Correct question is;
Which of these expressions is equivalent to log (9^2)?
Answer:
D: 2•log 9
Step-by-step explanation:
From log rules, we know that;
log(a^n) = n•log(a)
Applying that rule to this question, we can simplify log (9^2) as;
log (9^2) = 2•log 9
Looking at the options, the correct one is Option D
Angle P and angle Q make a
90° angle.
Angle P = 62°
Angle Q = 4x
What is the value of x?
Hope this helps
Substitute the values of angles P and Q in an equation that equals 90 degrees
62° + 4x = 90°
Then isolate the variable by first subtracting 62 from both sides
62 + 4x = 90 → 4x = 28
-62 -62
Then divide both sides by 4
4x = 28 → x = 7

Answer:
x=5.12
Step-by-step explanation:
35.16= 4.44+6x
30.72=6x
5.12=x
x=5.12

Muchii unui cub are lungimea de 16cm.Care este perimetrul unei freţe a cubului? va rog rapid dau coroana
Răspuns:
64 cm
Explicație pas cu pas:
Perimetrul fiecărei margini a unui cub:
4 * lungime laterală
Lungime laterală = 16cm
Prin urmare, perimetrul va fi:
4 * 16cm
= 64cm
Find the volume of the triangular prism in the picture shown. Round your answer to the
nearest tenth. *
1: 167
2:77.3 yd
3: 77 yd²
Given:
A figure of a triangular prism.
Height of triangular base = [tex]9\dfrac{2}{3}[/tex] yd
Base of triangular base = 4 yd
Height of prism = 4 yd.
To find:
The volume of the triangular prism.
Solution:
Volume of a triangular prism is:
[tex]V=Bh[/tex] ...(i)
Where, B is the area of triangular base and h is the height of the prism.
Area of triangular base is:
[tex]B=\dfrac{1}{2}\times base\times height[/tex]
[tex]B=\dfrac{1}{2}\times 4\times 9\dfrac{2}{3}[/tex]
[tex]B=2\times \dfrac{29}{3}[/tex]
[tex]B=\dfrac{58}{3}[/tex]
Putting [tex]B=\dfrac{58}{3}[/tex] and h=4 in (i), we get
[tex]V=\dfrac{58}{3}\times 4[/tex]
[tex]V=\dfrac{232}{3}[/tex]
[tex]V=77.33...[/tex]
[tex]V\approx 77.3[/tex]
The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.
What is the area of the shape ?
Answer:
the area is C. 39
Step-by-step explanation: If you split them into there own shapes and add them at the end.
2 x 6 = 12
3 x 5 = 15
3 x 4 = 12
12 + 12 = 24
24 + 15 = 39

what is 2 x 1 1/2
Answer:
3
Step-by-step explanation:
2 times 1 is 2 and then multiply 1/2 by 2 and you'll get 1 then add those two numbers together and you will get 3. Note: The best way to do these types of things in multiplication is to split the numbers up among the decimal places so if you did 15 times 4 then an easy way to do it would be to split the 15 with 10 and 5 so then multiply the 10 by 4 and you get 40 now do the same to the 5 and you get 20 so now add those two numbers together and you get 60(This has nothing to do with the answer i just want to help make it easier for future problems such as this).

x =3 ; y=8.4
x = 3 ; y = 15
x = 6 ; y =7.5
x = 6; y =18
Answer:
The first one.
Step-by-step explanation:
solving for x:
5/2 = 7.5/x
cross multiply
2 ×7.5 =5x
x= 2×7.5/5
x= 3
solving for y:
values of the small triangle over the bigger triangle-
5/6 =7/y
cross multiply and solve for y
y= 8.4
therefore (x= 3; y= 8.4)

What happens to the inequality sign when you multiply or divide by a negative
number?
Answer:
Much like when you divide by a negative number, the sign of the inequality must flip! ... When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!

Answer:
It switches sides

The cost of chartering a bus for the great america trip was split evenly by the 20 students planning to go. The day before the trip, 10 more students decided to go. dividing the cost evenly among all 30 students brought the average cost down by $9.00 per person. What was the total cost of chartering the bus? Please answer me with an explanation
Answer:
20c= 30(c-9)
Step-by-step explanation:
The first step in solving a word problem is always to organize the information you have, and put it into equations to solve.
Let c be the cost per student originally.
The cost of the bus has not changed, so the cost/student * the number of students has not changed:
An amusement park sold an average of 280 tickets in 4 hours. If this rate continues, how many tickets will they sell in 7 hours? *
280 tickets per 4 hours
We need to find out how many tickets they made per hour.
So: 280/40
=70 tickets
70 tickets per hour
We then need to find how many ticket they made in 7 hours.So: 70 x 7
=490 tickets
Answer:
490
Divide 280 by 4 to get average of 70 tickets an hour.
Multiple 70 X 7= 490
