Answer:
15.6
Step-by-step explanation:
15+32=47
47/3=15.6
since the - is there
it will be -15.6
Answer:
2.30
Step-by-step explanation:
The side of interest is opposite the given angle, and the hypotenuse is given. The sine relation tells you ...
sin(A) = a/c
a = c·sin(A) = 3·sin(50°)
a = BC ≈ 2.2981 ≈ 2.30
Answer:
Step-by-step explanation:
1680 mile road trip....they completed 3/8 of it...
so we need to figure 3/8 of 1680
" of " in math language means multiply
3/8 * 1680 = 5040/8 = 630 miles <===
<span>Width = 6
Length = 30
We know the perimeter of a rectangle is simply twice the sum of it's length and width. So we have the expression:
72 = 2*(L + W)
And since we also know for this rectangle that it's length is 6 more than 4 times it's width, we have this equation as well:
L = 6 + 4*W
So let's determine what the dimensions are. Since we have a nice equation that expresses length in terms of width, let's substitute that equation into the equation we have for the perimeter and solve. So:
72 = 2*(L + W)
72 = 2*(6 + 4*W + W)
72 = 2*(6 + 5*W)
72 = 12 + 10*W
60 = 10*W
6 = W
So we now know that the width is 6. And since we have an expression telling us the length when given the width, we can easily determine the length. So:
L = 6 + 4*W
L = 6 + 4*6
L = 6 + 24
L = 30
And now we know the length as well.</span>
<span>Give the Algebraic expression for the difference of 10 and u.
Algebraic expression is the expression that contains the combination of number, variables and operators like addition, division, subtraction and multiplication.
In the given expression we need to convert it into algebraic expression.
=> expression of the difference of 10 and u
=> difference = result of subtraction
=> 10 is the number to be subtracted by u
=> u = is the unknown number to subtract to 10
=> 10 – u
