Answers

Answer 1

Answer:

He is incorrect

Step-by-step explanation:

Given

[tex]Price\ off = 10\%[/tex]

Required

Is the total savings, 30%

From the question, we understand that the price of is 10%.

Since there is no other deduction to the original price of the fridge, then the 10% represents the total savings.

Hence: 30% savings is incorrect.

Practice question — Given the trapezoid to the right find the length of legs in the following isosceles trapezoid

Answers

Given:

A figure of an isosceles trapezoid with bases 18 and 24, and the vertical height is 4.

To find:

The legs of the isosceles trapezoid.

Solution:

Draw another perpendicular and name the vertices as shown in the below figure.

From the figure it is clear that the AEFD is a rectangle. So,

[tex]EF=AD=18[/tex]

Since ABCD is an isosceles trapezoid, therefore in triangle ABE and DCF,

[tex]AB=DC[/tex] (Legs of isosceles trapezoid)

[tex]AE=DF[/tex] (Vertical height of isosceles trapezoid)

[tex]m\angle AEB=m\angle DFC[/tex] (Right angle)

[tex]\Delta ABE\cong \Delta DCF[/tex] (HL postulate)

[tex]BE=CF[/tex] (CPCTC)

Now,

[tex]BE+EF+FC=BC[/tex]

[tex]2BE+18=24[/tex]

[tex]2BE=24-18[/tex]

[tex]2BE=6[/tex]

[tex]BE=3[/tex]

Using Pythagoras theorem in triangle ABE, we get

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex](AB)^2=(AE)^2+(BE)^2[/tex]

[tex](AB)^2=(4)^2+(3)^2[/tex]

[tex](AB)^2=16+9[/tex]

[tex](AB)^2=25[/tex]

Taking square root on both sides, we get

[tex]AB=\pm \sqrt{25}[/tex]

[tex]AB=\pm 5[/tex]

Side length cannot be negative. So, [tex]AB=5[/tex].

Therefore, the length of legs in the given isosceles trapezoid is 5 units.

There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 238.5 grams of this cereal

Answers

Answer: 147.87 calories

Step-by-step explanation:

Let the amount of calories in 238.5 grams of this cereal be represented by x.

Based on the information given, we can form an equation as:

110/177.4 = x/238.5

Cross multiply

177.4 × x = 238.5 × 110

x = (238.5 × 110) / 177.4

x = 147.87

Therefore, there are 147.87 calories in 238.5 grams of this cereal.

y-intercept:

[tex]-\frac{4}{3} x - 3y = 12[/tex]

[tex]-\frac{4}{3} (0) - 3y = 12[/tex]

Leticia bought a new tablet for $425. She had to pay a sales tax of 8%.

What was the amount of sales tax she paid on the tablet? Sales Tax: $

What was the total cost after sales tax that Leticia paid for the tablet? Total: $

Answers

Sale Tax: $34
Total: $459

Step to solve:
To find sale tax you would need to multiple 425, the cost of the tablet by 8% or 0.08 in decimal form to get the answer 34.

To find the total add the sale tax, 34, and the cost of the tablet, 425, to get the total, 459 dollars.
