Answer:
2.7
Step-by-step explanation:
Using PEMDAS you do 2-1.1 first which is is 0.9 then you multiply it by 4 you get 3.6 and then you subtract that by 6.3 and you get 2.7
Answer: 2.7
Use PEMDAS method.
The function f(x) = 3.r4 + kx3 + x – 2 has an x-intercept at x = -2.
What is the value of k in the function f(r)?
O A
2
B.
13
2
C. -3
D. 7
Answer:
Choose (A)
Step-by-step explanation:
f(x)=3x⁴+kx³+x-2
f(x)=3(-2)⁴+k(-2)³+(-2)-2
=-8k+44
-8k=-44
k=44/8
k=11/2
There are two numbers whose product is 117 and quotient is 13. What are the two numbers
Answer:
Let the two numbers be x and y
Step-by-step explanation:
Given :
x × y = 117 -1
x ÷ y = 13 -2
from equation 2 ,
x = 13×y -3
putting value of x from equation 3 in equation 1
13y × y = 117
13y² = 117
y² = 117 / 13
y² = 9
y = √9
y= 3
putting value of y in equation 3
x = 13 × y
13× 3
= 39
hence the two numbers are 39 and 3

3. A cubical wooden box has a surface area of 600 square cm. What is the measurement
of each
edge?
B. 6 cm
C. 10 cm
A. 5 cm
D. 100 cm
Answer:
C)
B)
C)
Step-by-step explanation:
Question-1:recall the surface area formula of cylinder
[tex] \displaystyle A _{S} = 2\pi r(h + r)[/tex]
given that,h=5 and r=0.7
substitute:
[tex] \displaystyle A _{S} = 2\pi (0.7)(5 + 0.7)[/tex]
simplify parentheses:
[tex] \displaystyle A _{S} = 2\pi (0.7)(5 .7)[/tex]
simplify multiplication:
[tex] \displaystyle A _{S} =25.0572 sqm[/tex]
hence, our answer is C
Question-2:remember the surface area formula of cone
[tex] \displaystyle A _{S} = \pi r(r + s)[/tex]
given that,r=7 and s=10
substitute:
[tex] \displaystyle A _{S} = \pi (7)(7+ 10)[/tex]
simplify parentheses:
[tex] \displaystyle A _{S} = \pi (7)(17)[/tex]
simplify multiplication:
[tex] \displaystyle A _{S} =373.66sqcm[/tex]
hence, our answer is B
Question-3:now for the question-3 we need a little bit understanding
remember the surface area formula of cube
[tex] \displaystyle A _{S} =6 {a}^{2} [/tex]
we are given that,[tex]A_S=600[/tex] Thus
substitute:
[tex] \displaystyle 6 {a}^{2} = 600[/tex]
divide both sides by 6:
[tex] \displaystyle {a}^{2} = 100[/tex]
square root both sides:
[tex] \displaystyle {a}^{} = 10[/tex]
hence, the measurement of each
edge is 10 cm therefore our answer is C)

4. A representative sample of 50 students from a high school is surveyed. Each student is asked what science class
he or she is taking. This table show the responses. Select all the statements that are valid based on the results of
the survey.

Chemistry
Biology
Earth Science
Health Science
Number of
Students

18
A. About 20% of students at the high school are taking
Chemistry.
B. About twice as many students are taking Health Science
than are taking Physics.
C. For every 150 students we could predict that at least 18
of the students are taking Physics.
D. For every 25 students we could predict that at least 4 of
the students are taking Earth Science.
4
12
Answer:
A, B, C
Step-by-step explanation:
The total number of students is the sum of the students taken each course. Hence the total number of students is:
Total number = 6 + 10 + 18 + 4 + 12 = 50 students
A) The percentage of students offering chemistry = (number of students offering chemistry / total number of students) * 100%
percentage of students offering chemistry = (10 / 50) * 100% = 20%
Option A is correct
B) number of students taking health science = 12, while number of students taking physics = 6. Hence About twice as many students are taking Health Science than are taking Physics.
Option B is correct.
C) The percentage of students taking physic = (6 / 50) * 100% = 12%
Therefore for 150 students, the number of students taking Physics = 12% * 150 = 0.12 * 150 = 18
Option C is correct
D) The percentage of students taking earth science = (4 / 50) * 100% = 8%
Therefore for 25 students, the number of students taking earth science = 8% * 25 = 0.08 * 25 = 2
For every 150 students we could predict that 18 of the students are taking Physics.
Option D is correct

Answer:
Equation to solve for "x": 90 + x + x + 18 = 180
x = 36
Step-by-step explanation:
90 + x + x + 18 = 180
90 + 18 + 2x = 180
108 + 2x = 180
(108 - 108) + 2x = 180 - 108
2x = 72
2x/2 = 72/2
x = 36
90 + 36 + 36 + 18 = 180
108 + 72 = 180
180 = 180

Gavin wants to buy a bike which costs 1,000 dollars. He raised 250 so far from his shoe shop. How much more does Gavin need to raise in order to buy the bike?
Answer:
the answer would be 750 dollars.
Step-by-step explanation:
If he needs $1,000 in total and already has $250, you can do 1,000 - 250 to get 750. A simpler way to.do that could be to take 1,000 - 200 to get 800, and then subtract another 50.

Answer:
Exact Area = 210.25pi - 210Approximate Area = 450.185The units for the area are in square inches or in^2. The approximate value shown above is when using pi = 3.14
=============================================================
Explanation:
Use the pythagorean theorem to find the length of the hypotenuse
a = 20b = 21c = unknowna^2 + b^2 = c^2
20^2 + 21^2 = c^2
400 + 441 = c^2
c^2 = 841
c = sqrt(841)
c = 29
The hypotenuse is 29 inches long. This is the diameter of the circle. Half of that is the radius at r = d/2 = 29/2 = 14.5 inches.
The area of the circle is...
A = pi*r^2
A = pi*(14.5)^2
A = pi*210.25
A = 210.25pi
Which is exact in terms of pi
We'll subtract off the triangular region as this isn't shaded in. The area of the triangle is base*height/2 = 20*21/2 = 420/2 = 210 square inches.
So the shaded region is therefore 210.25pi - 210 square inches
This approximates to 210.25*3.14 - 210 = 450.185 when using the approximation pi = 3.14; use more decimal digits of pi to get a more accurate value.

1- The acceleration of a particle is defined by the relation a = 6 ft/s 2. Knowing
that s =-32 ft when t = 0 and v= -6 ft/s when t = 2 s, determine the velocity, the
position, and the total distance traveled when t = 5 s.
help fast
Answer:
The initial velocity of the particle is
v' = -6 - 6.2 = -18 ft/s
at t = 5s, the velocity is v = -18 + 6.5 = 12 ft/s
the position is
[tex]x = - 32 - 18 \times 5 + \frac{1}{2} \times 6 \times 5 {}^{2} = - 47 \: ft[/tex]
the total distance traveled is
[tex]s = | \frac{12 {}^{2} - 18 {}^{2} }{2 \times 6} | = 15 \: ft[/tex]
