Answer:
222222222222224.705876
Answer:
42
Step-by-step explanation:
You would substitute B where is needs to go, 7 + 3(5) + 4(5). First multiply 3 x 5 to get 15, and then multiply 4 x 5 to get 20, 7 + 15 + 20. 7 + 15 = 22 + 20 = 42. I hope this helps.
if you where asked to solve a system of linear equations using the substitution method, what form would one or both of the equations start as that would make the problem the simplest?
A. point-slope form
B. standard form
C. slope-intercept form
D. point-intercept form
Answer:
It's A
Step-by-step explanation:
In general, the equation in point-slope form will give an expression that can substitute for "y", as that form is ...
y = [something]
_____
In specific instances, the other forms of the linear equations may work, but that is not guaranteed.
Sunita creates a scale model of an aeroplane. The scale of the model is 4 cm to 15 m. Sunita's model has a wingspan of 17 cm. What is the wingspan of the real aeroplane?
Answer:
36.43m
Step-by-step explanation:
Let the wingspan of the real aeroplane = x
The scale of the model is 4 cm to 15 m.
= 4: 15 = 4/15.
Sunita's model has a wingspan of 17cm.
Hence:
4cm/15m = 17cm/xm
Cross Multiply
4x = 15 × 17
4x = 255
x = 255/4
x = 36.428571429 m
Approximately = 36.43 m
Therefore, the wingspan of the real aeroplane is 36.43m

What is a triangle?The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.
As per the given information in the question,
The lengths of the sides of the triangle are given as,
Let Base, b = 3.6 cm
Perpendicular, p = 4.8 cm
Hypotenuse, h = 6 cm
Now, use the equation of Pythagoras' theorem,
h² = p² + b²
6² = 4.8² + 3.6²
36 = 23.04 + 12.96
36 = 36
It satisfies Pythagoras' theorem, which means that it is a right triangle.

The basking shark can grow to a length of 30 feet. This is 176.47% of the maximum length of the beluga whale. Find the maximum length of the beluga whale. If necessary, round your answer to the nearest tenth.
a) 52.9ft
b) 17ft
c) 5.9ft
d)1.7ft
Answer:
b
Step-by-step explanation:
The maximum length of the beluga whale is 17 feet.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The basking shark can grow to a length of 30 feet.
This is 176.47% of the maximum length of the beluga whale.
Assuming the maximum length of a beluga whale is x feet.
So, 176.47% of x is 30 feet.
∴ (176.47/100)×x = 30.
1.7647x = 30.
x = (30/1.7647).
x = 17 feet.
