Answer: yes 3/5 equal to 60/100
Step-by-step explanation:
The answer is it is because if you do
5 times 20 its 100
and 3 times 20 is 60
so what you do to the bottom you do to the top
so the answer is yes 3/5 equal to 60/100
Hope this helps :)
Answer:
Yes
Step-by-step explanation:
[tex]\frac{3}{5} and \frac{60}{100}[/tex] are equivalent fractions. Equivalent fractions are fractions that have the same value of decimal. so when you simplify 60/100 you will definitely get 3/5. And both of their's decimal is equal which is 0.6.

Which values of a and b make the equation true? (2xy)^4/4xy=4x^ay^b
Answer: a=3, b=3
Step-by-step explanation:
Let's rewrite this expression on the left side so that it matched the form on the right side.
[tex]\frac{(2xy)^4}{4xy}=\frac{16x^4y^4}{4xy}=4x^3y^3[/tex]
Now, you can see the left side matches the same form as the right side.

Step-by-step explanation:
3. A telephone pole is supported by two wires on opposite sides. At the top of the pole, the wires
form an angle of 55º. On the ground, the ends of the wires are 11.0 m apart. One wire makes a
(4) 41° angle with the ground.
a) How long is each wire? (round to the nearest tenth)
b) How tall is the pole? (round to the nearest tenth)
I understand A, but please help with B ASAP!!!!
Answer: a) length of the wires are 8.1m and 13.4m
b) length of pole is 8.8m
Step-by-step explanation:
The diagram representing the scenario is shown in the attached photo. Triangle ABC is formed. Since the sum of the angles in a triangle is 180°, it means that angle B would be
180 - (41 + 55) = 84°
a) AC and BC are the lengths of each wire.
CD is the height of the pole
To determine AC, we would apply sine rule which is expressed as
a/SinA = b/SinB = c/SinC
Therefore,
11/Sin55 = BC/Sin 41 = AC/Sin84
1) 11//Sin 55 = BC/Sin 41
Cross multiplying, it becomes
11Sin41 = BCSin55
11 × 0.6561 = BC × 0.8192
BC = 7.2171/0.8192 = 8.8m
2) 11/Sin55 = BC/Sin 41 = AC/Sin84
1) 11//Sin 55 = AC/Sin 84
Cross multiplying, it becomes
11Sin84 = ACSin55
11 × 0.9945 = AC × 0.8192
AC = 10.9395/0.8192
AC = 13.4m
b) triangles ACD and BCD are right angle triangles. To determine CD, we would apply the sine trigonometric ratio.
Sin # = opposite side/adjacent side
Considering triangle ACD,
Sin 41 = CD/13.4
CD = 13.4Sin41 = 13.35 × 0.6561
CD = 8.8m
Consider the statement: “In a triangle, the measure of an
exterior angle is always greater than the measure of the
adjacent interior angle."
Which of the following would serve as a counterexample?
Answer:
See the example given in the picture attached.
Step-by-step explanation:
No options are given, so I made my own example. In the picture attached, we can see that the measure of the exterior angle A is less than the measure of the adjacent interior angle B.
On a coordinate plane, triangle L M N has points (2, 1), (1, 1), (1, 3). Triangle L prime M prime N prime has points (negative 4, negative 4), (negative 3, negative 4), (negative 3, negative 2). Which sequence of transformations produces TriangleL'M'N' from TriangleLMN? a translation 5 units down and 2 units to the right followed by a reflection across the y-axis a reflection across the y-axis followed by a translation 5 units down and 2 units right a translation 5 units down and 2 units to the left followed by a reflection across the y-axis no sequence of transformations
Answer:
(A)a translation 5 units down and 2 units to the right followed by a reflection across the y-axis
Step-by-step explanation:
If a point is reflected across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite.
Triangle LMN has points (2, 1), (1, 1), (1, 3).
Triangle L'M'N' has points (-4,-4), (-3,-4), (-3,-2).
From the given options:
Option A: A translation 5 units down and 2 units to the right followed by a reflection across the y-axis
Given the points: (2, 1), (1, 1), (1, 3) of Triangle LMN
A translation 5 units down(x,y-5): (2,-4), (1,-4), (1,-2)2 units to the right(x+2, y-5): (4, -4), (3, -4), (3, -2)Reflection across the y-axis: (-4,-4), (-3,-4), (-3,-2)Therefore, the sequence of transformation in Option A produces Triangle L'M'N'.
Answer:Which sequence of transformations produces
TriangleL'M'N' from TriangleLMN?
a reflection across the y-axis followed by a translation 5 units down and 2 units right
a translation 5 units down and 2 units to the left followed by a reflection across the y-axis
no sequence of transformations
the answer is ''A'' a translation 5 units down and 2 units to the right followed by a reflection across the y-axis.

