Step-by-step explanation:
because of order if operations.
Answer:
B
Step-by-step explanation:
The rule of PEMDAS states to start from parenthesis. To get your correct answer, you would need to prioritize what comes first going left to right.
If you were to select A, (/5) would be prioritized. D. Has the order placed in correctly, as well as C.
Determine the maximum or minimum value of the quadratic function from its equation.
Answer:
Below in bold.
Step-by-step explanation:
y = 4(x + 2)^2 + 4
As the coefficient of x^2 is positive it will have a minimum value.
The minimum value is the last term = 4.
Find the value of two numbers if their sum is 170 and their difference is 144.
Answer:
The two numbers are 157 and 13
Step-by-step explanation:
Let x and y be the two numbers
x+y = 170
x-y =144
Add the two equations together
x+y = 170
x-y =144
-------------------
2x= 314
Divide by 2
2x/2 = 314/2
x =157
Now find y
x+y = 170
157+y = 170
y = 170-157
y =13

Answer:
The value of x = 20
Step-by-step explanation:
Given:
∠BOC = 3x - 15
∠COD = 2x + 5
Find:
The value of x
Computation:
⇔ ∠BOC + ∠COD = 90
⇔ 3x - 15 + 2x + 5 = 90
⇔ 5x - 10 = 900
⇔ 5x = 90 + 10
⇔ 5x = 100
⇔ x = 100 / 5
⇔ x = 20
The value of x = 20

What is the volume of this. Pyramid
720 cm2
1080cm2
1440 cm2
2160 cm2
Answer:
Option (1)
Step-by-step explanation:
To calculate the volume of the given pyramid,
Formula to be used,
Volume = [tex]\frac{1}{3}(\text{Area of the triangular base)}(\text{Height})[/tex]
Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(9)(15)[/tex]
= 67.5 cm²
Now volume of the pyramid = [tex]\frac{1}{3}(67.5)(32)[/tex]
= 720 cm³
Therefore, Option (1) will be the correct option.

1/4, 1/2, 1, 2 converging or diverging
Answer:
diverging
Step-by-step explanation:
A regular way to know if a series is converging or diverging, is to check is as the number of terms increase, the value of such terms also increase.
So, if for example, we have:
[tex]A_n > A_{n-1}[/tex]
We know that the series will not converge, because eventually the terms will be very large, and the series will diverge.
In this case we have the series:
1/4, 1/2, 1, 2
So each term is two times the previous one, thus, the n-th term will be larger than the n-th minus one term, so we can conclude that this series diverges.

Mike has 25 cards and Ali has 55. How many cards must Mike give Ali so that Ali will have 4 times as many cards as Mike?
Answer:
9 cards
Step-by-step explanation:
Mike will have to give Ali 9 cards
Mike 25 -9 = 16
Ali 55 + 9 = 64
you can see that Ali 4 times as many cards as mike
64 : 16
4 : 1
Can I get help with these questions 17,18,20,22,23,27,30 &31
Only reply if you are seriously going to help me please
No spam I would really appreciate it
Answer:
17) just take the root of 100. the text says its square(d).
10m
And checking it gives 10m * 10m = 100m²
18) you need to learn some square numbers to ace this topic. it isn't that complicated, just multiply natural numbers with themselves
like
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
Now we can see that a) sqrt(55) lies between 7 and 8, and that its value is somewhere in between
7 < a < 8
(ignoring the negative solution to the root oc)
try b, c and d yourself. if you struggle, leave a comment.
I got a problem finding exercises 19 to 21, seriously....
22) well...
a * b = 18ft²
6ft * 3ft seems just right. pure guesswork here, seems to be to easy with these numbers.
but we can also write it as a system of two functions
a * b = 18ft²
a = 2b
and then solve it by substituting a in line one with 2b, since a is 2b this is allowed.
2b * b = 18
2 b² = 18
b² = 9
b = 3
(we ignore -3 as a solution bc negative length makes no sense)
plugging that b into line two of the system gives
a = 2 * 3
a = 6
27) rationale can we written as a ratio (a fration)
it almost sounds too simply
rationals are either the root of square numbers, bc they can be solved cleanly, or they got a repeating pattern after the point.
b and c apply to these rules, a and d not
30) lol, I just figured out where the missing exercises are hidden XD
31) just add up the three rectangles (easy part) with the two triangles top and bottom each triangle is just 12m * 16m / 2 (bc it's a triangle, not a rectangle). since you got two triangles you just multiply by two (it's like ignoring the decision. also, the two triangles together would indeed make just a n9ce rectangle).
if you really need the values, leave a comment, but that will not help you in any test.
you can also post your solutions and I'll check them.
32) area of the circle times two
plus area of a rectangle wrapped around the cylinder.
circle are is pi*r² -> pi * (28 in)²
(remember to double for two circles)
rectangle is the circumference of the circle (pi * 28in) times the height of the cylinder
like in 31), feel free two post your results or ask for values if you really struggle to grasp the pattern here.
hope you have a great day and that you understand some more of the topic. you can ace it :)
Two angles are complementary. One angle is
fifteen more than twice the other angle.
What is the measure of each angle?
Step-by-step explanation:
Hey there!
Let "x°" be the first angle.
According to the question; the another angle is (2x+15)°. {since the condition of the question is fifteen more twice of the other angle }
Also, we know that complementary angles sum is 90°.
Then;
x° + 2x° + 15° = 90°
3x ° = 90°-15°
3x = 75°
x = 75°/3
Therefore, the angles are 25° and 65°.
Hope it helps!
Find the value of X and TQ
ok I don't know go to school or sum
what is the measurement of SRT
A: 101 degrees
B: 79 degrees
C: 99 degrees
D: 69 degrees
Answer:
79°
Step-by-step explanation:
Remember, the sum of all the angles in a triangle is 180
So 180-RST-RTS=180-53-48=79

