Katia is baking. She uses 2 ⅛ cups of sugar for cookies and 1 ⅗ cups of sugar for a cake. How much total sugar did Katia use?

Answer:

y = 48

Step-by-step explanation:

Plug in 7 for x:

y = x² - 1

y = (7)² - 1

Simplify. Remember to follow the order of operations, PEMDAS.

PEMDAS stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

~

First, solve the power, then subtract:

y = (7)² - 1

y = (7 * 7) - 1

y = (49) - 1

y = 48

48 is your value for y.

Answer:

1. 27

2. 27

3. 15

Step-by-step explanation:

The solution of the the given three expressions are 27, 22, and 15, respectively.

PEMDAS is an acronym that refers to the sequence of operations to be employed when solving equations with multiple operations. PEMDAS is an acronym that stands for P-Parenthesis, E-Exponents, M-Multiplication, D-Division, A-Addition, and S-Subtraction.

The given mathematical expressions can be solved as shown below.

Step1: Solving Parenthesis first,

= 1 + 5 · 2 + (4)²

Step2: Exponents,

= 1 + 5 · 2 + 16

Step3: Multiplication,

= 1 + 10 + 16

Step4: Addition,

= 27

Step1: Parenthesis

= 4 + 8(2.25)

Step2: Multiplication,

= 4 + 18

Step3: Addition,

= 22

Step1: Exponents,

= 0.25 · 64 - 1

Step2: Multiplication,

= 16 - 1

Step3: Subtraction,

= 15

Hence, the solution of the the given three expressions are 27, 22, and 15, respectively.

Answer:

y = -3x + 1,  y = x + 9

Step-by-step explanation:

An equation consists of a slope and the y-intercept. To find the slope, you need to plug the values into the slope formula.

y2 - y1/ x2 - x1

= -8 - 4/ 3 - (-1)

= -12/ 4

= -3

The slope of the first line is -3.

To find the y-intercept, you need to plug in either one of the coordinates into the equation, y = -3x + b

-8 = -3(3) + b

-8 = -9 + b

1 = b

The equation, for the first one, is y = -3x + 1  

Line 2:

11 - 8/ 2 - (-1)

= 1

y = 1x + b

11 = 1(2) + b

11 = 2 + b

9 = b

y = x + 9

Answer:

Step-by-step explanation:

Volume of a cone:

V = πr²(h/3)

Given:

V = 100.48

h = 6

π = 3.14

Work:

V = πr²(h/3)

100.48 = r²(3.14)(6/3)

100.48 = r²(3.14)(2)

100.48 = r²6.28

r² = 100.48/6.28

r² = 16

Solution:

Using the given information, draw a figure as shown below.

In a right triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

In the triangle ABC,

[tex]\tan 9^\circ=\dfrac{305}{x}[/tex]

[tex]x=\dfrac{305}{\tan 9^\circ}[/tex]

Answer: Y=0x+b

Step-by-step explanation:

Y=mx+b is what we need to set it to.

Since we already know the slope, we can go ahead and find the y-intercept to complete the equation

(-7,2), here -7 is the x and 2 is the y value

y=mx+b

plug all the known information now and solve for b (y-intercept)

y is 2, m (slope) is 0, x is -7

2=0(-7)+b

2=0+b

2=b

y=0x+2 or simply y=2

Answer:

98 ft

Step-by-step explanation:

28x2 + 19x2

=98

Answer:

Is the room a rectangle size? If so:

28 + 28 = 56

19 + 19 = 38

56 + 38 = 94 ft.

Opposite sides are parallel and equal:

therefore whenever there is two given lengths make sure to multiply them two times then add them together if only its a rectangle.

if its a square make sure to multiply the given length 4 times.

Step-by-step explanation:

After 7 years, Riley would $441.5 more have in her account than Ryan.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

Given that Riley invested $5,100 in an account paying an interest rate of [tex]7\tfrac{3}{4}[/tex]% compounded quarterly. Ryan invested $5,100 in an account paying an interest rate of [tex]7\tfrac{1}{4}[/tex] % compounded daily, we need to find that after 7 years how much more money would Riley have in her account than Ryan,

[tex]A = P(1+r/n)^{nt[/tex]

Where A = amount

P = principal

r = rate

n = number of times the amount is compounded and t = time

Riley = compounded quarterly,

[tex]A = P (1 + r / 4)^{4t[/tex]

[tex]A = 5100(1+0.019375)^{4(7)}\\\\A = 5100(1.019375)^{28}\\\\\\[/tex]

[tex]A = 8728.13[/tex]

Therefore, in 7 years Riley has $8728.13.

Ryan = compounded daily,

[tex]A = P (1 + r / 365)^{365t[/tex]

[tex]A = 5100(1 + 0.00019)^{356(7)}\\\\A = 5100(1.00019)^{2555}\\\\A = 8286.64[/tex]

Therefore, in 7 years Ryan has $8286.64.

Riley will have $441.5 more.

Hence after 7 years, Riley would $441.5 more have in her account than Ryan.
