what is the value of x.
Answer:
x=47
Step-by-step explanation:
180-121=59
180-(59+74)=47
Answer:
x = 47
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
121° is an exterior angle of the triangle, then
x + 74 = 121 ( subtract 74 from both sides )
x = 47
Fred drew 2/3 on a number line. Sara broke her number line into 6 equal pieces but found the same fraction on the number line as Fred. What fraction did Sara make?
Answer:
4 / 6
Step-by-step explanation:
Fred fraction = 2/3
Sarah formed a fraction by dividing her number line into 6 equal pieces. This is given as;
x / 6
Since her fraction is equal to that of fred, we have;
x / 6 = 2 / 3
x = 6 * 2 / 3 = 4
Sarah Fraction = 4 / 6

Raju bought an old car for Rs.125000 and spent Rs.25000 on its repair . He sold the car for Rs.200000 . Find his gain or loss percent .
Answer: [tex]33.33\%[/tex]
Step-by-step explanation:
Given
Raju buy an old car for [tex]Rs\ 1,25,000[/tex]
He spent [tex]Rs\ 25000[/tex] on its repair
The selling price of the car [tex]Rs\ 2,00,000[/tex]
So, the cost price is
[tex]\Rightarrow C.P.=1,25,000+25,000=Rs\ 1,50,000[/tex]
Here, [tex]S.P.> C.P.\quad \text{i.e. gain}[/tex]
Gain percent is
[tex]\Rightarrow \text{Gain percent}=\dfrac{2,00,000-1,50,000}{1,50,000}\times 100=\dfrac{50,000}{1,50,000}\times 100\\\Rightarrow \text{Gain percent}=33.33\ \%[/tex]
28.In the year 2006, the number of malaria patients admitted in the hospital of a state was 4375. Every year this number decreases by 8%. Find the number of patients in the year 2008?
Answer:number of patients in the year 2008 =3,703 Patients.
Step-by-step explanation:
Number of malaria patients admitted in the hospital of a state in 2006= 4375.
Number of malaria patients admitted in the hospital of a state in 2007 if there was Decrease by 8% in 2007
= 8% x 4375 =350
4375-350=4,025 patients
Number of malaria patients admitted in the hospital of a state in 2008 since there was Decrease by 8% in 2008
8% x 4,025.= 322
4,025-322=3,703 Patients.

Find the area of the composite shape below.
Answer: 1106.13 (2 decimal places)
Step-by-step explanation:
To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.
The formula for the area of a circle is πr^2 (pi x radius squared).
So when you put the numbers in the formula the area is πx11^2=380.1327111
Then to work out the area of the rectangle you would do base x height.
The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.
To find the area of the rectangle you do 22x33=726
So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.
726+380.1327111=1106.13 (2 decimal places).

You are helping your family run a store and decide to mark up the items you are selling for a profit by 35%. An item you want to sell in the store cost $4.38 from the warehouse. If you apply the 35% mark up, what will be the sale price of the item in your store. (Round to the nearest cent)
Answer: $6
Step-by-step explanation:
Cost of item = $4.38
Mark up percent = 35%
Sakes price will be the addition of the cost price and the mark up price. This will be;
= $4.38 + (35% × $4.38)
= $4.38 + (0.35 × $4.38)
= $4.38 + $1.533
= $5.913
= $6 approximately

Algebra.
Answer:
3. -3
4. 4
Step-by-step explanation:
3 . so [tex]h^{2} = g^{?+3} h^{2}[/tex], we cancel the [tex]h^{2}[/tex] out and it leaves us with [tex]1=g^{?+3}[/tex]
Which means ?+3=0, and ?=-3
4. so [tex]k^{?} = k^{4}[/tex], ?=4

A jar contains 660 beans. Of them, 440 are kidney beans and the rest are cranberry
beans. What is the ratio of kidney beans to all beans?
Answer:
Step-by-step explanation:
kidney beans : all beans
440:660 (simplify by dividing each by gcf which is 2^2(5)11=220)
2:3
Answer:
440:660 OR Simplified 2:3
Step-by-step explanation:
You already had the two numbers for the ratio, they added the cranberry beans in the sentence like that to confuse you and draw you away from the real answer. All you needed to do was arrange the numbers into a ratio, and simplify.
These problems are meant to to be confusing, so to stay away from the confusing parts, just reread them and you'll get it correct 24/7!
Hope you get this right.

Find the value of X please answer as soon as anyone can!
Answer:
139
Step-by-step explanation:
180 = x + 64+45
therefore: x = 139
Answer:
x = 109
Steps:
the sum of triangle angles is 180, and since the x is an exterior angle then 180-(64+45) = 71 and since it is an exterior angle then 180-71 = 109.
