Answer:
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
Step-by-step explanation:
Let the age of Alicia be x
Let the age of Quentin be y
Let the age of Rosalyn be z
If the sum of the siblings’ ages, in years, is 48 then;
x+y+z = 48.... 1
If Rosalyn is two years older than Quentin then;
z =y+2 ..... 2
Also if Quentin is four years younger than Alicia then;
y = x-4 ... 3
From 3:
x = y+4 ... 4
Substitute 2 and 4 into 1 to have:
y+4+y+y+2 = 48
3y + 6= 48
3y = 48-6
3y= 42
y = 14
Since x= y+4
x = 14+4
x = 18
Since z = y+2
z = 14+2
z = 16year
This means that;
Alicia is 18years
Quentin is 14years
Rosalyn is 16years

About 7/10 of the surface of the earth is covered with water. Express this as an equivalent fraction with 100 as the denominator. Fraction with 100 as denominators are known as per cent 50/100 means 50 per cent. So what percentage of the earth's surface is covered with water? What percentage covered with land
Answer:
70/100
Step-by-step explanation:
Surface of the earth covered with water = 7/10
Equivalent fraction of 7/10 with 100 as the denominator = 70/100
This means 70% of the earth surface is covered with water
Percentage covered with land = Total percentage - percentage covered with water
= 100/100 - 70/100
= 100-70/100
= 30/100
Percentage covered with land = 30%

Answer:
x = 7, y = 16
Step-by-step explanation:
the sides with measure 2x + 5 and x + 12 are congruent, so
2x + 5 = x + 12 ( subtract x from both sides )
x + 5 = 12 ( subtract 5 from both sides )
x = 7
Then
x + 5 = 7 + 5 = 12
The sides with measure y - 4 and x + 5 are congruent, so
y - 4 = x + 5, that is
y - 4 = 12 ( add 4 to both sides )
y = 16

Step-by-step explanation:
In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if c=13, a=5
9514 1404 393
Answer:
b = 12
Step-by-step explanation:
A commonly seen "Pythagorean triple" is (a, b, c) = (5, 12, 13).
The value of b is 12.
__
You may be expected to find this using the Pythagorean theorem.
a² +b² = c²
b² = c² - a²
b = √(c² -a²) = √(13² -5²) = √(169 -25) = √144
b = 12
_____
Additional comment
Pythagorean triples you will run across are ...
(3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41)
and their multiples, such as 2×(3, 4, 5) = (6, 8, 10). Of course, there are an infinite number of integer Pythagorean triples, but these are ones commonly seen in algebra, trig, and geometry problems.

A. 5 m
B. 2 m
C. 19 m
D. 6 m
Answer:
D. 6m
Step-by-step explanation:
Ap3x
The height of a cone with a diameter of 12 m whose volume is 226 m^3 is 6 m
What is the cone of a height?The height of a cone is calculated using the formula:
h = 3V/πr 2
Where h = height of the cone
V = volume of the cone
r = Radius of the cone
But note that radius, r = diameter divided by 2
r = 12 ÷ 2 = 6m
Volume = 226 m^3
How to calculate the height of a coneSubstitute the values into the formula
h = 3 × 226 ÷ 3.14 × 6 × 6
h = 678 ÷ 113. 04
h = 6m
Therefore, the height of a cone with a diameter of 12 m whose volume is 226 m^3 is 6m

y = 7x-6
what is the y-intercept?
Answer:
This is in slope intercept form
y = mx + b
m is the slope b is the .y intercept so the y intercept is -6
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
We know this because the equation is y=mx+b. M represents the slope and b represents the y-intercept. In this case, -6 is in the y-intercept’s place. Therefore, we know that -6 is the y-intercept.

James is playing a dice game. He is rolling two 6-sided dice. To win, the two dice must sum to a
number greater than 7. What is the probability that he will win?
Answer:
9/20
Step-by-step explanation:
4+4=8, 4+5=9, 4+6=10, 5+5=10, 5+6=11, and 6+6=12 are the nine possible roll combinations that have a sum greater than 7 out of the possible 20 different combinations. This makes the probability of rolling a sum greater than 7 a nine in twenty chance.
