Answer you multiple it by 10
Step-by-step explanation:
The height of the heater is about 89.3 in.
You can solve this problem with the Pythagorean Theorem. The base is a square. So half way across the middle will the right under the tip of the pyramid. We can use the measurement with the slant height to write and solve the equation below.
23.8^2 + x^2 = 90.1^2
x will be about 89.3.
Answer:

Step-by-step explanation:
let's firstly convert the mixed fractions to improper fractions and then multiply across.
![\bf \stackrel{mixed}{1\frac{8}{10}}\implies \cfrac{1\cdot 10+8}{10}\implies \stackrel{improper}{\cfrac{18}{10}\implies \cfrac{9}{5}}~\hfill \stackrel{mixed}{5\frac{1}{2}}\implies \cfrac{5\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{11}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{9}{5}\cdot \cfrac{11}{2}\implies \cfrac{9\cdot 11}{5\cdot 2}\implies \cfrac{99}{10}\implies 9\frac{9}{10}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7Bmixed%7D%7B1%5Cfrac%7B8%7D%7B10%7D%7D%5Cimplies%20%5Ccfrac%7B1%5Ccdot%2010%2B8%7D%7B10%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B18%7D%7B10%7D%5Cimplies%20%5Ccfrac%7B9%7D%7B5%7D%7D~%5Chfill%20%5Cstackrel%7Bmixed%7D%7B5%5Cfrac%7B1%7D%7B2%7D%7D%5Cimplies%20%5Ccfrac%7B5%5Ccdot%202%2B1%7D%7B2%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B11%7D%7B2%7D%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20%5Ccfrac%7B9%7D%7B5%7D%5Ccdot%20%5Ccfrac%7B11%7D%7B2%7D%5Cimplies%20%5Ccfrac%7B9%5Ccdot%2011%7D%7B5%5Ccdot%202%7D%5Cimplies%20%5Ccfrac%7B99%7D%7B10%7D%5Cimplies%209%5Cfrac%7B9%7D%7B10%7D)
Substitute y in second equation
-5x-(4x+6)=21
-9x-6=21
9x+6=-21
9x=-27
X=-3
Solve for y:
Y=4(-3)+6
Y=-6
