Answer:
£12
Step-by-step explanation:
It's asking us to find the 30% of the 40 and to do this we multiply 40 by 30 then divide it by 100
40 × 30 ÷ 100 = 12

Answer:
x = 2
Step-by-step explanation:
(Square both sides)
20 - 8x = x^2
(Solve 20 - 8x = x^2)
x = 2 , x = 10
x = 10 is false, so the answer is x = 2.
Answer:
x=2
Step-by-step explanation:
√20-8x=x
2√5-2x=x (by simplfing redical expression)
4(5-2x)=x^2 (square both side)
20-8x=x^2
20-8x-x^2=0
-x^2-8x+20=0
x^2+8x-20=0
x=2

–24 + 12d = 2(d – 3) + 22
Answer:
d = 4
Step-by-step explanation:
Answer:
d = 4
Step-by-step explanation:
–24 + 12d = 2(d – 3) + 22
–24 + 12d = 2d - 6 + 22
–24 + 12d = 2d + 16
–24 + 12d - 2d = 16
12d - 2d = 16 + 24
10d = 16 + 24
10d = 40
d = 4

Solve by factoring. Check your answer.
[tex]x^2-4x=0[/tex]
Please show all your work and explain all steps. Thanks :)
Answer:
[tex]x=0,4[/tex]
Step-by-step explanation:
Factor out the common terms from the given terms:
[tex]x^2-4x=0[/tex]
You can factor out x from both:
[tex]x(x-4)=0[/tex]
Rewrite, setting each equal to 0:
[tex](x)(x-4)=0\\\\x=0\\\\x-4=0[/tex]
Simplify the second equation by solving for x:
[tex]x-4=0\\\\x-4+4=0+4\\\\x=4[/tex]
Therefore, x=0 or x=4

If Osa is in a submarine that is 275 feet below sea level and Jill is hiking a mountain and is at 250 feet above sea level, which person is closest to sea level? Explain how you used math to determine your answer.
Answer:
Jill
Step-by-step explanation:
Since 250 is closer to 0 (which is the sea level) on the number line compared to 275, Jill is closer to sea level.
5. What is the equation of a line that is perpendicular to -x + 2y = 4 and passes through the point (-2,1)?
a.
Write the equation -x + 2y = 4 in slope-intercept form
b. Identify the slope of the line represented in part a.
C.
What is the slope of the line perpendicular to the line in steps a and b?
d. Write the equation of the perpendicular line in slope-intercept form.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]-x + 2y = 4[/tex]
a) writing the equation in the slope-intercept form
We know that the slope-intercept form of the equation of the line is
[tex]y=mx+b[/tex]
where m is the slope of the line
so writing the equation in the slope-intercept form
[tex]-x + 2y = 4[/tex]
[tex]2y=4+x[/tex]
[tex]y=\frac{1}{2}x+2[/tex]
b) Identify the slope of the line represented in part a
As the equation in slope-intercept form is
[tex]y=\frac{1}{2}x+2[/tex]
Here,
m = slope = 1/2 ∵ [tex]y=mx+b[/tex]
c) What is the slope of the line perpendicular to the line in steps a and b
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
As the slope = 1/2
So the slope of the perpendicular line will be: -2
d. Write the equation of the perpendicular line in slope-intercept form.
Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2,1) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -2 and the point (-2,1)
[tex]\:y-1=-2\left(x-\left(-2\right)\right)[/tex]
[tex]y-1=-2\left(x+2\right)[/tex]
Add 1 to both sides
[tex]y-1+1=-2\left(x+2\right)+1[/tex]
[tex]y=-2x-3[/tex]

Answer This CORRECTLY. I really need help, the question will be placed first, and then the answer choices will be in order from A - D as graphs.
Answer:
C is the correct oneStep-by-step explanation:
GivenFunction
y = -3/2x - 2To find The correct graphSolutionWe can see all 3 graphs have y-intercept of -2
Since the slope is negative, it is decreasing function, therefore possible options are A or C
Checking x-intercept and comparing with same of A and C
y = 0-3/2x - 2 = 0-3/2x = 2x = -4/3 = -1.33As we see it matches Option C, which is the answer

