The triangles below are similar. What is the value of x ?

Answer: 21/36

Step-by-step explanation:

I added both of the numbers together (15+21) and I got 36 so I just put 21 over 36. So the percentage of it is either 58% or 58.3% !

Hope it helped ;>

Answer:

0.58

Step-by-step explanation:

15 + 21 = 36

21 / 36 = 0.58

0.58

NOW SOMETIMES SOME SCHOOLWORK WILL WANT IT HAS A HIGHER DECIMAL IT DEPENDS ON UR SCHOOL SO IF 0.58 DOES END UP BEING WRONG (which is unlikely because most schools would want it this way) THEN I WOULD DO 58.33

ok have a wonderful rest of ur day :)

Answer:

6 people

Step-by-step explanation:

2 1/4 = 9/4 = 18/8

She gave 3/8 of a bag to each of the people => she gave 18/8 : 3/8 = 6 people

So, there are 6 people that live on Janet's block (maybe 7 if count Janet herself)

Answer:

6

Step-by-step explanation:

2.25 divided by 3/8 (0.375)

To double check multiply 3/8 by 6 and you'll get 2.25 (2 1/4).

Answer:

2022

9 million

Step-by-step explanation:

[tex]p(x) =-x^2 + 4x + 5[/tex]

To find the value of x when the maximum profit occurs, differentiate the function:

[tex]\implies p'(x)=-2x+4[/tex]

set it to zero and solve for x:

[tex]\implies p'(x)=0[/tex]

[tex]\implies -2x+4=0[/tex]

[tex]\implies x=2[/tex]

Therefore, the year in which the company had its largest profit was

2020 + 2 = 2022

Input found value of x into the function:

[tex]p(2) =-(2)^2 + 4(2) + 5=9[/tex]

Therefore, the amount was 9 million

Answer: C

Step-by-step explanation:

Step-by-step explanation:

the standard form for a quadratic function is

y = ax² + bx + c

our parabola had the equation

y = a(x - 2)² + q

let's do the "math" :

y = a(x² - 4x + 4) + q = ax² - 4ax + 4a + q

so, we know (when comparing with the standard form)

b = -4a

c = 4a + q

for the vertex we need to find the axis of symmetry first by using the standard formula

x = -b/2a

which is in our case

x = -(-4a)/2a = 4a/2a = 2

to get y for this x we need to find a and q first.

we are using the given points for that :

5 = a(-2)² - 4a×(-2) + 4a + q

-1 = a(4)² - 4a×4 + 4a + q

the first equation then forms into

5 = 4a + 8a + 4a + q = 16a + q

the second equation forms into

-1 = 16a - 16a + 4a + q = 4a + q

let's subtract the second from the first equation

5 = 16a + q

- -1 = 4a + q

--------------------

6 = 12a + 0

12a = 6

a = 1/2

-1 = 4a + q = 4×1/2 + q = 2 + q

q = -3

so, the original equation for our parabola is

y = 1/2 × (x - 2)² - 3

so y for the vertex (remember, x = 2) is

y = 1/2 × (2 - 2)² - 3 = 1/2 × 0 - 3 = -3

so the vertex is (2, -3)

Answer:

Tom's speed (in mph) on Monday [tex]=4mph[/tex]

Tom's speed (in mph) on Tuesday [tex]=3mph[/tex]

Step-by-step explanation:

Using Speed distance time formula.

Tom's speed (in mph) on Monday

[tex]=Distance/time.[/tex]

[tex]=1/(15/60).[/tex] [By question statements, [tex]1hr=60min].[/tex]

[tex]=4mph[/tex]

Tom's speed (in mph) on Tuesday

[tex]=Distance/time.\\ =1/(20/60).[/tex][By question statements, [tex]1hr=60min].[/tex]

[tex]=3mph.[/tex]

Hence

Tom's speed (in mph) on Monday[tex]=4mph.[/tex]

Tom's speed (in mph) on Tuesday[tex]=3mph.[/tex]

I hope this helps you

:)

On Monday, The speed of Tom will be 4 mph.

