Answer:

see explanation

Step-by-step explanation:

(a)

The student has distributed the second parenthesis by 1 instead of - 1

(b)

Given

(x² - 3x + 4) - (x³ + 7x - 2)

distribute the first parenthesis by 1 and the second by - 1, that is

= x² - 3x + 4 - x³ - 7x + 2 ← collect like terms

= - x³ + x² - 10x + 6

Step-by-step explanation:

Answer:

The properties of trapezoid apply by definition (parallel bases).

The legs are congruent by definition.

The lower base angles are congruent.

The upper base angles are congruent.

Any lower base angle is supplementary to any upper base angle.

The diagonals are congruent.The bases are parallel by definition.

Each lower base angle is supplementary to the upper base angle on the same side.

Answer:

2262 in³

Step-by-step explanation:

Given that:

Height, h = 20 inches

Radius, r = 6 inches

Volume of a cylinder is given as :

V = πr²h

V = π * 6² * 20

V = π * 36 * 20

V = 2261.9467 in³

Hence, Nicholas pot can hold about 2262 in³ of soup

Answer:

105

Step-by-step explanation:

To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.

To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.

Step-by-step explanation:

Answer:

Y = 1

Step-by-step explanation:

Proportional

Answer:

y=1

Step-by-step explanation:

Because they are proportional, the two points have to be equal if they were like a fraction. This means (15,3) would be 15/3 which is equal to 5. The other point is (5,?), so that means that the point will have to be 1. This is because then the point will be equal to 5.

Answer:

Step-by-step explanation:

70p/5=14

14*4=56*10=560p

14*3=42*20=840p

840+560+70=1470

=1470p or (£14.70)

The total value of money in the jar is 270p.

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

The number of 5p, 10p, and 20p coins in a jar are in the ratio 7:4:3.

That means,

Number of 5p coins are 5x, 10p coins are 4x and 20p coins are 3x.

And 5p coins are worth 70p.

That means, x = 70p/5p

x = 14

So,

The total worth of coins are,

= 70p + 80p + 120p

= 270p

Therefore, the worth of the coins are 270p.

Answer:

H0: μ1 = μ2

H1: μ1 ≠ μ2 ;

xbar1 - xbar2

Step-by-step explanation:

The Null hypothesis should state that there is no difference in average household income between those located east and west of the Mississippi

H0: μ1 = μ2

H1: μ1 ≠ μ2

Statistic from the sample that would be used to estimate difference

Statistic refers to the numerical characteristic derived from the sample.

To estimate the difference in the average household income between those located east and west of the Mississippi, we take the sample mean of the two groups

Group 1, East of Mississippi = xbar 1

Group 2, West of Mississippi River = xbar 2

xbar1 - xbar2

Answer:

Angle 4=82 degrees, then i think angle 1 and 3= 98 degrees

Step-by-step explanation:

Angle 2=Angle 4 and 180-82=98

Answer:

Step-by-step explanation:

1) 5a - 2b² + 1

Degree of the polynomial = 2

2) 4x²-3x³ + 2x + 12

-3x³ + 4x² + 2x + 12

Degree of the polynomial = 3

To find the degree of the polynomial, arrange it in descending as per the power of the variables.

The highest power of the variable is the degree of the polynomial.

The percentage difference in the amounts made is 30%.

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.

Percentage difference= [ (amount made this year / amount made last year) - 1 ] x 100

'(650,000 / 500,000) - 1] x 100 = 30%

Answer:

using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2

a²+b²=c²

(9/10)²+(11/5)²=(11/2)²

81/100+121/25=121/4

lcm of 25 and 100 =100

(81+484)/100=121/4

565/100=121/4

113/20=121/4

since they are not equal therefore it's not a right angle triangle
