Answer:
C
Step-by-step explanation:
Since XY = XZ = 6, then the triangle is isosceles.
The base angles are therefore congruent, that is
∠ Y = ∠ Z = 70°
The sum of the 3 angles in the triangle = 180°, thus
∠ X = 180° - (70 + 70)° = 180° - 140° = 40° → C
Answer:
Step-by-step explanation:
Wanda reaches hector at 4.5h. Wanda can not reach hector before the race ends, since at the speed he is going (16m / h) he would reach when both are at mile 72 and the race is 42 miles.
Wanda needs to increase her speed to 21m / h to catch Hector at the finish line.I attach the answers.
Answer:
Step-by-step explanation:
There are 4/7 groups of 7/4 in 1 and 3 divided by 7/4 is 12/7
<h3>How to evaluate the expressions</h3>
<u>1. How many groups of 7/4 are in 1</u>
Here, we have:
Groups = 7/4
Entity = 1
The number of groups is calculated as:
Number =Entity/Groups
So, we have
Number = 1/(7/4)
Evaluate
Number = 4/7
Hence, there are 4/7 groups of 7/4 in 1
<u>2. 3 divided by 7/4</u>
Here, we have:
Divisor = 7/4
Dividend = 3
The quotient is calculated as:
Quotient = Dividend/Divisor
So, we have:
Quotient =3/(7/4)
Evaluate
Quotient = 12/7
Hence, 3 divided by 7/4 is 12/7
