Show that the two shorter sides in triangle A have the same length as the two shorter sides in triangle B
Answer:
Step-by-step explanation:
a). Let the unknown side of triangle A = x cm
And unknown side of triangle B = y cm
By applying Pythagoras theorem in triangle A,
13² = 12² + x²
x² = 169 - 144
x² = 25 ⇒ x = 5 cm
By applying Pythagoras theorem in triangle B,
y² = 5² + 12²
y² = 25 + 144
y = √169
y = 13 cm
Therefore, smaller sides of these triangles measure 5 cm and 12 cm and they are same in measure.
b). Since, corresponding sides of both the triangles are congruent,
By SSS property of congruence, both the triangles will be congruent.

In 2012 five US postal stamps cost $2.20 how much did 7 stamps cost
Answer:
Step-by-step explanation:First, divide 2.20 by 5 to find the price of a single stamp.
2.20 ÷ 5 = 0.44
One stamp cost $0.44
Now, you multiply this by 7 to find the cost of seven stamps.
0.44 × 7 = 3.08
In 2012, seven stamps cost $3.08
Answer:
$3.08
Step-by-step explanation:
so 5= 2,20
dividing them will get .44
now multiple by 7

The cost to mail a package is $5.00. Noah has postcard stamps that are worth $0.34 each and first-class stamps that are worth $0.49 each. a. Write an equation that relates the number of postcard stamps p, the number of first-class stamps f, and the cost of mailing the package.
Answer:
[tex]0.34p + 0.49f = 5.00[/tex]
Step-by-step explanation:
Given
[tex]Cost = \$5.00[/tex]
[tex]Postcards = \$0.34[/tex]
[tex]First-class = \$0.49[/tex]
Required
Represent as an equation
If 1 postcard costs $0.34, then p postcards cost $0.34p
If 1 first-class costs $0.49, then f first-class cost $0.49f
The addition of p postcards and f first-class equals the total cost of mailing the package.
So, we have:
[tex]0.34p + 0.49f = 5.00[/tex]
Adriana is saving to buy a camera for $150. She has $25 in her savings account. Every week she earns $9 an hour babysitting for her neighbor Mrs. Beshara. How many hours will Adrianna need to babysit in order to purchase the camera?
Answer : 14hours
Step-by-step explanation:
If a camera costs 150 dollars and she already has 25 dollars, she needs 125 dollars more
9x14=126 so she needs to works 14 hours
The number of hours needed to babysit in order to purchase the camera is 14.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amount in her account = $25
Amount earned per hour = $9
The expression to find the number of x hours to buy the camera.
25 + 9x = 150
9x = 150 - 25
9x = 125
x = 13.89
x = 14
Thus,
The number of hours needed is 14.

do the ratios 8/16 and 2/4 form a proportion
Answer:
Step-by-step explanation:
8/16=8:16
2/4=2:4
Answer:
Yes, the ratios 2/4 and 8/16 form a proportion. To check if two ratios form a proportion, you can cross-multiply and see if the products are equal. In this case, 2 x 16 = 4 x 8 = 32, so the products are equal. Therefore, the ratios form a proportion.

Answer:
≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height ), that is
A = [tex]\frac{1}{2}[/tex] × XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{x}{11}[/tex] ( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A = [tex]\frac{1}{2}[/tex] × 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )

3(5 - x) = 7x - 2
Answer:
exact form: x=17/10
Decimal form: x=1.7
mixed number form: 1 7/10
Answer:
x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)
Step-by-step explanation:
3(5-x) = 7x - 2
3 * 5 - 3* x = 7x - 2 (brackets means multiply)
15 - 3x = 7x - 2 (when over equal sign negative changed to positive)
15 + 2 = 7x + 3x
17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)
17/10 = x
