The ratio of bananas to fruit is 13 : 21
How to determine the ratio of bananas to fruit?The given parameters are
Banana = 13
Apple = 8
The total number of fruits is
Fruit = Banana + Apple
Substitute the known values in the above equation
Fruit = 13 + 8
Evaluate the sum
Fruit = 21
The ratio of bananas to fruit is then represented as:
Ratio = Banana : Fruit
Substitute the known values in the above equation
Ratio = 13 : 21
Hence, the ratio of bananas to fruit is 13 : 21

I need to find what AE is
Answer:
18
Step-by-step explanation:
The arrows on lines AB and CD indicate that these 2 shapes are similar and these 2 lines are corresponding so :
Linear scale factor :
12 ÷ 10 = 1.2 or 6/5
Let's use the fraction form
Using the linear scale factor we can make an equation to solve for x :
2x+4 = 6/5(x+8)
Expand the brackets :
2x+4 = 6/5x + 9.6
Subtract 4 from both sides :
2x = 6/5x + 5.6
Subtract 6/5x from both sides :
4/5x = 5.6
Divide both sides by 4/5 :
x = 7
Now substitute this value into the expression for the length of AE :
AE = 2(7) + 4
AE = 14 + 4
AE = 18
Hope this helped and have a good day
Answer:
116 units
Step-by-step explanation:
AE + ED = 180 because they make a straight angle and a straight angle is 180 degrees or half of a circle 360/2.
AE = 2x + 4 and ED = x +8 added together they equal 180
2x + 4 + x + 8 = 180 Combine the like terms
3x + 12 = 180 Subtract 12 from both sides of the equation
3x = 168 Divide both sides by 3
x = 56
Now that we know that x is 56 we can plug that in for AE to find its length
2x + 4
2(56) + 4
112 + 4

3. If the geometric mean of a and 25 is 20,
find the value of a.
Answer:
Value of a is 16.
Step-by-step explanation:

By using this formula
20=[tex]\sqrt{a*25}[/tex]
20=5[tex]\sqrt{a}[/tex]
dividing both side by 5, we get

:. a=16
Stuck on this problem. Help is needed please!
Step-by-step explanation:
A.
the height, the 17cm leg and half of the baseline (16/2 = 8cm) create a right-angled triangle.
so, Pythagoras applies.
c² = a² + b²
c being the Hypotenuse (side opposite of the 90° angle).
so, we get
17² = height² + 8²
289 = height² + 64
225 = height²
height = sqrt(225) = 15cm
B.
the answer to this is the surface area of the whole box.
it has 5 sides :
bottom : 20×16 rectangle = 320 cm²
left and right : 20×17 rectangles = 340×2 = 680 cm²
front and back : 16×15/2 triangles = 120×2 = 240 cm²
in total that is
320 + 680 + 240 = 1,240 cm² of cardboard

there are 6 girls and 8 boys in Mr. Stevenson's class the ratio of girls to boys in the class can be expressed as the simplified ratio ?/4 what is the missing number ?
Answer: 3
Step-by-step explanation:
The missing number in the simplified ratio ?/4 is 3.
Here, we have to find the missing number in the simplified ratio ?/4, we need to determine the ratio of girls to boys in Mr. Stevenson's class.
Given that there are 6 girls and 8 boys in the class, the ratio of girls to boys can be expressed as:
Number of girls : Number of boys = 6 : 8
To simplify the ratio, we can divide both the number of girls and the number of boys by their greatest common divisor (GCD).
In this case, the GCD of 6 and 8 is 2.
Dividing both 6 and 8 by 2, we get:
Number of girls : Number of boys = 6/2 : 8/2 = 3 : 4
So, the simplified ratio of girls to boys is 3/4.
Therefore, the missing number in the simplified ratio ?/4 is 3.

What does work mean in math?
In summary, work is done when a force acts upon an object to cause a displacement. Three quantities must be known in order to calculate the amount of work. Those three quantities are force, displacement and the angle between the force and the displacement.According to tittle, we know worker A can assemble a shelving unit in 5 hours , which means worker A can finish 1/5 of work in 1 hour . And worker B can finish 1/3 of work in 1 hour.
If A & B work together , they will spend the same time t to assemble only one shelving .
That means, 1/5t + 1/3 t = 1 (equation)
1/5 t is worker A's workload during time t , 1/3 t is worker B workload.
So, 1/5 t + 1/3t = 1 is the answer
⇒ 5t + 3t = 15
⇒ t = 15/8 hours
If they work together, they need 15/8 hours to assemble one shelving unit.

Darren’s car has a rectangular gas tank whose dimensions are 4 meters by 3 meter by 3 meters. If Darren was only able to drive for 45 hours with a full tank, what is the rate of gas consumption of his car?
Step-by-step explanation:
that is a huge gas tank. that car is practically a tank.
the volume of the gas tank is
4×3×3 = 36 m³
I assume you use liters for liquid mass.
remember
1 meter (m) = 100 centimeter (cm)
10 cm = 1/10 m = 1 decimeter (dm)
1 liter = 10×10×10 cm³ = 1000cm³ = 1 dm³
1 m³ = 10×10×10 dm³ = 1000 dm³ = 1000 liters
so, his gas tank contained 36,000 liters.
he used the 36,000 liters in 45 hours.
his corresponding rate of gas consumption was
36,000 liters / 45 hours = 800 liters / hour
At 3:00 PM a man 138 cm tall casts a shadow 149 cm long. At the same time, a tall building nearby casts a shadow 163 m long. How tall is the building?
The building is 151 meters tall
How to determine the height of the building?From the question, we have the following parameters about the building and the man
Man's height = 138 cm
Man's shadow = 149 cm
Building's shadow = 163 m
Based on the above parameters, we have the following equivalent ratio:
Ratio = Height : Shadow
So, we have:
Man's height : Man's shadow = Building's height : Building's shadow
Substitute the known values in the above equation
138 cm : 149 cm = Building's height : 163 m
Remove the units
138 : 149 = Building's height : 163
Express as fraction
138 /149 = Building's height/163
Multiply both sides by 163
Building's height = 163 * 138 /149
Evaluate the product
Building's height = 151 m
Hence, the building is 151 meters tall
So, the complete parameters are:
Man's height = 138 cm
Man's shadow = 149 cm
Building's shadow = 163 m
Building's height = 151 m

What is meant by the right triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The sum of the other two angles is 90 degrees. The perpendicular and the triangle's base are the sides that make up the right angle. The third side is the longest of the three sides, known as the hypotenuse.A right triangle's hypotenuse is its longest side, its "opposite" side is the one that faces a certain angle, and its "adjacent" side is the one that faces the angle in question. To describe the sides of right triangles, we utilize specific terminology.A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a rectangled triangle.Equivalent to tan A:
A right triangle ABC so that m∠C = 90°
