Step-by-step explanation:
Kelli is searching for a new daycare center for her child. At Lori's Local Daycare, there is a ratio of 2 caretakers for every 7 children. If there are 189 total children, then how many people are at the daycare facility?
The ratio is given as:
Caretakers : Children
2 : 7
= In fraction = 2/7
If there are 189 total children, then how many people are at the daycare facility?
Step 1
We calculate the number of caretakers is there are 189 children
7 children = 2 caretakeras
189 children = x
Cross Multiply
7x = 189 × 2
x = 189 × 2/7
x = 54 caretakers
Step 2
The total number of people at the daycare
= 189 children + 54 caretakers
= 243 people
Answer:
The base is 6 in.
Step-by-step explanation:
21 = 1/2(7)(b)
21 = 3.5b
b = 6
Answer: 20 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case the diagonal distance covered by the stairs) and a (horizontal distance) and b (vertical distance) are the other sides.
Replacing with the values given:
25^2 = 15^2 + b^2
625 = 225 + b^2
625-225 = b^2
400= b^2
√400 =b
b =20 feet

Answer:
x^2+11x+30
Step-by-step explanation:
Since rectangles have the same length on opposite sides, The shaded area is just two congruent triangles.
A= 1/2bh
2A= 2(1/2(x+6)(x+5))
2A= (x+6)(x+5)
2A= x^2 +5x +6x+ 30
2A= x^2 +11x +30
Shaded area= x^2 +11x +30
