In her metalwork class, Anja cut a square of
tin, of edge 3.7 cm, from a larger square of
edge 6.3 cm. What area of tin was left?

Answers

Given:

Anju cut square of tin, of edge 3.7 cm, from a larger square of edge 6.3 cm.

To find:

The area of the remaining tin.

Solution:

Area of a square is:

[tex]Area=a^2[/tex]

Where, a is the edge of the square.

Area of the smaller square is:

[tex]A_1=(3.7)^2[/tex]

[tex]A_1=13.69[/tex]

Area of the larger square is:

[tex]A_2=(6.3)^2[/tex]

[tex]A_2=39.69[/tex]

The area of the remaining tin is:

[tex]A=A_2-A_1[/tex]

[tex]A=39.69-13.69[/tex]

[tex]A=26[/tex]

Therefore, the area of the remaining tin is 26 sq. cm.

Answer:

8) 50°, 50°, 130°, 130°10) 120°

Step-by-step explanation:

Ex 8

Adjacent interior angles of a parallelogram are supplementary

Let the small angle is x, the other angle is:

2x + 30°

The sum of two angles is 180°

x + 2x + 30° = 180°3x = 150°x = 50°

The angles are 50°, 50°, 130°, 130°

Ex 10

Sum of interior angles of a pentagon is:

S = 180°(5 - 2) = 540°

Two of the angles are supplementary, so they sum to 180°

The sum of the remaining 3 angles is:

3x = 540° - 180°3x = 360°x = 120°

Each of the congruent angles is 120°

a dice is rolled 60 times, what is the probability of it landing on 4

Answers

Find the normal approximation to the chance that the face with six spots appears between 9, 10, or 11 times.

The exact chance that the face with six spots appears 9, 10, or 11 times?

my solution; in one roll of the die P(6 spots)=16 In 60 rolls of the die the expected number of times the face with 6 spots appears is given by E(X)=Mean=606=10 times.

SE(6spots)=SD=SQR(606⋅56)=2.8868

Applying the normal approximation to the chance that the face with six spots appears 10 times, I obtain the following: mean = 10

Standard deviation=2.8868

Using the continuity correction of 0.5 the following z-scores are found: z1=(9.5−10)/2.8868=−0.1732 and z2=(10.5−10)/2.8868=0.1732 Subtracting the cumulative probabilities for the two z-scores gives 0.5688−0.4312=0.1376 which is the approximate chance that the face with six spots appears 10 times. find the six spots appears between 9,10, or 11?

The exact chance that the face with six spots appears 10 times is found from

13). -2x³ + x² + 1   14). x + 10y - 10z   15). -2x³ + x² + 1

Step-by-step explanation:

13). (x³ - x² + 4) - (3x³ - 2x² + 3)

= x³ - x² + 4 - 3x³ + 2x² - 3

= x³ - 3x³ - x² + 2x² - 3 + 4

= -2x³ + x² + 1

14). (3x + 4y - 3z) - (2x - 6y + 7z)

= 3x + 4y - 3z - 2x + 6y - 7z

= 3x - 2x + 4y + 6y - 3x - 7z

= x + 10y - 10z

15). (x³ - x² + 4) - (3x³ - 2x² + 3)

= x³ - x² + 4 - 3x³ + 2x² - 3

= x³ - 3x³ - x² + 2x² + 4 - 3

= -2x³ + x² + 1

Step-by-step explanation:

Solution

Answer: x=-1,1

Step-by-step explanation:

16x^2+9=25 first we subtract 9 from the right and left sides.

16x^2=16

Divide both sides by 16 to isolate x

x^2=1

Take the square roots of both sides to isolate x completely.

x=1,-1

I SHALL REWARD THEE WITH BRAINLIEST Change -2Y - 2X = -6 to the slope intercept form of the equation of a line (I NEED EXPLANATIONS FOR FURTHER QUESTIONS I GET STUCK ON) :3 ty and hawwo

Answers

Answer:

y = -x + 3    

Step-by-step explanation:

First of all, you need to memorize several forms of the equation of a straight line.  Here you have -2y - 2x = -6 in "standard form" and want the equivalent equation in "slope intercept form," y = mx + b.

To get this, solve the first equation for y by dividing all three terms by -2:

y + x = 3.

Then solve this result for y:

y = -x + 3    

This is the desired equation in slope-intercept form.

Nadia needs 2/5 cup of orange juice for a punch recipe. She will double the recipe to make punch for a party. Which statement is true?

Answers

Answer:

Step-by-step explanation:

There's not a lot to go on with the details provided in the question, but based on all you said, if there isn't more to the question, then the true statement is the fact that Nadia needs 2/5 cup of orange juice for punch recipe.

Twice that amount is 4/5, and logically, that can't suffice in a party, except it's a party of 3, maybe 5 people. I'm assuming the people in the party would be much more than that. Makes the fraction impossible
