Hope this helps. Plz give brainliest

Answer:

x = 10

Step-by-step explanation:

3.4x - 1.3x - 7 - 9 = 5

2.1x - 7 - 9 = 5

2.1x - 16 = 5

2.1x - 16 + 16 = 5 + 16

2.1x = 21

2.1x ÷ 2.1 = 21 ÷ 2.1

x = 10

Answer:

30 gallons

Step-by-step explanation:

You are replacing a water heater. Before installing the new water heater, you must drain the old water heater. You want to drain it ¾ of the way before having to remove it. If the water heater holds 40 gallons. How much water must you drain?

We are told from the question that you must drain the water 3/4 of the way

The water heater holds 40 gallons

Hence,

3/4 × 40 gallons = 30 gallons.

Hence , you must drain 30 gallons of the water in the water heater.

Answer:

[tex]g^{-1}(6)=49[/tex]

Step-by-step explanation:

Inverse function

Given the function:

[tex]\displaystyle g(x) = \frac{1}{7}x-1[/tex]

Find: [tex]g^{-1}(6)[/tex]

Find the inverse function of g.

[tex]\displaystyle y = \frac{1}{7}x-1[/tex]

Add 1:

[tex]\displaystyle y +1= \frac{1}{7}x[/tex]

Multiply by 7:

[tex]7(y +1)= x[/tex]

Swap letters:

[tex]y=7(x+1)[/tex]

Call this the inverse function:

[tex]g^{-1}(x)=7(x+1)[/tex]

Evaluate at x=6

[tex]g^{-1}(6)=7(6+1)=49[/tex]

[tex]\boxed{g^{-1}(6)=49}[/tex]

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:

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 :

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]

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.

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.
