In the last year, U.S. car sales of all makes and models have dropped by 16%. Let's say that a car dealer sells 325 cars. If this number drops by 16%, how many cars will the dealer sell then? Round to the nearest whole number.
A 203 cars
B 309 cars
C 273 cars
D 256 cars
Answer:
c. 273 cars
Step-by-step explanation:
First you need to find what 16% of 325 is
325x.16=52
because the number sold dropped by 16% you will subtract 52 from 325
325-52=273
you can also calculate the answer by subtracting 100% by 16%
100%-16%=84%
now you can calculate 84% of 325
325x.84=273

Answer:
-60
Step-by-step explanation:
Given the expression
5- {2*[(-5power2) -7 ] /3}
= 5- {2*[(25) -7 ] /3}
= 5- {2*[18 ] /3}
= -5 [2*6]
= -5(12)
= -60
Hence the required answer is -60

A hair dryer wastes 376J for every 1500J of electrical energy it uses. How efficient is the hairdryer?

Step-by-step explanation:
[tex] efficiency, \: \gamma = \frac{1500 - 376}{1500} \times 100 \\ \gamma = \frac{1124}{1500} \times 100 = 74.93 \\

Find the equation of a line that passes through the point (-2,4) and has a gradient of -3.
Leave your answer in the form
y
=
m
x
+
c
Equation of a line is y = mx +c
m is the gradient, which is given as -3 so now you have:
y = -3x + c
Replace y and x with the given point and solve for c:
4 = -3(-2) + c
Simplify:
4 = 6 + c
Subtract 6 from both sides:
c = -2
The equation becomes:
y = -3x-2

Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Suppose x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.
[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]
Multiplying both sides by 100, we get
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Dividing both sides by 50, we get
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
So, the amount invested at 7% is [tex]300[/tex].
The amount invested at 8% is
[tex]2(300)=600[/tex]
The amount invested at 9% is
[tex]3(300)=900[/tex]
Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.
What side lengths should be used to model a rectangle with an area of x2 + 3x – 10 square units?
x – 5 and x + 2
x – 2 and x + 5
x and x + 3
x + 3 and x – 10
Answer:
x - 2 and x + 5
Step-by-step explanation:
Given Area Of rectangle
= x² + 3x - 10
= x² + ( 5 - 2)x - 10
=x² + 5x - 2x - 10
= x ( x + 5 ) - 2 ( x + 5 )
= ( x + 5 ) ( x - 2 )

Xuan sold 9 used books for $9.80 each. With the
money from these sales, she bought 4 new books and
had $37.80 left over. What was the average amount
Xuan paid for each new book?
A. $ 5.60
B. $ 9.45
C. $10.08
D. $12.60
E. $22.05
Answer:
I think the answer is A, $5.60
Step-by-step explanation:
9.80 x 9= 88.20
88.20 - 37.80 = 50.40
5.60 x 9 = 50.40
The average amount paid for the books is $12.60
Since Xuan sold 9 used books for $9.80 each, the total amount that's paid for the books will be:
= $9.80 × 9
= $88.20
Since she bought 4 new books and had $37.80 left over, the cost of the books will be
= $88.20 - $37.80
= $50.40
Since she bought 4 books, the average amount paid for the books will be:
= $50.40/4
= $12.60
Therefore, the correct option is D

Find the area of the shaded area using the given dimensions:
The shaded area is divided up into two triangles, each with a base of 2 cm and a height of 2 cm. Use the following equation to solve for area:
A = 1/2(bh)
A = 1/2(2 · 2)
A = 1/2(4) = 2 cm²
There are two triangles, therefore:
2 × 2 = 4 cm²
Cual es la ley que establece que la suma o producto de dos números reales no dependen del orden en que se presentan los factores en la multiplicación y los sumados en la aducción ?
Answer:
Conmutativa
Step-by-step explanation:
Propiedad conmutativa : El orden de los factores no varía el producto o la suma. Un ejemplo seria 3 x 10 da lo mismo que 10 x 3 que es 30.
Con la suma 3+ 5 es lo mismo que 5+3 que es 8.
Nada mas funciona con SUMA o MULTIPLICACION. Nunca en la resta.
