Given:
Consider a point d divides line segment ab of length 10 centimetre internally in the ratio 2:3.
To find:
The length of ad.
Solution:
If a point d divides line segment ab internally in the ratio 2:3, then the length of ad and db are 2x and 3x receptively.
We know that,
[tex]ab=ad+db[/tex]
Length of the segment ab is 10 cm.
[tex]10=2x+3x[/tex]
[tex]10=5x[/tex]
Divide both sides by 5.
[tex]2=x[/tex]
Now,
[tex]ad=2x[/tex]
[tex]ad=2(2)[/tex]
[tex]ad=4[/tex]
Therefore, the length of segment ad is 4 centimetres.
Factor the trigonometric expression

A taco charges $2.50 plus a fee of $0.05 for each mile traveled. If the ride costs $7.50, how many miles was the ride?
Answer:
100 miles
Step-by-step explanation:
7.50-2.50=5.00
100x0.05=5.00
Answer:
2.9 miles or 3 miles
Step-by-step explanation:
1. Add 2.50 & 0.05 (dont forget to line up the decimals!)
2. Divide 7.50 & 2.55
3. You then get your final answer. ( round to the nearest tenths-)

Step-by-step explanation:
Given
5x + 2y = 16 .....i)
x + 2y = 4 .....ii)
Subtracting equation I) and ii) we get
5x + 2y = 16
x + 2y = 4
- - -
4x = 12
x = 3
Putting x = 3 in equation ii)
3 + 2y = 4
2y = 4 - 3
y = 1/2
x =3 and y = 1/2
Hope it helps :)
Answer:
1) x=2 y=3 2) x=2 y=1

Answer:
1. The radius of the circle is 6cm. We know this because the radius measures from the center of a circle to the outer side. Since the radius is always half the diameter then half of 12cm is 6cm
2. The diameter is 14cm. We know this because diameter measures from one edge of a circle straight across to the other side. Also the radius is always half the diameter so 7cm*2=14cm

Answer: 0 < x < 5.6
Step-by-step explanation:
The sides of triangle:
Any two sides added together have to be larger than the third side
So:
2.8 - 2.8 < x < 2.8 + 2.8
0 < x < 5.6

g(1)= -2
g(2)= 6
g(n)=g(n−2)⋅g(n−1)
Find g(3). Show me the solutions and calculations.
Answer:
g(3) is -12
Step-by-step explanation:
Given that
g(1)= -2
g(2)= 6
g(n)=g(n−2)⋅g(n−1)
Now the g(3) is
g(3) = g(3 - 2) . g(3 - 1)
= g(1).g(2)
= (-2) (6)
= -12
Hence, g(3) is -12

Which of the expressions below has a 1 in the tenths place of the product? Select all that apply. A) 18.3 x 7 B) 6.5 x 4.31 C) 8.54 x 2.3 D) 5.4 x 2.8
Answer: A) 18.3 x 7 and D) 5.4 x 2.8
Step-by-step explanation:
A) 18.3 x 7 = 128.10
We can infer that 1 is in the tenths place.
B) 6.5 x 4.31 = 28.015
We can infer that 1 is not in the tenths place but rather the hundredths place.
C) 8.54 x 2.3 = 19.642
We can infer that 1 is not in the tenths place.
D) 5.4 x 2.8 = 15.12
We can infer that 1 is in the tenths place.
what is the side length of a square given the area to be 625m
Answer: 25 meters
Step-by-step explanation:
✓625 = 25
Answer:25
Step-by-step explanation:A square has equal length on all its sides, so the area of square is
Length x Length = 625
Which is
Length ^2 = 625
We want the number that when it times it’s self it’s 625
It can be done by square root of 625 which is 25. So the length of side is 25.
Or look at the prime factorization of 625 ( or just factors) and what number they can make up
Which is 5x5x5x5 = 625
They can make up
5^2 x 5^2 = 25 x 25 that is the “same” number
So the length is 25

what is the linear equation of a line with a rate of change of -1/2 that passes through the point (0, 4)
Answer:
y = 9/2 (fraction)
Step-by-step explanation:
y = mx+c
m = slope
c =y -intercept
Therefore, the required equation is:
y = 2x + c
Putting the point (0,4) in it as it lies on a line, we get:
4 = -1/2 + c
Therefore:
c = 9/2
So, y = 9/2

Jay bought 6 tubs of kutsinta at P70 per tub plus a delivery charge of P30. How much will she pay for her order?
Answer:
the total amount paid by her is P450
Step-by-step explanation:
The computation of the total amount paid by her is given below;
= Total cost + delivery charges
= 6 tubs at P70 + P 30
= P420 + P30
= P450
Hence, the total amount paid by her is P450