i have no idea how to do word problems and they’re a little harder
Answer: Answer choice 1, 3, 5
Step-by-step explanation:
This is more of analyzing a graph rather than a word problem.
We are told that 4 pm is at 16 hrs after midnight. You can see that the graph increases up to 4 pm. We can say 1 is correct.
After 6 pm at 18 hrs, we can see that the graph decreases. We can say 3 is correct.
Looking at the slope of the graph, 12 to 16 has a steeper slope than 8 to 12. We can say the temperature increases faster at 12 to 16 than 8 to 12.

Answer:
The series converges to -1.5.
Step-by-step explanation:
This is a geometric series, so it converges if the number in parenthesis is between -1 and 1.
-1 < -3/5 < 1, so the series converges by the geometric series test.
Now we can plug this into the calculator (on TI-84, it's Math->0 summation) to find that the sum is -1.5. You can use 100 or another big number as a placeholder for infinity.
A flock of birds was flying around a tree. When they landed, three birds to a branch, no branches were left and one bird had to keep flying around the tree. Then, all the birds took off, flew around the tree again and landed to sit, four to a branch. Now, no birds were left flying but one branch had no birds sitting on it. How many branches were on the tree and how many birds were in the flock?
Answer: 5 branches and 16 birds.
Step-by-step explanation:
If the number of birds is B, and the number of branches is N.
First we have the equation:
B = 3*N + 1
(3 birds per branch + 1 that was flying around)
for the second equation we have:
B = 4*(N - 1)
(4 birds per branch, but one branch had no birds on it, so there are N -1 branches used)
now we can write:
3*N + 1 = 4*(N - 1)
3*N + 1 = 4*N - 4
4 + 1 = 4*N - 3*N
5 = N
So we had 5 branches, now we can replace it in one of the equations and find the number of birds.
B = 3*N + 1 = 3*5 + 1 = 16

H(4 1/2, -3 1/4) x (3 3/4, -1 3/4) what the midpoint of hx
Answer:
(3 7/8, 2 3/4)
Step-by-step explanation:
To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.
Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.
Now we have our x and y coordinates.
(3 7/8, 2 3/4)

A quadratic relation in the form y = ax² + bx + c and has a y-intercept of (0, 1). The parabola also goes through the points (2, 9) and (-5, 16). Determine the parameters of this quadratic relation (the values of a, b, and c).
Answer:
value of
a = 1
b = 2
c =1
and equation is
y = x² + 2x + 1
Step-by-step explanation:
Given quadratic equation y = ax² + bx + c
It has y-intercept of (0, 1)
thus, point (0,1) will satisfy equation y = ax² + bx + c.
putting 1 in place of y and 0 in place of x in equation y = ax² + bx + c we have
1 = a*0² + b*0 + c
c = 1
Thus, equation until now is y = ax² + bx + 1
____________________________________________________
The parabola also goes through the points (2, 9) and (-5, 16)
point (2, 9) will satisfy equation y = ax² + bx + 1.
putting 9 in place of y and 0 in place of 2 in equation y = ax² + bx + 1 we have
9 = a*2² + b*2 + 1
9 = 4a+2b+1
=>4a+2b = 9-1 = 8
dividing both side by 2 we have
4a/2+2b/2 = 8/2
=> 2a + b = 4
b = 4-2a
____________________________________________________
The parabola also goes through the points (2, 9) and (-5, 16)
point (-5, 16) will satisfy equation y = ax² + bx + 1.
putting 9 in place of y and 0 in place of 2 in equation y = ax² + bx + 1 we have
16 = a*(-5)² + b*(-5) + 1
16 = 25a-5b+1
=>25a-5b = 16-1 = 15
dividing both side by 5 we have
25a/5-5b/5 = 15/5
=> 5a - b = 3
second equation is 5a - b = 3
substituting value of b as 4-2a from first equation we have
5a - (4-2a) = 3
=> 5a - 4+2a = 3
=> 7a = 3+4 = 7
=> a = 7/7 = 1
value of b is 4-2a
substituting value of a as 1 in 4 - 2a we have
b = 4 - 2*1 = 4-2 = 2
Thus,
value of
a = 1
b = 2
c =1
and equation is
y = x² + 2x + 1
