Answer:
-65/24
Step-by-step explanation:
-26/8 * 5/6 .To divide by a fraction, multiply bhy the reciprocal of that fraction. -13/4 * 5/6. Reduce the fraction with two. multiply -13/4*5/6 and you get -65/24
Yes, if you solve the problem in the parenthesis, then you add the two solutions together and you got ur final solution
Divide the scaled dimensions by 2, then multiply that by 7:
Length: 20 / 2 = 10. 10*7 = 70 feet.
Width: 10 / 2 = 5. 5 * 7 = 35 feet.
A) The pool is 70 feet long by 35 feet wide.
B) Area is length x width
Area = 70 * 35 = 2,450 square feet.
Cover cost 0.30 per square foot.
Total cost = 2,450 x 0.30 = $735
Answer:
(d) 60°
Step-by-step explanation:
<u>Theorems</u>
- Interior angles of a triangle sum to 180°
- Angles on a straight line sum to 180°
Therefore, the <u>exterior angle</u> of a triangle is <u>equal to the sum</u> of the <u>two non-adjacent interior angles</u> of the triangle.
⇒ (a + 20) + (a + 10) = (a + 90)
⇒ a + 20 + a + 10 = a + 90
⇒ 2a + 30 = a + 90
⇒ 2a + 30 - a = a + 90 - a
⇒ a + 30 = 90
⇒ a + 30 - 30 = 90 - 30
⇒ a = 60
Answer:
y = - 3x - 11
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 )
Here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (- 5, 4) into the partial equation
4 = 15 + c ⇒ c = 4 - 15 = - 11
y = - 3x - 11 ← equation of line
