Answers
Answer:
Option A
Step-by-step explanation:
By applying Pythagoras theorem in ΔABC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
AC² = AB² + BC²
AC² = 6² + 5²
AC = [tex]\sqrt{61}[/tex]
Similarly, by applying Pythagoras theorem in ΔACD,
AD² = AC² + CD²
(10)² = [tex](\sqrt{61})^2[/tex] + x²
x² = 100- 61
x² = 39
x = √(39)
Option A will be the answer.

A= 120 because B and A are vertical angles
Y= 22° because 120 +38= 158 and 180-158 = 22°
Answer:
a = 120
b = 120
y = 22
a and b and vertical angles
Step-by-step explanation:
angles A and B are vertical angles so they're equal.
you can find angle b because all the angles in a triangle add up to 180
19 + 41 + B = 180
b = 180 - 19 - 41
b = 120
and since theyre equal, that means
a = 120 as well.
since you know a = 120 you can find y.
120 + 38 + y = 180
y = 180 - 120 - 38
y = 22
The ratio of girls to boys is 12 girls to 20 boys.

There are
boys.
Next Question
Answers
Answer:
5
Step-by-step explanation:
ratio = 12:20
12/4 = 3
so we do
20/4 = 5
there are 5 boys
Another way, we can write it as a fraction
12/20 = 3/x
12x = 60
x = 5
Answer:
5 boys
Step-by-step explanation:
Write it like this:
3/X=12/20
Then, cross multiply.
3*20=60
X*12=12X
12X=60
Divide both sides by 12
60/12=5
X=5
The unknown number is 5
If there are 3 girls, then there are 5 boys.

Bella can run a mile in 9.54 minutes. Linda can run a mile in 8.22 minutes. How much faster can Linda run than Bella? Justify your reasoning.
Answers
Answer:1.16 times
Step-by-step explanation:
Given
Bella can run a mile in 9.54 minutes
Linda can run a mile in 8.22 minutes
We know, [tex]\text{distance=speed}\times\text{ time}[/tex]
Speed of Bella, for running a mile is
[tex]\Rightarrow v_b=\dfrac{1}{\frac{9.54}{60}}=\dfrac{60}{9.54}\\\\\Rightarrow v_b=6.29\ mph[/tex]
Speed of Linda, for running a mile is
[tex]\Rightarrow v_l=\dfrac{1}{\frac{8.22}{60}}=\dfrac{60}{8.22}\\\\\Rightarrow v_l=7.29\ mph[/tex]
So, Linda is faster than Bella, as her speed is more compared to Linda.
Linda is [tex]\frac{9.54}{8.22}=1.16[/tex] times faster than bella

Rebecca has been planting young trees in her garden. The maple tree that is 10 centimeters tall
is growing 2 centimeters per month, whereas the oak tree that is 15 centimeters tall is
growing 1 centimeter per month. In a few months, the two trees will be the same height. How
many months will this take and what will that height be?
Answers
Answer:
It will take 5 months and that height will be 20cm.
Step-by-step explanation:
Let the height of the tree be h cm and the number of months be m.
Maple tree
Initial height= 10cm
Total height= 10cm +2(number of months)
h= 2m +10 -----(1)
Oak tree
Initial height= 15cm
Total height= 15cm +1(number of months)
h= m +15 -----(2)
When the height of the two trees are the same,
2m +10= m +15
Solve for m:
2m -m= 15 -10
m= 5
Substitute m=5 into either equation 1 or 2 to obtain the height.
When m=5,
h= 5 +15
h= 20
