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.
I hope it helps you!
solve for y
3x+1/5y=7
Answer:
y = -15x + 35
Step-by-step explanation:
3x + 1/5y = 7
1/5y = -3x + 7
y = 5( -3x + 7)
y = -15x + 35
Im supposed to find angles for these, and I don't know on how to do that
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°

Complete question :
Angela makes a pillow in the shape of a wedge to use for watching TV. The pillow is filled with 0.35 m3 of fluffy material, with base 0.5 m and height 1m
What is the length of the pillow?
Answer:
1.4 m
Step-by-step explanation:
The volume of wedge is given by:
V = Area of triangle * length
Area of triangle = 1/2 * base * height
Volume of wedge = 1/2 * base * height * length
Volume of wedge = 0.35m³
0.35 = 0.5 * 0.5 * 1 * length
0.35 = 0.25 * length
Length = 0.35 / 0.25
Length = 1.4 m
Answer:
1.4

Problem 3
Answer: x = 47Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.
==================================================
Problem 4
Answer: x = 32Explanation:
Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.
For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74
Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32
==================================================
Problem 5
Answer: x = 58Explanation:
Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.
For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58
Answer:
3. x = 47
4. x = 32
5. x = 58
Step-by-step explanation:
In a survey of U.S. Adults, 16% say they have had someone take over their email accounts without their permission. You randomly select 250 U.S. Adults and asked them whether they have had someone take over their email accounts without their permission. Find the probability that the number of U.S. Adults who say they have had someone take over their email accounts without their permission is : a. At most 40 b. Less than 45 c. Exactly 48
Answer:
a. At most 40
Step-by-step explanation:
If we take the survey that was done as a basis then we would use the 16% that was obtained as the number of overall US adults that have had their accounts used without their permission. Assuming that the 250 selected individuals were selected at random and without bias then those 250 would also be representative of the entire population. Therefore, we would simply need to multiply the number of selected individuals by the percentage in decimal form.
16 / 100 = 0.16
250 * 0.16 = 40
Finally, we can see that roughly 40 individuals would have had their email used without permission.

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.

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.
