Answer:
54.1%
Step-by-step explanation:
From the table, the total number of patients with type-B blood is given as 183. On the other hand, the number of males with type-B blood is given as 99. The percentage of patients with type-B blood who are males can be calculated as;
(the number of males with type-B blood/the total number of patients with type-B blood) * 100%;
( 99/183) * 100 = 54.1%
Therefore, the percentage of patients with type-B blood who are males is 54.1
Cost of the pair of jeans = $48.99
Sales tax = 6.25%
Total cost = $48.99+6.25%
= $49.05
Therefore, the total cost including sales tax is $49.05
The solution is, Sam has 5 dimes and 7 quarters.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
Sam has $2.25 in quarters and dimes, and the total number of coins is 12.
let, Sam has n₁ dimes and n₂ quarters.
then, we have,
n₁*$0.10 + n₂*$0.25 = $2.25
and, we have,
n₁ + n₂ = 12
This means that:
n₁ = 12 - n₂
And:
(12 - n₂)*$0.10 + n₂*$0.25 = $2.25
12*$0.10 - n₂*$0.10 + n₂*$0.25 = $2.25
$1.20 + n₂*$0.05*(5-2) = $2.25
$1.20 + n₂*$0.05*3 = $2.25
$1.20 + n₂*$0.15 = $2.25
n₂*$0.15 = $2.25 - $1.20
n₂*$0.15 = $1.05
n₂ = ($1.05)/($0.15)
n₂ = 7
If n₂ = 7:
n₁ + 7 = 12
Therefore, n₁ = 5.
Answer:
5 dimes and 7 quarters.

First, let's find the slope of the line using the formula , where
and
are points on the line.
The equation for the slope of this line would be:
Now, let's find use the point-slope equation to find an equation for our line, which is , where
is a point on the line and
is the slope. The point-slope equation for our line would be:
The slope-intercept form of the line would be y = -x/5 + 32/25.
Now, we can use operations to convert this equation into standard form:
The standard form of the line would be 5x + 25y = 32.
