Answer:

(1) 25.5 meters square

(2) 1.5 hours

Step-by-step explanation:

(1) Tucker painted 2/3 of his deck before lunch so he has 1/3 of the deck to paint after lunch.(1 - 2/3). So you do 1/3 of of the deck (76 1/2 meters square) to paint. 1/3 x 76 1/2 is 25 1/2 meters square. 25 1/2 is 25.5.

(2) This is like the last problem just with different numbers. She has 3/5 of 2 1/2 hours left. So you times 3/5 by 2 1/2. You get 1 1/12 which is 1.5.

In triangle bcd if bc =bd angle b = 13x-35 angle c =5x-19 and angled d = 2x+14 find x and the measure of each angle

MakcuM [25]

Answer:

<b = 108 degrees

<c = 36 degrees

<d = 36 degrees

Step-by-step explanation:

The sum of angle in a triangle is 180 degrees

Hence <b + <c + <d = 180

13x-35 + 5x - 19 + 2x + 14 = 180

13x+5x+2x-35-19+14 = 180

20x-40 = 180

20x = 180 + 40

20 x = 220

x = 220/20

x = 11

Get <b

<b = 13x-35

<b = 13(11) - 35

<b = 143-35

<b = 108 degrees

Get <c

c =5x-19

<c = 5(11)-19

<c = 55-19

<c = 36degrees

Get <d

<d = 2x+14

<d = 2(11) + 14

<d = 22+14

<d = 36 degrees

A bowl contains blueberries and strawberries there are a total of 20 bares in the bowl the ratio blueberries to strawberries is

Alexus [3.1K]

Answer:

16 blueberries and 4 strawberries

Step-by-step explanation:

Given:

A bowl contains blueberries and strawberries there are a total of 20 berries in the bowl.

The ratio blueberries to strawberries is 4 to 1

Question asked:

How many of each berry are in the bowl ?

Solution:

Ratio of blueberries and strawberries = 4 : 1

Let ratio be $x$

Number of blueberries in the bowl = $4x$

Number of strawberries in the bowl = $1x=x$

As total berries in the bowl are 20 and the bowl contains both blueberries and strawberries in the ratio 4 : 1 :-

$4x+x=20\\5x=20\\$

Dividing both sides by 5

$x=4$

Number of strawberries in the bowl = $x$ = 4

Number of blueberries in the bowl = $4x$ = $4\times4=16$

Thus, there are 16 blueberries and 4 strawberries in the bowl.

The equation y+6=1/3(x-9) is written in point-slope form. What is the equation written in slope-intercept form?

loris [4]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y + 6 = $\frac{1}{3}$ (x - 9) ← distribute the parenthesis

y + 6 = $\frac{1}{3}$ x - 3 ← subtract 6 from both sides

y = $\frac{1}{3}$ x - 9 ← in slope- intercept form
