Can someone please help me to calculate this? I would really appreciate it. (-2)²(-3)³
Answer:
-108
Step-by-step explanation:
(-2)²(-3)³
When a number has an exponent, it means that the number is being multiplied to itself. For example, in (-2)², it means (-2) multiplied by itself twice since the exponent is 2. And for (-3)³, it means (-3) multiplied by itself 3 times since the exponent is 3.
= (-2)(-2)(-3)(-3)(-3)
Multiply. Remember that two negative numbers multiplied together make a positive number, and a positive and a negative number multiplied together make a negative.
= (4)(-3)(-3)(-3)
= (-12)(-3)(-3)
= (36)(-3)
= -108
Therefore, the answer is -108.
I hope this helps!

If you currently make 3200 per month and you are given a raise to 3400 per month, what is the percent change of your salary?
Answer:
6.25%
Step-by-step explanation:
% change= (chnage/original salary) × 100%
Change = new salary - original salary
Hence = 3400-3200=200
% change= (200/3200)×100%= 6.25%
Harrison ,Tad and dale ride their bikes to school Harrison rides 3/4 mile,Tad rides 3/8 and dale rides 3/6 mile. Compare and order and distances the boys ride from least the greatest
Answer:
3/8 , 3/6. 3/4
Tad drove the least miles because the miles ridden is less than both 3/6 and 3/4 miles
Dale rode the second greatest mile because the miles ridden is greater than 3/8 but less than 3/4
Harrison rode the greatest mile because the miles ridden is greater than both 3/6 and 3/8
Step-by-step explanation:
to order the miles ridden , convert the fraction to decimals. to do this, divide the numerator by the denominator
3/4 = 0.75
3/6 = 0.5 miles
3/8 = 0.374
A bottle holds exactly 2/3 pint of liquid. How many 2/3-pint bottles can be filled from a 24-pint container
Answer:
36 number of 2/3-pint bottles can be filled from a 24-pint container
Step-by-step explanation:
Volume of the container is 24 pint
Volume of the bottle is 2/3 pint
Number of 2/3 pint bottles that can be filled from 24 pint container is
[tex]\frac{24}{\frac{2}{3} } \\= 24 * \frac{3}{2} \\= 12 * 3\\= 36[/tex]
36 number of 2/3-pint bottles can be filled from a 24-pint container
El área de un terreno rectangular es de 144 metros cuadrados. Si la base es mayor 7 metros que la altura. ¿Cuáles serían las dimensiones reales? ¿Y su perímetro?
Altura = 16
Base = 9
(16 * 9 = 144)
Perímetro = 50
(16*2 + 9*2 = 50)
what is the circumference of the circle if r= 3.5 feet? Use 22/7 for pi
Answer:
circumference of circle=2πr
2×22/7×3.522hope it helps.
Help ASAP I really need an answer I don't need links please and if you don't know that answer just don't answer
Answer:
113
Step-by-step explanation:
note: to find the circumference of a circle using the radius, you use this equation -- 2[tex]\pi[/tex]r. since the radius is 18, you make the equation 2[tex]\pi[/tex]18. that gets you 36[tex]\pi[/tex], which, if put into the calculator, is about 113.
solve the quadratic equation
8x^2+16x+8=0
Answer:
8x²+16x+8=0
x²+2x+1=0
D=4-4=0

Answer:
x = -1Step-by-step explanation:
[tex]8x^2+16x+8=0[/tex] {divide both sides by 8}
[tex]x^2+2x+1=0\\\\a=1\,,\quad b=2\,,\quad c=1\\\\x=\dfrac{-2\pm\sqrt{2^2-4\cdot1\cdot1}}{2\cdot1}=\dfrac{-2\pm\sqrt{4-4}}2=\dfrac{-2\pm0}2=-1[/tex]
Jaylen and six of her younger siblings have ages that are consecutive. When they moved from San Francisco to Chicago, their ages (all seven of them) added up to 91. How old was Jaylen when they moved? Explain your thinking.

15 sibling 1
14 sibling 2
13 sibling 3
12 sibling 4
11 sibling 5
10 sibling 6
____________
91 Total
My thinking was that I started out dividing 91 by 7. That came out 13. So I knew the oldest one had to be older than 13.

Answer:
y = -|x -1| +2
Step-by-step explanation:
The transformation ...
-f(x -h) +k
reflects function f(x) over the x-axis, translates it 'h' units to the right and 'k' units up.
Your absolute value function is reflected over the x-axis, then translated 1 unit right (h=1) and 2 units up (k=2). Putting these values in the function, we have ...
y = -abs(x -1) +2
y = -|x -1| +2

Liam plays guitar in a band called Cool. The
band is paid $421.74 for every performance. If
Cool averages 3.5 shows per month, how much
money will the band earn in 3 months?
Answer: $4,428.27
Step-by-step explanation:
First you have to find out how many shows are in three months. If there is 3.5 shows in one month, multiply this by three to get the amount in 3 months.
3.5 x 3 = 10.5 shows
Now multiply the amount the band makes in one show by the number of shows.
$421.74 x 10.5 shows = $4,428.27 over the course of three months.
Hope this helps!
Which justification can be used to demonstrate the graph is correct?
The justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
[tex]\rm x+3.5 < \dfrac{1}{10}(y-2)^2[/tex]
If plug (0, 0)
0 + 3.5 < 4/10
Which is not true.
Thus, the justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.

Can someone just plz help me I'm begging plz
Answer:
x=70°
Step-by-step explanation:
Three triangles can be made out of that shape so total int. angles = 3 x 180°=540°.
so 40 + 110 + 4x + 40 + x = 540°
190+5x=540°
5x=350°
x=350/5=70°

Amy had $28 dollar’s to spend on school supplies. After buying 7 pens, she had $20.30 left. How much did each pen cost including tax?
Answer:
Step-by-step explanation:
If Amy started with 28 dollars and bought 7 pens, then had 20.30 dollars, we can subtract to find the price of all 7 pens.
28-20.30=7.70 dollars
now to find the amount for EACH pen, we divide by 7
7.70/7=1.1
each pen costed Amy 1 dollar and 10 cents with tax
Answer:
$1.10
Step-by-step explanation:
$28-$20.30=$7.70
7.70 divided by 7= 1.10
so each pen must cost $1.10