I believe it is 60 degrees
Step-by-step explanation:
90 degrees plus 30 is 120 then plus x will be 180 so 180 - 120 is 60

If m>BFC = 8x+13 and m
Answer:
12x - 73
Step-by-step explanation:
DFE + CFD = 12x + 7
DFE + 90 = 12x + 7
DFE = 12x + 7 - 90
DFE = 12x - 83
therefore
DFE = AFB ( vertically opposite angles are equal)
AFB = 12x - 83

Answer:
D - T-H is negative
Step-by-step explanation:
So lets go through what we know:
M is on the left side of 0, so M is negative.
A is also one the left side of 0, so A is negative.
T is on the right side of 0, so T is postive
H is also on the right side of 0, so H is postive
Lets go through each answer and see if it is accurate or not:
The sum of M and H is postive.
With what we know, M is negative and H is postive.
Looking at the graph, we can see that M is farther to the left than H is to the right.
So this means that M is a larger negative than H is postive, meaning when we add them together, the answer will be negative, not postive.
Next we have the answer to A divided by H is negative
We know A is negative, and M also negative
Remember, a negative divided or multiplied by a negative is postive.
This is not what our answer states, as it says it should be negative.
So next off, we have the product of H and A is postive.
Product means multipication.
A is negative and H is postive
Since it is multipication, and we know a negative and postive make another negative, this would make it incorrect
The answer states it must be postive, but this is negative.
Finally we have the answer as T-H is negative.
We see that T is postive, and H is postive.
T is less than H is, so when you subtract H from T, you would get a negative.
So D is the answer
Hope this helps!

Joan is buying airline tickets for her family. Each airline ticket costs $232 with a baggage fee of $13. The airline
charges a booking fee of $45 for the entire set of tickets. Joan spent a total of $1,515. If x represents the number of
tickets, which equation can be used to find the value of x?
O 245+45x = 1,515
O 232x+45x - 1,515
O 232x+45= 1,515
452455
Answer:
232x + 45 = 1,515
Step-by-step explanation:
45 is a one time fee for book several tickets at one. 232 is the cost of each ticket and 232 get x because we dont know how many family members Joan bought tickets for.

The picture of the question is attached.
Answer:
x = 90°
Step-by-step explanation:
Using the identity
cos²x = 1 - sin²x
Given
cos²x - sin x + 1 = 0
1 - sin²x - sin x + 1 = 0
- sin²x - sin x + 2 = 0 ← quadratic equation in sin x ( multiply through by - 1 )
sin²x + sin x - 2 = 0 ← in standard form
(sinx + 2)(sinx - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
sinx + 2 = 0 ⇒ sinx = - 2 ← has no solution as - 1 ≤ x ≤ 1
sinx - 1 = 0 ⇒ sinx = 1 ⇒ x = 90°
solution is x = 90°

int steps = 4;
for (int i = 0; i < steps; i++) { }
this part is psuedocode:
print(i) blocks
there will be 36 squared.
each new step adds one more than the last step added.
f(1) = 1
f(2) = 3 = 1+2
f(3) = 6 = 1+2+3
f(4) = 10 = 1+2+3+4
the pattern is now clear hopefully
f(8) = 1+2+3+4+5+6+7+8 = 1+8 + 2+7 + 3+6 + 4+5 = 9+9+9+9 = 9*4 = 36
