Answer: x = 2

Step-by-step explanation:

The slope of a vertical line is undefined, so the equation of a vertical line is x = a

In this problem, the only choice that represents a vertical line is x = 2 (where a = 2)

Find the number of distinct triangles with measurements of A=31°, a = 10, and b = 40 A. 0 B. 1 C. 2 D. cannot be determined Plea

Inessa [10]

Answer: A. 0 <------

Step-by-step explanation:

Law of Sines

sinA / a = sinB / b

sin31 / 10 = sinB/ 40

sinB = 40sin31 / 10

sinB = 2.060152299640217

Since 1 is the maximum for sin

the triangle does not exist

The scale used for a model of a kitchen is 1/4 in. = 1.5 ft. In the model,

fgiga [73]

Answer:

15ft by 18ft

Step-by-step explanation:

Start with 2.5 divided by .25

That equals 10

10 times 1.5 ,because we know it takes ten .25inches to equal 2.5 and 2.5, is the size of one of the sides.

10 time 1.5 is 15ft

3 divided by .25 is 12

using the same logic and math as stated above we know 3 x .25 equals 12 by 12 quarter inches to make 3 inches

12 x 1.5 Same logic as before

12 x 1.5 equals 18ft

The kitchen is 15ft by 18ft

zzz [600]

Answer:

Mary is 8 and that Zane and Chase are both 4 years old.

Step-by-step explanation:

For this equation, we will say Mary = M, Zane = Z, and Chase = C.

We will now convert the word problem into equations.

$2m = z, 2c - 4 = z, c = 4$

Now I will solve the equations by putting C into the equation.

$2(4) = 8, 2(4) - 4 = 4, c = 4$

So we can see that Mary is 8 and that Zane and Chase are both 4 years old.

Can someone solve for me pls!!!!!

g100num [7]

Answer:

$\frac{7}{15}$

Step-by-step explanation:

Let 1 unit be 0.4666...

16 units = $0.4666...*16=7.4666...$

15 units = $7.4666...-0.4666...$

15 units = $7$

1 unit = $\frac{7}{15}$
