Answer:
[tex]75\%[/tex]
Step-by-step explanation:
[tex] \frac{3}{4} \times 100\%[/tex]
100 is divided by 4, so you will get 25.
25 multiply 3, you will get 75%
So, the answer is 75%.
Answer:
Step-by-step explanation:
I'm not sure what you're asking for but I'll assume you mean what percentage is the three so:
There are 7 total parts bc 3 + 4 = 7.
3/7 is 42.857142857% repeating decimal
If you mean 3/4 then it's 75% bc 3/4 is 0.75

Answer:
A: (draw figure 3 and on the right end add two more tiles on the top and bottom stack of tiles)
B: Figure 10 will have 20 tiles because each figure is increasing by 2 tiles.
Step-by-step explanation:
The figures are increasing by 2 so we can multiply 2 by 10 to get the number of tiles on the 10th figure.

find the length of BC
Answer:
13.3650978628
Step-by-step explanation:
Angle A=180-(Angle B+C)=180-117=63
Here,
b=BC, p=AC & AB=12
Using the relation of cos,
cosx=b/h
cos27=BC/15
15cos27=BC
Using a calculator,
BC=13.3650978628
hello could you please help me with this math problem with full explanation which I am unable to solve?
Answer:
b) 27
Step-by-step explanation:
sum of angles in triangle = 180
a + 63 + 90 = 180
a = 27
Answer:
27 degrees
Step-by-step explanation:
since angle B is 68 and you know that angle c is a right angle it is 90. so yhu take 90 and 63 and add them together and subtract that number from 180 and you find angle A
On the first two downs, a football team lost a yard and then lost 2 yards.
Write an expression with addition that shows the changes in yards on
the first two downs.
First they lost 1 yard which would be written as -1
Next they let 2 yards which is written as -2
Now add them together: -1 + -2 = -3

Determine the vertex of the function f(x) = 3(x - 2)^2 + 1.
(2, 1)
(-2, 1)
(1,2)
(1,-2)
Answer:
The vertex is at (2,1)
Step-by-step explanation:
The vertex form of a quadratic is
y = a(x-h)^2 +k where (h,k) is the vertex
f(x) = 3(x - 2)^2 + 1.
The vertex is at (2,1)
a piggy bank contains some dimes and nickels. there are 8 more dimes than nickels in the bank. there is a total of $1.40. how many of each ryoe of coin are in the bank?
please give me a simple answer.
Answer:
4 nickels
12 dimes
Step-by-step explanation:
Dimes are worth .1 each while nickels are .05 each.
We have 8 more dimes than nickels. Let d represent number of dimes and n for number of nickels. This means we have d=8+n.
If all our nickels and dimes together are worth 1.4 then we have another equation .1d+.05n=1.4
Lets put our equations together:
d=8+n
.1d+.05n=1.4
‐-----------------Plug first equation into second.
.1(8+n)+.05n=1.4
Distribute
.8+.1n+.05n=1.4
Combine like terms
.8+.15n=1.4
Subtract .8 on both sides
.15n=.6
Divide both sides by .15
n=.6/.15=4
Remember there are 8 more dimes so d=8+4=12.

