in circle A, AT = AE =7cm & BR= 48 CM
FIND AS
Answer:
Step-by-step explanation:
Comments
AE = AT = 7 Given
AT is a perpendicular bisector of OS Property of a circle
AE is a perpendicular bisector of BR Property of a circle
ER = 1/2 BR = 48/2 = 24 Property of a bisector
TS = ER Property of a bisector and chord
TS = 24 ER = 24 so TS = 24
AS^2 = TS^2 + TA^2 Pythagorean Theorem + rt angle
AS^2 = 24^2 + 7^2 Substitute values
AS^2 = 576 + 49 Combine
AS^2 = 625 Take sqrt of both sides
√AS^2 = √625
AS = 25
Answer
AS = 25
how did the temperature change if it decreased by 60% and then increased by 80%
Answer:
The temperature decreased by 28%
Step-by-step explanation:
How did the temperature change if :
At first it decreased by 60%
Then increased by 80%
Assume that the temperature before decreasing is 100%
∵ The temperature before decreasing = 100%
∵ It decreased by 60%
→ Before decreasing : decreasing : after decreasing
→ 100% : 60% : 100% - 60% = 40%
∴ The temperature after decreasing = 40%
Assume that the temperature after decreasing is 100%
∵ The temperature after decreasing = 100%
∵ It increased by 80%
By using the ratio method
→ After decreasing : increasing : after increasing
→ 100% : 80% : 100% + 80% = 180%
→ 40% : : x%
By using cross multiplication
∴ 100% × x% = 40% × 180%
- Divide both sides by 100%
∴ x% =
∴ x% = 72%
∵ At first the temperature = 100%
∵ At last the temperature = 72%
∵ The first the temperature > the last the temperature
∴ The decreasing in temperature = 100% - 72% = 28%
Susan's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Susan $5.45 per pound, and type B coffee
costs $4.05 per pound. This month's blend used three times as many pounds of type B coffee as type A, for a total cost of $633.60. How
many pounds of type A coffee were used?
The amount in pounds of Type A coffee used is 36 pounds.
Using equation to find the number of pounds?Type A coffee costs Susan $5.45 per pound, and type B coffee
costs $4.05 per pound.
Therefore,
Let x = the number of pounds of Type A coffee.
total pounds = x + 3x
total cost = 5.45(x) + 3x(4.05)
633.60 = 5.45(x) + 3x(4.05)
633.60 = 5.45x + 12.15x
633.60 = 17.6x
divide both sides by 17.6
x = 633.60 / 17.6
x = 36
Pounds of Type A coffee used = 36 pounds

please help! i will give u 20 points I need the answer with the method
Answer:
6 mm
Step-by-step explanation:
So, the area he needs to fill isn't really important, you don't need to calculate it. What is necessary is the individual dimensions of that area (width/length). The width and the length must be divisible by the lengths of the tiles. This is so you don't need to cut anything. For example let's say the area needed to be filled was 15 mm (width) by 10 mm (length). If I chose 3mm square tiles, it could perfectly fill up the width, but when it came to the length there would be a small 1 mm gap. And you would need to cut one of the square tiles, so it would have a length of 1 mm. In this case the 15mm was divisible by 3, but the 10 mm wasn't. So using this logic, it can't be the 4 mm square tile since 150mm / 4 mm = 37.5. It can be the 6m since 150mm / 6mm = 25 and 180 mm / 6mm = 30. It can't be the 8 mm since 150 mm / 8mm = 18.75 mm

O x- 4y = 8
O x-4y=2
O 4x-y= 8
O 4x-y=2
Answer: [tex]\frac{1}{4}[/tex]x - y = 2
Step-by-step explanation:
Standard form is Ax + By = C where A, B, and C, are integers.
Given:
y - 1 = 1/4(x - 12)
Distribute:
y - 1 = [tex]\frac{1}{4}[/tex]x - 3

y + 2 = [tex]\frac{1}{4}[/tex]x
Subtract y from both sides of the equation:

Diagram 3 shows a composite solid, formed by joining a half m-cylinder with a right prism. ABKJ is the cross - section of the right prism. MK is the diameter of the half - cylinder Given BK 28 cm, AJ = 14 and AE = 20 cm, The volume of the composite solid is 17000 cm³
Using
[tex]\pi = \frac{22}{7} [/tex]
calculate the value of h
Answer: 30 cm
Step-by-step explanation:
The volume of the composite solid is 17000 cm³. To find h, we must first subtract the volume of the half cylinder from the composite volume.
From the figure, AE = MK, and so the radius of the half cylinder is 10cm. The volume of the half cylinder is thus [tex]\frac{1}{2}[/tex] the volume of a cylinder. The volume of a cylinder is πr²h. So a half cylinder is 1/2 πr²h. This gives us a volume of [tex]\frac{1}{2} (\frac{22}{7})(10 cm)^2(28 cm) = 4400 cm^3[/tex].
Thus, the volume of the right prism is 17000cm³ - 4400cm³ = 12600cm³. Consider the cross-section ABKJ. If we multiply this by AE, we'll have the volume of the right prism.
The ABKJ is a trapezoid so it's area is [tex]\frac{1}{2}(AJ + BK) \cdot AB[/tex]. Thus the volume of the right prism is [tex]\frac{1}{2}(AJ + BK) \cdot AB \cdot AE[/tex]. This gives us [tex]\frac{1}{2}(28 + 14) \cdot h \cdot 20 = 12600[/tex], and thus h = 30 cm.

The higher or lesser the probability of an event, the more likely it is that the event will occur or not respectively. For example – An unbiased coin is tossed once.

If f is a linear function, f(0.1) = 11.5, and f(0.4) = -5.9, find an equation for the function.
Considering the expression of a line, the equation for the function that is represented through the points f(0.1) = 11.5, and f(0.4) = -5.9 is y= -58x +17.3.
Linear equation o lineA linear equation o line can be expressed in the form y = mx + b.
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.
Equation for the function in this caseIn this case, the function f(x) is represented through the points f(0.1) = 11.5, and f(0.4) = -5.9. This is:
(x1, y1)= (0.1, 11.5) (x2, y2)= (0.4, -5.9)So, the slope m can be calculated as:
[tex]m=\frac{-5.9-11.5}{0.4-0.1}[/tex]
Solving:
m= -58
Considering point 1 and the slope m, you obtain:
11.5= -58×0.1 +b
11.5= -5.8 + b
11.5 + 5.8= b
17.3= b
Finally, the equation for the function that is represented through the points f(0.1) = 11.5, and f(0.4) = -5.9 is y= -58x +17.3.
