The value of x in the triangle is 70°
<h3>What is a scalene triangle?</h3>
A scalene triangle is a plane figure that has 3 different length sides and 3 different angles. The sum of all the angles in a scalene triangle is equal to 180°
i.e
- Let's assume that angle y = 60° and angle z = 50°
Then;
x + 110° =180°
x = 180° - 110°
x = 70°

Answer:
<h2>$12.6</h2>
Step-by-step explanation:
Step one:
given that the dimensions are
length=3cm
width=4cm
hieght= 7cm
the volume of the pool is= lwh
volume=3*4*7= 84cm^3
Step two:
the cost of filling
we are told that 1cm^3 will cost $0.15
hence 84cm^3 will cost x
cross multiply
x= 0.15*84
x=12.6
<u>The cost of filling the pool will be $12.6</u>
Answer:
-0.385
Step-by-step explanation:
Answer: $2520
Step-by-step explanation:
The simple Interest earned on a deposit of P that has a rate of r% and a period of t years can be calculated by using the formula:
(P × R × T)/100
where P is principal
R is rate
T is time
P=$10,500
R=6%
T=4 years
Therefore:
Interest= (10500 × 6 × 4)/100
= 252000/100
= 2520
Sally will earn $2520 as interest after 4 years.
3t -7 = 5t
Minus 3t over
-7= 2t
t= -7/2
6(t) = 6(-7/2) = -42/2 = -21
6t = -21