You add the same amount of money to your savings each week. At week 5 you have $45. At week 12 you have $80. How much money do you have at week 20?
Answer: $120
First, create a function
x = number of weeky = amount of money in savingsa = amount of money added each weekb = the amount of money in savings at week 0[tex]\left \{ {{5a+b=45} \atop {12a+b=80}} \right.\\\\(5-12)a+(1-1)b=45-80\\\\-7a=-35\\\\a=\frac{-35}{-7} =5\\\\5a+b=45\\\\5(5)+b=45\\\\b=45-25=20[/tex]
Therefore, the function is y = 5x + 20
To find the amount of money at week 20, set x = 20 and solve:
[tex]y=5(20)+20=100+20=120[/tex]
Therefore, the answer is $120.
A hollow metal sphere has an external diameter of 12 cm and a thickness of 2 cm. (i) Given that the mass of 1 cm of the metal is 5.4 g, find the mass of the hollow sphere in kg. (ii) The hollow sphere is melted and recast to form a solid sphere. Find the radius of the solid sphere.
Answer:
(i) 3.438159 kg
(ii) 5.336803297 cm
Step-by-step explanation:
the external diameter = 12 cm, => the radius = 6 cm.
the internal diameter = 12 - 2×2 = 8 cm, radius = 4 cm.
I assume the mass of 1 cm³ (not cm) is 5.4 g (very, very light metal).
the material is in the volume of external sphere minus internal (empty) sphere.
the volume of a sphere is
4/3 × pi×r³
V-e = 4/3 × pi×6³ = 4/3 × pi×216 = 4×pi×72 = 904.7786842 cm³
V-i = 4/3 × pi×4³ = 4/3 × pi×64 = 268.0825731 cm³
V-e - V-i = 4/3 × pi×(216-64) = 4/3 × pi×152 = 636.6961111 cm³
1cm³ = 5.4g
636.6961111 cm³ = 5.4×636.6961111 = 3438.159g = 3.438159 kg
for (ii) we need to work with the volume of the material and calculate backwards to find the radius of the sphere with the full volume of that size.
636.6961111 = 4/3 × pi×r³ = 4/3 × pi×152
152 = r³
r = 5.336803297

Answer:
x=(3e+2d)/(2g-ef)
Step-by-step explanation:
d=e(3+fx)/(2+gx)
or, 2d+2gx=3e+efx
or, 2gx-efx=3e+2d
or, x(2g-ef)=3e+2d
or, x=(3e+2d)/(2g-ef)
Answer:
x = (-2d + 3e) / (dg - fe)
Step-by-step explanation:
We solve it by using algebra.
1. Multiply each side by 2 + gx:
dgx + 2d = fxe + 3e
2. Subtract fxe on both sides:
dgx − fxe + 2d = 3e
3. Subtract 2d from both sides:
dgx − fxe = −2d + 3e
4. Factor out x:
x (dg − fe) = −2d + 3e
5. Divide dg - fe:
x = (-2d + 3e) / (dg - fe)

Find an equation for the line of best fit for the table below.
Answer:
first or last depending how you are rounding the decimal
=> the best fit is the first one
Step-by-step explanation:
y = 2.55x - 2.15 when x = 5 => y = 10.6 approximately 11
y = 3.21x - 1.75 when x = 5 => y = 14.3 cannot equal or approximately 11
y = -2.15x + 2.55 when x = 5 => y = -8.2 cannot equal or approximately 11
y = 1.75x + 3.15 when x = 5 => y = 11.9 approximately 11

In parallelogram ABCD, m∠B = 105°.
What is the value of x. (Round your answer to the nearest tenth, if necessary.)
Answer:
52.5
Step-by-step explanation:
Since ED ≈ AD, ∆AED is a isosceles triangle where <EAD and <AED has same angle measurement
Now, m<B = 105°, since ABCD is a parallelogram, <B = <D
so, m<ADC = 105° so, m<ADE = 180°-105° = 75°
Now, m<EAD+m<AED+m<ADE = 180°
or, m<AED+m<AED+m<ADE = 180°
or, x+x+75°=180°
or, 2x=180+75°
or, 2x=105°
or, x=52.5°

What is one possible perimeter of the garden, in meters?
Answer:
24.1 is a possibility for the perimeter
Step-by-step explanation:
The third side between 12+0.5 and 12-0.5, or 12.5 and 11.5.
The third side is between 11.5 and 12.5.
Simce it isn't isosceles third side can't be 12.
So it's asking you to choose a number between 11.5 and 12.5 with the exclusiion of 12 for the third side measurement in meters.
So let's choose 11.6.
So the perimeter is just the sum of all side measurements.
11.6+12+0.5
11.6+0.5+12
12.1+12
24.1
24.1 is a possibility for the perimeter
