How you do this:

5x-2=10 you must add 2 to both sides like this 5x-2+2=10+2 you get 5x=12 now divide 5 from each side like this 5/5 x=12/5   you get x=2.4 I hope I helped!

Use right triangle ABC, with right angle C, as shown to answer the question.
kompoz [17]

The ratios are: sin B = 4/5 , cos B = 3/5 and tan B = 4/3

Step-by-step explanation:

We can see in the diagram that the values of all sides are given. In case of trigonometric ratios, the side in front of angle under consideration is perpendicular and the side adjacent to angle is base.

In the given case, we have to find trigonometric ratios for angle B; So,

Base = a = 3

Perpendicular = b = 4

Hypotenuse = c = 5

Hence,

The ratios will be:

sin\ B = \frac{perpendicular}{hypotenuse} = \frac{b}{c} =\frac{4}{5}\\cos\ B = \frac{base}{hypotenuse} = \frac{a}{c} =\frac{3}{5}\\tan\ B = \frac{perpendicular}{base} = \frac{b}{a} = \frac{4}{3}

The ratios are: sin B = 4/5 , cos B = 3/5 and tan B = 4/3

Keywords: Ratios, triangle

Jon is decorating a panner for a parade. Jon uses a piece of red ribbon witch is 3 4ths yard long. Jon also needs blue ribbon th
SVEN [57.7K]

Answer:

John needs 3\frac{3}{4}  yards of blue ribbon.

Step-by-step explanation:

We have been given that Jon uses a piece of red ribbon witch is 3/4th yard long. Jon also needs blue ribbon that is 5 times as long as the ribbon. We are asked to find the amount of blue ribbon that John needs.

To find the amount of blue ribbon that John needs, we will multiply amount of red ribbon by 5 as shown below:

\text{Amount of blue ribbon}=5\times \frac{3}{4}

\text{Amount of blue ribbon}=\frac{5\times 3}{4}

\text{Amount of blue ribbon}=\frac{15}{4}

\text{Amount of blue ribbon}=3\frac{3}{4}

Therefore, John needs 3\frac{3}{4}  yards of blue ribbon.

John has $1400 in his savings account and withdraws 2/7 of it. How much is left in his account?
Gemiola [76]

$1400 / 7 = $200

$200 x 2 = $400

$1400 - $400 = $1000

John has $1000 left in his account.

What is the equation of the parabola, in vertex form, with focus at (1,-4) and<br> directrix x= 3?
lilavasa [31]

Answer:

D.

Step-by-step explanation:

1) according to the definition of parabola d(focus)=f(directrix),

2) then

d(focus)=\sqrt{(x-1)^2+(y+4)^2} \ and \ d(directrix)=|x-3|;

\sqrt{(x-1)^2+(y+4)^2} =|x-3|;

3) after evoluation the equation:

(y+4)²=-4x+8 or (y+4)²= -4(x-2);

4) correct answer is D.
