One number is 5 less than twice a number.if the sum of two numbers is 76 what is the smaller number ?
Answer:
the smaller number is 27.
Step-by-step explanation:
set two numbers are a and b
one number is less that twice of a number:
let's say a is 5 less than twice of b
so we have : a=2b-5
sum of the two numbers is 76: we have a+b=76
then we set up the system of equation[tex]\left \{ {{a=2b-5} \atop {a+b=76}} \right.[/tex]
substitude a = 2b - 5 into the second equation
we have,
2b - 5 + b = 76
3b - 5 = 76
3b = 81
b = 27
Since a + b = 76 so a = 49
Joe is finding the length of a rectangular prism. The volume of the prism is 204 ft3. The width is 3.5 ft, and the height is 5 ft. His work is shown below.

the sum of 12 times a number, n, and 4 is no more than 190. What are all the possible values of the number?
Answer:
{n:n≤15.5}
Step-by-step explanation:
√First derive the inequality from interpreting the statement,thus 12n+4≤190
√Second, solve the derived inequality ( ie.make n the subject)
√Finally, you'll arrive at the answer as n≤15.5
Therefore the possible values of the variable n is all numbers less than or equal to 15.5
PROOF
For n greater than 15.5
Let's take n to be 20
Therefore from the derived inequality
12n+4≤190
12(20)+4 = 240
Here,240 is greater than 190
Since for n≥15.5 will not satisfy the inequality n≠all numbers more than 15.5

if the perimeter of the blanket has to be at least 280 inches is there egnough room for all three of them to cuddle up under the blanket? ( she’s talking about her dogs)
Answer:
hope it helps
Step-by-step explanation:
angle < EDG = 90°
5x + 4x = 90
9x = 90
x = 90/9
x = 10°
which means
5x = 50°
4x = 40°
---------------------------
sice EF and DG are parallel lines
EHD = 40°
DHG is 90°
then HGD = 50°
-----------------------------------------
ED = 64 x2 (2 sides) = 128 inches
DG = 84 x2 (2 sides) = 168 inches
total perimeter = 128 + 168 = 296 inches
and yes. theres enough room for all 3 to cuddle
Dalco Manufacturing estimates that its weekly profit, P, in hundreds of dollars, can be approximated by the
formula P = -4x² + 8x + 3, where x is the number of units produced per week, in thousands.
How many units should the company produce per week to earn the maximum profit?
Find the maximum weekly profit.
a.
b.
P = -2x^2 + 8x + 2
for maximum P, dP/dx = 0
dP/dx = -4x + 8 = 0
4x = 8
x = 2
The company should produce 2,000 units per week to earn maximum profit.
Maximum profit = -2(2)^2 + 8(2) + 2 = -8 + 16 + 2 = 10
Therefore, the maximum weekly profit is $1,000.

Steven noticed that there were 72 lights on and 78 lights turned off. Enter the percent of the lights turned on.
The lights which were on was 48%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Given that there were 72 lights on, and 78 lights turned off.
We need to find the percent of the lights turned on.
So, percentage of something =
= number of thing / total number of the thing x 100%
Here, the number of thing = light on = 72
Total = 72 + 78 = 150
So, the percent of light on = 72 / 150 x 100% = 0.48 x 100%
= 48%
Hence the lights which were on was 48%.

9514 1404 393
Explanation:
It is often useful to put everything in terms of sine and cosine.
sin(x)·(tan(x) +cot(x))
= sin(x)·(sin(x)/cos(x) + cos(x)/sin(x))
= sin(x)²/cos(x) +cos(x) . . . . . . use the distributive property*
= (sin(x)² +cos(x)²)/cos(x) . . . . . combine terms over a common denominator
= 1/cos(x)
= sec(x)

* The expression inside parentheses could have been combined to ...
(sin(x)² +cos(x)²)/(sin(x)·cos(x))
Then the sin/sin factors cancel, leaving the expression on line 4.

Solve by using substitution
8x - 10y = 4
x = 8
Answer:
y= 6
Step-by-step explanation:
First you substitute in the 8 for x. you then multiply 8 times 8 which equals 64. you subtract 64 from 4 and 64, since it would be the opposite of addition. you would then take the -10y=-60, and you would divide by negative 10 to get y by itself. since negative 60 divided by negative 10 is a positive 6, your answer would be y equals 6.
