Answers
Answer:
D. 1/2m + 25
Step-by-step explanation:
Sophie pays m dollars to rent a car for the weekend.
On the drive home, she buys $25 worth of gasoline.
From the above question, we are told that:
Her friend Melody pays for one-half the cost of the car rental only.
= m - 1/2m
= 1/2m
Hence, the cost of the rental that sophie is paying for is 1/2m dollars
She buys $25 of gasoline
Let the amount sophie spent be represented by A
The expression you could use to determine how much Sophie spent is given as:
A = 1/2m + 25
Answer:
1/2 + 25

An item is regularly priced at $65. Abdul bought it at a discount of 95% off the regular price. Use the ALEKS calculator to find how much Abdul paid.
Answers
Answer:
$3.25
Step-by-step explanation:
An item is regularly priced at $65. Abdul bought it at a discount of 95% off the regular price. Use the ALEKS calculator to find how much Abdul paid.
Original price of item = $65
percent discount = 95%
discount price = 95% * 65
discount price = 0.95 * 65
discount price= $61.75
Amount abdul paid = Original price - discounted price
Amount abdul paid = $65 - $61.75
Amount abdul paid = $3.25
Hence abdul paid $3.25

two angles of an isosceles triangle are x and x+10.find two possible value of x
Answers
Recall two important facts:
- An isosceles triangle always has two identical angles
- The interior angles always add up to 180 degrees
Armed with this info, we can set up two different equations to solve for x, depending on which angle we treat as being one of the pair of identical angles.
If we assume that the identical angles are x, then:
180 = 2x + x + 10
170 = 3x
56[tex]\frac{2}{3}[/tex] = x
Alternately, we can assume that the identical angles are x+10. In this case:
180 = 2(x + 10) + x
180 = 2x + 20 + x
160 = 3x
53[tex]\frac{1}{3}[/tex] = x

Answers
Answer:
The reason is likely because of an unit error of centimetres square (cm²) which is to be in metres square (m²)
Step-by-step explanation:
The units of the length is in meters, and the side length, S, of the cube is S = 0.7 m, therefore, the answer is to be given as follows;
The surface area of one face of the cube = S² = (0.7 m)² = 0.49 m²
The number of faces in a cube = 6, therefore, we have;
The surface area of the cube = 6 × The surface area of one face of the cube
The surface area of the cube = 6 × 0.49 m² = 2.94 m²
Therefore, the surface area of the cube is 2.94 m² (m² not cm²)

a. 3x ^4y^2z^6
b. 3x ^5y^3z^6
c. 3x^5y^3/z^6
d. 3y^2/x^4z^6
Answers
Answer:
d
Step-by-step explanation:
because
12xy³z⁶/4x⁵yz¹²=3y²/x⁴z⁶
The division of (12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex]) is 3y²/ [tex]x^4[/tex][tex]z^6[/tex].
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.
Given:
(12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex])
Now, expand for the division
12/4= 3
x / [tex]x^5[/tex] = 1/ [tex]x^4[/tex]
y³ /y = y²
[tex]z^6[/tex] / [tex]z^{12[/tex]= 1/[tex]z^6[/tex]
So, the division is
(12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex])
= 3y²/ [tex]x^4[/tex][tex]z^6[/tex]

Two shops, Tisco and Azda, sell the same brand of baked beans with the following deals.
Calculate the price per item for each shop.
Write the shop which is the best value for money in the comment box.
Tisco - 4 for £1.84
Azda - 5 for £2.40
Answers
Answer:
The shop with the best value is Tisco with .46 per can.
Step-by-step explanation:
So you need to divide 1.84 by 4 which you get .46. Next you do 2.40 divided by 5 and you get .48. Finally you can tell that .48 is greater than .46.

Answer:
The answer is 15.
Step-by-step explanation:
Plug in the numbers for the a and b values individually. For the numerator, 5(6) is the same thing as 5 * 6 = 30. For the denominator, 1/4^2 would equal to 1/16 and when you multiply it by 32, you will get 2.
To clear things up, the fraction should be 30/2 and your answer should be 15 as a result.
