Step-by-step explanation:Vector C = -1.56i^ +1.07j^
This question requires that we use the properties of the scalar product of two vectors to find the required x and y component.
The dot product of two perpendicular vectors is equal to and the product of two vectors that are not parallel is equal to a nonzero value.
These are the properties that have been used in solving this problem alongside solving the simultaneous questions generator.

Answer:
Step-by-step explanation:
its 1/3, 1 to right and 3 up
Rearrange the following equation
[tex]\\ \sf\longmapsto 5.5\Delta t=1.2\Delta t^2[/tex]
Cancel Del t from both sides[tex]\\ \sf\longmapsto 5.5=1.2t^2[/tex]
[tex]\\ \sf\longmapsto t^2=\dfrac{5.5}{1.2}=4.58[/tex]
[tex]\\ \sf\longmapsto t=2.14[/tex]
angle1,2 , and angle3 form a straight line. If m angle3 is six more than twice m angle1 m angle2 is 27 less than m angle3 find m angle2
Since it's an angle on a straight line, the value of angle 2 is 23.25°
Angle 1 = m
Angle 2 = m - 27
Angle 3 = 2m + 6
It should be noted that the sum of angles in a straight line is equal to 180°, therefore we need to equate all the angles given to 180°. This will be:
m + (m - 27) + (2m + 6) = 180°
m + m - 27 + 2m + 6 = 180°
4m = 180° + 27° - 6°
4m = 201°
m = 201/4
m = 50.25°
Therefore, angle 2 will be:
m - 27 = 50.25 - 27 = 23.25°

Answer:
x = 6
∠PQR = 29
Step-by-step explanation:
Sum of interior angles in a triangle is 180,
15x - 4 + 4x + 5 + 65 = 180
15x + 4x + 5 - 4 + 65 = 180
19x + 1 + 65 = 180
19x + 66 = 180
19x = 180 - 66
19x = 114
x = 114 / 19
x = 6
∠PQR = 4x + 5
Substitute x = 6,
∠PQR = 4 ( 6 ) + 5
= 24 + 5
∠PQR = 29

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 400 nails. The contractor bought 2 more small boxes than large boxes, which altogether had 1950 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.
Answer:
The number of small and large boxes purchased are:
2 small boxes.
6 large boxes.
Step-by-step explanation:
To solve the unknowns, two equations must be established with the information provided:
150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)
Y = 3X (Large boxes are triple the small ones)
Then equation 2 is replaced in equation one and variable X is cleared:
150X + 400 (3X) = 2700
150X + 1200X = 2700
1350X = 2700
X = 2700/1350
X = 2
Finally, the value of X is replaced in equation 2 to find the number of large boxes:
Y = 3X
Y = 3 (2)
Y = 6

Marisol bought a soda for $1.99 and 6 bags of chips, which cost "m" dollars each. Which equation represents
the total amont, T, that Marisol spent?
The equation which represents the total amount, T, that Marisol spent is [tex]T = 1.99 + 6m[/tex]
Let the total amount spent be T.Let the cost of bags of chips be m.Given the following data:
Cost of soda = $1.99To find the equation which represents the total amount, T, that Marisol spent:
Translating the word sentence into an algebraic expression, we have;
6 bags of chips = [tex]6m[/tex]
The total amount is equal to:
[tex]T = 1.99 + 6m[/tex]

Answer:
false is the answer ........
Solution:
(a+b)^2 = (a+b)(a+b)= a^2 + ab + ab + b^2= a^2 + 2ab + b^2So the statement is false and the correct statement is:
For any two integers a and b, (a+b)^2 = a^2+2ab+b^2.

When x = 4, what is the value of y in the equation 3x - 2y = 6?
Answer:
The answer is 3
Step-by-step explanation:
Consider the end behavior of the function g(x)=-1/3|x|+9 and complete the statements.
As x approaches negative infinity, g(x) approaches [ Negative, Positive ] infinity.
As x approaches positive infinity, g(x) approaches [ Negative, Positive ] infinity.
Answer: thanks for this answer, I was working on this problem.
As x approaches negative infinity, g(x) approaches [ Negative] infinity.
As x approaches positive infinity, g(x) approaches [ Negative] infinity.
Let f(x)=2x-1,g(x)=3x and h(x)=x^2+1 evaluate h(-2)-f(-2)
h (-2) = (-2)^2 + 1 = 5
f (-2) = 2(-2) - 1 = -5

Answer:
36/40 or 90%
Step-by-step explanation:
First convert it to a fraction, which in this case is 36/40.
To find the percentage, we need to find an equivalent fraction with the denominator of 100. Multiply both numerator & denominator by 100.
36/40 × 100/100
= (36 × 100/40) × 1/100 = 90/100
Therefore, the answer is 90%.
If you are using a calculator, simply enter 36÷40×100, which will give you 90 as the percentage.
