=) of the 35 seventh graders polled, 1/7 of them play a sport. How many do not play a sport?
a)5 students
C)25 students
B)14 students
D)30 students
Answer:
D
Step-by-step explanation:
the number of students who plays sport are 1/7 of 35 that means that there are 35/7 students play sport so there is only 5 of 35 students play sport
so number of students thatn dont play sport are 35 - 5 = 30

7 8 9 11 11 11
can anyone help? im a lil lost
Answer:
So they just want you to solve the equation if x= -4
d(-4) = -(-4) + -4
y = 4 - 4
The solution would be 0.

Isaac and Albert spot a hot air balloon flying at a low altitude. They decide to calculate its height by standing 400 feet apart on a level surface and measuring the angle of elevation to the balloon. From
Albert, the balloon was at an angle of elevation of 62°and from Issac its was 48º. Determine the height of
the balloon above the ground to the nearest foot.
Answer:
144 feet to nearest foot.
Step-by-step explanation:
Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet
So we have 2 right angled triangles and:
tan 62 = h/x
tan 48 = h / (400- x) where h is the height of the balloon.
From the first equation x = h / tan 62 so plugging this into the second one:
tan 48 = h / ( 400 - h/tan 62)
h = 400 tan 48 - h tan 48 tan 62
h + h tan 48 tan 62 = 400 tan 48
h ( 1 + tan48 tan62) = 400 tan48
h = 400 tan 48 / (1 + tan 48 tan 62)
= 143.8 feet.

A butcher has 15 and 3/4 pounds of steaks and portions them into 7 sealed packs. How many pounds does each pack of steak weigh? *
Answer:
9/4 or 2 and 1/4 pounds
Step-by-step explanation:
Convert 15 and 3/4 into an improper fraction
15*4+3 = 63
63/4
63/4 ÷ 7
9/4
Thus, each pack weighs 9/4 pounds
Answer:
2 1/4 pounds each
Step-by-step explanation:
Convert 15 1/4 into a decimal (15.75) then divide by seven (15.75 ÷ 7 = 2.25)
and then convert 2.25 back into a fraction, 25 is 1/4 of 100 so the answer is 2 1/4

Hey There!
So when finding probabilities we want to find how many even numbers there are and divide that by the amount of numbers
we see that there are 3 even number ( 2, 16 and 8) and there are 8 numbers in total
So in one spin the probability of it landing on an even number is 3/8
Now to find the probability it will land on an even number in 120 spin we multiply 3/8 and 120
[tex]\frac{3}{8} x 120=45[/tex]
So the reasonable prediction of it landing on an even number out of 120 spins is 45

What is the explicit rule for the sequence:
11, 22, 44, 88...
Answer:
Geometric Progression is the explicit rule for the given sequence: 11, 22, 44, 88...
First term (a) = 11
Common ratio (r) = 22/11 = 44/22 = 88/44 = 2
Formula used in Geometric Progression is :---
[tex]\boxed{a_n = a {r}^{(n - 1)}}✓\\ [/tex]
where, 'n' is the required term

Step-by-step explanation:
solve for a, geometry work
Answer:
a = 45 degrees
Step-by-step explanation:
Since both angles are a, they are equal to each other
Also, we know that the right angle means it measures 90 degrees
So, (180-90)/2 = a
a = 45 degrees

solve for x
solve for x
Answer:
x = 18
Step-by-step explanation:
Total interior angle of pentagon: 540 degrees
(3x + 23) + (9x - 6) + 95 + 90 + (7x - 4) = 540
19x + 23 - 6 + 95 + 90 - 4 = 540
19x + 17 + 95 + 90 - 4 = 540
19x + 13 + 185 = 540
19x + 198 = 540
19x = 342
x = 18
Answer:
its 18
