Step-by-step explanation:
Gold and silver are mixed in the ratio 7:4.if 36gm of silver is used.How many gold is used
Answer:
63gm
Step-by-step explanation:
7 gold : 4 silver
It gives you 36 silver.
to get from 4 silver to 36 silver you multiply by 9.
you multiply the gold by the same amount 9.
7*9= 63
you can see that for every 7 gold pieces there is 4 silver pieces. they keep piling up the pieces until there's 36 silver pieces. now they wanna know how much gold there is.

Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (- 1, 2) ← 2 points on the line
m = [tex]\frac{2-1}{-1-(-2)}[/tex] = [tex]\frac{1}{-1+2}[/tex] = [tex]\frac{1}{1}[/tex] = 1
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = x + 2 ← equation of line
What is the equation of the line that passes through the point (5, 4) and is perpendicular to the line whose equation is 2x + y = 3 in standard form?
So a line that is perpendicular is a line that intercepts other line at a 90 degree angle.
Slope of perpendicular lines is the opposite sign and the reciprocal of the other.
So if your slope was 2 the perpendicular line would have a slope of -1/2.
So the equation, 2x + y = 3
Can be rewritten as
y= -2x+3
Perpendicular slope: 1/2
Since it intercepts/ passes the coordinates (5,4) it means that those values are included in the function input x and output y.
y=mx+b
4=1/2(5)+b
Solve for b (y intercept)
4-2.5=b
1.5=b
So the equation of the perpendicular is
y=1/2x+3/2 or y=.5x+1.5

$400 at 6.3% for 4 years. Find the simple interest
Answer:
the amount of interest is $100.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6.3%/100 = 0.063 per year,
then, solving our equation
I = 400 × 0.063 × 4 = 100.8
I = $ 100.80
The simple interest accumulated
on a principal of $ 400.00
at a rate of 6.3% per year
for 4 years is $ 100.80.

Answer: -5 and -7
Step-by-step explanation:
|[tex]\frac{x}{2}[/tex]+3| = [tex]\frac{1}{2}[/tex]
It has 2 cases
the first case ;
[tex]\frac{x}{2}[/tex] + 3 = [tex]\frac{1}{2}[/tex]
[tex]\frac{x}{2}[/tex] = [tex]\frac{-5}{2}[/tex]
x = -5
the second case;
[tex]\frac{x}{2}[/tex] + 3 = [tex]\frac{-1}{2}[/tex]
[tex]\frac{x}{2}[/tex] = [tex]\frac{-7}{2}[/tex]
x = -7

What is the answer for x?
Answer:
Step-by-step explanation:
The triangle’s angles add up to 180 degrees
so 40 + (16x + 2) + ∠C = 180
The straight angle is 180°
so ∠C = 180 - (23x + 7)
∠C = 180 - 23x -7
∠C = 173 - 23x
and then 40 + (16x + 2) +(173 - 23x) = 180
40 + 16x + 2 + 173 - 23x = 180
215 - 7x = 180
-7x = 180 - 215
-7x = -35
x = 5

To approximate the length of a lake, a surveyor starts at one end of the lake and walks 245 yards. He then turns 110 and walks 270 yards until he arrives at the other end of the lake. Approximately how long is the lake?
Answer:
Surveying To approximate the length of a marsh, a surveyor walks 250 meters from point to point , then turns and walks 220 meters to point (see figure). Approximate the length of the marsh.
hope it helped
Step-by-step explanation:
The approximate length of the lake is 625 yards.
Given that, a surveyor starts at one end of the lake and walks 245 yards.
What is total?A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.
He then turns 110 and walks 270 yards until he arrives at the other end of the lake.
Total length of the lake is
245+110+270 =625 yards
Therefore, the approximate length of the lake is 625 yards.

part B
[tex] \frac{12}{25} . \: \frac{15}{16} \\ \\ \frac{9}{20} \\ \\ 0.45[/tex]
Answer:
8/21 . 5/16 = 5/42
12/25 . 15/16 = 9/20
Step-by-step explanation:
16 = 2 x 8
8/21 . 5/16
= ( 8 x 5 ) / ( 21 x 16 )
= ( 8 x 5 ) / ( 21 x 2 x 8 )
= 5 / ( 21 x 2 )
= 5/42
12 = 3 x 4
15 = 3 x 5
25 = 5 x 5
16 = 4 x 4
12/25 . 15/16
= ( 3 x 4 ) / ( 5 x 5 ) . ( 3 x 5 ) / ( 4 x 4 )
= ( 3 x 4 x 3 x 5 ) / ( 5 x 5 x 4 x 4 )
= ( 3 x 3 ) / ( 5 x 4 )
= 9/20
