Answer:
6 erasers
Step-by-step explanation:
The pencils and the notebook together cost $2.75, from there you can calculate how many erasers.
1 eraser would bring the total to $3, therefore Denise can buy $1.25 more of erasers which is 5. 3 + 1.25 is $4.25. therefore Denise can buy 6 erasers
Answer:
he can buy 6 erasers
Step-by-step explanation:
because if you add 1.75 plus one and add 0.25 ....6 times it will equal 4.25 i hope this was helpful
3.) There are 3 brothers. The first brother is twice as old as the second. The second is twice as old as the third.
If the sum of their ages is 28, how old is each brother?
Answer:
The first brother is 16, the second brother is 8 and the third brother is 4.
Step-by-step explanation:
Since the sum of all the brothers is 28, that means the cap of how old the oldest can be is 28. I just stated with numbers less then 28 that were dividable by two which means all the numbers had to be. So 16 for the first, 8 for the second and 4 for the youngest is the right answer I hop.

on the grid draw the graph of y = 3x + 2 for values of x + 2 for values of x from -2 to 2
Answer:
The required graph is shown below.
Step-by-step explanation:
Consider the provided equation [tex]y=3x+2[/tex]
We need to draw the graph of the equation.
Put x=0 in the above equation.
[tex]y=3(0)+2[/tex]
[tex]y=2[/tex]
The coordinate is (0,2).
Put y=0 in the given equation.
[tex]0=3x+2[/tex]
[tex]-2=3x[/tex]
[tex]x=\frac{-2}{3}[/tex]
The coordinate is ([tex]\frac{-2}{3}[/tex],0).
Now draw the graph by using the above coordinates.
The required graph is shown below.

Use the distributive property to evaluate the following expression: 9x (4 + 9)
Answer:
117x.
This is because since the 9 is outside the parenthesis, it applies to everything inside. 9x * 4 =36x and 9x * 9 =81x
36x+81x=117x.
Answer:
117x

I just need number 32 and 33 please show work if you can
Step-by-step explanation:
Interior angle + Exterior angle = 180°.
Size of Interior angle = 180° - 360°/n.
Question 32:
Exterior angle = 72°
Interior angle = 180° - 72° = 108°.
Therefore 180° - 360°/n = 108°, n = 5 => 5 sides.
Question 33:
Exterior angle = 36°
Interior angle = 180° - 36° = 144°.
Therefore 180° - 360°/n = 144°, n = 10 => 10 sides.
Answer: 32.) 108°. 5 sides
33.) 144°. 10 sides
Step-by-step explanation:
To find an interior angle subtract the given exterior angle from 180.
180 - 72 = 108
180 - 36 = 144
To find the number of sides of a regular polygon, divide 360 by the exterior angle.
360/72 = 5
360/36 = 10

Nina Milling assembles transistor radios. she is paid $0.54 for each radio assembled during a regular work week, $0.62 for each radio assembled on on sundays. What is Nina's total pay for a week in which she assembled the following number of radios?
Answer:
I would need to know the number of radios she made each day.
Step-by-step explanation:
lets say she assembled 2 radios a day, which means we would do 0.54 x 2 (that would be 1.08) and then times it by 6 ***not incuding sunday***
you would get $6.48
then for sunday we would do 0.62 x 2 (that would be 1.24) .
now we add 6.48 and 1.24 to get $7.72 a week.
Mike created a cone that has a diameter of 8 feet and a height of 3 feet. Find the volume of this cone.
Answer:
V= 50.27
Step-by-step explanation:
V=(3.14)4^2(3/3)
50.27
The volume of the cone created by mike with diameter of 3 feet is 50.24 feet³
Volume of cone-based problem:What information do we have?
Diameter of cone = 8 feet
Height of cone = 3 feet
Radius of cone = 8 / 2
Radius of cone = 4 feet
Volume of cone = (1/3)(π)(r²)(h)
Volume of cone = (1/3)(3.14)(4²)(3)
Volume of cone = (1/3)(3.14)(16)(3)
Volume of cone = 50.24 feet³

Explain how to tell if two terms are alike. Show one pair of like terms that each contain at least two variables. Show how to add these like terms. Then show a second pair of terms that are NOT alike, but share some of the same variables. Explain why they are not alike.
Answer:
Two mathematical terms are alike (not alike) , if they have same (different) variables & in same (different) mathematical treatment.
Step-by-step explanation:
Two mathematical terms are alike, if they have same variables & in same mathematical treatment.
Eg : 2 xy , 5 xy. These are alike, as they have product of x & y being multiplied with constants.
They can be added, subtracted by adding or subtracting their constants.
2 xy + 5 xy = (2 + 5) xy = 7 xy
5 xy - 2 xy = ( 5- 2 ) xy = 3 xy
Two mathematical terms that are not alike are : 2 xy & 5xz , as former has variables x & y, latter has variables x & zcan someone help me thanks you get 15 points!

Which set of numbers could represent the lengths of the sides of a right triangle?
O 16, 32, 36
O 8, 12, 16
O 3,4, 5
O 9, 10,
Answer:
3,4,5
Step-by-step explanation:
Here, we want to select the set that could work and the sides of a right angled triangle
the correct answer is 3,4,5
These set are called a Pythagorean triple
This is because adding the square of the two smaller number will give the square of the largest number
What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set

Answer:
1) I know that the sum will be negative because a negative number added to another negative number will still be a negative number.
2) First, I simplified -35 + (-61) to -35 - 61, which just equals -96.
-54 + 17 equals 54-17 = 37.
-96 < 37, so -35 + (-61) is less.

Answer: m∠XYQ = 122°
Step-by-step explanation:
m∠XYQ + m∠QYZ = 180°
(10a + 2) + (5a - 2) = 180
15a = 180
a = 12
m∠XYQ = 10a + 2
m∠XYQ = 10 (12) + 2 = 122
m∠XYQ = 122°

·[tex]\sqrt{8}[/tex]×[tex]\sqrt{18}[/tex]=[tex]\sqrt{144}[/tex]
[tex]\sqrt{144}[/tex]=12
Answer:
12
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex] and [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a
Given
[tex]\sqrt{8}[/tex] × [tex]\sqrt{18}[/tex]
Simplifying each radical
[tex]\sqrt{8}[/tex] = [tex]\sqrt{4(2)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{2}[/tex] = 2[tex]\sqrt{2}[/tex]
[tex]\sqrt{18}[/tex] = [tex]\sqrt{9(2)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex]
Thus
[tex]\sqrt{8}[/tex] × [tex]\sqrt{18}[/tex]
= 2[tex]\sqrt{2}[/tex] × 3[tex]\sqrt{2}[/tex]
= 2 × 3 × [tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex]

Which statements are true?
Select each correct answer.
Since −6 is 6 units to the left of 0, |−6|=6 .
The absolute value of −6 is negative.
The absolute value of −6 is less than the absolute value of 6.
−6 is closer to zero on the number line than −7 , so |−6|<|−7| .
Answer:
The first one and the last one are true (Since −6 is 6 units to the left of 0, |−6|=6 and −6 is closer to zero on the number line than −7, so |−6|<|−7|.)
Step-by-step explanation:
Absolute value is the distance to zero, and it is always positive. That means the positive and negative versions of a number have the same absolute value. That means the first one is true, and the second and third ones are false. For the last one, -6 is closer to zero, so that means it would be true (The absolute value of -6 is 6, and the absolute value of -7 is 7).
