What is the measure of angle x?
Answers
Answer:
47+47+90+90= 274, 360-274= 86, 86÷2=43=x
Answer:
x = 43°Step-by-step explanation:
So here angle x is equal to the angle between 90° and 47° ( Vertically Opposite Angles are Equal.
So, if we use algebra
[tex]90 + x + 47 = 180 \\ 137 + x = 180 \\ x =180 - 137 \\ x = 43[/tex]
So the the missing angle is equal to 43

Answers
Answer:
a)29
b)70
Step-by-step explanation:
The sum of the interior angles in a triangle is 180.
a)95+56+a=180 b)40+2b=180
151+a=180 2b=180-40
a=180-151 2b=140 /2
a=29 b=70
a) 95+56+__ = 180 so the answer would be 29
Isosceles triangles have two identical angles inside that need to be the same.
b) 180-40=140 and to have two identical angles half 140 which gives you a final answer of 70
The scale on a map reads 2 inches = 125 miles.
If two cities are 4 inches apart on the map.
what is their actual distance?
Answers
Answer:
500 miles
Step-by-step Explanation:
We are told that
1 inch = 125 miles meaning if the distance between two points on the map is 1l inch, then it's 125 miles in real life. However, the map distance between the two cities is 4
inches, therefore it is 4 inches

Step-by-step explanation:
The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).
In the generic vertex form ...
f(x) = a(x -h)² +k
the letters (h, k) are used to represent the vertex.

I have an old alarm clock, on which the hands move at only 95% of the speed that they should do.
I need it to wake me up at 7.30 am, so every night, at 10.30pm, I change the time shown on the
clock so that it will show the correct time at 7.30 am when the alarm goes off.
(a) What time does the clock show at 10.30 pm, immediately before I change it?
(b) What time do I change it to?
Please help immediately!!!
Answers
9514 1404 393
Answer:
a) 9:45 pm
b) 10:57 pm
Step-by-step explanation:
In the 15 hours between 7:30 am and 10:30 pm, the clock hands will have moved 15×0.95 = 14.25 hours = 14 hours and 15 minutes.
At 10:30 pm, the clock indicates 9:45 pm.
__
b) In the 9 hours between 10:30 pm and 7:30 am, the clock will have moved 9×0.95 = 8.55 hours, or 8 hours 33 minutes. That is, the clock needs to be set 27 minutes ahead of the actual time.
The clock need to be set to 10:57 pm.
_____
Alternate solution
At 95% speed, the clock loses 5%×60 minutes = 3 minutes each hour. In the 15 hours from morning to night, the clock will be 45 minutes slow. It will indicate 9:45 at 10:30 pm.
In the 9 hours from night to morning, the clock will lose 27 minutes so needs to be set 27 minutes fast. It should be set to 10:57 pm at 10:30 pm.
Find sec x if sin x = -7/25 and cot x = -24/7.
Show work. Thanks.
Answers
Answer:
[tex]sec\ x = \frac{25}{24}[/tex]
Step-by-step explanation:
Given
[tex]sin\ x = -\frac{7}{25}[/tex]
[tex]cot\ x = -\frac{24}{7}[/tex]
Required
Determine sec x
Sec x is calculated as:
[tex]sec\ x = \frac{1}{cos\ x}[/tex]
Multiply by sin x/sin x
[tex]sec\ x = \frac{1}{cos\ x} * \frac{sin\ x}{sin\ x}[/tex]
[tex]sec\ x = \frac{1}{sin\ x} * \frac{sin\ x}{cos\ x}[/tex]
[tex]sec\ x = \frac{1}{sin\ x} * \tan\ x[/tex]
[tex]tan\ x = \frac{1}{cot\ x}[/tex]
[tex]sec\ x = \frac{1}{sin\ x} * \frac{1}{cot\ x}[/tex]
The equation becomes:
[tex]sec\ x = \frac{1}{-7/25} * \frac{1}{-24/7}[/tex]
[tex]sec\ x = \frac{-25}{7} * \frac{-7}{24}[/tex]
[tex]sec\ x = \frac{25}{24}[/tex]

There may not be an image representation of this question but I can probably answer this. If the smaller wheel causes the the bigger wheel to rotate, the wheel will rotate 30.0° about everytime. this only depends on the speed of the smaller wheel.

What is the simple interest rate on a $2300 investment paying $906.20 interest in 19.7 years?
Answers
Answer:
2%
Step-by-step explanation:
Given data
Principal=$2300
Simple interest=$906.20
Time= 19.7years
Required
The rate in percentage
We know that
SI=PRT/100
substitute
906.20=2300*R*19.7/100
906.20=45310R/100
cross multiply
906.20*100= 45310R
90620= 45310R
R= 90620/45310
R=2%
Hence the rate is 2%
