jaun painted 4 portraits in 20 minutes. at that rate how many would he paint in 3 hours
Answer:
36 portraits
Step-by-step explanation:
4 portraits per 20 minutes. 20 minutes x 9= 3 hours. 9x4 portraits=36 portraits.
Answer:
48 portraits
Step-by-step explanation:
He can do 4 in 20 minutes. So, first figure out how many he can do in an hour. That's another 40 minutes. 40 minutes he does 8 portraits. So, 8 portraits plus 4 portraits is 16. That's one hour of painting. 16 portraits times 3 is 48, which is the amount he would paint in three hours.

Triangles ACD and BCD are isosceles. Angle BAC has a
measure of 33 degrees and angle BDC has a measure of 35
degrees. Find the measure of angle ABD.
B
Answer:
The measure of angle ∠ABD is 125°
Step-by-step explanation:
The given parameters are;
Triangle of ΔACD = Isosceles triangle
Triangle of ΔBCD = Isosceles triangle
m∠BAC = 33°
m∠BDC = 35°
Whereby ΔBCD and ΔACD have their vertex in the same direction, we can have;
[tex]\overline {AD}[/tex] ≅ [tex]\overline {AC}[/tex] Given sides legs of triangle ACD
[tex]\overline {BD}[/tex] ≅ [tex]\overline {BC}[/tex] Given sides legs of triangle BCD
[tex]\overline {BA}[/tex] ≅ [tex]\overline {BA}[/tex] Reflexive property
∴ ΔDAB ≅ ΔCAB by SSS (Side-Side-Side) congruency rule
m∠BAC ≅ m∠BAD CPCTC (Congruent Parts of Congruent Triangles are Congruent)
∴ m∠BAC ≅ m∠BAD = 33° Definition of congruency
m∠BAC + m∠BAD = 33° + 33° = 66° = m∠DAC Angle addition postulate
m∠ADC = m∠ACD = (180 - m∠DAC)/2 = (180 - 66)/2 = 57° Base angles of an isosceles triangle
∴ m∠ADC = m∠ACD = 57°
m∠BDC = 35° = m∠BCD Base angles of isosceles triangle ΔBCD
m∠BCD + m∠DBC + m∠BCD = 180° Sum of the interior angles of a triangle theorem
m∠DBC = 180° - (m∠BCD + m∠BCD) = 180° - (35° + 35°) = 110°
m∠DBC = 110°
∴ m∠ABD ≅ m∠ABC CPCTC
m∠ABD = m∠ABC Definition of congruency
m∠DBC + m∠ABD + m∠ABC = 360° Sum of angles at a point
m∠DBC + m∠ABD + m∠ABD = 360°
m∠DBC + 2 × m∠ABD = 360°
110° + 2 × m∠ABD = 360°
2 × m∠ABD = 360° - 110° = 250°
2 × m∠ABD = 250°
m∠ABD = 250°/2 = 125°
m∠ABD = 125°.
The measure of angle ABD is equal to [tex]125^\circ[/tex] and this can be determined by using the properties of the triangle.
Given :
Triangles ACD and BCD are isosceles.Angle BAC has the measure of 33 degrees and angle BDC has a measure of 35 degrees.Given that side [tex]\rm AD \cong AC[/tex].
Given that side [tex]\rm BD \cong BC[/tex].
[tex]\rm BA \cong BA[/tex] according to the reflexive property.
So, according to the above statements triangle DAB is congruent to triangle CAB by the SSS postulate.
Now according to CPCTC Angle BAD is congruent to angle BAC.
[tex]\rm \angle BAD + \angle BAC = 33 + 33 = 66^\circ[/tex]
[tex]\rm \angle DAC = 66^\circ[/tex] (according to the angle addition postulate)
[tex]\rm \angle ADC = \angle ACD = \dfrac{180-\angle DAC }{2} = \dfrac{180-66}{2}=57^\circ[/tex]
[tex]\rm \angle BDC = \angle BCD = 35^\circ[/tex]
Now, according to the sum of the interior angle of the triangle theorem:
[tex]\rm \angle BCD+\angle DBC+\angle BDC = 180^\circ[/tex]
[tex]\rm \angle DBC = 180 - 35-35 = 110^\circ[/tex]
Therefore, the angle ABD and angle ABC are congruent according to the CPCTC.
Now, according to the definition of congruency angle ABD is equal to angle ABC.
Now, again according to the sum of angles at a point:
[tex]\rm \angle DBC + \angle ABD + \angle ABC = 360^\circ[/tex]
[tex]\rm \angle DBC + \angle ABD + \angle ABD = 360^\circ[/tex]
[tex]\rm \angle DBC + 2\times \angle ABD = 360^\circ[/tex]
[tex]\rm 110+2\times \angle ABD = 180^\circ[/tex]
[tex]\rm 2\times \angle ABD = 360-110[/tex]
[tex]\rm 2\times \angle ABD = 250^\circ[/tex]
[tex]\rm \angle ABD = 125^\circ[/tex]

