8.75n=61.25

Jose made a total of 61.25 dollars, so the equation would have to equal to 61.24. He worked a certain number of hours and made 8.75 dollars per hour, so that means you have to multiply.

Answer:

8.75n =61.25 then make the equation equal to n which will make 61.25 ÷ 8.75 = n

The total amount of the initial deposit of Natalie account when she opened the account is $225.

Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.

The formula for the simple interest can be given as,

[tex]I=\dfrac{Prt}{100}[/tex]

Here, (I) is the interest amount earned on the principal amount of (P) with the rate of (r) in the time period of (t).

Natalie opened a bank account that earns 2. 5% simple interest.

Natalie's account earned $180 over the period of 10 years. The interest amount she earned is,

[tex]I=\dfrac{Prt}{100}\\I=\dfrac{180\times2.5\times10}{100}\\I=45[/tex]

The interest amount she earned is $45 and the initial amount was $180. Thus, the total amount,

[tex]A=P+I\\A=180+45\\A=225[/tex]

Thus, the total amount of the initial deposit of Natalie account when she opened the account is $225.

Answer:

There are 64 chickens

Step-by-step explanation:

60% of the animals were not chickens so I found 60% of 160 which is 96, and then I subtracted 96 from 160 and got 64

Please mark brainlest for my overcomplicated description of math

Answer:

16 horses

32 cows

48 goats

64 chickens

Step-by-step explanation:

total animals = 160

⇒ 10% of animals = 160/10 = 16

⇒ 20% = 16 x 2 = 32

⇒ 30% = 16 x 3 = 48

16 horses

32 cows

48 goats

chickens = 160 - 16 - 32 - 48 = 64

Answer:

10

Step-by-step explanation:

According to the Pythagorean theorem

x²=6²+8²=100

x=√100

x=10

Given that the two pentagons are similar figures, the area of the pool = 675 sq. m..

If two figures are similar to each other, then, the ratio of the square of their corresponding sides equals the ratio of their areas.

We are given that the pool and the park are similar to each other. The diagram given is missing, however, here's how to find the area of the pool:

If x is a side of the pool and y is the corresponding side length of the park, therefore:

area of pool/area of park = x²/y².

Plug in the values given, cross multiply and find the area of the pool.

For example, if 3 is a side of the pool = x

6 is corresponding side of the park = y

Area of park = 2,700 sq. m

Thus:

Area of pool/2,700 = 3²/6²

Area of pool/2,700 = 9/36

Area of pool = (9 × 2,700)/36

Area of pool = 675 sq. m.

Answer:

Well technically its inf due to the arrow, there  are no points showing where to start from and where to end

the way you do it it you just count the amount of units it goes up, in this case for every square its going up 5 units, once you get that number you put that on top of your fraction, then you go over on the x axis till you hit your line (x axis is going by 10 every time). This would be your number on the bottom of the fraction.

The weight would give a newborn a z-score of −0. 75 with mean 3500 g and standard deviation 500 g is 3125 grams.

Normally distributed data is the distribution of probability which is symmetric about the mean.

The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

A newborn who weighs 2,500 g or less has a low birth weight. use the information on he right to find the z score of a 2,500 g baby.

From the given parameters, the mean of the data is,

[tex]\mu=3500[/tex]

The standard deviation of the data is,

[tex]\sigma=500[/tex]

Thus, the z score can be given as,

[tex]z=\dfrac{x-\mu}{\sigma}\\-0.75=\dfrac{x-3500}{500}\\x=3125[/tex]

Hence, the weight would give a newborn a z-score of −0.75 with mean 3500 g and standard deviation 500 g is 3125 grams.

[tex]\left(-34, \dfrac{33}{2}\right)[/tex]

Step-by-step explanation:

Create a linear equation for line AB and line CD

Find slope using slope formula [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

then use point-slope form of linear equation [tex]y-y_1=m(x-x_1)[/tex]

(where m is the slope and [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line)

Line AB

[tex]m=\dfrac{-16+1}{-8+20}=-\dfrac54[/tex]

[tex]\implies y+1=-\dfrac54(x+20)\\\\\implies y=-\dfrac54x-26[/tex]

Line CD

[tex]m=\dfrac{0+11}{-19+9}=-\dfrac{11}{10}[/tex]

[tex]\implies y+11=-\dfrac{11}{10}(x+9)\\\\\implies y=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]

To find the point of intersection, equate the equations and solve for x::

AB = CD

[tex]\implies -\dfrac54x-26=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]

[tex]\implies -\dfrac{3}{20}x=\dfrac{51}{10}[/tex]

[tex]\implies x=-34[/tex]

Substitute found value of x into one of the equations and solve for y:

[tex]y=-\dfrac54(-34)-26=\dfrac{33}{2}[/tex]

Therefore, point of intersection is  [tex]\left(-34, \dfrac{33}{2}\right)[/tex]

Step-by-step explanation:

Answer:

60% of 25 should be 15.

for question 2: its 48

Step-by-step explanation:

1) 2.4 = 5% × Y

STEP 2: 2.4 = 5/100 x Y

Multiplying both sides by 100 and dividing both sides of the equation by 5 we will arrive at:

STEP 3 Y = 2.4 × 100/5

STEP 4) Y = 2.4 × 100 ÷ 5

STEP 5) Y = 48

Finally, we have found the value of Y which is 48 and that is our answer.
