I'm doing my missing assignments, help me solve this please, and don't report me because it's not a test

Step-by-step explanation:

Let the larger number be x and smaller number be y.

→ Sum of two numbers = 90

→ x + y = 90_(1)

Also,

→ Larger number = 14 + 3(Smaller number)

→ x = 14 + 3y_(2)

Substitute the value of x from equation (2) to (1) :

→ x + y = 90

→ 14 + 3y + y = 90

→ 14 + 4y = 90

→ 4y = 90 - 14

→ 4y = 76

→ y = 76 ÷ 4

→ y = 19

And, from the equation (2) ;

→ x = 14 + 3y

→ x = 14 + 3(19)

→ x = 14 + 57

→ x = 71

Therefore, larger number is 71 and smaller number is 19.

Answer:

10 incorrect answers

Step-by-step explanation:

Correct answer = +3

Incorrect answer = - 1

Mark scored = 20

Number of correct answers = 10

Let:

Incorrect answers = y

Hence, we can fashion out the expression for total score :

(Number of correct answers * score per Correct answer + number of incorrect * score per incorrect) = total score

(10 * 3) + (y * - 1) = 20

30 - y = 20

-y = 20 - 30

-y = - 10

y = 10

Answer:

Step-by-step explanation:

This is arithmetic since adding 4 to each term gets us to the next term in the sequence. That means that the common difference, d, is 4. The general arithmetic explicit formula is

[tex]a_n=a_1+d(n-1)[/tex] and using the info given when a1 = 3 and d = 4:

[tex]a_n=3+4(n-1)[/tex] or, if you want to make it easier to deal with:

[tex]a_n=4n-1[/tex] (I just distributed through the parenthesis and then combined like terms. As you can see, arithmetic sequences are linear).

Answer:

3

Step-by-step explanation:

y = mx + b

m = slope

In this equation,

m = 3

Thus, the slope, or m, is 3.

General equation for slope-intercept form

y=mx+C

where m is slope

Comparing the given eqn y=3x

m= 3

Therefore, slope = 3

Answer:

  3

Step-by-step explanation:

The common difference of an arithmetic sequence is the slope of the equation that describes it. The slope formula is useful in this case:

  m = (y2 -y1)/(x2 -x1)

  m = (219 -213)/(4 -2) = 6/2 = 3

The common difference of the corresponding arithmetic sequence is 3.

Answer:

81.25

Step-by-step explanation:

Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.

Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.

Finally, add those two distances together so that you know the total distance:

49.75+31.5 = 81.25

Answer:

Hannah has 56

Step-by-step explanation:

Hannah receives 7 for every 3rd Zoe gets. Take Zoe's amount, divide it by three, and you get 8. 8*7 is 56.

Answer: 10 inches.

Step-by-step explanation:

v=l*w*h

Let’s plug in your numbers:

4,331.25=22.5*19.25*h

Let’s simplify it.

4,331.25=433.125*h

Then divide both sides by 433.125 (.125=1/8 by the way).

10=h

The height is 10 inches.

Answer:

B and C

Step-by-step explanation:

(15)

The opposite sides of a parallelogram are equal , so

CD = AB , that is

7x - 54 = 5x - 2 ( subtract 5x from both sides )

2x - 54 = - 2 ( add 54 to both sides )

2x = 52 ( divide both sides by 2 )

x = 26

Then

CD = 7x - 54 = 7(26) - 54 = 182 - 54 = 128 → B

(16)

Consecutive angles are supplementary, sum to 180° , then

6y + 19 + 2y + 9 = 180

8y + 28 = 180 ( subtract 28 from both sides )

8y = 152 ( divide both sides by 8 )

y = 19

Then

∠ B = 6y + 19 = 6(19) + 19 = 114 + 19 = 133°

Opposite angles are congruent , so

∠ D = ∠ B = 133° → C

Answer and Step-by-step explanation:

In a polygon, when a shape is similar but dilated, the angles are still congruent.

Also, turn the pentagon QRSTP counterclockwise 90 degrees so it is upright and looks like pentagon ABCDE (making it easier to read).

A. The measure of angle P is 124 degrees, as it matches up with angle E.

B. To find the length of side r, we need to find the scale factor. We do this by looking at the given side on pentagon QRSTP (side RS) and match it with its similar side of pentagon ABCDE (side BC)

To find the scale factor, you divide the side of the bigger shape by the side of the smaller shape. For us, this results in the scale factor being 2.

Now, the similar side to r is side ED. We need to divide 7.5 by 2 to find r.

When doing so, we get r to be 3.75.

Error interval for x is 4.65 ≤ x < 4.75.

Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.

The error is rounding the number is half of the unit of measure.

The number was rounded to the nearest 0.1 unit. so the error is half of 0.1 which is [tex]\frac{1}{2}[/tex] × [tex]0.1[/tex] = 0.05

∵ 4.7 + 0.05 = 4.75

and 4.7 - 0.05 = 4.65

Error interval for x is 4.65 ≤ x < 4.75.

Answer:

23.32 Miles

Step-by-step explanation:

According to the Question,

(For Diagram Please Find in Attachment)

In Triangle ABC , Apply Pythagoras Theorem, We get

AC²=AB² + BC²

AC² = 12² + 20²

AC² = 544 ⇒ √544 ⇔ 23.32 miles

The figure of the triangle is missing, so i have attached it.

Answer:

BC = 5.4

Step-by-step explanation:

From the attached triangle image, we are given 2 angles, but we need to find the third angle before we can find BC.

We know that sun of angles in a triangle is 180°.

Thus;

∠A = 180 - (∠C + ∠B)

∠A = 180 - (24 + 130)

∠A = 26°

Now, from sine rule, we can find BC.

BC/sin A = AB/sin C

Thus;

BC = (AB sin A)/sin C

BC = (5 × sin 26)/sin 24

BC = 5.389

Approximating to the nearest tenth gives;

BC = 5.4
