Because side x had two intersecting lines that create 90° angles, we can assume that if we cut off the rectangular part of the shape, the other lines would be the same. Now, we are left with the triangular shape. We know that the hypotenuse is 16, but because we got rid of the rectangular part of the shape that had 5 on that side, we have to subtract 18 by 5 to make sure the shape is correct. Now, that side is 13.
Now we solve: 13^2 +x^2=16^2.
169+x^2=256
-169 -169
———————-
X^2=87
Now you square root both sides by 2, getting X= 9.33

If = 58° and m = 120 in, what is the value of p to the nearest tenth of an inch?
Answers
Answer:
141.5 in
Step-by-step explanation:
sin 58 = m/p = 120/p
120 = psin58
120/sin 58 = p
p = 141.5 in.
Another way to look at this problem is to remember that the hypotenuse of a right triangle is the longest side. Since 141.5 is the only answer greater than 120, it would have to be the logical choice for the length of p

Mr. Alvarez makes a walkway of 3 cement slabs.He uses 14 cubic feet of cement to make the walkway.Each square slab has a volume of 4 cubic feet
Answers
Answer:
I suppose that you want to see how we can find the volume of each individual slab with the given information, the procedure is as follows.
The walkway has 3 cement slabs,
He uses a total amount of 14 cubic feet to make the complete walkway.
This means that the 3 cement slabs together have a total volume of 14 ft^3
To find the volume of each slab, we need to find the quotient between the total volume and the total number of slabs, then we get:
Volume of each slab = (14 ft^3)/3 = 4 ft^3
This means that each cement slab has a volume of 4 ft^3.
Answer:
6 ft^3

Car dealers sometimes use the rule of thumb that a car loses about 30% of its value each year. 1. Suppose you bought a new car in December 2010 for $15,000. 2. Develop a general formula for the value of the car t years after its purchase. HELP
Answers
Answer: [tex]A=15000(1.30)^t[/tex]
Step-by-step explanation:
Formula to find the price of an item after t years after withe a depreciation rate of r% is [tex]A=P(1-\dfrac{r}{100})^t[/tex], where P = Initial value of item.
Given: P = $15,000, r= 30%
Then, the value of car after t years will be :
[tex]A= 15000(1+\dfrac{30}{100})^t\\\\\Rightarrow\ A=15000(1+0.30)^t\\\\\Rightarrow\ A=15000(1.30)^t[/tex]
The required general formula for the value of the car t years after its purchase:
[tex]A=15000(1.30)^t[/tex]

Verdadero
Step-by-step explanation:
Verdadero, cuando cambias dos fracciones para darles un denominador comun la fraccion entera se sustituye para otra que tiene el mismo valor numerico que la original. Por ejemplo tenemos una fraccion 2/6 en la cual tenemos que cambiarle el denominador a uno comun con otra fraccion que es 18. Entonces sustituyemos la fraccion por la siguente fraccion 6/18. Esta nueva fraccion es equivalente a la original y los dos tienen el mismo valor numerico...

When Sarah was 6 months old, she was 21 in. tall and her head had a diameter of 4.5 in. Now, at 20
years old, she is 6 ft. 1 in. tall and her head has a diameter of 7.65 in. If Sarah is typical, should a
person at 20 years of age be considered "similar" to herself at 6 months of age? For all parts of the
problem write an equation and solve, showing ALL the work.
a. Find the ratio of height-to-head diameter for Sarah at 6 months old. If the ratio were the
same when she was 20 years old, what diameter would her head have?
b. Find the ratio of height-to-head diameter for Sarah at 20 years old. If the ratio were the
same when she was 6 months old, how tall weld she be at 6 months?
Draw or add images here
C
How close are the two ratios you found in Part (a) and Part (b)?
d. If Sarah were taller or shorter either at 6 months of age or 20 years of age, would this make
her more or less "similar" at those two ages? Explain.
Answers
Answer:
a. ratio of height to head at 6 months old is 21/4.5 =(4.66) (the height is 4.66 times the head)
- if the ratio is the same when she is 20 she would have a head with (6ft 1in =73inches) 73/ 4.66 = 15.67 inches in diameter
b. ratio height to head at 20 yrs old = 73/7.65 = 9.54 (the height is 9.54 times the head)
-she would be about 15.6 * 4.66 = 72.70 inches tall at 20 yrs old if we the ratio at 6 months old
c. in part a ratio is 4.66, in b it is 9.54. it's a big difference
d.if she was taller at 6 months old. her head size will be smaller when she is 20 yrs compare to what we calculate.
the she was shorter at 6 months old. the ratio will be smaller and the head may have been as big as her body

4. Gabby makes banana bread at her bakery every Monday and Wednesday. Her
banana bread calls for the ratio of ingredients shown
5 cups of sugar for every 50 tablespoons of butter
80 tablespoons of butter for every 32 bananas
Answers
Answer:
Top row: 3 cups, 30 tablespoons, 12 bananas
Second row: 7 cups, 70 tbs, 28 bananas
Step-by-step explanation:
The ratio is 5 (sugar) : 50 (butter)...
You can make the unit rate: 1 cup of sugar: 10 tbs of butter
Since the other ratio is 80 tbs : 32 bananas...
1 tbs : .4 bananas
So...
3 cups : 30 tbs
30 tbs : 12 bananas
28 bananas : 70 tbs
70 tbs : 7 cups

If the perimeter of the rectangle shown is 60 feet, we can use the equation 8x + 4 = 60 to find its dimensions. If the solution to this equation is x = 7, what are the dimensions of the rectangle?
Answers
Answer:
l= 28 feet
b = 2 feet
Step-by-step explanation:
The perimeter of a rectangle is given by;
P= 2(l + b)
Comparing this to the equation; 8x + 4 = 60, i can write;
2(4x + 2) = 60
This means that;
l = 4x
b = 2
but x =7
So;
l = 4* 7 = 28 feet
b = 2 feet
Assume that the lines are parallel.

Answer:
80 degrees
Step-by-step explanation:
The 132-deg angle is an exterior angle of the left triangle.
The 52-deg angle is a remote interior angle to the exterior angle above.
Angle VZY is also a remote interior angle to the exterior angle above.
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.
We use the theorem above to find the measure of angle VZY.
52 + m<VZY = 132
m<VZY = 80
Angles WZX and VZY are vertical angles, so they are congruent.
m<WZX = m<VZY = 80
Answer: 80 degrees
Answer:
m∠WZX = 80°
Step-by-step explanation:
Angle V is a flat angle, so it measures 180°.
Find ∠YVZ (blue angle): 180° - 132° = 48°
Triangle VYZ is 180° (all triangles are 180°).
Find ∠YZV (red angle): 180° - 52° - 48° = 80°
Since you know ∠YZV, you can find ∠WZX (green angle).
∠YZV and ∠WZX are opposite angles, so they are congruent.
Therefore, ∠WZX = 80°
