The tile pattern below is made up of trapezoids and rhombuses. What is the area of each figure in the pattern?
The trapezoids have a height of 2 inches and bases that measure 2 inches and 3 inches.
The rhombuses have diagonals that measure 1 inch and 4 inches.
The area of the rhombus and trapezoid from the figure are 2 square in and 5 square in respectively
How to find the area of a trapezoid and rhombus?The given pattern consists of rhombus and trapezoids
The formula for calculating the area of rhombus is expressed as:
A = pq/2
Area of trapezoid = 0.5(a+b)h
Given the following
height = 2in
a = 2in
b = 3in
Ara of rhombus = 1(4)/2 = 2 square inches
Area of the trapezoid = 0.5(2+3) * 2
Area of the trapezoid = 5 square inches
Hence the area of the rhombus and trapezoid from the figure are 2 square in and 5 square in respectively

Rice weighing 33/4 pounds was divided equally and placed in 4 containers. How many ounces of rice were in each?
Answer:
33 ounces.
Step-by-step explanation:
There are 16 ounces in a pound, so multiply 33/4 by 16, which gives you 132 ounces. We can then divide this number by 4, 132/4, giving us 33 ounces of rice in each container.
The Science Club is researching boiling points. They learn that at high altitudes, water boils
at lower temperatures. At sea level, water boils at 212°F. With each increase of 500 feet in
elevation, the boiling point of water is lowered by about 1°F.
a. 212– 1/500 e < 195
b. 1/500 e - 195 < 212
c. 195 - 212e < 1/500
d. 212 – 195e<1/ 500
The inequality expression that accurately represents the phenomena described in the question is:
212– 1/500 e < 195 (Option A)
Inequalities can be used to represent many real-life problems. Inequalities are similar to equations.
The inequality above represents the situation in which the boiling point of the sea reduces as the altitude increases.

Answer:
1.) $408.15 | 2.) $8,039.06 | 3.) 807,837.24 | 4.) $1,163.19
Step-by-step explanation:
1.) You need to know the exponential growth and decay formula.
The formula: y=ab^x
**For no.1**
Your initial amount is 300 which is the a
You need to do 100%+8% which is 108%
-This needs to be in decimal form: 1.08
4 years is the number of times the interests shall go up
Now do the equation:
y=300(1.08)^4 --> Multiply everything but do exponents first!!
y= $408.146688
$408.15 - This is the answer for no.1 it shall be rounded
**For no.2**
Same thing as last:
y=1500(1.75)^3
y= $8,039.0625
$8,039.06
**For no.3**
y=900(1.12)^60
y= 807,837.24
This had to be approximate
**For no.4**
y=820(1.06)^6
y= 1,163.1856

[tex]\sf -11+7\sqrt{2}[/tex]
Step-by-step explanation:
Given expression:
[tex]\sf \dfrac{3-\sqrt{32}}{1+\sqrt{2} }[/tex]
Rewrite 32 as 16 · 2:
[tex]\sf \implies \dfrac{3-\sqrt{16 \cdot 2}}{1+\sqrt{2} }[/tex]
Apply radical rule [tex]\sf \sqrt{a \cdot b}=\sqrt{a}\sqrt{b}[/tex]
[tex]\sf \implies \dfrac{3-\sqrt{16}\sqrt{2}}{1+\sqrt{2} }[/tex]
As [tex]\sf \sqrt{16}=4[/tex]:
[tex]\sf \implies \dfrac{3-4\sqrt{2}}{1+\sqrt{2} }[/tex]
Multiply by the conjugate:
[tex]\sf \implies \dfrac{3-4\sqrt{2}}{1+\sqrt{2} } \times \dfrac{1-\sqrt{2} }{1-\sqrt{2} }[/tex]
[tex]\sf \implies \dfrac{(3-4\sqrt{2})(1-\sqrt{2})}{(1+\sqrt{2})(1-\sqrt{2})}[/tex]
[tex]\sf \implies \dfrac{3-3\sqrt{2}-4\sqrt{2}+4\sqrt{2}\sqrt{2}}{1-\sqrt{2}+\sqrt{2}-\sqrt{2}\sqrt{2}}[/tex]
As [tex]\sf \sqrt{2}\sqrt{2}=\sqrt{4}=2[/tex]:
[tex]\sf \implies \dfrac{3-3\sqrt{2}-4\sqrt{2}+4 \cdot 2}{1-\sqrt{2}+\sqrt{2}-2}[/tex]
[tex]\sf \implies \dfrac{3-7\sqrt{2}+8}{1-2}[/tex]

y
Answer:
$12.80
Step-by-step explanation:
The cost to get 8 bottles of juice and 4 bags of chips will be:
= 8($.105) + 4($1.10)
= $8.40 + $4.40
= $12.80
The cost for x bottles of juice and y bags of chips will be:
= (1.05 × x) + (1.10 × y)
= 1.05x + 1.10y
