Answer:

i think 9.8 but im not sure

Step-by-step explanation:

The distance between points M and N is; 9.8 meters.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

From observation, it is given that the line segment MN which joins points M and N is parallel to the line JK. which follows from the fact that M and N are midpoints of KL and JL respectively.

Hence, it states that triangles NLM and JLK are congruent and by the ratio of corresponding sides equality:

NM/19.6 = 7.4/(2×7.4)

Solving;

NM = 19.6/2

NM=  9.8 meters.

This follows that, the ratio of corresponding sides of congruent triangles are equal.

The distance between points M and N is; 9.8 meters.

Answer:

0.82

Step-by-step explanation:

Step 1: (Calculating mean)

=> [tex]\frac{5+6+7}{3}[/tex]

=> [tex]\frac{18}{3}[/tex]

=> Mean = 6

Step 2:

=> (5-6)² = (-1)² = 1

=> (6-6)² = (0)² = 0

=> (7-6)² = (1)² = 1

Step 3: (Adding all values calculated in step 2)

=> 1+ 0 + 1 = 2

Step 4: (Dividing the result in step 3 by no. of observations)

=> 2/3 = 0.67

Step 5: (Get square root to calculate the deviation.)

=> [tex]\sqrt{0.67}[/tex] = 0.82

Answer:

0.4

Step-by-step explanation:

To decrease something by 60% you multiply by 0.4

Answer:

0.4

Step-by-step explanation:

Say you have an object that costs $100.

Now 60% of $100 is $60.

Subtract $60 from $100 and you get $40.

Now $100 × [tex]x[/tex] = $40

[tex]x=0.4[/tex]

$100×0.4=$40

You need to multiply it by 0.4

Step-by-step explanation:

Explanation is provided below in the image attached

Answer:

Step-by-step explanation:

For us,

P = 728,

r = .044,

e is Euler's number (a constant), and

t is 16. Filling in:

[tex]V=728e^{(.044)(16)}[/tex] and

[tex]V=728e^{(.704)}[/tex] and

V = 728(2.02182385) so

V = $1471.89

A person places $728 in an investment account earning an annual rate of 4.4%, compounded continuously. The value of the account in t years is $1471.89.

We have given that,

P = 728,

r = 0.044,

e is Euler's number (a constant), and

t = 16.

The formula of the account in t years is,

[tex]V = Pe^{rt}[/tex]

Use the given value in the above formula,

V = 728(2.02182385)

Therefore we get,

V = $1471.89

Therefore, the value of the account in t years is $1471.89.

Answer:

the ration to the money spend on ads to website is 4:3

The amount spent on advertising to the amount spent on its website as a ratio in its simplest form is: 4: 3

Given that:

Thus, the ratio of the amount spent on the advertising and the website is computed as:

£1: £ 0.75

Since a ratio can be expressed in a fraction when solving to its simplest form, then we have:

[tex]\mathbf{\dfrac{1}{0.75}}[/tex]

Let's multiply both the numerator and the denominator by 100 to shift the decimal in two places in 0.75

Then, we have:

[tex]\mathbf{=\dfrac{1\times 100}{0.75 \times 100}}[/tex]

[tex]\mathbf{=\dfrac{ 100}{75 }}[/tex]

Divide both sides by 5;

[tex]\mathbf{=\dfrac{ 20}{15 }}[/tex]

Divide both sides by 5;

[tex]\mathbf{\dfrac{4}{3}}[/tex]

Therefore, the amount spent on advertising to the amount spent on its website in ratio is 4:3

D. A cold, dry air mass interacts with a warm, moist air mass.

Step-by-step explanation:

Tornadoes are very scary and kind of cool to look at. They have a great scientific reason behind them which we can easily understand.  First, a funnel cloud forms that reaches down to the ground (you probably have seen this in video as a cloud that is heavily densed and circling). Then , warm air rises, resulting in a decrease in air pressure and finally, a cold, dry air mass interacts with a warm, moist air mass.

Answer:

Her average speed is 45 mph

Step-by-step explanation:

Let the average speed be x mph

Time taken complete the journey = distance/ average speed

Time = 300/x

Now , at 9 mph less, she could have only traveled 240 miles in same time

At 9 mph less, the average speed is x-9

so the time would be 240/x-9

since the time is same as before;

300/x = 240/x-9

Divide both sides by 60

5/x = 4/x-9

Cross multiply

5(x-9) = 4(x)

5x - 45 = 4x

5x -4x = 45

x = 45 mph

Answer: y = 6

Step-by-step explanation:if x = -30 then -2 x = 60 so 60 - 42 = 18 divide that by 3 and you get y.

Answer:

32 pizzas

60 pizzas

1/24

Step-by-step explanation:

Se hicieron 8 docenas de pizzas.

Una docena es 12, por lo tanto, el número de pizzas hechas fue:

8 * 12 = 96 pizzas

1/3 se vendieron en el local, esto significa que el número de pizzas vendidas en el local es:

1/3 * 96 = 32 pizzas

5/8 fueron para entrega a domicilio, por lo tanto, el número de pizzas vendidas en casa es:

5/8 * 96 = 60 pizzas

El número total de pizzas vendidas es:

32 + 60 = 92 pizzas

Esto significa que no se vendieron 4 pizzas. En forma de fracción:

4/96 = 1/24

Answer:

500 mg

Step-by-step explanation:

amount of dextrose in  35 ounce Pedialyte = 2500 mg

dividing LHS and RHS by 35

amount of dextrose in  35/35 ounce Pedialyte = 2500 /35 mg = 500/7 mg

Thus,

amount of dextrose in  1 ounce Pedialyte = 500 /7 mg

since we have to find amount of dextrose in  7 ounce Pedialyte

we multiply LHS and RHS by 7

Thus,

amount of dextrose in  1 *7 ounce Pedialyte = 500 /7 * 7 mg = 500 mg

amount of dextrose in  7 ounce Pedialyte = 500 mg

Thus, As child consumed 7 ounces of Pedialyte, He consumed 500 mg of dextrose.

Answer:

(Depending on the available answers) Allie has 37 quarters and 10 dimes.

Step-by-step explanation:

37 quarters add up to $9.25 (37 x 0.25 = 9.25). 10 dimes add up to $1 (10 x 0.10 = 1). 37 quarters and 10 dimes add up to $10.25. There are other ways you can divide $10.25 into quarters and dimes (such as 21 quarters and 50 dimes) but this is just one of them. I hope this helped, good luck on your test/work!
