Answer:
x = -4
Step-by-step explanation:
Since the slope is undefined, the line is a vertical line. All vertical lines have an equation x = k. In your problem k = -4, so the equation of the line is x = -4
Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Answer:
£15000
Step-by-step explanation:
Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Giving the ratio of inheritance 5:3:2
5+3+2 = 10
Mary's ratio = 3
Marys share = £4500
Total share x can be gotten as thus
3/10 × x = 4500
3x/10 = 4500
3x = 45000
x = 45000/3
x = 15000
Hence £15000 was there in total

Which ratio represents the cotangent of angle B in the right triangle below?
A. 5/3
B. 3/5
C. 3/4
D. 4/3
Answer:
C. 3/4
Step-by-step explanation:
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
From the diagram
Opposite = x
Adjacent = 12
tan <B = x/12
Since cot <B = 1/tan <B
cot <B = 12/x
Get x using pythagoras theorem
x² = 20²-12²
x² = 400 -144
x² = 256
x = 16
Hence cot <B = 12/16
cot <B =3/4
Lines m and n are parallel. The measure of angle 6 is 55°.
What is the measure of angle 1?
35°
55°
125°
155°
Answer:155
Step-by-step explanation:
because they are parallel lines. If the angles differed even by 1°, eventually the lines would meet, therefore they would not be parallel.
Answer:
Firstly angle 6 and 2 are equal because of corresponding angles
so 6 = 2
Now angle 1 + 2 = 180 ( linear pair)
angle 1 = 180 - 55
1 = 125
hope it helps and your day will fine

A chess club with 45 members is electing a new president. Bob received 18 votes. What percentage of the club members voted for Bob?
Given:
A chess club with 45 members is electing a new president.
Bob received 18 votes.
To find:
The percentage of the club members who voted for Bob.
Solution:
We have,
Total number of members = 45
Votes received by bob = 18
Now, the percentage of the club members who voted for Bob is
[tex]\%=\dfrac{\text{Number of members voted for bob}}{\text{Total members}}\times 100[/tex]
[tex]\%=\dfrac{18}{45}\times 100[/tex]
[tex]\%=\dfrac{2}{5}\times 100[/tex]
[tex]\%=\dfrac{200}{5}[/tex]
[tex]\%=40[/tex]
Therefore, 40% of the club members voted for Bob.

Bryan has quarters and nickels in his piggy bank. He has three times as many nickels as he has quarters. If the total value of the coins is $12, find the number of nickels in the piggy bank.
Answer:
90
Step-by-step explanation:
Quarters , q = 25 cent
Nickel, n = 5 cent
3 times as many nickels as quarters;
n = 3q
Total value of coins = $12
n + q = $12
0.05n + 0.25q = 12
0.05(3q) + 0.25q = 12
0.15q + 0.25q = 12
0.40q = 12
q = 12 / 0.40
q = 30
n = 3q
n = 3(30)
n = 90
90 nickels
Hey! I'm confused on this question It's : 3/4 - 3/10
Answer:
9/20
Step-by-step explanation:
I hope this helps :)
Answer:
9/20
Step-by-step explanation:
In order to subtract fractions you need to find the least common denominator. Since the LCD is 20 (4 times 5 or 10 times 2) you need to multiply each fraction by 1 to get the denominators the same.
3/4 times 5/5 = 15/20
3/10 times 2/2 = 6/20
now you can subtract!
15/20 - 6/20 = 9/20
you can not simplify this, so your final answer is 9/20
simplify: 3 1/8 + 1 2/3 ÷ 2/3 × 5/12
simplify: 1 1/2 - ( 8 1/3 ÷2 1/2) ÷

simplify: 1 1/4 + 2 1/2 - 1 3/4
The value of the expression [tex]3\frac{1}{8}[/tex] + [tex]1\frac{2}{3}[/tex] ÷ 2/3 × 5/12 is 17.25 and value of [tex]1\frac{1}{4} +2\frac{1}{2} -1\frac{3}{4}[/tex] is 2.
What is Fraction?A fraction represents a part of a whole.
The given expression is [tex]3\frac{1}{8}[/tex] + [tex]1\frac{2}{3}[/tex] ÷ 2/3 × 5/12
( [tex]3\frac{1}{8}[/tex] + [tex]1\frac{2}{3}[/tex])/2/3× 5/12
(25/8+5/3)/(10/36)
(75+40/24)/(5/18)
115/24×18/5
2070/120
17.25
Now [tex]1\frac{1}{4} +2\frac{1}{2} -1\frac{3}{4}[/tex]
Convert mixed fraction to improper fraction
5/4+5/2-7/4
LCM of 4, 2 is 4
(5+10-7)/4
8/4
We get 2
Hence, the value of the expression [tex]3\frac{1}{8}[/tex] + [tex]1\frac{2}{3}[/tex] ÷ 2/3 × 5/12 is 17.25 and value of [tex]1\frac{1}{4} +2\frac{1}{2} -1\frac{3}{4}[/tex] is 2.

This question is incomplete
Complete Question
If the measurement of a central angle is 5pi/6, find the length of its intercepted arc in a circle with a radius of 15 inches
a 33.4 inches
b. 35.6 inches
C. 37.5 inches
d. 39.3 inches
Answer:
d. 39.3 inches
Step-by-step explanation:
We are to find the Arc length of the circle
To solve the above question, the formula is given as:
Arc length = Central angle × radius
From the above Question, we are given:
Central angle = 5pi/6 = 5π/6
Radius = 15 inches
Hence,
Arc length = 5π/6 × 15 inches
Arc length = 235.61944901923448/ 6
Arc length = 39.26990817 inches
Approximately , the Arc length
= 39.3 inches.
Therefore, Option d is the correct answer.
