Step-by-step explanation:

Sum of angles in a quadrilateral = 360°

Sum of first 3 angles = 360° - 100° = 260°.

260° / (4 + 6 + 3) = 20°.

First angle = (20°) * 4 = 80°

Second angle = (20°) * 6 = 120°

Third angle = (20°) * 3 = 60°

The angles are 80°, 120° and 60°.

Answer:

Let the angles of the quadrilateral be 4x, 6x, and 3x

Sum of the interior angles of a quadrilateral is 360°.

According to the above problem,

[tex]4x + 6x + 3x + 100 = 360 \\ 13x = 360 - 100 \\ 13x = 260 \\ \boxed{x = 20}[/tex]

Hence, the other three angles are 80°, 120° and 60°.

Answer:

The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

Step-by-step explanation:

Given the point

(7, -7)

Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate

Therefore, the translation rule:

(x, y) → (x+3, y-1)

In our case, let the point P(7, -7)

P(7, -7)  → P'(7+3, -7-1) → P'(10, -8)

FOLLOWED BY A reflection over the x-axis

We know that the rule of reflection over the x-axis implies that

(x y) → (x, -y)

i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.

After the first transformation, we had got P'(10, -8)

so

P'(10, -8) → P''(10, -(-8)) → P''(10, 8)

Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

Answer:

11.52 miles

Step-by-step explanation:

We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.

Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles

So  L = Ф/360 × 2πR

= (1/6)°/360 × 2π(3960 miles)

= 1/2160 × 7920π

= 3.67π

= 11.52 miles

Answer:

0.9968

Step-by-step explanation:

Given that:

P of being correct = 0.5 (since there are only 2 options in each question with only one bring correct).

1 - p = 1 - 0.5 = 0.5

Number of questions, n = 12

Probability that atleast 2 questions are correct

P(x ≥ 2) = p(x = 2) + p(x = 3) +... + p(x = 12)

P(x =x) = nCx * p^x * (1 - p)^(n - x)

The sun of the individual probabilities gives us the answer or we could use the binomial probability calculator :

Hence,

P(x ≥ 2) = 0.9968

Answer:

(0,4) , (1,7) , (2,10) and (-1,1)

Step-by-step explanation:

Since you did not supply a graph, maybe I could give you some points that you should find the line on the correct graph goes through.

y = 3(0) + 4

y = 4

y = 3(1) + 4

y = 7

y = 3(2) + 4

y = 10

y = 3(-1) + 4

y = 1

The points (0,4) , (1,7) , (2,10) and (-1,1) should be on the line of the correct graph. In general, your graph should be of a straight line that crosses the y-axis at 4.

The number of days to repair 8 km of road is given by the equation A = 32 days

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the number of days to repair 8 km be represented as A

Now , the proportion will be

Let the distance be = 1250 meters = 1.250 km

The number of days to repair 1.250 km is = 5 days

Substituting the values in the equation , we get

5 / 1.250 = A / 8

Multiply by 8 on both sides of the equation , we get

A = ( 8 x 5 ) / 1.25

A = 40 / 1.25

A = 32 days

Hence , the number of days is 32 days

Answer: 2 1/2 cups of flour  will make 1 Loaf of bread.

Step-by-step explanation:

3 loafs of bread can be made from  71/2 cups of flour

1 Loaf of  bread  will require = x cups of flour

By cross multiplication , we have

(1 Loaf of  bread x 71/2 cups of flour) = 3 loafs of bread X x cups of flour

x cups of flour = (1 Loaf of  bread x 71/2 cups of flour)/ 3 loafs of bread

=15/2 X 1/3 = 5/2 = 2 1/2

OR  

7.5 /3  =2.5 = 2 1/2 cups of flour

Answer:

20 % of n would be 12.8

Step-by-step explanation:

By first finding that 24.32 is 38% of 64. To find that you would have the fractions 38/100 = 24.32/n. From there you cross multiply the 100 times 24.32 then divide that answer by 38 to get the answer 64. you take that n=64 and find 20% of that which is 12.8.

The 20% of n is 12.8

38% of number n is given as:

[tex]38\% \times n = 24.32[/tex]

Express the percentage (38%) as decimal

[tex]0.38 \times n = 24.32[/tex]

Divide both sides of the equation by 0.38

[tex]n = 64[/tex]

Multiply both sides of the equation by 20%

[tex]20\% \times n = 20\% \times 64[/tex]

Express the percentage (20%) as decimal

[tex]20\% \times n = 0.20 \times 64[/tex]

Evaluate the product

[tex]20\% \times n = 12.8[/tex]

Hence, the 20% of n is 12.8

Answer:

520

Step-by-step explanation:

When rounding to the nearest ten, like I did with 524 above, we use the following rules:

A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.

B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.

C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