Answer:
a. h(t) = 5t + 10
b. 70
c. h(5) = 35 means that in 5 seconds, it will be 35 feet above ground.
Step-by-step explanation:
a. Since the elevator is already 10 feet of the ground, u have to add that in the equation. And since it's 5 feet per second, 5 will be a multiplier so:
h(t) = 5t + 10
b. We have the equation already and in the equation it said that "t" represents the seconds so just replace 1 with 12:
h(12) = 5(12) + 10
h(12) = 60 + 10
h(12) = 70
c. Refer to b that we just did if u will, "t" represents seconds so h(t) becoming h(5) means 5 seconds. So h(5) = 35 means that in 5 seconds, it will be 35 feet above ground.

Which store offers the best store
Store X:4 cans for $2.38
Store Y:5 cans for $3.00
Store Z:59 cents per can
Store Z
Step-by-step explanation:1 - Find out what the price per can is at each store
Store X
4 cans for $2.38
2.38price/4can(s) = price per can
Store x is $0.598/can
Store Y
5 cans for 3.00
$3.00/5
$0.60/can
Comparing these to store Z; store Z is still the better deal.

I need hep with the range
Answer:
[-7, 6]
Step-by-step explanation:
The range is the y values that the equation/line covers.
The line's lowest point is -7 and the line's highest point is 6. The value is defined at both -7 and 10 since there is a closed circle in both locations- so we use brackets.

If m_ABD = 64°, and mZCBD = 30°,
then m ABC = [?]°
Answer:
34 degrees
Step-by-step explanation:
If ABD = 64, and CBD is 30, we can use PWP( Part Whole Postulate)
Step 1.CBD + ABC = ABD
Step 2. Substitute
30 + ABC = 64
Step 3. Isolate ABC
34 = ABC
ABC is 34 degrees
9514 1404 393
Answer:
34°
Step-by-step explanation:
It should be fairly intuitive that the two smaller angles add to give the value of the larger one. (Even if it's not, the angle sum theorem tells you this is true.)
∠ABC + ∠CBD = ∠ABD
∠ABC + 30° = 64°
∠ABC = 34° . . . . . . . . . subtract 30° from both sides of the equation
Keenan buys an embroidery machine for $1,400. He uses it to embroider T-shirts. His total profit in dollars from selling the T-shirts is represented with the function f(x) = 12x − 1,400. When the machine breaks, he pays $135 to have it fixed. How does that cost affect a graph of Keenan’s profit function?
Answer:
the graph shift down 135 units
Step-by-step explanation:
when there is no fixing cost:
f(x)=12x-1400
when there is fixing cost (0ne time): 12x-(1400+135)
the graph shift down 135 units

1.) Select the correct equation for the following situation. Mariana had 134
crystals in her collection. This was 38 less than Rajesh's collection. How
many crystals are in Rajesh's collection?
38r = 134
r+ 38 = 134
r - 38 = 134
38 - r = 134
Answer:
r minus 38 equals to 134 this might be m not certain
The correct equation is, [tex]r-38=134[/tex] and Rajesh have 172 crystals .
Let us consider that, Rajesh had r crystals.
Mariana had 134 crystals in her collection.
Since, Rajesh has 38 more crystal than Marina . So , if we subtract 38 from crystals Rajesh have then both have equal number of crystals.
So, [tex]r-38=134[/tex]
Now, find crystals present in Rajesh collection.
[tex]r-38=134\\\\r=134+38=172[/tex]
Thus, Rajesh have 172 crystals .

Answer:

Step-by-step explanation:
The graphs of positive and negative x^2 parabolas will always have a domain of all real numbers. Even though you only have a portion of the graph and see a "restriction" on your domain values, it is incorrect to assume that the domain is limited to what you can see. As the branches of the parabola keep going up and up and up, the values of x keep getting bigger and bigger and bigger. Again, this is true for all + or - parabolas. ....... Can consider brainlist*:)