Item 4 A supplier sells 214 pounds of mulch for every 113 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combined. How many pounds of each item does the supplier sell? The supplier sells pounds of mulch and pounds of gravel. Item 4 A supplier sells 214 pounds of mulch for every 113 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combined. How many pounds of each item does the supplier sell? The supplier sells pounds of mulch and pounds of gravel.
Answer:
4 pounds of each item
Step-by-step explanation:
A supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combined. How many pounds of each item does the supplier sell? (Ratios and Rates)
Mulch = 2 1/4 pounds
= 9/4 Pounds
Gravel = 1 1/3 pounds
4/3 pounds
Total items sold = 172
Let x = pounds of each item the supplier sells
Mulch : gravel
9/4 : 4/3
Change into whole number by multiplying by 12
(9/4)12 : (4/3)12
= 108/4 : 48/3
= 27 : 16
Mulch : gravel = 27 : 16
27x + 16x = 172
43x = 172
Divide both sides by 43
x = 172 / 43
= 4
x = 4 pounds
Check
27x + 16x = 172
27(4) + 16(4) = 172
108 + 64 = 172
172 = 172
Therefore, the supplier sells 4 pounds of each item

What is the area of a square whose perimeter is 28x^2 + 4x?
Answer:
Step-by-step explanation:
Divide by 4 to get 1 side
28x^2/4 + 4x/4
7x^2 + 4 = s or one side
Now square that one side
Area = s^2
Area = (7x^2 + 4)^2
Area = 49x^4 + 28x^2 + 28x^2 + 16
Area = 49x^4 + 56x^2 + 16
Serena says that if a regression line is drawn correctly in a scatterplot, there will always be the same number of points above the line as there are below the line. Which of these must be a counterexample to her claim?
Options are;
1) a scatterplot with an odd number of points in which the correct regression line passes directly through 0 of the points
2) a scatterplot with an even number of points in which the correct regression line passes directly through 0 of the points
3) a scatterplot with an odd number of points in which the correct regression line passes directly through 1 of the points
4) a scatterplot with an even number of points in which the correct regression line passes directly through 2 of the points
Answer:
Option 1: a scatterplot with an odd number of points in which the correct regression line passes directly through 0 of the points
Step-by-step explanation:
From what Serena said about regression line drawn correctly in a scatter plot, looking at the options, the correct answer is option 1. This is due to the fact that If there is an odd number, and the regression line touches none of them, then there must at least be one more point located on one side of the line when compared to the point on the other side of the line.
Answer:
a scatterplot with an odd number of points in which the correct regression line passes directly through 0 of the points

Answer:
She watched for 6/8 minutes.
Simplified version would be 3/4 minutes.
Hope this helped! :)
Answer:
[tex]\frac{3}{4}[/tex] minutes
Step-by-step explanation:
To find how long she watched, add 1/8 to 5/8
Since they have the same denominators, we can add the numerators together and keep the same denominator.
[tex]\frac{1}{8}[/tex] + [tex]\frac{5}{8}[/tex]
= [tex]\frac{6}{8}[/tex]
This can be reduced to [tex]\frac{3}{4}[/tex], since both numbers are divisible by 2.
So, she watched videos for [tex]\frac{3}{4}[/tex] minutes
