Answer:
8.5
Step-by-step explanation:
Given that;
The longest side of an acute isosceles triangle = 12 centimeters
Since the two remaining sides are congruent, then they both have the same length ;
Let the length of the two remaining sides = 2x,
The length of each side :
Length of longest side / sqrt(2)
x = 12 /sqrt(2)
x = 12 / 1.4142135
x =8.4852813
x = 8.5
there are 86 calories in 100g of bannana
there are 89 calories in 100g of yougurt
amanda has 70g of bannana and 14og yogurt
what is the total of calories in this breakfast
Answer:
72.66 calories
Step-by-step explanation:
1. find 1g of bannana = calories
86÷100g = 0.86 calories
1g of bannana = 0.86 calories
2 find 1g of yougurt = calories
89÷100g = 0.89 calories
1g of yougurt = 0.89 calories
3. 70g of bannana= 70×0.86
= 60.2 calories
4. 14g yogurt= 14×0.89
= 12.46 calories

Two angles of a triangle measures 55° and 25° what is the measure of the third angle of the triangle
Answer:
100°
Step-by-step explanation:
55°+25°+third angle=180°(by angle sum property)
80°+third angle=180°
third angle=180°-80°
third angle=100°
Answer:
The measure of the third angle of the triangle would be 100°.
Step-by-step explanation:
25 + 55 + x = 180
80 + x = 180
x = 180 - 80
x = 100

Name the theorem or postulate that can be used to prove that these triangles are similar
Answer:
SSS similarity.
Step-by-step explanation:
AA, SAS, and SSA similarities means the triangle must have an angle, which it doesn't, so by process of elimination it is SSS similarity.
By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.
In the given figure, two lines AB and CD are parallel.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Consider, the triangle AOB and the triangle COD.
Here, AB║CD
∠BAO=∠CDO (Alternate interior angles)
∠ABO=∠DCO (Alternate interior angles)
By AA similarity criteria ΔAOB≈ΔCOD
By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.

Nicolas has to repair the roof on his grandmother's house. He needs a ladder
that is 12 meters long. If one meter is approximately equal to 3.3 feet, how long
does his ladder need to be in feet?
8.7 ft
o 3.6 ft
39.6 ft
O 12.2 ft
Answer:
The ladder has 39.6 feet
Step-by-step explanation:
Length Units Conversion
To convert from meters to feet we use the relation
1 m = 3.3 ft
The ladder that Nicholas needs to repair the roof of his grandmother's hours is 12 meter long.
Converting this length to feet we have
12 * 3.3 = 39.6 ft
The ladder has 39.6 feet

Which expression(s) is (are) equivalent to
5(x + 9) + 7(y + 2) - x?
Select ALL that apply.
A. 5x + 9 + 7y + 2 - x
B. 4x + 7y + 59
OC. 5x + 45 + 7y + 14 - X
D. 11xy + 11
OE. 4x + 7y + 11
OF. 11xy + 59
Answer:
OC. 5x + 45 + 7y + 14 - X, OE. 4x + 7y + 11
Step-by-step explanation:
Because, 5(x + 9) is 5x + 45 and 7(y + 2) is 7y + 14 and so you simplify by simplifying the like terms for example 5x - x = 4x 45 + 14 = 59 and 7y stays the same.
The expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x, so option B and C are correct.
What is expression?A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations.
Given expression:
5(x + 9) + 7(y + 2) - x
If you simplify, you will get,
5x + 45 + 7y + 14 - x,
And as further simplified we get,
4x + 7y + 59
Therefore, the expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x.

What is the equation of the line in slope-intercept form?
Answer:
y = ⅗x
Step-by-step explanation:
The line passes through the point of origin, (0, 0). This implies that the graph represents a proportional relationship between x and y. Thus, in slope-intercept form, the line of a proportional graph can be represented as y = mx.
Where,
m = slope/constant of proportionality = y/x
To write an equation for the line, let's find the slope using any of the points on the line.
Using (50, 30):
Slope (m) = 30/50 = ⅗
Plug in the value of m into y = mx
Thus, equation of the line would be:
y = ⅗x

Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AE}{AC}[/tex] = [tex]\frac{DE}{BC}[/tex], substitute values
[tex]\frac{x}{4}[/tex] = [tex]\frac{12.5}{5}[/tex] ( cross- multiply )
5x = 50 ( divide both sides by 5 )
x = 10
and
[tex]\frac{AD}{AB}[/tex] = [tex]\frac{DE}{BC}[/tex] , that is
[tex]\frac{y}{3}[/tex] = [tex]\frac{12.5}{5}[/tex] ( cross- multiply )
5y = 37.5 ( divide both sides by 5 )

Answer: 187.96 cm
Step-by-step explanation: First you need to convert all of the units into centimeters. To do this you need to convert the 6 feet into inches. Since there are 12 inches in a foot, 6 feet is equal to 72 inches. Next add the 2 inches to 72, and now this means Tyson is 74 inches tall. Lastly convert the inches into centimeters by multiplying 74 by 2.54, which equals 187.96.
Answer:
187.96cm
Step-by-step explanation:
Step 1: Convert 6 feet 2 inches to centimeters.
We have 1 inch = 2.54 cm and 1 foot = 12 inches and 1 feet = 30.48 cm
=> 6 feet 2 inches is about 187.96cm

a right cone has a slant height of 17 feet and the diameter of the base it 30 feet. what is the height of the cone?
Answer:
8
Step-by-step explanation:
The height of the cone is 8 feet by using the Pythagorean theorem.
How to find the height of a cone?The height of a cone can be found using the Pythagorean theorem and the slant height and radius (or diameter) of the base.
Given that the slant height of the cone is 17 feet and the diameter of the base is 30 feet, we can use the following formula to find the height:
height = √(slant height² - (diameter/2)²)
So in this case, the height of the cone would be:
height = √(17² - (30/2)²) = √(289 - 225) = √(64) = 8
Thus, the height of the cone is 8 feet.

What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?
Subtract 13 from both sides
Divide both sides by 7
Add 5 to both sides
Multiply both sides by 4
Answer: Add 5 to both sides
What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?
Answer- Add 5 to both sides
(4/7)x - 5 = -13
• As mentioned above, first step would be,
adding 5 to both sides
=> (4/7)x - 5 + 5 = -13 + 5
=> (4/7)x = -8
• Now, transporting 7 from L.H.S. to R.H.S
=> 4x = -8 × 7
=> 4x = -56
• Now in the same way, transporting 4 from L.H.S. to R.H.S
=> x = (-56/4)
=> x = -14
• And in this way, or taking (Add 5 to both sides) as our first step, we find that the value of x is -14.
∴ x = -14
