The equation is 15*w*14 = 2730
We simply multiply length, width and height to get the volume of the rectangular block.
That equation becomes 210w = 2730 because 15*14 = 210
From here, we divide both sides by 210
You should end up with w = 13
As a check, 15*w*14 = 15*13*14 = 2730 which confirms we have the correct replacement for w.
If f(x) = 3x + 4, what is the value of f(-4)?
Answer:
-8
Step-by-step explanation:
f(x) = 3x + 4
substitute -4 in place of x
f(-4) = 3*-4 + 4
f(-4) = -12 + 4
f(-4) = -8

a) what is the difference in temperatures between 7 am to 5 pm
b) which part of the day was the temperature rising the fastest a, b, c, d, or e?
Answers:
a) The difference in temperature is 25 degrees Fahrenheit. b) The temperature was rising fastest during interval 'a'=========================================================
Explanations:
a) We subtract the y coordinates of the left and right endpoints. We get 65-40 = 25b) The fastest rising temperature will visually correspond to the steepest part of the curve. That would be region 'a'. After this interval, region b is still increasing, but not as much as the previous interval (since it's not as steep here). Then it gets less steep for region c, and d sort of flattens out as well. So during the morning hours it appears the temperature is going up the fastest.Given that y = 9 cm and 0 = 23°, work out x rounded to 1 DP.

Answer:
x ≈ 3.5 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin23° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{y}[/tex] = [tex]\frac{x}{9}[/tex] ( multiply both sides by 9 )
9 × sin23° = x , then
x ≈ 3.5 cm ( to 1 dec. place )
Which equations have the same solution as p−3=5?
Hint: There are 3 equations
3p=30
3 p is equal to 30
p+2=10
p plus 2 is equal to 10
p8=1
p over 8 is equal to 1
p+7=16
p plus 7 is equal to 16
4p=32
Answer:
p + 2 = 10
[tex]\frac{p}{8} =1[/tex]
4p = 32
Step-by-step explanation:
p - 3 = 5
p - 3 + 3 = 5 + 3
p = 8
3p = 30
3p ÷ 3 = 30 ÷ 3
p = 10
10 ≠ 8
p + 2 = 10
p + 2 - 2 = 10 - 2
p = 8
8 = 8
[tex]\frac{p}{8} =1[/tex]
[tex]8(\frac{p}{8}) =8(1)[/tex]
8 = 8
p = 8
p + 7 = 16
p + 7 - 7 = 16 - 7
p = 9
9 ≠ 8
4p = 32
4p ÷ 4 = 32 ÷ 4
p = 8
8 = 8

y⁵ - y² = y³
All together; 5x⁻¹y³
Since the answer has to be positive exponents, it would be;
[tex]\frac{5y^3}{x^1}[/tex]

amelia is going to invest in an account paying on interest rate of 6.5% compounded daily? help me plz someone
Answer:
$9,763
Step-by-step explanation:
Using the compund interest formula;
A = P(1+r)^t
A is the amount = $10,200
rate r = 6.5%= 0.065
time t = years
n = 1/365 ((daily compounding)
Substitute into the formula and get Pincipal P
10,200 = P(1+0.065(365))^5/365
10200 = P(1+23.725)^0.01369
10200 = P(24.725)^0.01369
10200 = P(1.0448)
P = 10200/1.0448
P = 9,762.6
Hence the amount invested is $9,763 to nearest dollars

Answer:x

permiter=6
area=24
Step-by-step explanation:
Answer:
x = 8, area = 364 km^2, perimeter = 80 km
Step-by-step explanation:
to start, we have to recognize that opposite sides of a rectangle are congruent.
therefore ➪
2x + 10 = 4x - 6
2x + 16 = 4x
16 = 2x
x = 8
now just plug that in and you'll find ➪
length = 26km
width = 14km
area = l * w
area = 26 * 14
area = 364 km^2
perimeter = 2(l + w)
perimeter = 2(14+26)
perimeter = 80 km

• He uses his protractor to draw a angle on one end of the line
segment.
ANSWER BOTH QUESTIONS ILL GIVE BRANLIEST AND LOTS OF POINTS .
Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.
How to solveYes, there is a different triangle Noah could draw. Since Noah has only drawn one side and one angle, he can create two different triangles using the Angle-Side-Side (A S. S) ambiguity
To find the other possible triangle, we need to calculate the angle opposite the 6 cm side. In this case, the given angle is 30°. Using the sine rule, we can find the sine of the opposite angle (let's call it θ):
sin(θ) / 6 = sin(30°) / 4
sin(θ) = (6 * sin(30°)) / 4
sin(θ) ≈ 0.5
θ ≈ 30°
Since the sum of angles in a triangle is 180°, the other angle in the triangle is:
180° - 30° - 30° = 120°
Now, we can use the sine rule again to find the length of the side opposite this new angle:
x / sin(120°) = 6 / sin(30°)
x ≈ 6 * sin(120°) / sin(30°)
x ≈ 10.39 cm
Therefore, Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.

Step-by-step explanation:
Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. After how many years will the two populations be the same?
The two populations will be the same after
years.
Answer:
3 years
Step-by-step explanation:
Let y = number of orangutans, and let x = number of years.
For each study, the population, y, after x years is:
First study:
y = 784 - 25x
Second study:
y = 817 - 36x
We set the populations equal and solve for x, the number of years.
784 - 25x = 817 - 36x
Add 36x to both sides. Subtract 784 from both sides.
11x = 33
Divide both sides by 11.
x = 3

Step-by-step explanation:
You are planning to work in the summer (13 weeks). You
are deciding between working as a lifeguard or a camp counselor. The lifeguard job
pays $12 per hour and a $500 signing bonus. The camp counselor job pays $15 per
hour with no signing bonus.
Answer:
(a) Equations for both
[tex]y = 500 + 12x[/tex] --- lifeguard
[tex]y = 15x[/tex] --- camp counselor
(b) Total pay for 5 days
Lifeguard pays $800
Camp counselor pays $375
(c) Which pays more
Lifeguard job pays more
Step-by-step explanation:
Let
[tex]x \to hours[/tex]
[tex]y \to total\ pay[/tex]
Given
Lifeguard job
[tex]Signing\ bonus = \$500[/tex]
[tex]Rate = \$12/hr[/tex]
Camp counselor job
[tex]Signing\ bonus =\$0[/tex]
[tex]Rate = \$15/hr[/tex]
Solving (a): The equation for both
The total pay for each job is calculated as:
Total Pay = Signing Bonus + Rate * Hours
So, we have:
Lifeguard
[tex]y = 500 + 12*x[/tex]
[tex]y = 500 + 12x[/tex]
Camp counselor
[tex]y = 0 + 15 * x[/tex]
[tex]y = 15x[/tex]
Solving (b): Total pay for 5 days
First, we calculate the total hours worked in 5 days
[tex]x = 5hrs/day * 5days[/tex]
[tex]x = 25hrs[/tex]
So, the pay for each is:
[tex]y = 500 + 12x[/tex]
[tex]y =500 + 12*25[/tex]
[tex]y =800[/tex] --- Lifeguard
[tex]y = 15x[/tex]
[tex]y = 15 * 25[/tex]
[tex]y = 375[/tex] --- camp counselor
Solving (c): Which job pays more
By comparing the solution in (b)
[tex]800 > 375[/tex]
Hence, lifeguard job pays more
