Fiona, Peter and Angad share some sweets in the ratio 4:5:1. Fiona gets 40 sweets. How many sweets are there altogether?

steposvetlana [31]

Answer:

100

Step-by-step explanation:

sum the parts of the ratio, 4 + 5 + 1 = 10 parts

Fiona gets 40 sweets which is 4 parts of the ratio

Divide Fiona's share by 4 to find the value of one part of the ratio

40 ÷ 4 = 10 ← 1 part of the ratio

The total number of sweets is 10 parts , thus

number of sweets in total = 10 × 10 = 100

$\large{ \tt{ \star \: S \: O \: L \: U \: T \: I \: O \: N : }}$

$\large{ \boxed{ \tt{♡ \: VOLUME \: = l \: \times b \: \times h}}}$

$\longrightarrow \: 4 \frac{1}{3} \times 3 \frac{1}{3} \times 4$

$\longrightarrow \: \frac{13}{3} \times \frac{10}{3} \times 4$

$\longrightarrow \: \frac{540}{9}$

$\longrightarrow \tt \: 57 \frac{7}{9} \: ft ^{3}$

Our final answer is 57 7 / 9 ft^3 .

Answer:

y - 10 = -1 (x+4)

y = - x + 6

Step-by-step explanation:

y - 10 = - 1 (x - - 4)

y - 10 = -x - 4

y = -x - 4 + 10

2. The alkalinity of a fluid (pH) can be modeled in terms of its hydrogen ion concentration (H+, measured in moles/liter) of the

nataly862011 [7]

Given the equation:

$pH=-log\mleft(H^+\mright)$

You know that a lab technician finds that a sample of fluid has this pH:

$pH=4.5$

Then, in order to find the hydrogen ion concentration of the fluid, you need to follow these steps:

1. Substitute the pH given in the exercise into the equation:

$4.5=-log(H^+)$

Multiply both sides by -1:

$-4.5=\log (H^+)$

2. Solve for:

$H^+$

Remember that, by definition:

$\log _b\mleft(c\mright)=a\Rightarrow b^a=c$

In this case, you can identify that:

$\begin{gathered} a=-4.5 \\ b=10 \\ c=H^+ \end{gathered}$

Hence, substituting values and simplifying, you get:

$\begin{gathered} b^a=c \\ 10^{-4.5}=H^+ \\ H^+=0.00003162278\text{ }\frac{moles}{liter} \end{gathered}$

Therefore, the answer is:

$H^+=0.00003162278\text{ }\frac{moles}{liter}$
