AC = CB, hence ΔABC is isosceles
the base angles 34 and x - 5 are therefore equal
x - 5 = 34 ( add 5 to both sides )
x = 39
and 4y = 180 - ( 2 × 34 ) = 112
4y = 112 ⇒ y = 28
Answer:
x=39° ,y=28°
Step-by-step explanation:
In the given figure
Side AC = Side BC
Hence ΔABC is an isosceles triangle.
⇒∠CAB =∠CBA (∵ angles opposite to equal sides are equal)
⇒ (x - 5)° = 34°
⇒ x = 39
Also in Δ ABC
∠ABC + ∠ACB + ∠CAB = 180°
(∵ Sum of all the interior angles of a triangle)
⇒ 34° + 34° + 4 y = 180°
⇒ 4 y =180°-68°
⇒ y=112°÷ 4
⇒y= 28°
Hence, x = 39° , y = 28°

Mr. Glidden is expanding the size of his garden. His new garden will be 3 times as long and 2 times as wide as his original garden. The perimeter of his original garden is 30 feet and the length is 11 feet. What will be the perimeter, in feet of his new garden?
Method One:
Step One: Figure out how long the width is, witch is 19 feet.
Step Two: Multiply 2*19 and 3*11 because it is 2 times as long and three times as wide
Step Three: Add 38+33
The new perimeter will be 71 feet.
The original garden's width is determined to be 4 feet. Upon expanding the garden to triple its length and double its width, the new garden's perimeter is calculated to be 82 feet.
The question is about calculating the perimeter of a new garden based on given dimensions and scale factors for its expansion. The original garden has a perimeter of 30 feet and a length of 11 feet. To find the width, we use the formula for the perimeter of a rectangle, P = 2l + 2w, which gives us 30 = 2(11) + 2w. Solving for w, we find that the width of the original garden is 4 feet.
Given that Mr. Glidden is expanding his garden to be 3 times as long and 2 times as wide, the new dimensions will be 3(11) feet by 2(4) feet, or 33 feet by 8 feet.
Therefore, the new perimeter will be 2(33) + 2(8), which equals 66 + 16, resulting in a new perimeter of 82 feet.

if 75 is added to a number, the result is 39 less than three times the number.find the number
First, we would set the number to x.
Then, we turn the words into an equation.
x+75 = 3x-39
Isolate the x.
-2x = -114
So...
x = 57
The Number is 57.
Let's call the number you're trying to find "x."
According to the information given, if 75 is added to x, the result is 39 less than three times the number, which can be expressed as:
x + 75 = 3x - 39
To solve for x, you can first get all the x terms on one side of the equation and the constant terms on the other side:
75 + 39 = 3x - x
Now, simplify the equation:
114 = 2x
To isolate x, divide both sides by 2:
x = 114 / 2
x = 57

8x + 3 = 4x + 7
Subtracting 3 from both sides;
8x + 3 - 3 = 4x + 7 - 3
8x = 4x + 4
Subtracting 4x from both sides;
8x - 4x = 4x + 4 - 4x
4x = 4
Dividing by 4 on both sides;
4x/4 = 4/4
x = 1
Hence, option A is correct i.e. x = 1.

The top of a refrigerator has an area of 0.6 m^2. The height of the refrigerator is 180 CM. What volume does the refrigerator occupy in CUBIC METERS?
Note: all measurements of the refrigerator need to be in meters, make sure you have IDENTICAL units.
SHOW WORK PLEASE
THANKS IN ADVANCE! :)
the volume (V ) of a cuboid is V = Ah
where A is the area of the base or top and h is the height
h = 180 cm = 1.8m
V = 0.6 × 1.8 = 1.08 m³
The volume of the refrigerator is calculated by converting its height from centimeters to meters (180 cm = 1.8 m) and then multiplying it by the given area of the top (0.6 m²), resulting in a volume of 1.08 cubic meters.
To calculate the volume of the refrigerator, we need to use the formula for the volume of a rectangular prism, which is Volume = length x width x height. We already have the area of the top of the refrigerator, which is a product of its length and width, and we're given the height. However, firstly we need to ensure that all units are in meters.
Convert the height from centimeters to meters: 180 cm = 1.8 m.
Now, we can calculate the volume: Volume = Area x Height = 0.6 m² x 1.8 m = 1.08 m³.
Therefore, the refrigerator has a volume of 1.08 cubic meters.

