what is the name of this shape?
Answers
Answer:
this shape consists of a square and triangle
The shape is a Pentagon ... but that won't help get the perimeter or area. you'll have to find the areas and perimeters of both the square and triangle and then add them for the final answer.
Area of figure = area of square + area of triangle
=> Area of Square = a² (a = side)
side = 3.5 cm ...so...
Area of square = a²
= 3.5 × 3.5
= 12.25 cm²
=> Area of Triangle = ½ × base × height
= ½ × 3.5 × 1.64
= 2.87cm²
Area of figure = area of square + area of triangle
Area of figure = 12.25 + 2.87
= 15.12 cm²
Perimeter of figure = P of square + P of triangle
=> P of square = 4a
= 3.5 × 4
= 14cm
=> P of isosceles triangle = 2a + base
= 2 × 2.4 + 3.5
= 4.8 + 3.5
= 8.3cm
Total perimeter of figure = P of square + P of triangle
Total perimeter = 14 + 8.3
= 22.3 cm

Answer:
y = 3x + 3
Step-by-step explanation:
Given parameters;
Coordinates of the line;
(-2, -3)
Slope of the line = 3
Unknown:
Equation of the line = ?
Solution:
The equation of any straight line is often expressed as;
y = mx + c
y and x are the coordinates
c is the intercept
Now insert values of y, x and m to find c;
-3 = 3(-2) + c
-3 = -6 + c
c = -3 + 6 = 3
The equation of the line is;
y = 3x + 3

Renate wins a $20 gift card to an online music site. After Renetta purchased 16 songs, the gift card has a remaining balance of zero dollars. Which equation represents the relationship between Y, the remaining balance on Manetta‘s gift card, and X, the number of songs purchased?
Answers
Answer:
b. 5x + 4y = 80
Step-by-step explanation:
Let us assume the remaining balance left be Y
and, the number of songs purchased be X
Given that
Wins a gift card of $20
And, the songs purchased is 16
Now if we take the fraction
= 20 ÷ 16
= 5 ÷ 4
So if we reverse this fraction
So it could be 5x and 4y
And, the amount that would come is
= $20 × 16 ÷ 4
= 80
So, the equation is 5x + 4y = 80
Hence, the correct option is b.
1. The ratio of the measures of the sides of a triangle is 5:6:8, and
its perimeter is 159.6 mm. Find the measure of the shortest side of
the triangle
Answers
Answer:
42mm
Step-by-step explanation:
Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.
5x+6x+8x = 159.6
19x = 159.6
x = 159.6 ÷ 19
x = 8.4
Shortest side of triangle (5x) = 8.4 × 5
= 42

What is an angle ?An angle is a mathematical term which we can defined, when two straight lines or rays meets at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
Given that,
All the exterior angles are,
(5x + 4), (7x + 4),(4x + 9),(4x + 1),(9x-6)
It is known that,
Sum of Interior angle & Exterior angle is equal to 180°
So we can calculate all the Interior angles,
180°- (5x + 4), 180°-(7x + 4), 180°-(4x + 9), 180°-(4x + 1), 180°-(9x-6)
Formula for sum of all the Interior angles = (2n-4)×90
So, n=5
Sum of all the Interior angles = 540°
[180°- (5x + 4)] + [180°-(7x + 4)]+[180°-(4x + 9)]+[180°-(4x + 1)] +[180°-(9x-6)] = 540
900- 29x- 12 = 540
x = 12
Hence, The value of x is, 12

Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was \$43.25$43.25dollar sign, 43, point, 25. He had to pay a \$7$7dollar sign, 7 entrance fee, and \$1.25$1.25dollar sign, 1, point, 25 for every minute he was on the trampoline.
Answers
Answer:
29 minutes
Step-by-step explanation:
Given
[tex]Total = \$43.25[/tex]
[tex]Entrance\ Fee = \$7[/tex]
[tex]Per\ Minute = \$1.25[/tex]
Required
Determine the number of minutes (t) that he was on the trampoline.
This can be expressed as:
[tex]Total\ Payment = Entrance\ Fee + Amount\ per\ minute * t[/tex]
Where t represents the number of minutes
Substitute values for Total, Entrance Fee and Amount per minute
[tex]43.25 = 7 + 1.25 * t[/tex]
[tex]43.25 = 7 + 1.25t[/tex]
Solving further to get the value of t, we have:
[tex]1.25t = 43.25 - 7[/tex]
[tex]1.25t = 36.25[/tex]
[tex]t = 36.25/1.25[/tex]
[tex]t = 29[/tex]
Answer:
29 minutes
Step-by-step explanation:
7 + 1.25t = 43.25 is the equation

