Answer:
The father is 59
Step-by-step explanation:
lets say each of the kids are twelve
30*5=150-36=114=59+55
30*5+ 150 the age of everyone in the family added together
12*3= 36 the age of all the kids
150-36=114 the age of the adults added together
we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.
2.25m + 2(2.25m) + 90 cm =
2.25m + 4.50m + 90 cm
6.75m + 90 cm
1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m
6.75m + 0.9m = 7.65m <===
OR..
1m = 100 cm....so 7.65m = 7.65 * 100 = 765 cm <===
Answer:
<em>x = -11</em>
Step-by-step explanation:
<u>Equations</u>
The image shows a right triangle with angles 70°, 90°, and x+31.
The sum of the internal angles of a triangle is 180°, thus:
70 + 90 + x + 31 = 180
Simplifying:
191 + x = 180
Subtracting 191:
x = 180 - 191
x = -11
Answer:
(x-7)²+(y+5)²=25
Step-by-step explanation:
The standard form of a circle is (x-h)²+(y-k)²=r²
(h,k) is the center
r is the radius
h=7
k=-5
r=5
(x-7)²+(y--5)²=5²
(x-7)²+(y+5)²=25
