Answer:
£12000
Step-by-step explanation:
Granddaughter -- 1/2 of x
Grandson -- 1/2(1/2 of x)
Brother -- 1/6 of x
Dogs' home -- £1000
Therefore,
[tex]\frac{x}{2} + \frac{x}{4} + \frac{x}{6} + 1000 = x[/tex]
x = 12000

Max completed 12 questions on the exam. This is 40% of the questions. 1. Write an equation representing this situation. 2. How many questions are on the exam? 3. Explain how you got your answer
Answer:
Step-by-step explanation:
How many questions are on the exam? Represent this by n.
Then 40% of n comes out to 12 questions, or more symbolically,
0.40n = 12, after which we get n = 12/0.40 = 30
Answers:
(1) 0.40n = 12 is the desired equation.
(2) n = 30 is the number of questions on the exam.
(3) See above for explanations.

(2^2)^4 = 256
3^4 = 81
256 × 81 = 20735
27 × 16 = 432
20735÷432 = 47.99
round to 47.99 to the nearest 10th and you will get 48.
Lol
Final answer : 48
Please help in maths
Step-by-step explanation:
subtract the areas of a circle from the area of a square and divide by 4
A_square = L x W
A_circle = pi x r^2
L, W= 12cm
r= 12/2cm
(A_square - A_circle) / 4
divide by 4 since the remaining portions are symmetrical
What is the solution to the following equation?
7x−5=2x+5
Answer:
x = 2
Step-by-step explanation:
7x−5=2x+5
step 1 add 5 to each side
-5 + 5 = cancels out
5 + 5 = 10
we now have 7x = 2x + 10
step 2 subtract 2x from each side
2x - 2x cancels out
7x - 2x = 5x
we now have 10 = 5x
step 3 divide each side by 5
5x / 5 = x
10 / 5 = 2
we' re left with x = 2

Shea works in a lab. It takes Shea 30 minutes to calibrate her lab instrument. If she calibrated it 5 times last month, how many hours did she spend calibrating it?
Answer:
2 and a half hours
Step-by-step explanation:
since it takes 30 min to calibrate, and she did it 5 times, that is 5x30 which is 150 minutes, 150 minutes is 2 and a half hours
Solve the quadratic equation by completing the square. 0 = x2 – 6x + 4 –4 = x2 – 6x –4 + 9 = (x2 – 6x + 9) 5 = (x – 3)2
Answer:
x = 3±√5
Step-by-step explanation:
Given the quadratic equation;
0 = x² – 6x + 4
Swap sides
x² – 6x + 4= 0
Subtract 4 from both sides
x² – 6x + 4 - 4= 0 - 4
x² – 6x = -4
Complete the square;
Add the square of half of coefficient of x to both sides
Coefficient of x = -6
Half of Coefficient of x = -6/2 = -3
square of the half of Coefficient of x = (-3)²
Add (-3)² to both sides
x² – 6x + (-3)² = -4 + (-3)²
(x-3)² = -4 + 9
(x-3)² = 5
Take the square root of both sides
x - 3 = ±√5
x = 3±√5
This gives the solution to the equation

Is a triangle with side lengths of 10, 11, 14 a right triangle?
Answer:
no
Step-by-step explanation:
A right triangle has a formula a^2+b^2=c^2 with c being the longest side (hyponotuse). 10 squared is 100, 11 squared is 121, so add those and get 221. 14 squared is only 196 which is not equal to 221 so it is not a right triangle
Answer:
Yes

14.4 = -2.4b
Answer:
b = -6
Step-by-step explanation:
14.4 = -2.4b (swap the sides of the equation)
-2.4b = 14.4 (divide both sides of the equation by -2.4)
b = -6

12) There are two rectangular doors that are similar. The smaller door has a height of 3 ft. and a width of 2 ft. The bigger door has a width of 8 ft. What is the height of the bigger door? (Draw a picture, set up a proportion, and show all work.)(3pts)
Answer:
it's twelve you're welcome
Answer:
12 ft
Step-by-step explanation:
Since the doors are similar then the ratios of corresponding dimensions are equal.
let x be the height of the bigger door, then
[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )
2x = 24 ( divide both sides by 2 )
x = 12
Height of the bigger door is 12 ft

Evaluate the polynomial function when H=3
f(h)=4h^3-3h^2+5h-16
Answer:
80
Step-by-step explanation:
f(3)=4(3)^3-3(3)^2+5(3)-16
f(3)=4(3*3*3)-3(3*3)+15-16
f(3)=4(27)-3(9)+15-16
f(3)=108-27+15-16
f(3)=81+15-16
f(3)=96-16
f(3)=80

What is the product of 7.1 * 10^3 and 5.8 * 10^2 expressed in scientific notation?
Answer:
4.118 * 10^6
Step-by-step explanation:
When you multiply exponents, you just add the exponents together, so 10^2 * 10^3 is 10^5. Then you just multiply the 7.1 and the 5.8, which is 41.18. However, scientific notation should have only 1 digit above the decimal spot, so you make the number smaller from 41.18 to 4.118, so you add 1 exponent to the 10^5.
41.18*10^5 = 4,118*10^6
(EDIT, THE GUY WHO COMMENTED IS CORRECT, SCIENTIFIC NOTATION IS WHEN THE DIGIT IS GREATER THAN 1 OR LESS THAN 10, SO IT WOULD BE 4.118*10^6)
Answer:
411.8 · [tex]10^{4}[/tex]
Step-by-step explanation:
7.1 · 10³ × 5.8 · 10²
7.1 × 5.8 = 41.18
10³ + 10² = [tex]10^{5}[/tex]
41.18 · [tex]10^{5}[/tex]
Scientific notation can only have one digit after the decimal.
411.8 · [tex]10^{4}[/tex]
