Answer:
40
Step-by-step explanation:
a+b=c
a=girls
b= boys
c= total
the statement tell us:
4/5 of a class is girls:
a=(4/5)*c
boys=b=8
c=a+b
so we have:
c=(4/5)*c + 8
c-(4/5)*c=8
(5c-4c)/5 = 8
c/5=8
c=8*5
c=40
total=40
Answer:
The meal must cost less than or equal to 19.92
Step-by-step explanation:
Let x be the cost of the mean
First find the tax
tax = x* 5.5%
=.055x
Then find the tip
tip = x * 20%
tip = .20x
Add the total cost together
total cost = meal + tax + tip
=x + .055x + .20x
=1.255x
This must be less than or equal to 25
1.255x ≤ 25
Divide each side by 1.255
1.255x/1.255 ≤ 25/1.255
x ≤ 19.92
Answer:
i can put 4 pens in 3 groups
Step-by-step explanation:
4 times 3 = 12
Previous balance = $291.96
Payments/credits = $45.00
Unpaid balance = $ 291.96 - $45.00 = $ 246.96
Monthly Interest rate = 1.5 %
Finance charge = 1.5 % of $ 246.96= $3.70
Total balance to be paid when Finance charge is included = $ 246.96 + $3.70= $ 250.66
New purchases = $103.98
New balance = $ 250.66 + $103.98 = $ 354.64
Answer: A) segment MN ≡ segment QPIf two triangles are congruent, they have corresponding sides and corresponding angles congruent.
In order to find which are the corresponding sides, you need to be careful about the order of the letters, and therefore of the vertices (see picture attached).
From the congruency, we can say:
∠M ≡ ∠P
∠N ≡ ∠Q (statement B)
∠O ≡ ∠R (statement D)
MN ≡ PQ
NO ≡ QR (statement C)
OM ≡ RP
Hence, the only statement which is not true is <span>
A) segment MN ≡ segment QP.</span>
