Find the area of a triangle with the following sides
Step-by-step explanation:
step 1. The easiest way is to use Herons formula.
step 2. s = (a + b + c)/2 = (3 + 5 + 6)/2 = 7
step 3. A = sqrt(7(7-4)(7-5)(7-6))
step 4. A = sqrt(7(3)(2)(1))
step 5. A = sqrt(42)
step 6. A = 6.4807 = 6.5cm^2.

Nathan buys coffee and hot chocolate for his co-workers. Each cup of coffee costs $1.75 and each cup of hot chocolate costs $1.00. If he pays a total of $14.50 for 10 cups, how many of each does he buy?
Answer:
6 cups of coffee
4 cups of hot chocolate
Step-by-step explanation:
x=number of cups of coffee
y=number of cups of hot chocolate
1.75x+1y=14.5
x+y=10 y=10-x
substitute for y
1.75x+10-x=14.5
0.75x=4.5
x=6
y=10-6=4

how many square feet of outdoor carpet will we need for this hole?
MY WORK:
First, you would cut it up into different parts/shapes
(I cut it up into rectangles)
Then, you would find the area of each.
The bottom rectangle: 10 ( 5 times 2 )
The middle rectangle: 12 ( 6 times 2 )
The top rectangle: 8 ( 4 times 2 )
Lastly, you would add!
10 + 12 + 8 = 30
Therefore, the answer is...
30!

(25-a) divided by 7=3
Answer:
a = -0.57
rounded to the nearest tenth: a = -0.6
Step-by-step explanation:
(25 - a) ÷ 7 = 3
25 - a ÷ 7 = 3
25 ÷ 7 - a = 3
3.6 - a = 3
3.57 - 3.57 - a = 3 - 3.57
a = -0.57
The value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.
To find the value of "a" in the equation (25 - a) ÷ 7 = 3.
we can solve for "a" by isolating it on one side of the equation.
(25 - a)/7 = 3.
Multiply both sides of the equation by 7 to get rid of the division:
7(25 - a)/7 = 3 × 7.
25 - a = 21.
To isolate "a," subtract 25 from both sides of the equation:
25 - a - 25 = 21 - 25.
Simplifying further, we get:
-a = -4.
Multiply both sides of the equation by -1 to solve for "a":
-1 × (-a) = -1× (-4).
a = 4.
Therefore, the value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.

Brad has a garden with dimensions 12 feet long x 7 feet wide. He wants to enlarge the garden to an area of 119 square feet. How much farther will he need to extend the length of the garden to attain his desired
Answer:
the length will need to be increased by 5 feet
He will need to 5 feet extend the length of the garden to attain his desired.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Brad has a garden with dimensions 12 feet long x 7 feet wide.
And, He wants to enlarge the garden to an area of 119 square feet.
Now,
Let the number of additional feet added to the length = x
So, We can formulate;
⇒ 7 (12 + x) = 119
⇒ 84 + 7x = 119
⇒ 7x = 119 - 84
⇒ 7x = 35
⇒ x = 5
Thus, He will need to 5 feet extend the length of the garden to attain his desired.
