Peter is saving to buy a camera. The camera costs $50. Peter has already saved $23.25. His plan is to save $4.50 every week to s

Virty [35]

Answer:

m ≥ 6

Here, m is the number of weeks Peter need to save money.

Step-by-step explanation:

The cost of the camera = $50

The amount of money already saved = $23.25

The money saved in 1 week = $4.50

Now, The TOTAL money LEFT to be saved = Total camera cost - Money already saved

= $50 - $23.25 = $26.75

So, there is $26.75 yet to be saved.

Let us assume it takes m weeks to save $26.75.

So, money saved in m weeks = m x ( Money saved in 1 week)

or, $26.75. = m x ( $4.50)

or, m = $26.75 /$4.50 = 5.94

or, m = 5.94 ≈ 6 weeks

So, the money saved in at least 6 weeks = $26.75.

Hence, it would take AT LEAST 6 weeks to save up enough amount to buy the camera which costs $50.

⇒ m ≥ 6

Please help my math grade needs help

Sladkaya [172]

Answer:

4. 16.5 minutes 2508 words - Robert

5. 60 words (c)

6.I don't really know sorry :)

Step-by-step explanation:

4. 304 ÷ 2 = 1 minute 152 words - Robert

2508 ÷ 152 = 16.5 minutes 2508 words - Robert

5. 152 × 20 = 3040 words - Robert

483 ÷ 3 = 1 minute 161 words - Michaela

161 × 20 = 3220 words - Michaela

316 ÷ 2 = 1 minute 158 words - Laura

158 × 20 = 3160 words - Laura

= 3220 - 3160

= 60 words (c)

Please give me brainliest ;)

Solve the formula V = 1/3b^2 h for b.

liraira [26]

Answer:

$b=\sqrt{\frac{3V}{h}}$

Step-by-step explanation:

To solve a formula for one of its variables do that

Underline the variable

Separate it on one side and the other terms on the other side

Make its coefficient equals 1

Let us use these steps to solve our question

∵ V = $\frac{1}{3}$ b²h

→ Underline b

∴ V = $\frac{1}{3}$ <u>b²</u>h

→ Multiply both sides by 3 to cancel the denominator on the right side

∴ 3V = <u>b²</u>h

→ Divide both sides by h to move it to the other side

∴ $\frac{3V}{h}=b^{2}$

→ To find b take √ for both sides

∴ $\sqrt{\frac{3V}{h}}=\sqrt{b^{2} }$

→ The square root will cancel the power 2 of b

∴ $\sqrt{\frac{3V}{h}}=b$

→ Switch the two sides

∴ $b=\sqrt{\frac{3V}{h}}$
