Let's understand the concept:-Here angle B is 90°
So [tex]\triangle ABC[/tex] and [tex]\triangle ABD [/tex] Are right angled triangle
So we use Pythagoras thereon for solution
Required Answer:-First in triangle ABCperpendicular=p=8cm
Hypontenuse =h =10cm
We need to find base=bAccording to Pythagoras thereon
[tex]{\boxed{\sf b^2=h^2-p^2}}[/tex]
Substitutethe values[tex]\longrightarrow[/tex][tex]\sf b^2=10^2-p^2[/tex]
[tex]\longrightarrow[/tex][tex]\sf b={\sqrt {10^2-8^2}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf b={\sqrt{100-64}}[/tex]
[tex]\longrightarrow[/tex][tex]\bf b={\sqrt {36}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf b=6[/tex]
[tex]\therefore[/tex][tex]\overline{BC}=6cm[/tex]
BD=BC+CD[tex]\longrightarrow[/tex][tex]BD=9+6[/tex]
[tex]\longrightarrow[/tex][tex]BD=15cm [/tex]
Now in [tex]\triangle ABD [/tex]Perpendicular=p=8cm
Base =b=15cm
We need to find Hypontenuse =AD(x)According to Pythagoras thereon
[tex]{\boxed {\sf h^2=p^2+b^2}}[/tex]
Substitute the values[tex]\longrightarrow[/tex][tex]\sf h^2=8^2+15^2 [/tex]
[tex]\longrightarrow[/tex][tex]\sf h={\sqrt {8^2+15^2}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf h={\sqrt {64+225}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf h={\sqrt {289}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf h=17cm [/tex]
[tex]\therefore[/tex][tex]{\underline{\boxed{\bf x=17cm}}}[/tex]

10 bags of chips and 8 soda cans cost $15. 5 bags of chips and 5 soda cans cost $8. How much does a bag of chips cost? How much does a can of soda cost?
Answers
Answer:
One bag of chips costs $1.10
One can of soda costs $0.50
Step-by-step explanation:
1. Create a system of equations (b = bags of chips | s = soda)
10b + 8b = 15
5b + 5s = 8
2. Use the Elimination method by multiplying 5b+5s=8 by -2
10b + 8b = 15
-2(5b + 5s = 8)
=
10b + 8b = 15
- 10b - 10s = -16
(10b and -10b will cancel out, so you will only have s left)
=
-2s = -1
Divide by 2
Soda = 1/2, or $0.50
3. Plug in S (0.50) into an equation above and get B by itself
5b + 5(0.50) = 8
=
5b + 2.5 = 8
- 2.5 -2.5
5b = 5.5
Bag of Chips = $1.10

what is the product of 25 and (6/5n +31/4)

30n + 193.75
Step-by-step explanation:
Product means multiplication so 25([tex]\frac{6}{5}n +\frac{31}{4}[/tex])
The first step is distribution of 25 to all numbers in ( ).
25([tex]\frac{6}{5}n[/tex]) is 30 and 25([tex]\frac{31}{4}[/tex]) is 193.75
Now we have the equation 30n + 193.75 which cannot be simplified further since the two variables are not like terms.

1. Sharon and Geordi both worked hard over the summer. Together they earned a total of $525. Geordi earned $75 more than Sharon.
(a) Write a system of equations for the situation. Use s for the amount Sharon earned and g for the amount Geordi earned.
(b) Graph the equations of the system on the graph provided
Answers
Answer:
s + g = 575
g = 75 + s
g = 325
s = 250
Step-by-step explanation:
Given that :
Total amount earned by Sharon and Geordi = $525
Also, Geordi earned $75 more than Sharon
Let amount earned by Sharon = s
Amount earned by Geordi = g
Equations :
s + g = 575 - - - equation 1
g = 75 + s - - - equation 2
Put g = 75 + s in equation 1
s + 75 + s = 575
2s + 75 = 575
2s = 575 - 75
2s = 500
s = 250
g = 75 + s
g = 75 + 250
g = 325

For every cup of milk, we use 4 cups of flour. Write a linear equation to represent the relationship.
Answers
So, for every cup of milk we have 4 cups of flour.
We can also wright this as M= 4F
When we have one M (cup of milk) it must be equal to 4F (cups of flour),
For every one M we have 4F.
We can replace M and F with X and Y. They still mean the same thing, we just often see expressions written with X and Y in math.
So,
y=4x
Your class collected money to buy turkeys and hams for
the local food shelter. After the collection, your class
had exactly enough money to buy 11 hams and 9
turkeys. If you raised a total of $316, and each turkey
cost $18, how much is one ham?
Answers
Answer: $14.00
Step-by-step explanation:
9 turkeys costed a total amount of $162.00
We need to subtract that from the total cost, $316.00, to find out how much money was spent on 11 hams.
316 - 162 = 154
So, 11 hams costed 154.
We then need to find the unit rate of 11 turkeys for 154 dollars.
To do that, we must divide 154 ÷ 11
That gives us 14.
Therefore, your answer is: $14.00 per ham.

slope of y = 7x-100
Answers
Answer:
The slope equals 7.
Step-by-step explanation:
Following the formula y = mx + b where:
m = slope
x = independent variable
b = y-intercept
our equation looks like:
y= 7x - 100
m = 7
x = x
b = -100
If slope = m and m = 7 then we can conclude that the slope = 7.
Probability of rolling a composite number on a dice and the coin landing on tails
Answer choices are 1/8, 2/3 and 5/6
This is 7th grade math btw
Answers
Answer:
5/6.
Step-by-step explanation:
The only composite numbers on a die are 4 and 6, so the probability of landing on them is 2/6 or 1/3. The probability of landing on tails on a coin is 1/2. Add them together (1/3 + 1/2) and you get the total probability of 5/6.
