Determine the smallest integer value of x in the solution of the following inequality.
4x – 1 > 18
Answer:
x = 5
Step-by-step explanation:
You need to find de value of x.
4x - 1 = 18
4x = 18 + 1
4x = 19
x = 19/4
x = 4,75 but, the questions says: smallest integer value, so, the smallest is the integer number more near of 4,75, which is 5.
testing:
x = 5
4*5 - 1 > 18
20 -1 > 18
19 > 18 TRUE
x = 4
4*4 - 1 > 18
16 - 1 > 18
15 > 18 FALSE
wanda spent 4 1/8 hours studying last night. She spent 1/3 of the time studying math. How much time did she spend studying math?
ANSWER PLSS
Answer:
[tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes
Step-by-step explanation:
Wanda spends a third of her [tex]4\frac{1}{8}[/tex] hours studying math. Let us multiply these two fractions to find how much time she spent. Our first step would be to convert the mixed number into an improper fraction, as mixed numbers are hard to manipulate with:
[tex]4\frac{1}{8} =\\\frac{33}{8}[/tex]
Now let us multiply:
[tex]\frac{1}{3} *\frac{33}{8} =\\\frac{11}{8}[/tex]
If we wish, we can convert this into a mixed number:
[tex]\frac{11}{8}= \\1\frac{3}{8}[/tex]
or, 1 hour and 22.5 minutes.
Therefore, Wanda spent [tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes studying math.

Find the PERIMETER and the AREA of the following figure,
16 ft
8 ft
10 ft
9514 1404 393
Answer:
perimeter: 36 +16√5 ft ≈ 71.777 ftarea: 288 ft²Step-by-step explanation:
Perimeter
The perimeter is the total length of all the sides. The length of the horizontal sides is 8 ft + 10 ft = 18 ft. The length of the slant sides can be found using the Pythagorean theorem. For side length s, we have ...
s^2 = 8^2 + 16^2
s^2 = 64 +256 = 320
s = √320 = 8√5
Then the perimeter is ...
P = 2(8√5 + 18) = 36 +16√5 ≈ 71.777 . . . feet
__
Area
The area is given by the formula ...
A = bh
where b is the base and h is the height.
A = (18 ft)(16 ft) = 288 ft²

I've rearranged the tiles in the proper order
===================================================
Explanation
For step 2, we rewrite each expression in terms of sines and/or cosines. For instance, tan = sin/cos.
In step 3, we focus on the stuff in the numerator only. So we focus on sin/cos+cos/sin. In this step, we multiply top and bottom of the first fraction by sine. We multiply top and bottom of the second fraction by cos. These steps are done to get the LCD.
In step 4, we are able to add the fractions because both fractions have the same denominator.
In step 5, we use the pythagorean trig identity sin^2+cos^2 = 1.
In step 6, we use the idea that (A/B) divide by (C/D) = (A/B)*(D/C).
The box plot show the weights in ounces of 15 different bags of almonds. About how many bags contained less than 27 ounces:
Answer:
See explanation
Step-by-step explanation:
The question is incomplete, as the box plot is not given. A general approach to the question, is as follows:
First, identify the 27 mark on the box plot.
Next, count the number of data less than 27.
Take, for instance, there are 6 dots or marks before 27;
This means that 6 bags contain less than 27 ounces
El piso de un habitación es de forma cuadrada. Tiene 10m de longitud por lado y debe ser cubierto con losetas cuadradas de 25cm de lado. ¿Cuantas losetas serán necesarias?
Answer:
4 fichas
Step-by-step explanation:
Paso 1
Encontramos el área de la habitación cuadrada.
Área de un cuadrado = longitud del lado²
Longitud lateral = 10 cm
Área del piso cuadrado = (10cm) ²
= 100 cm²
Paso 2
El suelo debe estar cubierto con baldosas cuadradas de 25 cm.
Por lo tanto: El número de mosaicos que serán necesarios =
Área del piso cuadrado ÷ Área de las baldosas
= 100cm² / 25 cuadrados

Find the 25th term of the sequence -7,-22,-37.
Answer:
a₂₅ = - 367
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 22 - (- 7) = - 37 - (- 22) = - 15
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 15 , then
a₂₅ = - 7 + (24 × - 15) = - 7 - 360 = - 367

There are 6 kittens in the litter, five kittens are black and 1 is brown, what percent of kittens is black?
Answer:
83 1/3 %
Step-by-step explanation:
Take the number of black kittens over the total
5/6
Change to a decimal
.833333
Multiply by 100
83.33333%
.33333 repeating is 1/3
83 1/3 %
Answer:
[tex]83.33\%[/tex]
Step-by-step explanation:
Number of kittens in the litter = 6
Number of Black kittens = 5
Number of Brown Kittens = 1
Now let's find the percentage of black kittens
[tex] = \frac{number \: \: of \: \: black \: \: kittens}{number \: \: of \: \: total \: \: kittens} \times 100\% \\ = \frac{5}{6} \times 100\% \\ \\ = \frac{500}{6} \times 100\% \\ = 83.33\%[/tex]

Linear function:

Linear function:

Step-by-step explanation:
Pattern rule seems subjective and I don't believe there is a technical mathematical term for it, but in terms of linear functions and patterns:
From ages 5 to 8: [tex]y=6x+78[/tex], where [tex]y[/tex] is Fardad's height after age [tex]x[/tex]
Pattern from ages 5 to 8: Fardad grows 6 inches each year (add 6 each year)
From ages 8 to 10, not including 8: [tex]y=11x+38[/tex], where [tex]y[/tex] is Fardad's height after age [tex]x[/tex]
Pattern from ages 8 to 10, not including 8: Fardad grows 11 inches each year (add 11 each year)
