X will be the speed of species b and 4x will be the speed of species a:
x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h
If species b has a speed of 36 m/h, the speed of species a is 4 times that:
4 x 36 = 144 m/h.

28 ounces = 793.79 grams
28 ounces = 0.79 kilograms.
Step by step explanation
1 ounce = 28.3495 grams
Now let's convert 28 into grams.
Here we have to multiply 28 by 28.3495
28 x 28.3495 = 793.787 grams
Now let's convert 793.787 into kilograms
1 kilograms = 1000 grams
793.787 grams = 0.79 kilograms
Answer:
42
Step-by-step explanation:
We use (BODMAS) :
Brackets
Order/Index
Division
Multiplication
Addition
Subtraction
Now we do bracket first :
7(3²) = 7(9) = 63
Now we do division :
63÷3 = 21
Now we do multiplication :
2 × 21 = 42
Hope this helped and have a good day
Answer:
She should have multiplied one half (4)(3.5) by 5 squared.
Step-by-step explanation:
We are given that
Base of triangle=b=4 cm
Height of triangle=h=3.5 cm
Area of triangle=
After enlarged
Scale factor=5
New base of enlarged triangle=b'=4(5) cm
Height of enlarged triangle=h'=3.5(5) cm
Area of enlarged triangle=
But Beth wrote
Area of enlarged triangle=
She should have multiplied one half (4)(3.5) by 5 squared.
