Fred has 5 3/4 feet of yarn he will use 1/8 foot of yarn for each decoration he makes what's the greatest number of decorations can Fred make
Answer: Tthe greatest number of decorations can Fred make = 46
Step-by-step explanation:
Total yarn = [tex]5\dfrac34[/tex] feet [tex]=\dfrac{23}{4}[/tex] feet
Yarn required for each decorartion = [tex]\dfrac18[/tex] foot
The greatest number of decorations can Fred make = (Total yarn) ÷ (Yarn required for each decorartion)
[tex]=\dfrac{\dfrac{23}{4}}{\dfrac{1}{8}}\\\\\\=\dfrac{23}{4}\times8\\\\=23\times2\\\\=46[/tex]
Hence, the greatest number of decorations can Fred make = 46

Simplify the expression. -5/8(-3/8-1/4)
Answer:
25/64
Step-by-step explanation:
To get this answer, first you need to use the distributive property:
(-3/8)(-5/8) - (1/4)(-5/8)
Next, multiply:
15/64 - (-5/32)
Change the negative signs into a positive sign:
15/64 + 5/32
Multiply 5/32 by 2 on both top and bottom:
15/64 + (5)(2)/(32)(2)
You will then get:
15/64 + 10/64
Now, add the numerators. You will get:
25/64
This is your answer. I hope it helped!

The value of x and y in the given model of triangle are 4 and 28 respectively.
What is an equilateral triangle?An equilateral triangle is a triangle in which all sides are equal and angles are also equal. The value of each angle of an equilateral triangle is 60°.
Given a tortilla chips that can be modelled as a triangle,
The sides and angles are labelled equal, so the given chips is an equilateral triangle
6x+3 = 27
6x = 24
x = 4
And, 2y+4 = 60°
2y = 56
y = 28
Hence, The value of x and y in the given model of triangle are 4 and 28 respectively.

Answer:
Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]3x -2 < 4[/tex] and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.
[tex]3x -2 < 4[/tex]
Adding 2 on both sides
[tex]3x -2+2 < 4+2\\3x < 6[/tex]
Now, we will divide 3 on both sides
[tex]\frac{3x}{3}<\frac{6}{3}\\x<2[/tex]
So, we get x < 2
Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]
Option D is correct option.

Which statements about circle O are true? Select three options. The radius of circle O is 13. The diameter of circle O is 34. LP is a diameter of circle O. ∠LMP intercepts a semicircle. The measure of arc LP is 90°.
Answer:
The radius of circle O is 13
LP is a diameter of circle O.
∠LMP intercepts a semicircle.
Step-by-step explanation:
The missing image is attached in the diagram below.
From the diagram;
we can determine the length LP by using the Pythagoras theorem.
i.e.
hypotenuse² = opposite² + adjacent²
LP² = ML² + MP²
LP² = 24² + 10²
LP² = 576 + 100
LP = [tex]\sqrt{676}[/tex]
LP = 26
Since line LP cuts the circle into two equal halves, we can say the line LP is the diameter of circle O.
if the diameter (LP) = 26
Then, the radius r = 26/2 = 13
The radius of circle O is 13.
Similarly, the arc LMP is 180° (∵ inscribed angle is 1/2 the measure of central angle), and LMP is 180°, then ∠LMP intercepts a semicircle.
Answer: A) The radius of circle O is 13.
C) LP is a diameter of circle O.
D) ∠LMP intercepts a semicircle.
