Answer: B = 44
Step-by-step explanation:
The measure of ∠B = 44°.
We have two angles ∠A and ∠B which are complementary of each other.
We have to find the measure of ∠B.
What are Complementary angles?Two angles are said to be complementary if their sum is equal to 90°.
Mathematically - x + y = 90°
According to the question -
∠A = (6x+22)°
∠B = (7x+16)°
Now, ∠A and ∠B are Complementary angles. Therefore -
∠A + ∠B = 90°
(6x + 22) + (7x + 16) = 90
13x + 38 = 90
13x = 52
x = 4
Therefore -
∠B = 7x + 16 = 7 x 4 + 16 = 44°.
Hence, the measure of ∠B = 44°.

Write both number with the same power of 10, factor out that power of 10 (since it's common to both terms), then simplify to standard scientific notation (that is, a.bcd... × 10⁻ⁿ):
(8.28 × 10⁻⁵) - (4.1 × 10⁻⁷) = (828 × 10⁻⁷) - (4.1 × 10⁻⁷)
… = (828 - 4.1) × 10⁻⁷
… = 823.9 × 10⁻⁷
… = 8.239 × 10⁻⁵

After 2014 the sales of new cell phones without cameras began declining. The number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240, where x is the number of years after 2014
Answer:
60,000 people
Step-by-step explanation:
Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,
x is the number of years after 2014
We can find the number of people that bought the cell phone in 2020. In year 2020, that will be after 6years
Substitute x = 6 into the expression
y=-30x+240
y=-30(6)+240,=
y = -180 + 240
y = 60
Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

Answer:
a = 2, b = 3
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , so
3a + 11 = a + 15 ( subtract a from both sides )
2a + 11 = 15 ( subtract 11 from both sides )
2a = 4 ( divide both sides by 2 )
a = 2
and
3b + 5 = b + 11 ( subtract b from both sides )
2b + 5 = 11 ( subtract 5 from both sides )
2b = 6 ( divide both sides by 2 )
b = 3

Determina el perimetro de las figuras geometricas que forman la rayuela
Perimetro: L=50 cm
Expresión:
Sustitucion:
P=_______/
La figura es un cuadrado y cada lado mide 50 cm
Answer:
2000cm
Step-by-step explanation:
Rayuela es un juego jugado por niños que se compone de 10 cuadrados.
Se nos da a partir de la pregunta anterior, la longitud del lado de un cuadrado = 50 cm
La fórmula para el perímetro de un cuadrado es 4a
Donde a = longitud del lado
El perímetro de 1 cuadrado =
4 × 50 cm
= 200cm
El perímetro de los cuadrados totales en la rayuela.
1 cuadrado = 200 cm
10 cuadrados = x
Multiplicar cruzada
x = 10 × 200 cm
x = 2000 cm
Por lo tanto, el perímetro de las figuras geométricas de una rayuela = 2000cm.
Simplify completely.
(2 + 3i) + (-4+i)
Answer:
-2+4i
Step-by-step explanation:
Simplify by combining the real and imaginary parts of each expression.
The simplified form of the complex expression is -2 + 4i.
What are Complex Numbers?Complex numbers are numbers which are of the form [tex]a+ib[/tex],
where a and b are real numbers and i is the imaginary number called iota whose value is [tex]i^{2}[/tex] = -1.
Given expression is (2 + 3i) + (-4 + i).
Addition of complex numbers is defined as,
(a + ib) + (a' + ib') = (a + a') + i(b + b')
Using the definition of addition of complex numbers, given expression can be added as,
(2 + 3i) + (-4 + i) = (2 + -4) + i(3 + 1) = -2 + 4i
Hence the resulting value is -2 + 4i.

The measure of ABD is (0.18x + 67) degrees and the measure of CBD is (0.07 + 48) degrees. Find the value of X
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]ABD = 0.18x +67[/tex]
[tex]CBD = 0.07x + 48[/tex]
Required
Find x
The question is incomplete as the relationship between ABD and CBD is not stated.
Assume ABD = CBD
The solution is:
[tex]0.18x + 67 = 0.07x + 48[/tex]
Collect like terms
[tex]0.18x - 0.07x= - 67 + 48[/tex]
[tex]0.11x= -19[/tex]
Solve for x
[tex]x = -\frac{19}{0.11}[/tex]
[tex]x = -172.72[/tex]
Assume ABD and CBD are supplementary
The solution is:
[tex]ABD + CBD=180[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 180[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 180[/tex]
[tex]0.25x = 65[/tex]
Solve for x
[tex]x = \frac{65}{0.25}[/tex]
[tex]x = 260[/tex]
Assume ABD and CBD are complementary
The solution is:
[tex]ABD + CBD=90[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 90[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 90[/tex]
[tex]0.25x = -25[/tex]
Solve for x
[tex]x = \frac{-25}{0.25}[/tex]
[tex]x = -100[/tex]

Section the figure into two 3D shapes.
We get both figures to be a rectangular prism.
The Volume of a rectangular prism is length times width times height.
V (of top Rectangular Prism) = 2 × 2 × 4 = 16
V (of bottom Rectangular Prism) = 6 × 4 × 2 = 48
Now, we add those two volumes together to get the volume of the irregular figure.
16 + 48 = 64.
The volume of the irregular figure is 64 [tex]cm^3[/tex]

There are 48 students in a class and 6 of them are girls. What percent are boys
Answer:
87.5%
Step-by-step explanation:
If there are 48 students in total and 6 girls, then the remaining students are boys
The number of boys = 48 - 6 = 42
Now, calculate the %
42/48 x 100 = 7/8 x 100 = 87.5%
Hope this helps
If there are 48 students in a class and 6 of them are girls then the percentage of boys in the class is 87.5%,
Use the concept of percentage defined as:
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Given that,
Number of students = 48
Number of girls = 6
Then number of boys = 48 - 6
The number of boys = 42
Therefore,
The percentage of boys in the class is,
[tex]\dfrac{42}{48}\times 100= 87.5 \text{ percent}[/tex]
Hence,
There are 87.5 percent of boys in the class.
