cd + 3d2 – 2d
Give the number of terms
Answer:
3
Step-by-step explanation:
Given the expression
cd + 3d2 – 2d
We are to determine the number of terms
From the equation, the term so of the expression are cd, 3d^2 and -2d. From the listed functions, we can see that we only have three of them. Hence the number of terms in the expression is 3

Answer: 2.456 x 10^11
Step-by-step explanation:
You move the decimal to the left until there’s no more zeroes
Answer:
there :D
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

if the measures of the angles of a triangle are in the ratio 1: 2: 3 find the number of degrees in the smallest angle
Answer:
Smallest angle = 30
Step-by-step explanation:
Ratio = 1 : 2 : 3
Angles are x ,2x , 3x
Sum of all angles of triangle = 180
x +2x +3x = 180
6x = 180
x = 180/6
x = 30

Brainliest ,please help, Line L has the equation y = 5x + 12 Write down the gradient of line L
In the equation y=mx+c m= the gradient of the line and our m=5 so gradient of the line is 5
The gradient of line L is 5
What is the gradient f the line?"It is the ratio of the the change in the 'y' coordinate with respect to the change in the 'x' coordinate of that line.""It is used to calculate the steepness of a line."What is the slope-intercept form of the line?"y = mx + c, where m is the slope and c is the y-intercept."
For given question,
We have been given an equation of the line L y = 5x + 12
Comparing above equation with the slope-intercept form of the line,
we have m = 5 and c = 12
Here, slope of the line L is 5
We know that the slope of the line is the the change in the y coordinate with respect to the change in the x coordinate of the line.
This means, the gradient of the line L is 5
Therefore, the gradient of line L is 5

A jet airliner, flying initially 300 mi/hr due
east, suddenly enters a region where the
wind is blowing 100 mi/hr, pushing the
aircraft in the direction 30° north of east.
What is the resultant speed of the aircraft?
Answer:
389.82 mi/hr
Step-by-step explanation:
For us to find the resultant speed of the aircraft, we will simply add the vector components of the wind and the vector velocity of the aircraft to get;
V = v_xi^ + v_yj^
Now,
v_xi^ = (300 + 100cos30°)i^
v_yj^ = (100 sin 30°) j^
This gives;
v_xi^ = 386.6 i^
v_yj^ = 50 j^
Thus;
V = 386.6 i^ + 50 j^
Resultant velocity is;
|V| = √(386.6² + 50²)
|V| = √151959.56
|V| = 389.82 mi/hr

Carlos needs 2/3 cups of raisins to make one batch of oatmeal bars. How many cups of raisins does Carlos need to makes batches of oatmeal bars? Select the correct answer.
Answer: 2²/₃ cups of raisins.
Step-by-step explanation:
Question wants to know the number of cups needed for 4 batches of oatmeal bars.
Each batch needs 2/3 cups of raisins to make.
If there are 4 batches to be made therefore, one must multiple the 2/3 cups to make one batch by 4 to find out the number needed to make 4 batches.
= 2/3 * 4
= 8/3
= 2²/₃ cups of raisins.
