Answer:
if her cousin is 10 clare will be 15, cousin=2 clare=7, cousin=x clare= x+5. if clare= 12 then 12-5=7
The age of cousin when Clare is 12 years old is computed as 7 years.
What is meant by mathematical operations ?Mathematical operations are defined as the operations used for calculating or computing various solutions of two or more values.
Here,
Given that, Clare is 5 years older than her cousin.
Age of Clare at different ages of her cousin is calculated.
A) 10 years old
Age of Clare = 10 + 5 = 15 years old
B) 2 years old
Age of Clare = 2 + 5 = 7 years old
C) X years old
Age of Clare = X + 5 years old
Cousin's age when Clare is 12 years old can be calculated as,
Age of cousin = 12 - 5 = 7 years old
Hence,
The age of cousin when Clare is 12 years old is computed as 7 years.

if one leg of a right triangle is 12 and the other leg is 16, what is the length of the hypotenuse in this right triangle?
Answer:
20
Step-by-step explanation:
Since I am given two values of the triangle, I will input the equation a²+b²=c².
"c" represents the hypotenuse. First I plug in the values of the legs, 12²+16²=c². Next I simplify these values to 144+256=c², which is 400=c². Finally I take the square root from both the value and the variable: √400=√c² which is equivalent to 20=c. Therefore, the hypotenuse is 20. Hopefully this helps :)

The perimeter of a triangle is 6p2-4p+9 and two of its adjacent side are p2 -2p+1 and 3p2-5p+3.Find the 3rd side
Answer:
C = 2p² + 3p - 5
Step-by-step explanation:
Let A & B denote the other two adjacent sides respectively.
Let the third side be denoted by C
Given the following data;
Perimeter of triangle = 6p² - 4p + 9
Length of one side = p² - 2p + 1
Length of one side = 3p² - 5p + 3
The perimeter of a triangle is given by the addition of all its three (3) sides.
Mathematically, the perimeter of a triangle is given by the formula;
P = A + B + C
6p² - 4p + 9 = p² - 2p + 1 + 3p² - 5p + 3 + C
6p² - 4p + 9 = 4p² - 7p + 4 + C
C = 2p² + 3p - 5

Abby's curtain company is making curtains for a local hotel. She wants each curtain to be 48 inches long. At the fabric store, fabric is sold by the foot. If Abby's curtain company wants to make 55 curtains, how many feet of fabric will she need? 1 inch = 1 12 foot
Answer:
220 ft
Step-by-step explanation:
Given that:
Length of each curtain = 48 inches
Number of curtains required for Abby's curtain company = 55
Fabric of curtains is sold by the fabric store foot by foot.
Unit for conversion:
1 inch = [tex]\frac{1}{12}[/tex] foot
To find:
The fabric (in feet) needed by Abby.
Solution:
First of all, let us convert the length of each curtain (which is given in inches) to feet.
As per given hint:
1 inch = [tex]\frac{1}{12}[/tex] foot
48 inches = [tex]\frac{1}{12}[/tex] [tex]\times[/tex] 48 ft = 4 ft
So, length of one curtain is 4 ft.
Now, number of curtains required are 55.
Therefore, total length of curtains required can be found by multiplying the number of curtains with the length of one curtain.
Total length of curtain required = 55 [tex]\times[/tex] 4 = 220 ft

6.78x - 5.2 = 4.33x + 2.15
HELPPP
Answer:
x = 3
Step-by-step explanation:
6.78x - 5.2 = 4.33x + 2.15
6.78x - 4.33x = 5.2 + 2.15
2.45x = 7.35
x = 7.35/2.45
x = 3
Thus, The value of x is 3

Derrick withdrew $17 from his account on Monday. The next day he
deposited $12 in his account. What integer represents the total change in
his account over these two days?
Answer:
The total change in his account is represented by the integer -5
Step-by-step explanation:
Operations With Integers
We need to perform addition and subtraction to complete the answer to this problem.
Derrick first withdrew $17 from his account. Since the money is coming out from the account, it's considered as negative. Thus this operation is recorded as -$17.
The next day he deposited $12, which is considered as positive. This operation is considered as $12 or +$12.
The net operation or total change in the account is: -$17 + $12.
Subtracting and simplifying: -$17 + $12 = -$5
The total change in his account is represented by the integer -5

What are congruent triangles?A closed polygon made of three line portions shaping three points is known as a Triangle.
If the sides of two triangles are the same length and the angles are the same size, they are said to be congruent. As a result, it is possible to superimpose two triangles side by side and angle by angle.
Given triangles
ΔUTS and ΔRTS
which shows
UT and RS are parallel
and TS is common side
so ∠UTS = ∠RST
by UT ║ RS (side)
∠UTS = ∠RST (angle)
TS = TS (common side)
ΔUTS ≅ ΔRTS

3/10 x ? = 21/10
Answer:
7 , or 7/1
Step-by-step explanation:
Let ? = x. Set the equation:
(3/10)x = 21/10
Isolate the variable, x. Multiply 10/3 to both sides of the equation:
x * (3/10) * (10/3) = (21/10) * (10/3)
x = 21/10 * 10/3
Simplify the equation. Divide common factors from both the numerator and denominator, and then simplify:
x = (21 * 10)/(10 * 3)
x = (21/3) = 7/1 = 7
x = 7

Answer:
Colin will have to wait for 2 hours for the pond to completely empty
Step-by-step explanation:
Volume of a Prism
The volume of a prism of base area Ab and height H is computed with the formula:
V=Ab.H
We are given a pond in the shape of a prism with a trapezoidal base (front view).
The area of a trapezoid of bases b1 and b2, and height a, is given by:
[tex]\displaystyle A_b=\frac{b_1+b_2}{2}.a[/tex]
The parallel bases of the trapezoid have measures of b1=0.6 m and b2=1.4 m, and the height is a=2 m, thus the area is:
[tex]\displaystyle A_b=\frac{0.6+1.4}{2}*2[/tex]
[tex]A_b=2\ m^2[/tex]
The height of the prism is H=1m, thus the volume of the pond is:
[tex]V=2\ m^2*1\ m[/tex]
[tex]V=2\ m^3[/tex]
It's also known the level of the pond goes down by 20 cm (0.2 m) in the first 30 minutes. Note at this moment the level is still at the rectangular prism zone of the pond, thus the volume of water is calculated as the area of the face of water by the height it went down:
[tex]V_w=1\ m*2\ m*0.2\ m = 0.4\ m^3[/tex]
The pond still has this volume of water:
[tex]V_p=2\ m^3-0.4\ m^3=1.6\ m^3[/tex]
The pond was drained [tex]0.4\ m^3[/tex] in 30 minutes, thus the rest of the water will be taken out in
[tex]\frac{1.6}{0.4}*30 =120\ min[/tex]
Thus, Colin will have to wait for 2 hours for the pond to completely empty

Gavin ran 2 3/5 miles in 7/12 of an hour. How many miles can Gavin run in one hour?
Answer:
First you find how many miles can Gavin run in 1/12 of an hour. That way you can use it to times 12 and to find 12/12 of an hour which is 1 hour.
Turn it into an improper fraction. 2×5=10 then add that 10 to the numerator 3 and it'll be 13/5 miles in 7/12 hours. Then divide it by 7.
[tex] \frac{13}{5} \div 7 = \\ \frac{13 }{5 \times 7} = \frac{13}{35} [/tex]
So 13/35 is how many miles Gavin runs in 1/12 of an hour. Now times is by 12 = 146/35
Or
