Answer:
Step-by-step explanation:
Rectangle area formula is : Width* Length = Area
So:
8cm*L = 96cm
L = 96cm/8cm
L = 12cm
Formula of Area of a rectangle : l×b
96=l×8
l= 96/8
l= 12
Answer : The length of the rectangle mentioned above is 12 cm.

Find the area of the trapezoid. Pls explain and I will mark brainliest.
Answer:
B. 191.4 m²Step-by-step explanation:
Split the trapezoid as pictured below
Find its height and the upper base, then find the area of the trapezoid.
There are 3 pieces, two of them are 45°×45° and 30°×60°×90° triangles
The ratio of sides of a 30°×60°×90° triangle is 1 : √3 : 2The legs of a 45x45 triangle are equalThe above mentioned properties give us:
h = 16/2 = 8 m b = 8√3 ≈ 13.85 ma = h = 8 mNow find the area:
A = 1/2( 13 + 8 + 13.85 + 13)*8 = 191.4 m²Correct choice is B
What is the perimeter of the larger square?
Answer:
32mm
Step-by-step explanation:
8*4=32
Answer:
32 mm
Step-by-step explanation:
To find the perimeter of a shape we add up the sides, and in the case of a suare all the sides are the same. So since we are given the side length of one side (8 mm) we jsut add that up 4 times to get the perimeter of 32 mm
Which equation represents the line shown on the coordinate plane below??
A straight line is represented by a linear function.
The equation of the line is [tex]y = -\frac 14 x[/tex]
From the coordinate plane, the line passes through the following points
[tex](x,y) =(0,0)\ (4,-1)[/tex]
The slope of the above points is calculated using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, the above equation becomes
[tex]m = \frac{-1 - 0}{4-0}[/tex]
This gives
[tex]m = \frac{-1}{4}[/tex]
Rewrite as:
[tex]m = -\frac{1}{4}[/tex]
The line equation is then calculated as:
[tex]y = m(x-x_1) + y_1[/tex]
So, we have:
[tex]y = -\frac 14 (x-0) + 0[/tex]
This gives
[tex]y = -\frac 14 (x)[/tex]
Remove bracket
[tex]y = -\frac 14 x[/tex]
Hence, the equation of the line is [tex]y = -\frac 14 x[/tex]

-3x+4y = 4
-5x-3y=26
Help me as soon as possible plz
Answer:
Step-by-step explanation:
-3x+4y=4
-5x-3y=26
----------------
-8x+y=30
y=8x+30
Plug 8x+30 back into -5x-3y=26
-5x-3(8x+30)=26
-5x-24x+90=20
-29x=-70
x=2.413
Plug 2.413 into y=8x+30
y=8(2.413)+30
y=19.304+30
y=49.304

If sin A = 3/5 and tan B = 15/8 and angles A and B are in Quadrant I, find the value of tan(A + B)
Answer:
[tex] \tan (A +B) = - 6\frac{6}{13} [/tex]
Step-by-step explanation:
[tex] \sin \: A = \frac{3}{5}...(given) \\ \\ \because\cos A = \pm \sqrt{1 - { \sin }^{2}\: A } \\ \\ \ \therefore\cos A = \pm \sqrt{1 - \bigg( \frac{3}{5} \bigg) ^{2}} \\ \\ \ \therefore\cos A = \pm \sqrt{1 - \frac{9}{25}} \\ \\ \therefore\cos A = \pm \sqrt{ \frac{25 - 9}{25} } \\ \\ \therefore\cos A = \pm \sqrt{ \frac{16}{25}} \\ \\ \therefore\cos A = \pm { \frac{4}{5}} \\ \\ \because \: \angle A \: is \: in \: quadrant \: I \\ \\ \therefore \: \cos A = { \frac{4}{5}} \\ \\ \tan \: A = \frac{ \sin \: A}{\cos \: A} \\ \\ \tan \: A = \frac{ \frac{3}{5} }{ \frac{4}{5} } \\ \\ \tan \: A = \frac{3}{4} \\ \\ \because \tan (A +B) = \frac{ \tan A + \tan B }{1 - \tan A \tan B } \\ \\ \therefore \tan (A +B) = \frac{ \frac{3}{4} + \frac{15}{8} }{1 - \frac{3}{4} \times \frac{15}{8} } \\ \\ \therefore \tan (A +B) = \frac{ \frac{6}{8} + \frac{15}{8} }{1 - \frac{45}{32}} \\ \\ \therefore \tan (A +B) = \frac{ \frac{21}{8} }{\frac{32 - 45}{32}} \\ \\ \therefore \tan (A +B) = \frac{ \frac{21}{8} }{\frac{ - 13}{32}} \\ \\ \therefore \tan (A +B) = \frac{21}{8} \times \bigg(- \frac{32}{13 } \bigg)\\ \\ \therefore \tan (A +B) = - \frac{84}{13} \\ \\ \therefore \tan (A +B) = - 6\frac{6}{13} [/tex]

You have a triangle with one 70 degree angle and one 40 degree angle. What is the measure of the other angle? A) 40 degrees B) 70 degrees C) 60 degrees D) 180 degrees
Answer:
B) 70 degrees
Step-by-step explanation:
The sum of angles in a triangle = 180 degrees
We are given 2 angles in the triangle = 70° and 40°
The measure of the third angle is
180° = 70° + 40° + 3rd Angle
3rd Angle = 180° - ( 70° + 40°)
= 180° - 110°
= 70°
The measure of the other angle is 70°
Option B is the correct option.
The product of two consecutive square numbers is 900.
Work out the two numbers.
Answer:
25&36
Step-by-step explanation:
25 is a square no and so is 36 and there product is 900. They are also consecutive.
Just assemble the square nos from the least i.e 4 and try solving as asked to see if it gives 900.
Thus u'll land on 25&36
Jhon jogged 5 Miles on Thursday 6 to 50 miles on Friday and 3.4 miles on Saturday how many miles does Jhon have to run in order to run 70 miles for the week _ per week.
Answer:
8 miles
Step-by-step explanation:
If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.
70÷50=1.4
So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:
1.4 minutes mile × 5 miles = 7 minutes
Thus it will take her 7 minutes to run 5 miles at this pace.
If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.
If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).
