3/7•d=9/14 in this Problem you want to find what d equals

1 answer:

7 0

→ Chapter : Fractions ←
≡ We know that:
⇔ $(\frac{a}{b}) \div (\frac{c}{d})=(\frac{a}{b}) \times (\frac{d}{c})$

≡ Solution:
⇒ $(\frac{3}{7}) \times (d)=\frac{9}{14}$
⇒ $d=(\frac{9}{14}) \div (\frac{3}{7})$
⇒ $d=(\frac{9}{14}) \times (\frac{7}{3})$
∴ $\boxed{\frac{3}{2}}$

Which of the following is the equation of a line parallel to the line y = 4x + 1, passing throughout the point (5,1)?

snow_tiger [21]

The answer is A. When you put it into slope-intercept form it is the only equation that turns out parallel, and when you plug in the x value 5 you get the y value of 1, which means it passes through the point (5,1)

Find side x , give your answer 1 decimal place

Vladimir [108]

Given:

Let A denote the angle of the given triangle which measures ∠A = 81°

Let B denote the angle which measures ∠B = 40°

The length of the side a = x.

The length of the side b = 7 cm.

We need to determine the value of x.

Value of x:

The value of x can be determined using the law of sine formula.

Applying the law of sine, we have;

$\frac{sin \ A}{a}=\frac{sin \ B}{b}$

Substituting the values, we have;

$\frac{sin \ 81^{\circ}}{x}=\frac{sin \ 40^{\circ}}{7}$

Simplifying, we get;

$\frac{0.988}{x}=\frac{0.643}{7}$

Cross multiplying, we have;

$0.988 \times 7=0.643 x$

$6.916=0.643x$

$10.8=x$

Thus, the length of the side x is 10.8 cm.

Find the area of the triangle answer in digital format only

IceJOKER [234]

Answer:

Step-by-step explanation:

Assume that each cell on the grid represents one unit. One can use the formula, ( $A=\frac{(base)(hieght)}{2}$ ) to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,

$A=\frac{(11)*(6)}{2}$

$A=\frac{66}{2}$

$A=33$

Answer:

You got it right. Triangle DAC

Step-by-step explanation:

Line segment DA is a perpendicular bisector(it cuts line segment CE perfectly in half making line segment AE an CA congruent. Since the triangle share line segment DA that makes them congruent by the SAS postulate
