Answer:
Q1) 104m²
Q2) 121 in.²
Step-by-step explanation:
Q1)
GIVEN :-
Figure given in the question comprises of a triangle & a rectangle.Length of the rectangle = 10 mWidth of the rectangle = 8 m Base of the triangle = 8 mHeight of the triangle = 6 mTO FIND :-
Area of the figureGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
For a triangle with height 'h' & base 'b' , its area = [tex]\frac{1}{2} \times b \times h[/tex].For a rectangle with length 'l' & width 'w' , its area = [tex]l \times w[/tex]SOLUTION :-
Area of the triangle = [tex]\frac{1}{2} \times 8 \times 6 = 24m^2[/tex]
Area of the rectangle = [tex]10 \times 8 = 80m^2[/tex]
Area of the figure = (Area of the triangle) + (Area of the rectangle)
= 24m²+ 80m²
= 104m²
Q2)
GIVEN :-
Figure given in the question comprises of a triangle & a trapezium.Lengths of parallel sides of trapezium are 6 in. & 7 in. Height of trapezium = 20 - 3 = 17 in.Base of the triangle = 3 in.Height of the triangle = 7 in.TO FIND :-
Area of the figureGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
For a triangle with height 'h' & base 'b' , its area = [tex]\frac{1}{2} \times b \times h[/tex].For a trapezium with parallel sides whose lengths are 'a' & 'b' and height 'h' , its area = [tex]\frac{1}{2} \times (a +b) \times h[/tex]SOLUTION :-
Area of the triangle = [tex]\frac{1}{2} \times 3 \times 7 = \frac{21}{2} = 10.5 \; in.^2[/tex]
Area of the trapezium = [tex]\frac{1}{2} \times (6 +7) \times 17 = \frac{221}{2} = 110.5\; in^2[/tex]
Area of the figure = (Area of the triangle) + (Area of the trapezium)
= 10.5 in.² + 110.5 in.²

What is the measure of angle B
Answer:
Step-by-step explanation:
angle C + Angle B= Angle A(sum of two interior oppposite angles are equal to the exterior angle formed)
61+B=143
B=143-61
B=82 degree
We know that,
→ C = 61°
[A = B + C]
→ 143° = B + 61°
→ B = 143° - 61°
→ B = 82°
[180° = A + B + C]
→ 180° = A + (82° + 61°)
→ A = 180° - 143°
→ A = 37°
What is the area of 9yd and 5yd and how’d you get it
9514 1404 393
Answer:
45 yd²
Step-by-step explanation:
The area of a rectangle is the product of its length and width. If your given measures are the length and with of a rectangle, the area is found by multiplying them.
A = LW
A = (9 yd)(5 yd) = 9·5 yd·yd = 45 yd²
The area of a 9 yd by 5 yd rectangle is 45 square yards.

At the beginning of the summer Sarah has $250 she takes a summer job and saves $150 per week. Felicia has $1650 at the beginning of the summer. she travels during the summer and saves $200 per week. at the end of which week do Sarah and Felicia have the same amount of money?
Answer: 4th week
Step-by-step explanation:
You just keep adding 150 to 250 for Sarah and subtract 200 from 1,650 for Felicia until they both have the same amount which would be 850.
At the end of 4th week Sarah and Felicia have same amount of money equals to $850.
What is amount?"Amount is defined as representation of total of two or more quantities."
According to the question,
Amount with Sarah at the beginning of the week = $250
Amount save per week by Sarah = $150
Amount with Felicia at the beginning of the week = $1650
Amount save per week by Felicia = $200
As per the given conditions,
Sarah amount for different weeks:
At the end first week = $250 + $150
= $400
At the end second week = $400 + $150
= $550
At the end third week = $550 + $150
= $700
At the end fourth week = $700 + $150
= $850
Felicia amount for different weeks:
At the end first week = $1650 - $200
= $1450
At the end second week = $1450- $200
= $1250
At the end third week = $1250 - $200
= $1050
At the end fourth week = $1050- $200
= $850
Hence, at the end of 4th week Sarah and Felicia have same amount of money equals to $850.

