Answer:
7 inches
Step-by-step explanation:
First you have to find the average height of each class.
4th Grade:
56, 47, 54, 51, 53, 58, 48, 54, 46, 53
Then you have add it all up and divide it by how many students there are.
56 + 47 + 54 + 51 + 53 + 58 + 48 + 54 + 46 + 53 = 520
520 ➗10= 52
Same process for the 7th Grade.
You end up getting 52 and 59. You then Subtract it to get the answer to the question.
52 - 59= 7 inches

4x^2 B
-4x^2 A
1/4x^2 D
-1/4x^2 C
Step-by-step explanation:
1. Look at the concavity
up or down = negative or positive.
2. number before the x value
if N < 1, it will be wider. if N > 1, it will be thinner.
3. the two most right graphs would be -1/4x^2 and 1/4x^2
the one that is concave down is the - and the concave up is +

The mean distance that and Tina drove was 153 kilometers.If Ben drove 24 kilometers more than Tina,what was the distance that Tani drove?
Answer:
141 km
Step-by-step explanation:
Given data
Mean distance= 153km
Let Tina dirve=x km
Ben= x+ 24
Number of participants= 2
Hence,
Mean= total distance/number of participants
153= x+24+x/2
cross multiply
153*2= x+24+x
306 =2x+24
306-24= 2x
282=2x
Divide both sides by 2
x= 282/2
x= 141km
Hence Tina drove 141 km

b)[tex](x+1)(3x+2)[/tex]
Step-by-step explanation:
write additive and multiplicative inverse of19/-6 and-2/3
Additive inverse of 19/-6 is 19/6
Additive inverse of -2/3 is 2/3
Multiplicative inverse of 19/-6 is -6/19
Multiplicative inverse of -2/3 is 3/-2 (also written as -3/2)
Step-by-step explanation:
(a) The additive inverse of a number is that number that when added to it gives 0.
For example, the additive inverse of x is -x.
This is because adding -x to x gives 0. i.e
x + (-x) = 0
In other words, the additive inverse of a number is the negative of that number.
Given:
(i) 19/-6
The additive inverse of 19/-6 is the negative of 19/-6 which is -(19/-6).
-(19/-6) then gives 19/6
Therefore, the additive inverse of 19/-6 is 19/6
(ii) -2/3
The additive inverse of -2/3 is the negative of -2/3 which is -(-2/3).
-(-2/3) then gives 2/3
Therefore, the additive inverse of -2/3 is 2/3
(b) The multiplicative inverse of a number is that number that when multiplied by it gives 1.
For example, the multiplicative inverse of y is 1/y.
This is because multiplying y by 1/y gives 1. i.e
y x (1/y) = 1
In other words, the multiplicative inverse of a number is the reciprocal of that number.
Given:
(i) 19/-6
The multiplicative inverse of 19/-6 is the reciprocal of 19/-6 which is 1/(19/-6).
1 / (19/-6) then gives -6/19
This is found by just swapping the numerator(19) and the denominator(-6)
Therefore, the multiplicative inverse of 19/-6 is -6/19
(ii) -2/3
The multiplicative inverse of -2/3 is the reciprocal of -2/3 which is 1/(-2/3).
1 / ( -2/3) then gives 3/-2
This is found by just swapping the numerator(-2) and the denominator(3)
Therefore, the multiplicative inverse of -2/3 is 3/-2 (also written as -3/2).
The ratio of cattle to horses on the ranch was 12 to 3. The combined number of cattle and horses was 960. How many horses are on the ranch?
Answer: There are 192 horses in the ranch
Step-by-step explanation:
The combined number of cattle and horses = 960.
Ratio of cattle to horses =12 :3
Total ratio =12+3=15
Number of horses on the ranch = ratio of horse / Total ratio x total number of horses and cattle
3/15 x 960 = 192
Therefore there are 192 horses in the ranch

Answer:
[tex]\approx 11.2\:\mathrm{in}[/tex]
Step-by-step explanation:
The swing of the tip of pendulum is creating an arc. The question is actually asking for the length of this arc. The length of an arc is given by [tex]2r\pi\cdot \frac{\theta}{360}[/tex], where [tex]r[/tex] is the radius of the circle and [tex]\theta[/tex] is the angle of the arc.
In this problem, we're given:
[tex]\theta = 40^{\circ},\\r=16[/tex]
Substituting given values, we get:
[tex]2\cdot 16\cdot \pi \cdot \frac{40}{360}=32\pi\cdot \frac{1}{9}\approx \boxed{11.2\:\mathrm{in}}[/tex]
