Answer: $420
Divide 126 by .30 or 30% you do this bc if you knew the total you would multiply by .30 so instead you are doing the inverse which is division

Three streets intersect to form a right triangle as shown below. The parts of streets that make up the legs of this triangle are

Burka [1]

Answer:

70 yd.

Step-by-step explanation:

The three streets at the intersection form a right triangle.

For a right triangle, the length of the longest side (called hypothenuse) is given by Pythagorean's theorem:

$h=\sqrt{x^2+y^2}$

where

x is the length of the 1st side

y is the length of the 2nd side

h is the length of the hypothenuse

Here we want to find the hypothenuse.

We have:

x = 42 yd (length of the 1st side)

y = 56 yd (length of the 2nd side)

Substituting, we find h:

$h=\sqrt{42^2+56^2}=70 yd$

Subtract. 5/9-(3 1/3) Enter your answer, as a mixed number in simplest form, in the box.

Vaselesa [24]

Answer:

$-2\frac{7}{9}$

Step-by-step explanation:

$\frac{5}{9} - 3\frac{1}{3} = \frac{5}{9} - \frac{10}{3} = \frac{5}{9} - \frac{30}{9} = -\frac{25}{9} = -2\frac{7}{9}$

Help me , this is my homework (Geometry) . I really need help

8. Similar parts

$\dfrac{6}{18} = \dfrac{AQ}{12}$

$AQ = 12(6)/18=12/3=4$

Choice a

9. The Law of Sines says a:b:c and $\sin A : \sin B \sin C$ are the same ratio.

The sines will go in order for acute angles, we have to convert 120 to its supplement 60 and then the order is 29,31,"60" or opposite sides JK, KL, JL

choice b

10.

DEF and FEG are supplments, FEG=180-DEF=180-114=66

DEF and HEG are opposite angles, so congruent HEG=DEF=114

Concert tickets cost $15 for general admission, but only $9 with a student ID. Ticket sales total $450. Write and graph an equat

aliina [53]

The equation that models the situation is 15x + 9y = 450

The x-intercept is (30, 0) and the y-intercept is (0, 50)

Given the following parameters:

Cost of concert tickets for general admission= $15

Cost of a ticket for those with student ID = $9

Given that the total sales is $450, the equation that models this situation will be expressed as:

15x + 9y = 450

where:

x is the those that admitted generally

y are those with student ID

Get the x-intercept.

This is a point where the y-axis is zero

15x + 9y = 450

15x + 9(0) = 450

15x = 450

x = 450/15

x = 30

Thee x-intercept is (30, 0)

Get the y-intercept.

This is a point where the x-axis is zero

15(0) + 9y = 450

0 + 9y = 450

9y = 450

y = 450/9

x = 50

The y-intercept is (0, 50)