Theresa wants to order her mother flowers for her birthday. She wants to give the delivery person a $6.00 tip. The cost of the flowers was $75. How much should she tip the driver.
Answer:
[tex]8\%[/tex]
Step-by-step explanation:
Since question already gives the number of dollars she will tip, I'm assuming it's asking for percent tipped.
Because the total is $75 and Theresa is tipping $6, she is tipping [tex]\frac{6}{75}=0.08[/tex] of the total. To convert this to a percentage, multiply by 100: [tex]0.08\implies 0.08\cdot 100=\boxed{8\%}[/tex]

Step-by-step explanation:
∠ABC= ∠DBE (vert. opp. ∠s)
(6x -7)°= (4x +23)°
6x -7= 4x +23
Being x terms to 1 side, constant to the other:
6x -4x= 23 +7
Simplify:
2x= 30
Divide both sides by 2:
x= 15
Substituting the value of x:
m∠ABC
= 6(15) -7

Express sin HH as a fraction in simplest terms.
Answer:
8 / 17
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as acute, isosceles, obtuse, scalene, equilateral and right angled triangle.
Trigonometric identities are used in a right angled triangle to show the relationship between the sides and the angles. They are:
sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse, tanθ = opposite / adjacent
From the triangle attached:
sin(H) = opposite / hypotenuse
sin(H) = 8 / 17

Answer:
Volume of the pyramid is 448 cubic meters.
Step-by-step explanation:
Volume of the given pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height of the pyramid})[/tex]
Area of the rectangular base = Length × Width
= 12 × 16
= 192 m²
Volume of the pyramid = [tex]\frac{1}{3}(192)(7)[/tex]
= 448 m³
Therefore, the volume is 448 cubic meters.

⚠️❗️⚠️❗️⚠️❗️ 10 POINTS what's the area
Answer:
263(usually it would say cm or m)²
Step-by-step explanation:
area = l x w
l= 25
w= 19
25 x 19 = 551
thats the area without subtracting the missing area's.
missing area= 9 x 16
=144
since theres 2 areas missing, times it by two
144 x 2
=288
subtract the missing area from the total because its not there.
551 - 288
= 263

April measured her bed and made a scale drawing. The scale of the drawing was 1
centimeter = 6 inches. In the drawing, the bed is 10 centimeters long. What is the
length of the actual bed?
Answer:
60 inches
Step-by-step explanation:
Given data
We have the scale of the drawing as
1cm= 6 inches
Now if 1 cm is equivalent to 6inches
then 10cm will be x inches
Cross multiply we have
x*1= 10*6
x= 60 inches
Hence the length of the actual bed is 60inches

7.5cm2
Step-by-step explanation:
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
Answer:
D.
Step-by-step explanation:
Area of a triangle is bh/2
So your base is 5 and your height is 3.
So you do 5*3 which is 15.
And lastly you do 15/2, which is 7.5. 7*2 is 14, and 8*2 is 16
So 7.5 times 2 is 15
The line x = k intersects the graph of the parabola x = -2y^2 - 3y + 5 at exactly one point. What is k? Thank you! :)
Answer:
49/8 is the value of k
Step-by-step explanation:
We have the system
x = -2y^2 - 3y + 5
x=k
We want to find k such that the system intersects once.
If we substitute the second into the first giving us k=-2y^2-3y+5 we should see we have a quadratic equation in terms of variable y.
This equation has one solution when it's discriminant is 0.
Let's first rewrite the equation in standard form.
Subtracting k on both sides gives
0=-2y^2-3y+5-k
The discriminant can be found by evaluating
b^2-4ac.
Upon comparing 0=-2y^2-3y+5-k to 0=ax^2+bx+c, we see that
a=-2, b=-3, and c=5-k.
So we want to solve the following equation for k:
(-3)^2-4(-2)(5-k)=0
9+8(5-k)=0
Distribute:
9+40-8k=0
49-8k=0
Add 8k on both sides:
49=8k
Divide both sides by 8"
49/8=k

Can someone please help me this?
Answer:
Yes
Step-by-step explanation:
We can make one equation other to the other to solve for x-value first;
=> -4x = x - 5
=> -4x + (-x) = -5
=> -5x = -5
=> x = -5/-5
=> x = 1
Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;
=> y = x - 5
=> y = (1) - 5
=> y = -4
Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.

Determine whether the lines given by the fallowing equations intersect at (-1/4,3/4) show all work. 4x+8y=5, x-3y= -3
Answer:
(0, 1)
Step-by-step explanation:
First, we need to make y the subject of the formula from both expressions
For 4x+8y=5
8y = 5- 4x
y = (5-4x)/5
Similarly for x-3y= -3
-3y = -3 - x
3y = x+3
y = (x+3)/3
Since both lines intersects, hence;
(5-4x)/5 = (x+3)/3
Cross multiply
5(x+3) = 3(5-4x)
5x + 15 = 15 - 12x
5x + 12x = 15 - 15
17x = 0
x = 0/17
x = 0
Sustitute x = 0 into any of the equations
Given that y = x+3/3
y = 0+3/3
y = 3/3
y = 1
This shows that the lines intesects at (0, 1)

Answer:
12+12+4+6+26=50
12/50=6/25=0.24=24%
Answer:
