Answer:

B. 1/7

Step-by-step explanation:

The triangles are similar, so the ratios of corresponding sides are the same.

... UV/XY = 3/21 = 1/7 . . . . . matches B

_____

When we talk about the ratio "A to B", we usually mean A:B or A/B. There's the possibility that the question could be interpreted to mean, "what factor do I multiply by to get from A to B?" In that case, the result here would be 7, because XY is 7 times the length of UV.

Plz solve question 12

skelet666 [1.2K]

Answer: C

Step-by-step explanation:

To solve for 12, we can use eliminate or substituion to solve our system of equations. Let's use elimination method.

$\left \{ {{3f-2k=10} \atop {-3f-2k=14}} \right.$

Let's add the equations together. This way, 3f+(-3f)=0

$-4k=24$ [divide both sides by -4]

$k=-6$

Now that we know k, we can plug it into either equation to find f.

$3f-2(-6)=10$ [multiply]

$3f+12=10$ [subtract both sides by 12]

$3f=-2$ [divide both sides by 3]

$f=-\frac{2}{3}$

Now that we have f and k, we know that C is the correct answer.

Which number line represents the solution to 2.5 – 1.2x < 6.5 – 3.2x?

tensa zangetsu [6.8K]

2.5 – 1.2x < 6.5 – 3.2x

-1.2x + 3.2x < 6.5 - 2.5

3.2x - 1.2x < 4

2x < 4

x < 4/2

x < 2

Answer:

$12x^2+8x+25$

Step-by-step explanation:

Given

From Figure

Sides of Triangle

$8x^2 \\4x^2+15\\8x+10$

Now, using concept

Perimeter of triangle = Sum of the sides of triangle

So,

Perimeter of triangle = $8x^2+4x^2+15+8x+10$

Adding $8x^2$ and $4x^2$ , so,

Perimeter of triangle = $12x^2+15+8x+10$

This can be written as

Perimeter of triangle = $12x^2+15+8x+10$

Adding 15 and 10,

Perimeter of triangle = $12x^2+8x+25$

So, the correct choice is = $12x^2+8x+25$

Hope this helps.

Jolie sends between 22 and 23 text messages per day. Each text message costs $0.89. Suppose Jolie's cellular bill spans a period

kondor19780726 [428]

Answer:

C. $945

Step-by-step explanation:

Cost of 1 cellular bill = (number of text msgs per day) x (cost per text msg) x (number of days in billing period)

in this case, it is given that :

cost per text msg = $0.89

number of texts per day = 22 or 23

billing cycle = 6 weeks = 6 x 7 = 42 days

hence,

Cost of 1 cellular bill = (22 or 23) x $0.89 x 42 days

if she sends 22 messages,

Cost of 1 cellular bill = (22) x $0.89 x 42 days= $822.36

if she sends 23 messages,

Cost of 1 cellular bill = (2) x $0.89 x 42 days= $859.74

if we compare thse 2 numbers that we have calculated with the choices, the closest match would be C. $945. The rest are just too far away in comparison.
