Find the surface area of this cuboid

Answer:

D. 7/4

Step-by-step explanation:

A is on the 3/4 line

Since it it would be written as 1 3/4, it needs to be improper

3/4 + 4/4 = 7/4

Answer:

7/4

Step-by-step explanation:

For the top part of the fraction, count as many lines until you get to A: 7

For the bottom part of the fraction, count how many lines between each two numbers: 4

The length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

a² + b² = c² (Pythagoras theorem)

where, c is the hypotenuse (longest length) of a triangle.

And a and b are the two other side of the triangle excluding the longest one.

Let x be the length of the missing leg of the given right triangle.

x² + 5² = 13²

x² = 13² - 5²

x² = 169 - 25

x² = 144

x = √144

x = 12

Hence,  the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Part A

The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.

Express the toy's value t, in dollars, as a function of time w in weeks after purchase.

Part B

Write an expression to represent the toy's value 10 days after purchase

Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]

Part A

Translating to the question, the toy's value as a function of time is

[tex]t=ab^{w}[/tex]

To determine constants a and b, we use points given by graph.

First, (0,5) to find a:

[tex]5=a.b^{0}[/tex]

a = 5

Now, (3,10) to determine b:

[tex]10=5b^{3}[/tex]

[tex]b=\sqrt[3]{2}[/tex]

b = 1.26

The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]

Part B

Since, the function is in weeks:

1 week = 7 days

w weeks = 10 days

[tex]w = \frac{10}{7}[/tex]

Replacing w:

[tex]t=5.(1.26)^{w}[/tex]

[tex]t=5.(1.26)^{10/7}[/tex]

Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].

Answer:

9(19)+13z=17

171+13z=17

13z=171-17

Z=154/13 is the answer

Step-by-step explanation:

Pls mark me in brain list

Answer:

z = -154/13

Step-by-step explanation:

1.) Add the numbers

9(2+17)+13=17

9(19) = 13z = 17

2.) Multiply the numbers

9 x 19 + 13z = 17

171 + 13z = 17

3.) Rearrange terms

171 + 13z = 17

13z + 171 = 17

4.) Subtract 171 from both sides of the equation

13z + 171 = 17

13z + 171 - 171 = 17 - 171

5.) Simplify

13z = -154

Solution

z = -154/13

Answer:

Step-by-step explanation:

If angles X and Y are supplementary

X+Y=90

x=16+3y

16+3y+y=90

4y=90-16

4y=74

y=74/4=18.50

x=90-18.50=71.50

Answer:

The measures of the angles are x=139° and y=41°

Step-by-step explanation:

Supplementary Angles

Supplementary angles add up to 180°. If x and y are two supplementary angles, then:

x + y = 180        [1]

Since angle x is 16 degrees more than 3 times the size of angle y:

x = 3y + 16        [2]

Substituting [2] into [1]:

3y + 16 + y = 180

Simplifying:

4y = 180 - 16 = 164

Dividing by 4:

y = 164/4 = 41

Substituting in [2]:

x = 3*41 + 16 = 139

The measures of the angles are x=139° and y=41°

Answer:

108.50 divided by 14= 7.75

Step-by-step explanation:

Distributions of probabilities help to model our world, allowing us to estimate the likelihood of a said event or to approximate the variability of incidence. It is a common way of describing the probability of an event as well as possibly forecasting it, and the further calculation can be defined as follows:

The possibility of rolling a six on a 6-sided die is [tex]\frac{1}{6}[/tex]. There are

Three 6's are therefore [tex]\binom{1}{6}^3[/tex] likely to roll.

The probability that you don't roll a 6 is [tex]\binom{5}{6}[/tex] and you are not 6 double the record is[tex]\binom{5}{6}^2[/tex].

In 5 tests, there are 10 different ways [tex]\binom{5}{3}=10[/tex] to rolle three 6s.

Then we all have together:

[tex]\to 10 \times \binom{1}{6}^3 \times \binom{5}{6}^2 \approx 0.0322[/tex]

Therefore, the final answer is "0.0322".

Radius 4.5 feet what’s is the tabletop area

The area of the table top is 63.62 square feet.

'In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object.'

According to the given problem,

Radius of the table = 4.5 feet

Since, the table is round,

Area of a circle = [tex]\pi r^{2}[/tex]

                         = π × 4.5 × 4.5

                         = 63.617

Hence, we can conclude, the area of the table-top is 63.62 square feet.

Answer:

116 deg

Step-by-step explanation:

note that an isoceles triangle always have 2 base angles that are equal.

Here we are already given one base angle of 32 deg. It follows that the other base angle must also be 32 deg.

We now have 2 angles of a triangle and we need to find the remaining one. Also recall that all 3 internal angles of a triangle sum to 180 deg. if we let the missing angle be x, then:

base angle + base angle + vertex angle = 180°

or,

32° + 32° + x° = 180°

64° + x = 180 deg

x = 180 - 64

x = 116 deg

Step-by-step explanation:

Use the formula a² + b² = c²

400 + 441 = 882

√882 = 29.7

You square the number at the end to cancel out the squared number, since both 21 and 20 aren't originally squared.

Answer:

there are 763 more apple trees than pear trees

Step-by-step explanation:

so, first we write the words into equations.

8P = A because there are 8x apples per x pear, so to make it equal we must multiply pears by 8. P+A = 981. replacing "A" in the second equation with "8P" to get P+8P=981=9P divide both sides by 9 to get 109 pear trees. knowing this we can get 981-109=A=872 apple trees. the problem asks for A-P  which we can replace the numbers to get (872)-(109)=763 more trees

There are 763 more Apple trees than Pear trees.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the number of pear trees be x.

An orchard has 8 times many apple trees as pear trees.

So, Apple trees = 8x

Now, total trees = 981

x+ 8x= 981

9x= 981

x= 981/9

x = 109

and, Apple trees = 8 (108)= 872.

So, there are 763 more Apple trees than Pear trees.
