Answer:
1. The radius of the circle is 6cm. We know this because the radius measures from the center of a circle to the outer side. Since the radius is always half the diameter then half of 12cm is 6cm
2. The diameter is 14cm. We know this because diameter measures from one edge of a circle straight across to the other side. Also the radius is always half the diameter so 7cm*2=14cm
An isosceles triangle has an angle that measures 118°. Which other angles could be in that isosceles triangle? Choose all that apply. a 69° b 31 c 118 d 54
Answer:
b. 31.
Step-by-step explanation:
The other 2 angles in the triangle are congruent so they are:
(180 - 118) / 2
= 31 degrees.
The possible measure of two similar angles in an isosceles triangle could be b. 31 °
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know in an isosceles triangle two sides are equal and angles opposite sides to the equal side are also equal.
We also know that the sum of all the interior angles in a triangle is 180°.
Let, The similar angles be 'x'.
Therefore,
x + x + 118 = 180
2x = 62.
x = 31°.

Find the value of y. Round your answers to the nearest tenth
Answer:
y ≈ 4.3
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AB}{RS}[/tex] = [tex]\frac{ED}{VU}[/tex] , substitute values
[tex]\frac{6}{4}[/tex] = [tex]\frac{8}{y+1}[/tex] ( cross- multiply )
6(y + 1) = 32
6y + 6 = 32 ( subtract 6 from both sides )
6y = 26 ( divide both sides by 6 )
y ≈ 4.3 ( to the nearest tenth )
Answer:
4.3 Is the answer like the value of X in the nearest tenth.

.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?
Answer:
90
Step-by-step explanation:
Ratio = 6 : 1 : 5
Angles are 6x ,x , 5x
Sum of all the angles of the triangle = 180
6x +x +5x = 180
12x = 180
x = 180/12
x = 15
Largest angle = 6x = 6*15 = 90

Write down the highest common factor (HCF) of A and B.Required to answer. Single line text.
(1 Point)
Given:
The two numbers are
[tex]A=23\times 3\times 5[/tex]
[tex]B=22\times 3\times 52[/tex]
To find:
The highest common factor (HCF) of A and B
Solution:
We have,
[tex]A=23\times 3\times 5[/tex] ...(i)
[tex]B=22\times 3\times 52[/tex]
All the factors of A are prime but the factors of B are not prime. So, it can be written as
[tex]B=2\times 11\times 3\times 13\times 2\times 2[/tex] ...(ii)
From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,
[tex]HCF(A,B) = 3[/tex]
Therefore, the highest common factor (HCF) of A and B is 3.

Answer: The second one
Step-by-step explanation:
How do i find this slope?!?!?!
Answer:
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Here are the equations you can use to find the slope;
Slope. y2 - y1 / x2 - x1 = slope.
Slope Intercept form. y = mx + b.
Point slope form. y - y1 = m ( x - x1)
I need help ASAP!!!!!!
Answer:
1. YES 2. NO
Step-by-step explanation:
1. Since x=0.121212... and the question is asking for 100x, we need to multiply each side by 100. 0.121212... multiplied by 100 is 12.1212... So YES, 100x is still a repeating decimal.
2. 12.121212... minus 0.121212... would just be 12. This is because if we know that all the numbers behind the decimal point is 0.121212 and so on, 12.121212... minus 0.121212... the numbers behind the decimal would cancel out. So we are left with 12. So NO, the answer for 99x is NOT a repeating decimal.

Alex only keeps ten pence coins and some twenty pence coins in
his coin box. He has a total of 18 coins which amounts to £2.30.
Work out the number of ten pence coins and twenty pence coins
in Alex's coin box.
Answer:
In the box. we have 5 20 pence coins and 13 10 pence coins
Step-by-step explanation:
Let the number of 10 pence coins be x and the number of 20 pence coins be y
The sum of these numbers is 18
Thus;
x + y = 18•••••••(i)
Writing the value in pence only
£2.30 * 100 = 230 pence
Now we have that;
total 10 pence coin amount = 10 * x = 10x
Total 20 pence coin amount = 20 * x = 20y
10x + 20y = 230
x + 2y = 23 •••••••(ii)
from ii;
x = 23-2y
Substitute this into i
23-2y + y = 18
23-18 = 2y-y
y = 5
Recall;
x + y = 18
x + 5 = 18
x = 18-5
x = 13
Sarah and Nathan each picked a bucket of strawberries. Sarah picked 4 1/4 and Nathan picked 3 3/4. How much more did Sarah pick than Nathan?
Answer: 1/2 buckets
Step-by-step explanation:
Sarah picked 4¹/₄ buckets of grapes and Nathan picked 3³/₄ buckets.
To find out how much Sarah picked more than Nathan, simply subtract Nathan's buckets from Sarah's.
First convert the fractions to improper fractions:
4¹/₄ = 17/4
3³/₄ = 15/4
As the have the same denominator, you can directly subtract them:
= 17/4 - 15/4
= 2/4
= 1/2 buckets

(Help please) Find both the perimeter and the area of the following rectangle
2x+3
X+6
Perimeter:_____
Area:____
Given:
Length of a rectangle = (2x+3) units
Width of the rectangle = (x+6) units
To find:
The perimeter and the area of the rectangle.
Solution:
We know that, the perimeter of the rectangle is
[tex]Perimeter=2(Length+Width)[/tex]
[tex]Perimeter=2((2x+3)+(x+6))[/tex]
[tex]Perimeter=2(3x+9)[/tex]
[tex]Perimeter=6x+18[/tex]
The area of rectangle is
[tex]Area=Length\times width[/tex]
[tex]Area=(2x+3)\times (x+6)[/tex]
[tex]Area=2x^2+12x+3x+18[/tex]
[tex]Area=2x^2+15x+18[/tex]
Therefore, [tex]Perimeter=6x+18[/tex] and [tex]Area=2x^2+15x+18[/tex].
Decrease £843 by 91% rounded to 2 DP
Answer:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
91% = 91/100 = 91 ÷ 100 = 0.91.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 91% of its value.
Percentage decrease = 91% × 843
New value = 843 - Percentage decrease
Calculate the New Value
New value =
843 - Percentage decrease =
843 - (91% × 843) =
843 - 91% × 843 =
(1 - 91%) × 843 =
(100% - 91%) × 843 =
9% × 843 =
9 ÷ 100 × 843 =
9 × 843 ÷ 100 =
7,587 ÷ 100 =
75.87
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 843 =
75.87 - 843 =
- 767.13
Proof.
Calculate percentage decrease:
Percentage decrease =
91% × 843 =
91 ÷ 100 × 843 =
91 × 843 ÷ 100 =
76,713 ÷ 100 =
767.13