Rubin has 6 rolls of pennies containing 50 coins each, 5 rolls of nickels containing 40 coins each, 4 rolls of dimes containing 50 coins each l, and 3 rolls of quarters containing 40 coins each. How much money does he have?
6•50=$3.00 pennies
5•40=$2.00 nickels
50•10=$5.00 dimes
25•40=$10.00 total $20.00
Answer: $63
Step-by-step explanation:
Penny = $0.01
Nickel = $0.05
Dime = $0.1
Quarter= $0.25
Number of pennies = 6(50) = 300
Number of nickels = 5(40)= 200
Number of dimes = 4(50)= 200
Number of quarters = 3(40) = 120
Total amount of money:
300(0.01)+ 200(0.05) + 200(0.1) + 120(0.25) = $63

The scores on a psychology exam were normally distributed with a mean of 57
and a standard deviation of 4. A failing grade on the exam was anything 2 or more standard deviations below the mean. What was the cutoff for a failing score? Approximately what percentage of the students failed?
Answer:
Cutoff for a failing score is 49 and 2.28% students failed.
Step-by-step explanation:
We have been given that scores on a psychology exam were normally distributed with a mean of 57 and a standard deviation of 4.
2 standard deviation below mean would be,
[tex]57-2(4) =57-8= 49[/tex]
Therefore,Cutoff far a failing score is 49.
Now let us find out the z-score for our given values,
[tex]z=\frac{x-\mu}{\sigma}[/tex]
[tex]z=\frac{49-57}{4}=\frac{-8}{4} =-2[/tex]
Now let us look up the probability from normal distribution table.
[tex]P(z<-2) =0.02275[/tex]
Therefore, percentage of students failed is 2.28%.

Ding three consecutive even integers such that the sum of twice the smallest and three times the largest is 42
Answer:
6,8,10
Step-by-step explanation:
Two consecutive even integers would have difference of 2
Hence we can assume the three consecutive integers to be of the form
a-2, a and a+2
Smallest number = a-2 and
Largest number = a+2
Twice the smallest number + 3 times largest number =42 (given)
2(a-2)+3(a+2) = 42
2a-4+3a+6 =42
5a +2 =42
Subtract 2 and then divide by 5
5a = 40 and a = 8
Hence the three numbers are 6,8 and 10
one number is three less than four times another. if their sum is decreased by seven, the result is twenty. find the numbers
x = 21
y = 6
x = 4y - 3
x + y - 7 = 20
Because we have a value for x, we can put it in the second equation to find the value of y.
4y - 3 + y - 7 = 20
Combine like terms.
5y - 10 = 20
Add 10 to both sides.
5y = 30
Divide both sides by 5.
y = 6
Now we can place this value of y back into the equation to find the exact value of x.
x + 6 - 7 = 20
Combine like terms.
x - 1 = 20
Add 1 to both sides.
x = 21

The expression y = kx can be used to find the value of y when x is given. In this case, the value of y when x is 2 is 16.
Explanation:To find the expression to determine the value of y when x is 2, we need to use the fact that y varies directly as x. This can be represented by the equation y = kx, where k is the constant of variation.
We are given that when x is 6, y is 48. Plugging these values into the equation, we have 48 = k * 6. Solving for k, we find that k = 8.
Now we can use this value of k in our equation to find y when x is 2. Substituting 8 for k and 2 for x, we have y = 8 * 2 = 16. Therefore, the value of y when x is 2 is 16.
