ill mark brainlist plss help
he is going to need 37.5 ounces I guess
solve it...........!!!!
Answer:
I think it is correct and is 1 and 2
Step-by-step explanation:
5×4^(x+1)-16^x=64
0=64+16^x-5×4¹×4^x
0=(4^x)²-2×4^x×10+10²-10²+64
0=(4^x-10)²-36
(4^x-10)²=36
4^x-10=√36
4^x=+-6+10
when positive
4^x=4²
:.x=2
when negative
4^x=4
:.x=1
:.x=1,2 answer.

Answer:
110
Step-by-step explanation:
They are equal to each other.
23x-5= 21x +5
2x = 10
x = 5
21(5) +5 = 110°
23(5) -5 = 110°
So it works. Angles are 110°

9514 1404 393
Answer:
$503.85
Step-by-step explanation:
The amortization formula can help with this.
A = P(r/12)/(1 -(1 +r/12)^(-n))
where P is the loan value, A is the monthly payment, r is the annual interest rate, and n is the number of monthly payments.
We want to find P. All of the other values are given.
P = A(1 -(1 +r/12)^-n)/(r/12)
P = 32.48(1 -1.012667^-18)/(0.012667) = 31.48·16.0054
P ≈ 503.85
The equivalent cash price is about $503.85.
Find the area of the base of a box of height 4cm and lateral surface area 120cm.sq if its length is twice its breadth.
Answer:
The area of the base of a box is 1800 cm².
Step-by-step explanation:
We have:
H: is the height = 4 cm
[tex]A_{l}[/tex]: is the lateral surface area = 120 cm
L = 2B
We can find the breadth of the base by using the lateral surface area and the height:
[tex] A_{l} = H*B [/tex]
[tex] B = \frac{A}{H} = \frac{120 cm}{4 cm} = 30 cm [/tex]
Now, if the length is twice its breadth we have:
[tex] L = 2B = 2*30 cm = 60 cm [/tex]
Hence, the area of the base is:
[tex] A_{b} = B*L = 60 cm*30 cm = 1800 cm^{2} [/tex]
Therefore, the area of the base of a box is 1800 cm².
