<h3>Answer 1a :- </h3>

Here we can solve this question using<em> </em><em>Unitary</em><em> </em><em>Method</em><em> </em><em>.</em> As ;

→ In 17hrs the boat travels 452km

→ In 1hr the boat will travel 452km/17

→ In 9hrs the boat will travel 452/17km * 9 = 239.29km

$\rule{200}4$

<h3>Answer 1b:-</h3>

→ A car can travel 156km on 13L gasoline .

→ It will travel 1km on 13/156L of gasoline .

→ It will travel 480km on 13/156*480L = 40L of gasoline .

$\rule{200}4$

<h3>Answer 2a :-</h3>

→ A boat can go 180 miles on 60L gasoline.

→ It will go 1mile in 60/180L of gasoline.

→ It will go 306 miles in 60/180*306L = 102L of gasoline .

$\rule{200}4$

<h3>Answer 2b :-</h3>

→ On 51L of gasoline a car can go 408km

→ On 1L of gasoline car will go 408/51 km

→ On 11L of gasoline it will go 408/51*11L = 88km

$\rule{200}4$

WHAT ARE CONGRUENCE LINES

Sergeeva-Olga [200]

Answer:

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. ... Rays and lines cannot be congruent because they do not have both end points defined, and so have no definite length.

ElenaW [278]

Answer: 3.61km or √13

Step-by-step explanation:

Given Data:

Sides of hexagon = 2km each

Distance walked by Ama = 5km

Therefore;

Let Ama starting position be the origin.

With this She would travel along two edges and then go halfway along a third.

Her new x- coordinate would be

= 1 + 2 + 1/2 = 7/2

Because she travels a distance of 5km which translates to 2 and half side of the Hexagon

= 2*1/2

= 1km. On her x-coordinates

For her y-coordinate we use same principles as x-coordinates

= √3 + 0 - √3/2

= √3/2

Therefore her distance walked

= √ ( (7/2)^2 + (√ 3/2)^2 )

= √ ( 49/4 + 3/4 )

= √ 13

= 3.61km

Garcia's Grill offers 77 side dishes, 55 types of steak, and 88 toppings. How many different smothered steak dinners can be made

svet-max [94.6K]

Answer:

Therefore the total number of ways that the customer can order the smothered steak dinner is 9800.

Step-by-step explanation:

There are 7 side dishes, and types of stake and 8 toppings.

The customer will have a smothered steak dinner.

The smothered steak dinner will consist of steak and 3 different toppings and 4 $\binom{8}{3} = \frac{8!}{3! \times 5!} = 56$ different side dishes.

The number of ways steak can be selected is = $\binom{5}{1} = \frac{5!}{1! 4!} =5$

The number of ways toppings can be chosen is = $\binom{8}{3} = \frac{8!}{3! 5!} = 56$

The number of ways side dishes can be chosen = $\binom{7}{4} = \frac{7!}{4!3!} = 35.$

Therefore the total number of ways that the customer can order the smothered steak dinner is

= 5 × 56 × 35 = 9800.

If LM=41-2x and NP=7x+5, find LM

Tatiana [17]

Answer:
LM = 33 units

Explanation:
From the drawing:
LM = NP
41 - 2x = 7x + 5
41 - 5 = 7x + 2x
36 = 9x
x = 9

This means that:
LM = 41 - 2x
LM = 41 - 2(4)
LM = 33 units

Hope this helps :)

Answer:

rom the relation for linear regression formula, Y = b·X + a, we have ;

For car 1

ΣXY = 102780

(ΣX)² = 36

ΣX = 6

ΣY = 52390

ΣX² = 14

N = 3

b = -1000

a = 19463

Y = -1000×X + 19463

For Car 2

ΣXY = 102539.8

(ΣX)² = 36

ΣX = 6

ΣY = 52346.6

ΣX² = 14

N = 3 .

b = -1076.7

a = 19602

Y = -1076.7×X + 19602
