Answer:
1) A giraffe's heart will beat 910 times in 14 minutes
Table for 1)
Beats 65 325 910
Minutes 1 5 14
2) $8.80 for 4 bags of chips
Explanation for 2)
8.8 divided by 4 equals 2.2
4.5 divided by 2 equals 2.25
Step-by-step explanation:
2L+2W= L*L+W*W= 2*2+2*2= 8
L= lenght
W= width
(the formula of a rectangle is P (perimeter) = 2W (the two widths added together) + 2L (the two lengths added together)
w=2l-p÷2; w=p-1÷2; w=p-21÷2 w=p-2w÷21????
Answer:
27
Step-by-step explanation:
3*3*3=27. 3*3=9 9*3=27
Answer:
x= -2
Step-by-step explanation:
7x+26+5x=2
7x+5x=12x
12x=2-26
12x= -24
(divide both sides by 12)
x= -2
First we need to find how far away the base of the ladder is from what it is leaning against. The ramp is the hypotenuse and the height from the ground in a leg. Let’s use Pythagorean’s theorem.
a^2 + b^2 = c^2
Substitute
a^2 + (5)^2 = (20)^2
Solve for a^2
a^2 = (20)^2 - (5)^2
Solve for a
a = 5 √15
The slope will be rise over run
5/5 √15 = √15/15 or 0.258…
