the width is 39 in

Step-by-step explanation:

length is 52. there are two "length" sides witch = 104

the perimiter is all sides added. 182-104= 78

78= both of the width sides so 78 divide by 2 = 39in

Find a ⋅ b. a = <5, 2>, b = <4, 5>

cestrela7 [59]

Answer:

Step-by-step explanation:

For a = <xa, ya> and b = <xb, yb>, the dot product is the sum of products ...

a·b = (xa)(xb) + (ya)(yb)

Substituting the given information, you have ...

a·b = 5·4 + 2·5 = 20 + 10

a·b = 30

_____

Some graphing calculators can do such math. There are also dot product calculators available on the Internet. If you have quite a few of these to calculate, you can put the appropriate formula into a spreadsheet.

Answer:

$x > - \frac{1}{3}$

Step-by-step explanation:

$9(2 - x) - 4(2 - 3x) > 9$

$18 - 9x - 8 + 12x > 9$

$10 + 3x > 9$

$3x > 9 - 10$

$3x > - 1$

To reach a vacation spot, the Jones family first traveled by plane and then drove the

navik [9.2K]

The distance flown by plane is 750 kilometers.

Step-by-step explanation:

Let,

Distance traveled by plane = x

Distance traveled by car = y

Total distance = x+y

According to given statement;

The distance by car was 125 kilometers less than the distance by plane.

y = x - 125 => x=y+125 Eqn 1

The total distance was 500 kilometers less than three times the distance traveled by car.

Total distance = 3y - 500

x+y=3y-500 Eqn 2

Putting value of x from Eqn 1;

$(y+125)+y=3y-500\\y+y+125=3y-500\\2y=3y-500-125\\2y-3y=-625\\-y=-625\\y=625$

Putting y=625 in Eqn 1

$x=625+125\\x=750$

The distance flown by plane is 750 kilometers.

If 5/6 gallons of paint covers 1/4 of the house, then how much paint is needed for the entire house?

tia_tia [17]

Answer:

Step-by-step explanation:

1) If $\frac{5}{6}$ is needed to cover $\frac{1}{4}$ than we need 3 more: $\frac{5}{6}(3)=\frac{15}{6} =2\frac{3}{6} gallons2) But we still need to add the beginning [tex]\frac{5}{6}$ : $2\frac{3}{6}+\frac{5}{6}=2\frac{9}{6}=3\frac{3}6}=3.5$
