Here’s an update someone helped me get this and it didn’t work

Mathematics
1 answer:
AfilCa [17]3 years ago
5 0

Answer:

Left side

Ca(OH)2 --> Ca + 2 O + 2 H

2 HBr --> 2 H + 2 Br

Together: Ca + 2 O + 4 H + 2 Br

You have only 1 Br and only 3 H. So you must correct this.

Jason is building a 1 : 180 scale model of a real castle. his model has a rectangular base that is 3 feet wide and 4 feet long.w
balu736 [363]
The area of the actual castle would be 388,800 sq. ft.

We would multiply each of the sides of the scale model both by 180 to find the side lengths of the actual castle.

So...
180 x 4 = 720
180 x 3 = 540

If Area is equal to Length Times Width, all thats left to do is to multiply the two sides together.

720 x 540 = 388,800

Hope this helped! :D

Which of the following does not preserve orientation.
Murljashka [212]
Translations move the pre-image horizontally or vertically, but retain its orientation.

Reflections reflect across axes, mirroring the pre-image. Reflections result in a change of orientation.

Dilations stretch or shrink the pre-image by a scale factor; they change the pre-image's size but retain the pre-image's orientation.

Rotations rotate around a center point, but don't change the direction of the shape (its orientation).

Answer:
g. reflections

what is the center and radius of the circle given the equation, 8x + x-squared - 2y + y-squared - 64 = 0?
RoseWind [281]

Step-by-step explanation:

8x + x² - 2y + y² - 64 = 0

(x + 4)² + (y - 1)² - 81 = 0

(x + 4)² + (y - 1)² = 81

Hencr the center is (-4,1) and the radius is 9.

One third of the students at the STEM Academy play sports. Two fifth of the students who play sports are girls. What fraction of
andreyandreev [35.5K]

Answer:

2/15

Step-by-step explanation:

If we have that one third of the students play sports, and two fifth of the students who play sports are girls, to find the fraction of all students that are girls and play sports, we just need to multiply both fractions, because the subset of girls who play sports in relation to the total number of students that play sports is inside the set of total number of students that play sports in relation to the total number of students:

So the fraction of students that are girls who play sports is:

(1/3) * (2/5) = 2/15
