Answer:

C.

Step-by-step explanation:

1   -3

2   -5

3   -7

4   -9

Because it has a constant slope it is increasing x by 1 and decreasing y by -2.

Slope: -2/1 or -2x

Answer:

I think its the first table.

Step-by-step explanation:

My reasoning behind this is because all of the Y values are being multiplied by 2 each times.

Answer:

8.48%

Step-by-step explanation:

Bill's weight decreases from 64.8 kg to 59.3 kg.

We need to find the percentage decrease in Bill's weight. It can be calculated as follows :

[tex]\%=\dfrac{64.8 -59.3 }{64.8 }\times 100\\\\=8.48\%[/tex]

So, the required decrease in percentage is 8.48%.

Answer:

Mrs. grub bought total number of shirts = 1

Mrs. grub bought total number of hats = 8

Step-by-step explanation:

Let Mrs. grub bought total number of shirts = x

Let Mrs. grub bought total number of hats = y

As given,

Price of 1 shirt = $4

Price of 1 hat = $12

⇒ Price of x shirts = $ 4x

   Price of y hats = $ 12y

Given that,

Mrs. Grubb bought total piece of clothes = 9

⇒ x + y = 9     .......(1)

Also given,

She bought all clothing for $100

⇒ 4x + 12 y = 100       ........(2)

Divide equation (2) by 4 we get

x + 3y = 25     .......(3)

Now,

Subtract equation (1) from equation (3) , we get

x + 3y  - ( x + y ) = 25 - 9

⇒ x + 3y - x - y = 16

⇒2y = 16

⇒y = [tex]\frac{16}{2}[/tex] = 8

⇒ y = 8

Put value of y in equation (3), we get

x + 3(8) = 25

⇒x + 24 = 25

⇒x = 25 - 24 = 1

⇒x = 1

∴ we get

Mrs. grub bought total number of shirts = x = 1

Mrs. grub bought total number of hats = y = 8

Answer:

17.7cm  (1.d.p)

Step-by-step explanation:

First do [tex]16^{2}[/tex] (16 x 16) add [tex]7.5^{2}[/tex] (7.5x7.5)

That gives us 312.25 cm

Then find the square root of that [tex]\sqrt{312.25[/tex]

That equals 17.67059705

If you do it to one decimal place, [tex]x^[/tex] is 17.7cm

Answer:

A = -28

B = -22

C = -13

D = -4

E = 2

Step-by-step explanation:

Answer:

A = -21

B = -19

C = -13

D = -7

E = -4

Step-by-step explanation:

Looking at the only two numbers provided, and that one space between them, we can only assume that they're being increased by 3. :

-16 + 3 = C

-16 + 3 = -13

-13 + 3 = -10

So we can do the same for all answers except A and B because they're before -16. Instead for A and B, we subtract 3 because they're before -16.

-16 - 3 = B = -19

-19 - 3 = A = -21

-10 + 3 = D = -7

-7 + 3 = E = -4

-21 , -19 , -16 , -13 , -10 , -7 , -4

A      B               C             D   E

Answer:

9.3 inches

Step-by-step explanation:

Average rainfall = total rainfall / number of days

0.31 = total rainfall / 30

total rainfall = 0.31 x 30 = 9.3 inches

Answer:

$479.15

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9.25%/100 = 0.0925 per year,

then, solving our equation

I = 1295 × 0.0925 × 4 = 479.15

I = $ 479.15

The simple interest accumulated

on a principal of $ 1,295.00

at a rate of 9.25% per year

for 4 years is $ 479.15.

Answer:

15cm by 20cm by 25cm

Step-by-step explanation:

Let the sides of the right angle be x, y and h

x is the breadth

y is the height

h is the hypotenuse

Perimeter = x + y + h

x + y +h  = 60

x+y = 60-h .... 1

If its area is equal to 150 square cm, then;

Area = 1/2 * base * height

Area = 1/2 *x * y

xy/2 = 150

xy = 300 ....2

According to pythagoras theorem;

x² + y² = h²

On expanding x² + y²

x² + y² = (x+y)² - 2xy

The equation becomes

(x+y)² - 2xy = h² ... 3

Substitute equation 1 and 2 into 3;

From 3;

(x+y)² - 2xy = h² ... 3

(60-h)² - 2(300) = h²

3600-120h + h² - 600 = h²

3600-120h - 600 = 0

-120h = 600-3600

-120h = -3000

h = 3000/120

h = 25cm

Recall that x+y+h = 60

x+y+25 = 60

x+y = 60 - 25

x+y = 35 ... 4

From equation 2;

xy = 300

x = 300/y ..... 5

Substitute 5 into 4;

300/y + y = 35

(300+y²)/y = 35

300+y² = 35y

y²-35y + 300 = 0

y²-20y-15y + 300 = 0

y(y-20)-15(y-20) = 0

y-20 = 0 and y - 15 =0

y = 20 and 15

since x+y = 35

x + 20 = 35

x = 35 - 20

x = 15

Hence the sides of the triangle are 15cm by 20cm by 25cm

Answer:

A: SSS | B: HL | C: SAS

Step-by-step explanation:

Firstly, SSS is where you know that each side of a triangle is congruent to the other triangle.

Secondly, SAS is where you know two sides and an angle are congruent. This angle will be between two sides that are congruent. This can be put clockwise or counterclockwise, but the sides and angle must be consecutive.

Thirdly, AAS is where you know two angles and one side are congruent.

Lastly, HL (Theorem) is where you know that the hypotenuse and a leg of a right triangle are congruent.

A: TU≅WX, ST≅XV, and SU≅VW
