Evaluate 15 − 4 + (7 − 5)2 = __________.

Answers

Answer 1

Answer: 26? right? cause 15 - 4 is 11, 7 - 5 is 2, 11 + 2 is 13, and 13 x 2 is 26

Answer 2

Answer: 15-4=11 plus
(7-5)= 2
if is times 2 is 32
if is plus 2 is 15
if is minus 2 is 11
and if is divided by 2 is 6.5
(I'm saying all that because you didn't put any symbol beside the number 2)

C. 420

D. 564

Answers

The answer is D. 564
When you put all the numbers in order from least to greatest and find the median which is between 420 and 434, you can then find your upper quartile which would be between 540 and 588 making it D

An object is thrown upward at a speed of 121 feet per second by a machine from a height of 8 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t^2+121 t+8 When will the height be 17 feet?

When will the object reach the ground?

Answers

17=-16t^2+121t+8
16t^2-121t+9=0
this is a quadratic.
it solves to 7.487seconds and 0.075 seconds.

0=-16t^2+121t+8
16t^2-121t-8=0
this solves to 7.628 and -0.066. obviously the time cant be negative so the only real answer is 7.628 seconds

Divide 6/13 by 6/12 .

A. 9/16 B. 1/12 C. 13/12 D. 12/13

Answers

$((6)/(13))/((6)/(12))$

first simplify
$(6)/(12)$ = $(1)/(2)$

$((6)/(13))/((1)/(2))$
make bottom number equal to 1
multiply whole thing by $((2)/(1))/((2)/(1))$
(since 1/2 times 2/1=2/2=1 so bottom number will be equal to 1)

$((6)/(13))/((1)/(2))$ times $((2)/(1))/((2)/(1))$ = $((12)/(13))/((2)/(2))$ = $((12)/(13))/(1)$ = $(12)/(13)$

easy way is
a/b divided by c/d=a/b times d/c
invert and multiply

answer is 12/13

answer is D

Divide 6/13 by 6/12 .
d 12/13
1. make the fractions in decimals
2. divide the two
3. match it up

What is the intersection of plane WZVS and plane STUV?

Answers

Answer: The required intersection is the line 'VS'.

Step-by-step explanation: We are given to find the intersection of the planes WZVS and plane STUV.

We know that,

If two planes intersect each other, then their intersection is a straight line.

As shown in the given figure, the point 'V' and 'S' lie on both the planes WZVS and STUV.

So, the line joining these two points, i.e., the line VS also lie on both the planes.

Therefore, the intersection of both the planes is the line 'VS'.

Thus, the required intersection is the line 'VS'.

An easy way to find this is to look at the cross section, and see where the lines meet

the theatre charges $9 for each adult ticket and $6 for each child ticket. the theatre sold 144 tickets for the first showing of the new release. the total money collected from ticket sales for that show was $1164. write a system of equations that could be used to find the number of child tickets and the number of adult tickets sold, and solve the system algebraically.

Answers

x=number of adult tickets
y=number of child tickets
I suggest this system of equations:
x+y=144
9x+6y=1164
we can solve this system of equations by substitution method.
x=144-y

9(144-y)+6y=1164
1296-9y+6y=1164
-3y=1164-1296
-3y=-132
y=-132/-3=44

x=144-y
x=144-44=100

Answer: the theatre sold 100 adult tickets and 44 child tickets.
