Answer:

Step-by-step explanation:

Given:

In ΔEFG and ΔYXZ, ∠F ≅ ∠X and ∠E ≅ ∠Y. If m∠E = 62° and m∠X = 80°.

To find:

The measure of ∠Z.

Solution:

In ΔEFG and ΔYXZ,

∠F ≅ ∠X

m∠F = m∠X = 80°

∠E ≅ ∠Y

m∠E = m∠Y = 62°

Now, in ΔYXZ,

[tex]m\angle X+m\angle Y+m\angle Z=180^\circ[/tex]      [Angle sum property]

[tex]80^\circ+62^\circ+m\angle Z=180^\circ[/tex]

[tex]142^\circ+m\angle Z=180^\circ[/tex]

[tex]m\angle Z=180^\circ-142^\circ[/tex]

[tex]m\angle Z=38^\circ[/tex]

Therefore, the measure of ∠Z is 38°.

Answer:

∠Z=38°.

Step-by-step explanation:

Given: ∠E ≅ ∠Y, ∠F ≅ ∠X ≅ ∠∠X and ∠X = 80°.

Refer to the image below:

Since ∠E ≅ ∠Y and ∠F ≅ ∠X, this muse mean that  ∠G ≅ ∠Z. Now if ∠X = 80°, ∠F has to equal the same since the two are congruent. If you substitute the rest based off of the given, ∠Z=38°.

the answer choice is B.

Answer:

Infinite amount of solutions

Step-by-step explanation:

This is because 3(x+5) = 3x+15

so then it would be 3x+15=3x+15

Any number in the X place would make this statement true

Answer: Infinitely Many solutions

Step-by-step explanation:

you distribute the 3 to ‘x’ and ‘15’ getting 3x + 15 on the right side. All together the equation is:

3x + 15 = 3x + 15

so no matter what number you decided to add, it’ll be the same answer, therefore making it infinitely solutions.

i dont have paper with me rn so i cant actually write the equations, but slope intercept is y=mx+b form so all you have to do is find the slopes (y2-y1/x2-x1) and plug a coordinate into point slope form. simplify and rearrange to y=mx+b form. hope this helped

x = 14

Step-by-step explanation:

Step 1:

- 1/2x = - 7          Equation

Step 2:

x = - 7 ÷ - 1/2         Divide 1/2 on both sides

Step 3:

x = - 7 × - 2        Flip the Fraction

Answer:

x = 14        Multiply

Hope This Helps :)

Answer:

Step-by-step explanation:

point - slope  formula:  y - y1 = m(x-x1)

we need to find the slope ... or what is m ?

m = rise / run  

m = y2 - y1  / x2 - x1    

where the given points are  (x1,y1)  and (x2,y2)

m= 7-5 / 6-5

m = 2 / 1

m =2

now use either point and plug the slope and the point into the point-slope formula

y-5 =2(x-5)     :)

Answer:

E1488

Step-by-step explanation:

Since its E1200,

we find the total.

Total= time times money times interest.

1200*0.08 ( thats 8%) *3.

So, we multiply 1200*0.08*3.

the answer is 288.

1200+288 is 1488.

Hope this helps plz hit the crown :D

Answer:

The length of the actual bakery is 936 inches or 78 feet

Step-by-step explanation:

From the question we are told:

Janet measured a shopping center and made a scale drawing. The scale she used was 1 inch : 6 feet.

Let both the measurement of the shopping center and scale drawing be written in feet

1 foot = 12 inches

6 foot = x

Cross Multiply

x = 6 × 12 inches

x = 72 inches

Hence, the scale drawing =

Scale drawing : shopping center

1 inch = 72 inches

A bakery in the shopping center is 13 inches in the drawing. How long is the actual bakery?

This is calculated as:

1 inch = 72 inches

13 inches = x inches

Cross Multiply

x = 13 × 72 inches

x = 936 inches

The length of the shopping center = 936 inches

We convert back to feet

= 12 inches = 1foot

936 inches = x

Cross Multiply

12x = 936 × 1

x = 936/12

x = 78 feet

Therefore the length of the actual bakery is 936 inches or 78 feet

Answer:

92

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

The sum of customers over the 5 days is

[tex]\frac{sum}{5}[/tex] = 86 ( multiply both sides by 5 )

sum = 430

Thus mean over the 6 days is

mean = [tex]\frac{430+122}{6}[/tex] = [tex]\frac{552}{6}[/tex] = 92

Answer:

4/7x310=177 1/7

8/8x310=310

1 1/6x310=361 2/3

Step-by-step explanation:

Hope THis Helps :)

Answer:

4/7*310 = 177.142857

8/8*310 = 310

1 1/6*310 = 361.666667

So the order would be 4/7, 8/8, 1 1/6

Answer:

[tex]2x^2+16x+29[/tex]

Step-by-step explanation:

Given that,

[tex]g(x)=2x^2-5[/tex]

We need to find g(x+4)+2

[tex]g(x+4)=2(x+4)^2-5\\\\=2(x^2+16+8x)-5\\\\=2x^2+32+16x-5\\\\=2x^2+16x+27[/tex]

Now,

[tex]g(x+4)+2=2x^2+16x+27+2\\\\=2x^2+16x+29[/tex]

So, the value of [tex]g(x+4)+2[/tex] is  [tex]2x^2+16x+29[/tex]

Answer:

Step-by-step explanation:

Initial value is 0.2 and increase rate is powers of 2 as it doubles with each fold.

Correct one is:

The question is incomplete, the complete question is;

A grocer has 18 kg of black tea worth $3.5 per kg. She wants to mix it with green tea worth $2.6 per kg to sell the mixture at $2.9 per kg. How much of green tea should she use?

Answer:

36

Step-by-step explanation:

Let the weight of the green tea used be x kg.

From the question:

We have:

18 kg of black tea at $ 3.5 per kg. Thus total cost of black tea is 18 x 3.5 = $ 63

Cost of green tea is $2.6 per kg. Total cost of green tea is 2.6 * x = $2.6x

Total weight of the mixture is 18 + x kg.

Total cost of the mixture is = $2.9 (18 + x)

Thus,

Total cost of black tea + total cost of green tea = Total cost of the mixture

$63 + $2.6 x = $2.9 (18 + x)

$63 + $2.6x = $52.2 + $2.9x

63 – 52.2 = 0.3 x

10.8 = 0.3 x

x = 10.8/0.3

x = 36

36 kg of green tea is needed

Answer:

1

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(9 - 4) / (4 + 1)

5 / 5

= 1

So, the slope is 1.
