Answer:
Assuming this: * means a multiplication symbol, the answer is 56.
Step-by-step explanation:
1. Replace every single x with 20.
2. 20 + 20 * 2 - 20/5
3. Simplify the equation
4. 20 + 40 - 4 (Order of operations. To remember this use
P(parentheses)
E(exponents)
M(multiplication)
D(division)
A(addition)
S(subtraction)
Top to bottom represents which operations you should do first while simplifiying an equation. Addition and subtraction are in equal places. This is the same with multiplication and division.
5. 20 + 40= 60 - 4= 56
if 5x-7=13, what is the value of 10x-14
Answer:
10x-14=26
Step-by-step explanation:
x = 4
10 x 4 = 40
40 - 14 = 26
Answer:
26
Step-by-step explanation:
In order to answer this question, we must first find what x equals, so we need to solve for x in the equation 5x - 7 = 13:
5x - 7 = 13
+7 +7
5x = 20
/5 /5
x = 4
Now, we plug in 4 for 'x' in the equation 10x - 14:
10(4) - 14 =
40 - 14 =
26
So, 10(4) - 14 = 26

-5+2a=4a-4-3a help plz and thank you
Answer:
a=1
Step-by-step explanation:
To make this easier, combine like terms first.
-5+2a=4a-4-3a
-5+2a=a-4
Then, add 5 on both sides.
-5+2a=a-4
+5 +5
2a=a+1
Now, subtract a on both sides.
2a=a+1
-a -a
a=1

Answer:
The mapping represents y as a function of x, because each x value corresponds to exactly 1 y value.
Step-by-step explanation:
Functions are defined to map out to only one value so that rules everything else out and leave us with only one answer.

Make a list of professionals who routinely apply geometry in their work. Start by reading about these careers that use geometry
Answer:
Architect
Surveyor
Mechanical Engineer
Drafter
Step-by-step explanation:
Architects utilize geometric principles while designing layouts for their ongoing projects, which can include buildings, electrical systems, and plumbing architecture.
Surveyors use geometry to take exact measurements of boundaries for different types of property.
Mechanical engineers, some of the most diversified engineers, use a multitude of geometric concepts to design mechanical devices, or update existing structures
Drafters use the same geometric knowledge and applications as architects and engineers, drafters create design plans with the use of computer-aided design (CAD) software.
Answer:
architects
civil engineers
designers who use computer-aided design
astronomers
air traffic controllers
interior designers
jewelry designers
painters
photographers
sculptors
landscape designers
carpenters
plumbers

Can someone please help. I'm offering a lot of points because this answer needs an explanation. Statement proof style would be helpful, but it's not totally needed
Answer:
See below
Step-by-step explanation:
Given∠A ≅ ∠B and CD⊥ABTo prove CD bisects ∠ACBSolutionAs CD⊥AB, ∠BDC = ∠ADC = 90°
∠BDC ≅ ∠ADC
∠BCD = 180 - (∠BDC + ∠DBC)and
∠ACD = 180 - (∠ADC + ∠DAC)We can substitute ∠ADC with ∠BDC and ∠DAC with ∠DBC
Then we get same equation for ∠BCD and ∠ACD
Therefore ∠BCD = ∠ACD = 1/2∠ACB
It proves that CD bisects ∠ACB

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of . Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of . The value of the mean is 12 peas. (Type an integer or a decimal. Do not round.) The value of the standard deviation is nothing peas. (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of nothing peas or fewer are significantly low. (Round to one decimal place as needed.) Values of nothing peas or greater are significantly high. (Round to one decimal place as needed.) c. Is a result of peas with green pods a result that is significantly low? Why or why not? The result ▼ is is not significantly low, because peas with green pods is ▼ less than greater than equal to nothing peas. (Round to one decimal place as needed.)
Answer:
hello some parts of your question is missing below is the complete question
Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.25 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 36
.a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 36
The value of the mean is
μ=___ peas.
The value of the standard deviation is
σ=___peas.
b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.
Values of ___ peas or fewer are significantly low.
Values of ___ peas or greater are significantly high.
c. Is a result of 2 peas with green pods a result that is significantly low? Why or why not?
The result (is, is not) significantly low, because 2 peas with green pods is (greater than, equal to, less than) peas.
Answer : A) mean : 9, std = 2.6
B) significantly low value : = 3.8, significantly high value = 14.2
C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods
Step-by-step explanation:
given data :
probability ( p )= 0.25
number of groups ( n )= 36
A ) i) Mean of the of the peas ( u )
u = np = 36 * 0.25 = 9
ii) standard deviation of the peas ( б ) = [tex]\sqrt{np(1-p)} = \sqrt{9(1-0.25)}[/tex] = 2.60
B) Using the range rule of thumb to find the values separating results that are significantly low or significantly high.
note : assuming z = 2 and error = 5%
i) The values that are significantly lower
u - zб = 9 - (2*2.6 )
= 3.8
ii) The values that are significantly higher
u + zб = 9 + (2*2.6)
= 14.2
C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods

Solve for x.
4x +15 > 23
Answer: x > 2
Step-by-step explanation:
First, you need to isolate the variable by subtracting each side by 15.
4x + 15 > 23
-15 -15
= 4x > 8
To get the value for the variable, divide each side by 4.
4x/4 = x 8/2 = 2
x>2
Answer:
Step-by-step explanation:
4x + 15 > 23
4x > 8
x > 2

All side lengths in quadrilateral PQRS measure 6 units. A transformation maps PQRS to P'Q'R'S'. All sides of P'Q'R'S' measure 1 unit. Is the transformation an isometric transformation? Explain
Answer:
no. in an isometric transformation, the side lenths all stay the same. in this transformation (which is a dilation), the size lengths decreased, so it is not isometric.

Answer:
sin = -√3/2cos = -1/2tan = √3sec = -2csc = (-2/3)√3cot = (√3)/3Step-by-step explanation:
See the attached picture for a drawing of the angle and its terminal point coordinates. Those are (cos(4π/3), sin(4π/3)), so we have the following trig function values:
sin(4π/3) = -√3/2
cos(4π/3) = -1/2
tan(4π/3) = sin/cos = √3
sec(4π/3) = 1/cos = -2
csc(4π/3) = 1/sin = -(2√3)/3
cot(4π/3) = 1/tan = (√3)/3

It helps to know that 1/√a = (√a)/a. This lets you write the ratios with a rational denominator in each case.

Answer:i think 39
Step-by-step explanation:
In the coordinate plane, the point X (2, 3) is translated to the point x'(5,-2). Under the same translation, the points Y(-1, 1) and Z(5, 5) are translated
to Y' and Z', respectively. What are the coordinates of Y' and Z'?
Add steps to solve !! Please
Answer:
Y'=(2,-4)
Z'=(8,0)
Step-by-step explanation:
X + T = X'
(2,3) + (T) = (5,-2)
T = (3,-5)
Y' = Y + T = (2,-4)
Z' = Z + T = (8,0)
