What is the slope of a line that
crosses through the points (-1,-8)
and (2, 1)?

Answer:

|QR| = 17.6

Step-by-step explanation:

To answer this we need to show that the triangles are similar or to assume that they are similar.

Note the following:

1.  The ratio of the longest sides is 12.5 to 25.0, or 1/2;

2.  The ratio of the shortest sides is 5.2 to 10.4, or 1/2

Therefore the ratio of the longer legs is 8.8 to QR, also equal to 1/2

 8.8        1

-------- = -----

  QR       2

Cross-multiplying, we get |QR| = 17.6

Answer:

[tex] \displaystyle B )\overline{ \text{QR }}= 17.6 cm[/tex]

Step-by-step explanation:

we have two similar triangles

we want to figure out the measure of QR

remember that,

the ratio of the corresponding sides of two similar triangles is equal

thus,

[tex] \displaystyle \frac{8 .8}{QR} = \frac{5.2}{10.4} [/tex]

cross multiplication:

[tex] \displaystyle5.2 QR = 91.52[/tex]

divide both sides by 5.2:

[tex] \displaystyle \frac{5.2 QR }{5.2}= \frac{ 9 1.52}{5.2}[/tex]

simplify division:

[tex] \displaystyle QR = 17.6 cm[/tex]

hence, our answer is B

Answer:

a)3/4

b)5/8

Step-by-step explanation:

a)2 1/4x (1-2/3)=9/4 x1/3=3/4

b)3/4-1/8=6/8-1/8=5/8

Answer:

x=6 degrees

Step-by-step explanation:

I know that 31+(10x-1)=90. Then I have to subtract 31 from 90 to get 10x -1.

That's 59. I solve for x in the equation 59=10x-1.

That is the same thing as 60=10x, which is also the same as 6=x.

Complete question :

One gallon of gasoline in buffalo, New York costs $2.29. In Toronto, Canada, one liter of gas costs $0.91. There are 3.8 liters in one gallon. How much does one gallon of gas cost in Toronto?

Answer:

$3.458

Step-by-step explanation:

Given that :

Cost per gallon in Buffalo, New York = $2.29

Cost per Litre in Toronto, Canada = $0.91

Number of litres in 1 gallon = 3.8

The cost per gallon in Toronto, Canada will be :

3.8 * cost of a Litre

3.8 * $0.91 = $3.458

Hence, cost of a gallon in Toronto, Canada = $2.73

Answer:

u ≤ 2

Step-by-step explanation:

Given

- 10 ≤ - 5u

Divide both sides by - 5 , reversing the symbol as a result of dividing by a negative quantity.

2 ≥ u , then

u ≤ 2

Answer:

17 5/6 is the answer.

Step-by-step explanation:

6+5+5=16 + 2/3+5/6+1/3

2/3=4/6

1/3=2/6

2+4+5=11/6=1 5/6

1 5/6+ 16=17 5/6

Answer: 4 in

Step-by-step explanation:

The volume of the cylinder is

[tex]V=(\pi)(2^{2})(3)=12\pi[/tex]

If we let the height of the cone h, the volume of the cone is

[tex]V=\frac{1}{3}(\pi)(3^{2})(h)=3\pi h[/tex]

Setting these volumes equal,

[tex]12\pi=3\pi h\\\\12=3h\\\\h=\boxed{4 \text{ in}}[/tex]

F(x) represents the zeros of the given quadratic function. i.e. the linear factors represents zero when we resolve the expression

Step-by-step explanation:

Describing the relationship between the zeros of the quadratic function and the linear factors of the expression using an example as shown below

lets describe this using the example below :

quadratic expression  : F(x) = ax^2 + bx + c

let the linear factors of  F( x ) = 0

F(x) represents the zeros of the given quadratic function above i.e. the linear factors represents zero when we resolve the expression
