Answer:

12cm

Step-by-step explanation:

bc= 13cm (c) hypotenuse is always c

dc= 10÷2. (b)/(a) it can be a or b, any also long it's not the hypotenuse

= 5cm

bd= use phytagoras theorem formula

c²=a²+b²

13²=5²+b²

169=25+b²

169-25=b²

144=b²

b=

[tex] \sqrt{144} [/tex]

b=12

bd=12cm

Answer:

[tex]$64, \ (x+8)^2$[/tex]

Step-by-step explanation:

A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of [tex]$ax^2+bx+c$[/tex].

The given expression is :

[tex]$x^2+16x$[/tex]

The co-efficient of the x-term in [tex]$x^2+16x$[/tex] is '16'.

So half of the term 16 ,

[tex]$\frac{16}{2} = 8$[/tex]

and [tex]$(8)^2=64$[/tex]

Now add 64 to the expression:

[tex]$x^2+16x+64$[/tex]

Therefore, the perfect square trinomial is

[tex]$(x+8)^2=x^2+16x+64$[/tex]

Answer:

15

Step-by-step explanation:

Keep, Change, Flip. That is the mantra you should have when you come to division problems with fractions. So you would keep the 5, change the sign into multiplication, and flip the fraction from 1/3 to 3/1 (which actually is just 3). Then you would multiply 5 * 3. Your answer should be 15.

Answer:

15

Step-by-step explanation:

To divide any number by a fraction, flip the fraction and then multiply:

[tex]5 \div \frac{1}{3} = 5 \cdot \frac{3}{1} = 15[/tex]

Answer:

100 cm

Step-by-step explanation:

This is a linear function with an equation of y = 20x.

Plug 5 in for x to get 100 as your answer.

Answer: 100 cm

Step-by-step explanation: Since the car can travel 20 cm per second and it traveled 80 cm in 4 sec, then it can travel 100 cm in 5 seconds

(Tip: If it asks to show your work, try drawing a ratio table and write the centimeters it travels per second .)

Answer:

answers B and E are true.

Step-by-step explanation:

(5,0) means x=5, y=0

the point of origin is (0,0) with x=0, y=0

therefore, A is wrong. yes, the point is 5 units to the right of the origin, but 0 (no) units up. and not 1.

B is therefore true.

C is therefore wrong.

D is wrong, because the point is to the right of y-axis (the vertical axis) and not on it.

E is true, because we go only to the right of the origin, but neither up or down. so, we stay on the x- axis (horizontal axis).

Answer:

[tex]\boxed {\boxed {\sf z= -0.1}}[/tex]

Step-by-step explanation:

A z-score helps describe the relationship between a value and the mean of a group of values. Basically, it tells us how many standard deviations away from the mean a value is. The formula is:

[tex]z= \frac{x- \mu}{\sigma}[/tex]

where x is the value, μ is the mean, and σ is the standard deviation.

For this standardized exam, the mean is 350 and the standard deviation is 40. We want to find the z-score for a value of 346.

Substitute the values into the formula.

[tex]z= \frac{ 346-350}{40}[/tex]

Solve the numerator.

[tex]z- \frac{ -4}{40}[/tex]

Divide.

[tex]z= -0.1[/tex]

The z score is -0.1, so the person with a score of 346 on the exam was 0.1 standard deviations lower than the mean.

Answer:

y=-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-(-3))/(3-(-4))

m=(-3+3)/(3+4)

m=0/7

m=0

y-y1=m(x-x1)

y-(-3)=0(x-(-4))

y+3=0(x+4)

y+3=0

y=0-3

y=-3

x=363.1

x=363.1

Answer:

Your answer is x=363.1

Step-by-step explanation:

To solve this we have to get X alone.

We do this by doing the inverse of everything on the same side as the X.

So for x-6.8 we add 6.8 to BOTH sides of the equation. To get x=363.1

Answer:

30.375

Step-by-step explanation:

Volume of a rectangular prism = Length times Width times Height

If width = 3, length = 2 and 1/4 and height = 4 and 1/2

Then volume = [tex]3*2\frac{1}{4} *4\frac{1}{2}[/tex]

[tex]3*2\frac{1}{4} *4\frac{1}{2} =\frac{243}{8}[/tex]

Therefore the volume of the prism is 243/8 or 30.375

Answer:

30 3/8 or 30.375 m^3

Step-by-step explanation:

I'm not sure if they want the decimal or fraction, so I gave both.

1/4 = 0.25

1/2 = 0.5

3 * 2.25 * 4.5 = 30.375 m^3

Answer:

I think the two answers would be A & D.

Explanation:

Sorry if I'm wrong.

Answer:

The answer is D

Step-by-step explanation:

To find - Enter five expressions: a sum, a difference, a product, a quotient, and one that involves at least two operations that have the value of -3/4 (the fraction)

Solution -

Expression for sum is -

1/4 + (-1) = -3/4

Expression for difference is -

(1/4 - 1) = -3/4

Expression for product is -

(-3/2)(1/2) = -3/4

Expression for quotient is -

(1 - 4)/4 = -3/4

Expression that involves at least two operations is -

-(1/4 + 2/4) = -3/4

Answer:

$ 22.5

Step-by-step explanation:

B(x) = 30.50 - 0.20x

Notice that x defines the number of prints.

For prints = x = 40

B(40) = 30.50 - 0.20(40)

B(40) = 30.50 - 8

B(40) = 22.5

Remaining amount is $22.5

B(x) is defined as at starting you had $30.50 then you kept on spending with a period of 20 cents(= 0.20 dollar). So 30.50 kept on decreasing by 0.20. Each time you spend, you give 0.20.

That's why the function is 30.50 - 0.20x.

Where x is the nunber of times you spend(buying prints)
