Answer:
71%, without rounding 70%
Step-by-step explanation
We know our total number of marks is 79 if we only get 56 out of 79 we take 56/ 79. You'll end up with a number of 0.7088. You will ALWAYS end up with a decimal point. Because its a percentage we move the decimal point over 2 spots making the number 070.88 the 0 in front of of the 70.88 gets removed so you're left with 70.88 so rounded it would be 71%. Hope this helps
Answer:
70.88% or 70.9%(if rounded off)
Step-by-step explanation:
1. 100 ÷ 79 = 1.2658227848
2. 1.2658227848 × 59 = 70.8860759494
3. 70.88 rounded off to the nearest tenths is 70.9

Answer:
4.) Cost of cordless phone = $55
cost of each additional handset = $25
Therefore, the overall cost of the cordless phone, including the 3 extra handsets is:
$55 + 3($25) = $55 + $75 = $130
5.) Given the function, f(d ) = .20d + 14, where:
f(d) = global temperature (in Celsius)
d = number of decades
To evaluate the value of f (d ) at f(10), you'll have to substitute the value of d = 10 as input into the function:
f(10) = .20(10) + 14
f(10) = 2 + 14
f(10) = 16
6.) Value of f(10):
In 10 decades, the predicted global temperature will be 16° Celsius.
7.) The correct answer is B. The global temperature f(d) depends on the number of decades, d.
Explanation: the independent variable is d → it is the input of the function. The output primarily depends on the given value of input.
8.) Given the function, f(t ) = 0.2t
where t = represents number of days elapsed since the planting of the seed.
Evaluate f(40):
f(40) = 0.2(40)
f(40) = 8
Context of f(40): The value of the function, f(40) = 8 represents the 8 centimeter height of the habanero plant after 40 days of planting its seeds.

Answer:
12 and (-12)
Step-by-step explanation:
Solve for x.
x^2= 144
square root both sides and get,
x= 12
and
x= (-12)
remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.
Answer:
x = 12
x = -12
Step-by-step explanation:
Step 1: Take the square root of both sides.
[tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x = 12[/tex] or [tex]x = -12[/tex]Therefore, x = 12 and x = -12 are the answers.

You get a third of some number x if you divide x by 3.
So, one third of (1/3)⁸ is
(1/3)⁸ / 3 = (1/3)⁸ × 1/3 = 1/(3⁸⁺¹) = 1/3⁹
The graph represents function 1 and the equation represents function 2:
A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.
Function 2
y = 4x + 1
How much more is the rate of change of function 2 than the rate of change of function 1?
A)1
B)2
C)3
D)4
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.
Step-by-step explanation:The rate of change is also known as slope. The slope of a linear function or a line is
It is given that the function 1 is passing through the points (0,3) and (4,3). Slope of function 1 is
Therefore the slope of first function is 0.
The slope intercept form of a line is
Where, m is the slope and b is y-intercept.
The second function is
Therefore the slope of second function is 2 and the y-intercept is 1.
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

For the standard normal distribution, the area between z = 0 and z = 1.70, rounded to four decimal places, is:
Using normal distribution table, the area between z=0 and z=1.70 is the difference between p(z=0) and p(z=1.70). Hence, the area between z=0 and z = 1.70 is 0.4554
Using a normal distribution table :
P(Z < 0) = 0.5 P(Z < 1.70) = 0.95543The Area between z=0 and z= 1.70 is defined as the difference between the probabilities of (z < 1.70) and (z < 0)
P(Z < 1.70) - P(Z < 0) = 0.95543 - 0.5 = 0.45543
Therefore, the area between z = 0 and z = 1.70 rounded to four decimal places is 0.4554

hi! for this problem, all we need is the equation for the SA for a cylinder!
here's the equation: [tex]A=2\pi(r)(h)+2(\pi)r^{2}[/tex]
BUT FIRST let's identify our given numbers
the radius, or r, is 4 (r = 4) the height, or h, is 10 (h = 10)now all we have to do is plug in what is given to the equation above! not so bad, right?
plugged in equation
[tex]A = 2\pi (4)(10) + 2\pi (4)^{2}[/tex]

Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Jenny explains that this is not the most efficient way to solve. Explain who is correct & justify your reasoning.
The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method
The given equation is [tex]\frac{x}{3} + 8 = -2[/tex]
Solving the equation using Natasha's method
the fist step is to multiply by 2
x + 24 = - 6
The second step is to combine and add similar terms
x = -24 - 6
x = -30
Second method of solving the equation
The equation the friends are trying to solve is [tex]\frac{x}{3} + 8 = -2[/tex]
The first step is to combine similar terms
[tex]\frac{x}{3}[/tex] = - 8 - 2
The second step is to add similar terms together
[tex]\frac{x}{3}[/tex] = - 10
The third step is to multiply both sides of the equation by 3
x = (-10 x 3)
x = -30

What is the = to 5x+ 7 =42 please give details
Answer: x = 7
Step-by-step explanation:
5x + 7 = 42
We then take 7 away from both sides:
5x = 35
Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.
x = 7
