Answer:
It would be 9 units.
Step-by-step explanation:
So to find the distance between two points, first start at one of the points then see how much distance there is between it and 0.
So taking 7 to start with, you would need to walk 7 units to get to 0.
However, we still need to get the distance till -2. So, we need to walk another 2 steps back, so it would be 9 units of walking in total.

Which of the following correctly displays 3 u>-2s>
Answer: (d)
Step-by-step explanation:
According to the triangle law of vector addition, the two vectors acting on a body are represented by the two sides of a triangle taken in order then the third side gives the resultant of the two vectors taken in the opposite order.
Here, option (d) aligns well with the triangle law of vector addition. The third side is in opposite order w.r.t the two vectors represented by the two sides of triangle i.e. [tex]3\vec{u}-2\vec{s}[/tex]

As part of a survey, 150 students were asked if they eat breakfast on school days. Of these students, 45 stated they eat breakfast on school days What percentage of the students in the survey stated they eat breakfast on school days?
Answer:
30 students
Step-by-step explanation:
Total number of students = 150
Of these students, 45 stated they eat breakfast on school days.
We need to find the percentage of the students in the survey stated they eat breakfast on school days. It can be calculated as follows :
[tex]\%=\dfrac{45}{150}\times 100\\\\=30[/tex]
Hence, out of 150, 30 students stated they eat breakfast on school days.

Answer:
0.98
Step-by-step explanation:
Assuming the number of questions on all the tests is 10,
9+9+10+10+10 / 50
You get 50 by doing 5 quizzes x 10 questions per quiz.
48/50 = 0.98
in the triangle DEF, angle D measures 3x, angle E measures 6x+12, and angle F measures 5x. what is the value of x
Answer:
x = 12
Step-by-step explanation:
3x + 6x + 12 + 5x = 180
14x + 12 = 180
14x = 168
x = 12
What expression is equivalent to (6•p)+3
Answer:
I am pretty sure the answer would be 6p+3
Step-by-step explanation:
I got this by solving (6 multplied by p) +3
You have to multiply 6 by p which will give you 6p
Than, you just add the +3 to the equation
This together would give you
(6*p) +3 = 6p+3.

Answer:
26.39
Step-by-step explanation:
It's a right triangle, so because of how trigonometric functions work:
[tex]\sin B = \frac{4}{9}\\B = \arcsin\frac{4}{9} \approx 26.3878^\circ[/tex]
There's really no better way than to input it into a calculator.
So the only thing left is to round to the nearest hundredth.

A rectangular block of wood measures 5 inches wide. Over time, the width of the block of wood will shrink by 5%. A builder lets the block of
wood shrink. He wants to use it to fill a gap that measures 3.5 inches wide.
How much does the builder need to cut off the wood block so that it will fit exactly in the gap? Enter the answer in the box.
The builder needs to cut
inches off the block of wood.
Answer: [tex]3.675\ in.[/tex]
Step-by-step explanation:
Given
Wood shrinks 5% over the period of time
The width of the gap is 3.5 inch
The length of the rectangular block is 5 inch
So, the builder cut the rectangular block 5% bigger to compensate for the shrinkage
Required length is
[tex]\Rightarrow 3.5+5\%\times 3.5\\\Rightarrow 3.5+0.05\times 3.5\\\Rightarrow 3.5[1+0.05]\\\Rightarrow 3.675\ in.[/tex]

Answer:
3rd option
Step-by-step explanation:
Given
y + [tex]\frac{3}{4}[/tex] = 6 ( multiply through by 4 to clear the fraction
4y + 3 = 24 ( subtract 3 from both sides )
4y = 21 ( divide both sides by 4 )
y = [tex]\frac{21}{4}[/tex] = 5 [tex]\frac{1}{4}[/tex]

a cirle has circumference 23.2 cm. What is the area of the circle? use 3.14 for pi
Answer:
42.9 cm
Step-by-step explanation:
Area of a circle is A = pi r²
to get r (radius) from circumferance. r = C/ (2 pi)
pi = 3.14
SA = 2tr2 + 2trh
(Use 3.14 for 1.) 5 in.
30 in.
Find the surface area.
square inches
Do NOT round your answer.
Given:
Radius of the cylinder = 5 in
Height of the cylinder = 30 in.
To find:
The surface area of the cylinder.
Solution:
The surface area of the cylinder is:
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=5,h=30,\pi=3.14[/tex] in the above formula, we get
[tex]SA=2(3.14)(5)^2+2(3.14)(5)(30)[/tex]
[tex]SA=2(3.14)(25)+942[/tex]
[tex]SA=157+942[/tex]
[tex]SA=1099 [/tex]
Therefore, the surface area of the cylinder is 1099 square inches.