On Tuesday, The speed of Tom will be 3 mph.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

On Monday Tom takes 15 minutes to walk one mile to school.

On Tuesday he takes 20 minutes to walk the same distance.

Now,

For Monday;

Tom takes 15 minutes to walk one mile to school.

Hence, Distance = 1 mile

Time = 15 minutes = 15/60 hour

Thus, Speed = Distance / Time

                    = 1 / (15/60)

                    = 60/15

                    = 4 mph

For Tuesday;

Tom takes 20 minutes to walk one mile to school.

Hence, Distance = 1 mile

Time = 20 minutes = 20/60 hour

Thus, Speed = Distance / Time

                    = 1 / (20/60)

                    = 60/20

                    = 3 mph

Thus, On Monday, The speed of Tom will be 4 mph.

On Tuesday, The speed of Tom will be 3 mph.

Answer:

To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value. From the y-intercept point, use the slope to find a second point. The numerator of the slope tells you how many units to move up or down from the intercept, and the denominator of the slope tells you how many units to move left or right in order to plot the second point. Connect the two points and draw arrows at either end to indicate that the line extends infinitely.

Step-by-step explanation:

Since the equation is in y=mx+B form, M is the value of we can use B as the Y_Intercept and M as the slope.

Answer:

5.2812

Step-by-step explanation:

[tex]10^{x-3.6}-7=41[/tex]

Add 7 to both sides:

[tex]\implies 10^{x-3.6}=48[/tex]

Taking logs of base 10:

[tex]\implies \log_{10}10^{x-3.6}=\log_{10}48[/tex]

Apply log rule  [tex]\log a^b=b \log a[/tex]:

[tex]\implies (x-3.6)\log_{10}10=\log_{10}48[/tex]

Apply log rule [tex]\log_aa=1[/tex]:

[tex]\implies (x-3.6)\times 1 =\log_{10}48[/tex]

Simplify and solve:

[tex]\implies x-3.6=\log_{10}48[/tex]

[tex]\implies x=\log_{10}48+3.6[/tex]

[tex]\implies x = 5.281241237...[/tex]

[tex]10^{x-3.6}-7=41[/tex]

Use the rules of exponents and logarithms to solve the equation.

[tex]10^{x-3.6}-7=41[/tex]

Add 7 to both sides of the equation.

[tex]10^{x-3.6}=48[/tex]

Take the logarithm of both sides of the equation.

[tex]log(10^{x-3.6})=log(48)[/tex]

The logarithm of a number raised to a power is the power times the logarithm of the number.

[tex](x-3.6)log(10)=log(48)[/tex]

Add 3.6 to both sides of the equation.

[tex]x=log(48)-(-3.6)[/tex]

Solve by first finding [tex]log(48)[/tex] then subtract [tex](-3.6)[/tex] from the answer:

1. [tex]log(48)=1.6812412373755872181499834821531[/tex]

Now just solve the equation:

[tex]1.6812412373755872181499834821531 - (-3.6)=5.2812412373755872181499834821531[/tex]

Step-by-step explanation:

Answer:

You are correct if rounding to the nearest whole number.

I got 12.69 so if you round up, you will get 13 (see below)

Step-by-step explanation:

X*Y = 288

(X-a)*(Y-a) = 10 * 8 = 80

X-a = 10

Y-a = 8

a = Y-8 = X-10

(X-10) * X = 288

X^2 - 10X = 288

X^2-10X-288= 0

quadratic equation

[tex]X = \frac{10 +/- \sqrt{100 - (4)(-288)} }{2}[/tex]

X =              (10 + 35.38)/2 =22.69 (technically it would have 2 answers, but we only want to evaluate the positive answer)

a = X- 10 = 22.69- 10 = 12.69 which would round up to 13 if you are rounding to the nearest whole number.
