If Anna walled for 5 miles and then turned around and went back what is her displacement?

1 answer:

3 0

If she went back 5 miles than the displacement would be 0.

Just subtract the amount of miles she went back from the miles she went forward 5 - 5 = 0

How do you find the original price after a discount. The sales price is 55.50 and the percent of discount is 75%.

Arte-miy333 [17]

Well first we know that 55.50 is 25% so I guess multiply it by 3 to get the full price equalling nearly 166 which is closest to 165, so that’d be my answer. Sorry if wrong.

Which expression represents the volume, in cubic units, of the composite figure? One-third(8)(6)(6) (8)(6)(4) One-third(8)(6)(10

vaieri [72.5K]

The expression of Volume in cubic meter $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4)

The correct option is (1)

<h3>What is Volume?</h3>

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

Volume of rectangular pyramid= $\frac{1}{3}$ * base area* height

= $\frac{1}{3}$ * 6*8*(10-4)

= $\frac{1}{3}$ * 6*8*6

Volume of cuboid= l*b*h

= 4*6*8

So, Volume = $\frac{1}{3}$ * 6*8*6 + 4*6*8

= $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4)

So, The expression of Volume in cubic meter $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4).

Whoever checks my work and tell what I did wrong and the right answer will

gulaghasi [49]

Answer:

See below

Step-by-step explanation:

I believe that you only had to do letters F, H, and J. In that case, let's go over each one!

F: For isolating $d_{1}$ , we need to get rid of the 1/2 first. Let's multiply each side by 2:

$2*m = 2*\frac{1}{2}(d_{1}+ d_{2}) \\2m = d_{1}+ d_{2}$

After this, we just subtract $d_{2}$ from each side to get $d_{1}=2m- d_{2}$ . Dark Blue is correct! Let's now plug in those numbers below:

$d_{1}=2(10)- 13 = 20-13=7$

G: Let's isolate the vw^2 on one side by subtracting y from each side:

$vw^{2} +y-y=x-y\\vw^{2}=x-y$

Let's now divide each side by v, then put each side under a square root to get our final answer:

$\frac{vw^2}{v} = \frac{x-y}{v}\\ w^2 = \frac{x-y}{v}\\\sqrt{w^2} = \sqrt{\frac{x-y}{v}} \\w=\sqrt{\frac{x-y}{v}}$

Orange is correct! Again, let's solve the problem underneath:

w= $w=\sqrt{\frac{38-(-7)}{5}} = \sqrt{\frac{38+7}{5}} = \sqrt{\frac{45}{5}}=\sqrt{9}=3$

H: This one has some stuff that we haven't worked with quite yet (like terms), but our approach is the same: isolate c on one side of the equation.

$2a-2a+3c=17a-2a+21\\3c = 15a+21\\\frac{3c}{3} = \frac{15a+21}{3}\\c = \frac{15a}{3}+ \frac{21}{3} \\c = 5a+7$

Purple is correct! Let's solve the problem:

$c = 5(\frac{16}{5})+7 = 16+7 = 23$

If 4x^2-100=0 the roots of the equation are

Marrrta [24]

Your equation:       4x² - 100   = 0

Factor the left side: (2x + 10) · (2x - 10) = 0

This equation is true if either factor is zero.

-- One factor:    2x + 10 = 0

Divide each side by 2: x + 5 = 0
Subtract 5 from each side: x = -5 .

-- The other factor:       2x - 10 = 0

Divide each side by 2: x + 5 = 0
Add 5 to each side: x =  5 .

Of the smoothie sold yesterday at Isaac's smoothie shop 1/4 we're banana and another 2/3 were strawberry What fraction of smooth

lesya [120]

Answer:

11/12

Step-by-step explanation:

Fraction of smoothie that is Banana = 1/4

Fraction of smoothie that is strawberry = 2/3

The fraction of smoothies that were either banana or strawberry

= 1/4 + 2/3

Least Common Denominator= 12

= (3 × 1 + 2 × 4)/12

= 3 + 8/12

= 11/12

The fraction of smoothies were either banana or strawberry is 11/12
