Answer:
81
Step-by-step explanation:
Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]
[tex]\frac{4}{9}[/tex] = [tex]\frac{396}{x}[/tex] so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.
You could set up another proportion 1/11 = x/891
If there are 396 female students, there are 81 teachers.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
First, Set up a proportion to find how many total students there are
[notice how females are on top and totals are on the bottom of the ratios]
So, 4/9 = 396 / x
then, cross multiply
4x = 396(9)
so x = 891,
if there are a total of 891 students and we need 1 teacher per 11 students then take 891/11.
Thus, you need 81 teachers.
Also, we could set up another proportion 1/11 = x/891
Hence, If there are 396 female students, there are 81 teachers.

in triangle VUT.
Which statements are true regarding the transformation?
Select two options.
SRE
OSQ corresponds to VU.
V
O ZR corresponds to ZU.
UV corresponds to RS.
OZS corresponds to ZT.
OQS corresponds to RS.
Sign out
Answer:
UV corresponds to RS.
[tex]\angle R[/tex] corresponds to [tex]\angle U[/tex]
Step-by-step explanation:
Given
[tex]\triangle SRQ[/tex] and [tex]\triangle VUT[/tex]
Transformation: Rigid
Required
Determine the true options
When a rigid transformation occurs from SRQ to VUT, the following are the corresponding sides:
SR to VU, SQ to VT, RQ to UT
And the corresponding angles are:
<S to <V, <R to <U and <Q to <T
From the corresponding sides above, we have:
SR to VU
Rewrite:
RS to UV
Hence: (c) is correct
From the corresponding angles above, we have:
[tex]\angle R[/tex] to [tex]\angle U[/tex]
Hence:
(b) is correct
The endpoints of line segment. CD are C(-4,7) and D(0,-3). Find the midpoint of
line segment CD.
Given:
The endpoints of line segment CD are C(-4,7) and D(0,-3).
To find:
The midpoint of CD.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the midpoint formula, the midpoint of CD is
[tex]Midpoint=\left(\dfrac{-4+0}{2},\dfrac{7-3}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{4}{2}\right)[/tex]
[tex]Midpoint=\left(-2,2\right)[/tex]
Therefore, the midpoint of the line segment CD is (-2,2).
Molly bought 10 bags of the same dog food. She had a coupon for $5. She sprang a total of$65. How much money was each of bags dog food?
Answer:
$7
Step-by-step explanation:
if she bought 10 bags and had $5 off and she spent $65 it would technically its $70 ÷ 10 = $7 per bag.
Each bag of dog food cost $7.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
Molly bought 10 bags of the same dog food.
She had a coupon for $5.
and, the amount without coupon is $65.
Then, the total amount is
= 65 + 5
= $70
So, the price per bag is
= 70/ 10
= $7

Answer:
b. x=2
Step-by-step explanation:
The axis of symmetry of a parabola gives us a line of symmetry where the parabola appears the same but flipped on either side. It passes through the parabola's vertex, or the minimum/maximum point of the parabola. Here, we can see that the parabola's minimum point occurs when x=2. Therefore, its axis of symmetry is x=2.

HELP??? What is the equation of the line in y=mx+b format?
Answer:
y = 1/2x - 1Step-by-step explanation:
To find the slope, you need to find the y-intercept first (or the place the line crosses over the y-line). After you've found the y-intercept (-1), you need to find the next point that the line crosses. This line has a positive slope, so you'll want to look for the next point towards the right. The next point was 1 up and 2 over.
Answer:
y = 2/5x - 1
Step-by-step explanation:
There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.

the lenght of a rectangular field is twice its breadth. A girl jogged around it 4 times and covered a distance of 4.5 km. what is the length of the field
Step-by-step explanation:
4.5÷4= 1.125
so each time she goes around the rectangle she's covering 1.125 km and we seed the length is twice the breadth x+2x=1.125
so 1.125 / 3 to give x which is the breadth=0.375 x 2 is equal to 0.75 km or 750 m this is the length of the field
Step-by-step explanation:
The length of a rectangular field is twice it's breadth. A girl jogged around it 4 times and covered a distance of 4.5 km. What is the length of the field?
The distance cover in 4 laps is 4.5 km, So one lap is 4.5/4 = 1.125 km.
Let the breadth of the field be B so the length will be L or 2B.
The perimeter of the field is 2L+2B or 4B+2B = 6B = 1.125, so B = 1.125/6 = 0.1875 km and the length is 2*0.1875 = 0.375 km.
Check: perimeter = 2*0.375 + 2*0.1875 = 1.125 km and 4 laps covers 4*1.125 = 4.5 km. correct.
The field is 375 m long.
You pick a card at random. 4 5 6 7 What is P(less than 7)? Write your answer as a fraction or whole number.
Answer:
3/4 is less than 7.
Step-by-step explanation:
There are 4 numbers but there are only 3 less than 7.
The probability P(less than 7) is 3/4.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
For the given situation,
The cards are numbered as s = {4,5,6,7}
⇒[tex]n(s)=4[/tex]
The event is probability of picking the cards less than 7
Cards less than [tex]7[/tex] , [tex]e=4,5,6[/tex]
⇒[tex]n(e)=3[/tex]
Probability of picking the card is given by [tex]p(e)=\frac{n(e)}{n(s)}[/tex]
On substituting the values,
⇒[tex]p(less than 7)=\frac{3}{4}[/tex]
Thus the probability P(less than 7) is 3/4.

A farmer harvests 850kg of parsnips. 30% go to the local market and 50% go to a local supermarket. What mass of parsnips are left?
answer is 170
---------------------------
50% of 850 = 425
30% of 850 = 255
425 + 255 = 680
850 - 680 = 170
There are 170 kg mass of parsnips left after distributing to the local market and local supermarket.
To calculate the mass of parsnips left after distributing them to the local market and the local supermarket, we need to subtract the quantities allocated to these places from the total harvest.
The farmer harvested 850 kg of parsnips.
30% of the harvest goes to the local market, which is (30/100) * 850 kg = 0.3 * 850 kg = 255 kg.
50% of the harvest goes to the local supermarket, which is (50/100) * 850 kg = 0.5 * 850 kg = 425 kg.
To find the mass of parsnips left, we subtract the quantities allocated to the market and supermarket from the total harvest:
Total harvest - (Quantity for market + Quantity for supermarket)
= 850 kg - (255 kg + 425 kg)
= 850 kg - 680 kg
= 170 kg.
Therefore, there are 170 kg of parsnips left after distributing to the local market and local supermarket.