steve saw 313 birds during a bird-watching trip to Yellowstone National park. he observes 15 more trumpeter swans than sandhill cranes. he saw twice as many mountain chickadees as ducky grouses. how many birds of each type did steve observe if he saw half as many trumpeter swans as ducky grouses
Answers
Answer:
trumpeter swans = 41sandhill cranes = 26mountain chickadees = 164ducky grouses = 82Step-by-step explanation:
Total number of birds = 313
trumpeter swans = ssandhill cranes = cmountain chickadees = mducky grouses = gWe have equations below based on given:
s = c + 15
m = 2g ⇒ m = 2(2s) = 4s ⇒ m = 4(c + 15)g = 2s ⇒ g = 2(c + 15)s + c + m + g = 313Substituting m, g and s as above in the last equation and finding the value of c:
c + 15 + c + 2(c + 15) + 4(c + 15) = 3137(c + 15) + c = 3137c + c + 105 = 3138c = 313 - 1058c = 208c = 208/8c = 26Then finding the other values:
s = 26 + 15 = 41g = 2s = 2*41 = 82m = 2g = 2*82 = 164A submarine dives below the surface, heading downward in six moves. If each move downward was 180 feet, where is the submarine after it is finished diving?

factorise completely 3m^2-48
Answers
Answer:
3 (m^2 - 16)
Step-by-step explanation:
factoring means taking out a common multiple of all the terms in the expression
in this case, if you multiply 3 and m^2, 3 and -16, you would get 3m^2-48
so you take the three and put it outside of the parenthesis that contains the factored terms
this leaves you with 3 (m^2 - 16)
8 - (7/10)t = 6 - (1/5)t
Answers
Answer:
t = 4
Step-by-step explanation:
Solve for t:
8 - (7 t)/10 = 6 - t/5
Hint: | Put the fractions in 8 - (7 t)/10 over a common denominator.
Put each term in 8 - (7 t)/10 over the common denominator 10: 8 - (7 t)/10 = 80/10 - (7 t)/10:
80/10 - (7 t)/10 = 6 - t/5
Hint: | Combine 80/10 - (7 t)/10 into a single fraction.
80/10 - (7 t)/10 = (80 - 7 t)/10:
1/10 (80 - 7 t) = 6 - t/5
Hint: | Put the fractions in 6 - t/5 over a common denominator.
Put each term in 6 - t/5 over the common denominator 5: 6 - t/5 = 30/5 - t/5:
(80 - 7 t)/10 = 30/5 - t/5
Hint: | Combine 30/5 - t/5 into a single fraction.
30/5 - t/5 = (30 - t)/5:
(80 - 7 t)/10 = (30 - t)/5
Hint: | Make (80 - 7 t)/10 = (30 - t)/5 simpler by multiplying both sides by a constant.
Multiply both sides by 10:
(10 (80 - 7 t))/10 = (10 (30 - t))/5
Hint: | Cancel common terms in the numerator and denominator of (10 (80 - 7 t))/10.
(10 (80 - 7 t))/10 = 10/10×(80 - 7 t) = 80 - 7 t:
80 - 7 t = (10 (30 - t))/5
Hint: | In (10 (30 - t))/5, divide 10 in the numerator by 5 in the denominator.
10/5 = (5×2)/5 = 2:
80 - 7 t = 2 (30 - t)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the right hand side:
80 - 7 t = 60 - 2 t
Hint: | Move terms with t to the left hand side.
Add 2 t to both sides:
2 t - 7 t + 80 = (2 t - 2 t) + 60
Hint: | Look for the difference of two identical terms.
2 t - 2 t = 0:
2 t - 7 t + 80 = 60
Hint: | Group like terms in 2 t - 7 t + 80.
Grouping like terms, 2 t - 7 t + 80 = 80 + (2 t - 7 t):
80 + (2 t - 7 t) = 60
Hint: | Combine like terms in 2 t - 7 t.
2 t - 7 t = -5 t:
-5 t + 80 = 60
Hint: | Isolate terms with t to the left hand side.
Subtract 80 from both sides:
(80 - 80) - 5 t = 60 - 80
Hint: | Look for the difference of two identical terms.
80 - 80 = 0:
-5 t = 60 - 80
Hint: | Evaluate 60 - 80.
60 - 80 = -20:
-5 t = -20
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -5 t = -20 by -5:
(-5 t)/(-5) = (-20)/(-5)
Hint: | Any nonzero number divided by itself is one.
(-5)/(-5) = 1:
t = (-20)/(-5)
Hint: | Reduce (-20)/(-5) to lowest terms. Start by finding the GCD of -20 and -5.
The gcd of -20 and -5 is -5, so (-20)/(-5) = (-5×4)/(-5×1) = (-5)/(-5)×4 = 4:
