Step-by-step explanation:
What number is 25% of 5/8?
(( Can someone please give the formula, this is like reading a foreign language to me lol ))
Thank you.
A percentage is essentially a fraction, but lazily written. Think of a percent as 25/100, or 0.25.
Now multiply the two.
0.25x5/8.
We need to convert 5/8 to a decimal, which is 0.625.
0.25x0.625=0.15625.
Now convert the decimal to a fraction, which is 5/32.

Submit Answer
Answers:
For original triangle, perimeter is 60. The area is 120.
The dilated triangle, perimeter is 180. The area is 1080.
Step-by-step explanation:
24 times 3=72
10 times 3=30
26 times 3=78
72+30+78=180
Perimeter of diliated triangle
1/2btimesh=area
1/2 30 times 72=1080 square units
Perimeter of original triangle
24+10+26=60 units
1/2 10 times 24=120 square units
From the picture attached,
Measure of the base of the small right triangle = 10 units
Height of the triangle = 24 units
Measure of the Hypotenuse = 26 units
Since, Perimeter of the triangle = Sum of the measures of the sides of the triangle
Therefore, Perimeter = 10 + 24 + 26
= 60 units
Area of the triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(10)(24)[/tex]
= 120 units²
Given triangle is dilated by a scale factor of 3 to form the bigger triangle,
Scale factor = 3
Since, expression for the scale factor is given by,
Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]
Therefore, length of the base of the dilated (bigger) triangle will be,
[tex]3=\frac{\text{Measure of the base of the original}}{10}[/tex]
Measure of the base of the original = 30 units
Height of the dilated triangle will be,
[tex]3=\frac{\text{Height of the dilated triangle}}{24}[/tex]
Height = 24 × 3
= 72 cm
Hypotenuse of the dilated triangle will be,
[tex]3=\frac{\text{Hypotenuse of the dilated triangle}}{26}[/tex]
Hypotenuse = 78 cm
Now the perimeter of the dilated triangle = 30 + 72 + 78
= 180 cm
Area of the dilated triangle = [tex]\frac{1}{2}(30)(72)[/tex]
= 1080 cm²

∠A and ∠B are vertical angles. If m∠A=(5x+5)∘and m∠B=(4x+29)∘, then find the measure of ∠A.
Answer:
∠A = 175∘
Step-by-step explanation:
∠A = ∠B
5x-5= 4x+29
x = 34
∠A= 34*5+5
∠A=170+5=175
5x+5= 4x + 29

I Need help ASAP please and Thankyou!!
Answer:
Step-by-step explanation:
m∠R = 180° - 110° [Linear pair of angles are supplementary]
m∠R = 70°
m∠S = 45° [Vertically opposite angles]
By triangle sum theorem,
m∠P + m∠R + m∠S = 180°
m∠P + 70° + 45° = 180°
m∠P = 180 -115
= 65°
Therefore, m∠A = m∠P = 65° [Vertically opposite angles]
By triangle sum theorem,
m∠B + m∠S + m∠T = 180°
m∠B + 45° + 65° = 180°
[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]
m∠B = 180° - 110° = 70°
m∠C + m∠B = 180° [Linear pair of angles are supplementary]
m∠C = 180° - 70° = 110°
m∠D + m∠T = 180° [Linear pair of angles are supplementary]
m∠D + 65° = 180°
m∠D = 115°

Answer:109.01
Step-by-step explanation:
3x + 2y = -7
2x - 5y = 8
please help solve!! i need my work need to me shown so please help me! ❤️
Answer:
56/19
Step-by-step explanation:
I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...
2X + 5(1.5X) = 8
2X + 7.5X = 8
9.5X = 8
19X = 16
X = 16/19
While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...
3X = 2Y
3(16/19) = 2Y
48/19 = 2Y
24/19 = Y
With the value of X and the value of Y, we can answer the question that's asked:
2X + Y = ?
2(16/19) + 24/19 =
32/19 + 24/19 =
56/19
Final Answer: 56/19
Answer:
[tex]x = - 1[/tex]

Step-by-step explanation:

[tex]2x - 5y = 8[/tex]
Apply elimination method. Let multiply the bottom equation by -3/2.
[tex]2 \times - \frac{3}{2} x = - 3[/tex]
[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]
[tex]8 \times - \frac{3}{2} = - 12[/tex]
Substitute new equation and add it to the top equation
[tex]3x + 2y = - 7[/tex]
[tex] - 3x + 7.5y = - 12[/tex]
[tex]9.5y = - 19[/tex]
[tex]y = - 2[/tex]
Now plug -2 for y into any equation and solve for x.
[tex]3x + 2( - 2) = - 7[/tex]
[tex]3x - 4 = - 7[/tex]
[tex]3x = - 3[/tex]
[tex]x = - 1[/tex]

Supppose a rectangle will undergo a rotation about the origin of a coordinate plane and a translation of 6 units down. Which of these is a true statement
Options:
The resulting rectangle will be congruent to the original rectangle regardless of the order of the rotation and the translation.
The resulting rectangle will be congruent to the original rectangle only if the rotation occurs before the translation.
The resulting rectangle will be congruent to the original rectangle only if the translation occurs before the rotation.
The resulting rectangle will not be congruent to the original rectangle regardless of the order of the rotation and the translation.

The resulting rectangle will be congruent to the original rectangle regardless of the order of the rotation and the translation.
Step-by-step explanation:
See attachment for options
Given
Shape: Rectangle
Transformation
- Rotation
- Translation 6 units down
Required
True statement about the transformation
From the options, we understand that we are to answer the question based on whether or not the image of the transformation will equal the original.
The given transformations are rigid transformations and as such, they do not in any way change the measure of the length and/or angle of the new image, after transformation
So, irrespective of which transformation comes first, both shapes will be congruent.

The value 5.1 feet long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
A string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.
Let the value is C.
The Pythagoras' theorem,
C² = (11)² + (12)²
C² = 121 + 144
C² = 265
C = 5.1 feet.
Therefore, the value is 5.1 feet.
