Answer:
24 girls
Step-by-step explanation:
Ratio girls to boys: 4:7
The ratio involved a total of 11 people.
There are 66 students in fifth grade, and there is a 4:7 girl to boy ratio.
66/11 = 6
<u>Girls: 6 x 4 = 24</u>
Boys: 6 x 7 = 42
The total of girls to boys should be equal to 66.
24+42=66
Answer:
Step-by-step explanation:
multiply numerator and denominator by k² to eliminate fractions
= 
← factor numerator and denominator
------------------------------
k² - 25 ← is a difference of squares
= (k - 5)(k + 5)
k² - 7k + 10
= (k - 5)(k - 2)
------------------------------
= 
← cancel (x - 5) on numerator / denominator
=
Answer:
32
Step-by-step explanation:
As there are two ways to answer each question wither true or false and 5 questions to be attempted.
So the possible outcomes will be:
Possible outcomes = ways to answer ^ total questions
= 2 ^ 5
= 32
Answer:
1,Let us suppose that the height of the ladder is h and the horizontal distance of the ladder from the wall is d, then we use these two important trigonometric functions; the sine and the cosine.
h = sin 78 * 8 m and d = cos 78 * 8m where sin 78 = 0.9781 and cos 78 = 0.2079
With the given values, I expect you to do the two multiplications yourself. You will obtain a near to 8 m answer for the height h and a near to 1.7 m answer for the distance d.
2, The ship is 15 km from the port.
3,30m The ship must travel 15.6km 10 km 8. A rectangular field is 40 m long and 30 m wide. Carl walks from one corner of the field to the opposite corner along the edge of the field. Jade walks across the field diagonally to arrive at the same corner. Tip How much shorter is Jade's shortcut? Show your work. Sketch a diagram Carl-40m ade - b?= C² first. 40m. Jade = a't 62=(3 30' + 402 c 900 + 1,600 e? C² =2,5 U0 %3D C=/2500 C=50 10m shorter. jade shortcut is 172
