Armando has collected 39 bottle caps in the past three months. At this rate, how many bottle caps will he have
in five months?
Answer:
I think it's 115
Step-by-step explanation:
because there a 30 days in month and 39/30 is .77 so if you multiply that by 5 months which equals 150 days you'll get 0.77 × 150 which equals 115
What is the Solution of the equation y=2x+3
Answer:
let X interchange y and vice versa
X= 2x+3
carry across +3
X-3=2X
carry across 2 (2X is 2 multiple by X when carried across the sign change to division)
so X-3 divided by 2 is = X
could be misinterpreting this question so I'm not entirely sure.
Alex only keeps ten pence coins and some twenty pence coins in
his coin box. He has a total of 18 coins which amounts to £2.30.
Work out the number of ten pence coins and twenty pence coins
in Alex's coin box.
Answer:
In the box. we have 5 20 pence coins and 13 10 pence coins
Step-by-step explanation:
Let the number of 10 pence coins be x and the number of 20 pence coins be y
The sum of these numbers is 18
Thus;
x + y = 18•••••••(i)
Writing the value in pence only
£2.30 * 100 = 230 pence
Now we have that;
total 10 pence coin amount = 10 * x = 10x
Total 20 pence coin amount = 20 * x = 20y
10x + 20y = 230
x + 2y = 23 •••••••(ii)
from ii;
x = 23-2y
Substitute this into i
23-2y + y = 18
23-18 = 2y-y
y = 5
Recall;
x + y = 18
x + 5 = 18
x = 18-5
x = 13
Need help because i can’t seem to figure it out

Answer:
y -10 = 1/8(x +8)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You have m = 1/8, and (h, k) = (-8, 10).
Putting those numbers in the form gives ...
y -10 = 1/8(x -(-8))
You can simplify the double minus sign so you have ...
y -10 = 1/8(x +8)

in a circle of radius 17cm calculate the length of a chord which is 8cm from the centre
Answer:
The length of the chord is 30cm
Step-by-step explanation:
Given
[tex]r = 17cm[/tex]
[tex]d = 8cm[/tex]
Required
Calculate the chord length (L)
This is calculated as:
[tex]L = 2 * \sqrt{(r^2 -d^2)[/tex]
So:
[tex]L = 2 * \sqrt{(17^2 - 8^2)[/tex]
[tex]L = 2 * \sqrt{225[/tex]
[tex]L = 2 * 15[/tex]
[tex]L = 30cm[/tex]

what is the slope of the line that has a y - intercept of -1
Answer:
Slope = 2
Step-by-step explanation:
The line with the y-intercept of -1 has a slope of 2. You can find this by using the formula (y1-y2)/(x1/x2), in other words, rise over run.

brian made a tasty burger . the diameter of the buger was 5cm what is the radius of the circle
Answer:
2.5 centimeters
Step-by-step explanation:
The radius is half the diameter of a circle.
The diameter of the burger is 5 cm.
5/2 = 2.5
The radius of the burger should be 2.5 centimeters.
Hope this helps!
Answer:
The marginal utility per dollar spent for the second burger is 4 utils and the utility per dollar spent for the second burger is 4.5 utils.

What value of x is the solution to the equation 2x+4=−2
Answer:
I got -3 as the answer .........
Find the value of x in the figure below
x =
degrees
x =
degrees
Answer:
x = 190 and x = 126
Step-by-step explanation:
In both diagrams the indicated angles are vertical and congruent, then
[tex]\frac{x}{2}[/tex] = 95 ( multiply both sides by 2 )
x = 190
and
x + 21 = 147 ( subtract 21 from both sides )
x = 126

An architect is making a plan for a new circular playground. If the picture below is the
playground, how much fencing needs to go up to
keep the kids in the circle?
Answer:
201ft
Step-by-step explanation:
The circumference of a circle is equal to
C=piD
d=64ft
substitute:
c=pi(64)=64pift ft
assume pi=3.14
64pi=64*3.14=200.96ft
round to the nearest whole number:
200.96=201ft
another explanation:
Answer:
Length of the fencing required = 201.06 meters
Step-by-step explanation:
Architect is planning a circular playground with diameter = 64 m
We have to calculate the fencing required to cover this playground.
Length of fencing = circumference of the playground
Since circumference of a circle = π × (Diameter)
= 64π
= 201.06 meters
Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.
200.96 meters of fencing needs to go up to keep the kids in the circle. Therefore, option D is the correct answer.
What is circumference of a circle?The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.
Given that, diameter of a circle is 64 meter.
Here, the radius = 64/2
= 32 meter
We know that, the circumference of a circle can be calculated using 2πr.
Now, circumference = 2×3.14×32
= 200.96 meters
Therefore, option D is the correct answer.

Step-by-step explanation:
h(x)= (x+10)(x+2)
^ It is this way because it is so the x value will equal -10 and -2.
Now, we just distribute it. if the question does not have any points it passes through described in the problem, then it is pretty self explanatory.
x^2 + 2x+ 10x+ 20
= [tex]x^{2} +12x+20[/tex]
