 3 = 0.5c - 3 + 3 Add 3 to both sides to start isolating c
2 = 0.5c
2/0.5 = 0.5c/0.5 Divide both sides by 0.5 to isolate c
4 = c Value of c
c = 4 Standard formatting puts the variable on the left side
Therefore the value of c if g(0.5)=-1 is 4.
Answer:
c = 4.
Step-by-step explanation:
Substitute the given values x = 0.5 and g(x) = -1:
-1 = c(0.5) - 3
0.5c = -1 + 3 = 2
c = 2/0.5
c = 4.

an amount of $41,000 is borrowed for 7 years at 6.75% interest, compounded annually. If the loan is paid in full at the end of that year, how much must be paid back?
Answer:
We must pay back US$ 64,767.70 for the loan after 7 years.
Step-by-step explanation:
1. Let's review the data given to us for answering the question:
Loan amount = US$ 41,000
Duration of the loan = 7 years
Interest rate = 6.75% compounded annually
2. Let's find the future value of this loan after 7 years, using the following formula:
FV = PV * (1 + r) ⁿ
PV = Loan = US$ 41,000
number of periods (n) = 7 (7 years compounded annually)
rate (r) = 6.75% = 0.0675
Replacing with the real values, we have:
FV = 41,000 * (1 + 0.0675) ⁷
FV = 41,000 * (1.0675) ⁷
FV = 41,000 * 1.5797
FV = US$ 64,767.70
We must pay back US$ 64,767.70 for the loan after 7 years.

Answer:
(a) 24 cents.
(b) The slope is: [tex]24[/tex]
Step-by-step explanation:
(a) Notice that the x-axis is labeled as "Weight (ounces)" and the y-axis is labeled as "Cost (cents)".
You can identify that when:
[tex]x=1;y=24[/tex]
[tex]x=2;y=48[/tex]
[tex]x=3;y=72[/tex]
Then, you can determine that the cost of the cheese increases 24 cents for each ounce Dale buys.
(b) The slope can be found with the following formula:

find the scale factor.
The scale factor is 1.5. The dilation rule is : (x,y)-------(.15x,1.5y)
Step-by-step explanation:
Dilation is a transformation that maps an object to an image of the same shape as the original object to form a different size image.When a larger image is produced it's called an enlargement where as when a small image is produced, it's called a reduction.
The rule of dilation, with center as the origin follows;
(x,y)------(sx,sy) where s is the scale factor. To find the scale factor, select one of the vertices of the object and of the image at divide the coordinate of image with that of object.
Taking O(2,16) and O'(3,24), the scale factor will be;
s*2=3
2s=3
s=3/2 =1.5
or
s*16=24
16s=24
s=24/16=3/2=1.5
The scale factor is 1.5, hence the dilation rule is;
