Answer:
135°
Step-by-step explanation:
Answer:
135 in degree measure.
Step-by-step explanation:
the angle opposite to 35 becomes also 35 by the rule vertically opposite angle. Then The traingle has three points as 100 and 35. Similarly the remaining angle becomes 45 .then 45+ unknown angle is equal to 180 by linear pair law. hence it becomes 135.....

If m = (3x-1) and n = (3x+1),sh
ow that x² = mn+1 by 9
Answer:
Step-by-step explanation:
m= (3x-1), n= (3x+1)
LHS= x²
RHS= mn+1/9
= [tex]\frac{(3x+1)(3x-1)+1}{9}[/tex]
= [tex]\frac{((3x^{2} )-1^{2})+1 }{9}[/tex]
=[tex]\frac{9x^{2} -1+1}{9}[/tex]
=[tex]\frac{9x^{2} }{9}[/tex]
=x²/1= x²
∴LHS=x²=x²= RHS
Hence proved
The tyre of a car wheel has an outer diameter of 30 cm . How many times will the wheel rotate on a journey of 5 km
Answer:
5305.1647 times
Step-by-step explanation:
The Circumference of a circle : πd
d = diameter of circle = 30 cm
Circumference of wheel = π * 30cm = 94.247779 cm
1km to cm
1km = 100000cm
5 km = 500000 cm
Hence, number of times wheel rotate on a 5km journey :
500000 cm / 94.247779 cm
= 5305.1647 times

Mrs. Smith cuts 1 2 of a piece of construction paper. She uses 1 6 of the piece to make a flower. What fraction of the sheet of paper does she use to make the flower?
Answer:
1/12 fraction of the sheet of paper is used to to make the flower
Step-by-step explanation:
The size of the piece of paper cut from the construction paper = 1/2
Amount of paper used from this piece to make flower = 1/6
Total amount of construction paper used = 1/2 * 1/6
= 1/12

Margaret and Kevin both have to write an expression that is equivalent to 6 to the power of -4. Part A Who is correct? Part B What is a possible error made by the incorrect student?
Margaret writes 6 x (1/6 to the power of 5)
Kevin writes 1/6 x (6 to the power of 4)
Please help
Answer:
Margret is correct, Kevin is wrong.
Step-by-step explanation:
6^-4 can be written as (1/6)^4
By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4
Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.

The Candy Shack sells 138 pounds of candy on Tuesday. They sold 71.76 pounds of jelly beans. What percent of the candy sold was jelly beans?
Answer:
52% were jelly beans!Explanation:
Cross multiply the following:
[tex] \frac{x}{100} = \frac{71.76}{138} [/tex]
x times 138 = 138x
100 times 71.76 = 7,176
Divide both sides by 138:
[tex] \frac{138x}{138} = \frac{7176}{138} [/tex]
x = 52%Answer:
52% were jelly beans

On the set of axes below, draw the graph of y=x^2-4x-1
9514 1404 393
Answer:
axis of symmetry: x = 2
see below for a graph
Step-by-step explanation:
You can complete the square to put the equation in vertex form.
y = (x^2 -4x +4) -1 -4
y = (x -2)^2 -5 . . . . . . vertex is (2, -5)
The equation of the axis of symmetry is the equation of the vertical line through the vertex:
x = 2 . . . . . axis of symmetry
__
Points on the graph are easily found by using integer values on either side of x=2. Points on one side of the axis of symmetry are mirrored on the other side of it.

In one basketball game, Zaid made 7 two-point and three-point baskets to score 17 points. Let x represent the number of two-point baskets, and y represent the number of three-point baskets. This situation can be represented by the system x+y=7 and 2x+3y=17 . How many of each type of basket did Zaid make?
Answer:
y =three point score = 3
x = two point score = 4
Step-by-step explanation:
this question can be solved using simultaneous equation
x + y = 7 eqn 1
2x + 3y = 17 eqn 2
Multiply eqn 1 by 2 to derive eqn 3
2x + 2y = 14 eqn 3
Subtract eqn 3 from 2 :
y = 3
Substitute for y in eqn 1
x + 3 = 7
x = 4

Suppose you make coffee and it starts off just too hot to drink, so you put it in the refrigerator temporarily to cool it off. If the original temperature is 190 degrees Fahrenheit and the refrigerator is 36 degrees Fahrenheit, what will the temperature of the coffee be after 3 minutes? (k = 0.12)
Answer:
After 2 minutes the temperature of the hot chocolate will be 149.46 degrees Fahrenheit.
Step-by-step explanation:
We are going to use the Newton's law of cooling to solve this exercise. The Newton's law of cooling states that the amount of heat lost by a body is proportional to the difference of temperature between the body and the enviroment. We are going to use the following function :
T(t)=T_{0}+(T_{i}-T_{0}).e^{-kt}T(t)=T
0
+(T
i
−T
0
).e
−kt
Where ''T(t)'' is the temperature of the body that depends of the variable ''t'' which is time.
Where T_{0}T
0
is the temperature of the surroundings
In this case T_{0}T
0
is the temperature of the freezer
Where T_{i}T
i
is the initial temperature of the body which is cooling. In this case, T_{i}T
i
is the temperature of the hot chocolate
And where ''k'' is a constant. In this case, k=0.12k=0.12 is a data of the exercise
If we replace all the values in the equation and replacing t=2minutest=2minutes
⇒
T(2minutes)=0+(190-0).e^{-(0.12).(2)}T(2minutes)=0+(190−0).e
−(0.12).(2)
T(2minutes)=(190).(e^{-0.24})=149.46T(2minutes)=(190).(e
−0.24
)=149.46
We find that the temperature of the hot chocolate after 2 minutes is 149.46 degrees Fahrenheit
