What is the value of x?
x = 25
x = 180
x = 135
x = 20
Answer:
x=20
Step-by-step explanation:
Since all the angles in any give triangle adds up to 180, we can make an equation from this geometry question. x+5+7x-5+x=180 (Adding all the angles). If you simplify this, it becomes 9x=180, or x=20.
(-2) elevado a -4 respuesta porfavor
Answer:
16
Step-by-step explanation:
-2 to the 4th power is expressed as;
= (-2)^-4
= -2 × -2 × -2 × -2
= (-2×-2)×(-2×-2)
= 4×4
= 16
Hence -2 to the 4th power is equal to 16
Write two congruence statements for the congruent triangles. i will give out brainly
Answer:
If two sides in one triangle are congruent to two sides of a second triangle, and also if the included angles are congruent, then the triangles are congruent. ... If in triangles ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then triangle ABC is congruent to triangle DEF.
Find the perimeter of a triangle with sides that measure 2.7km,3.3km,4.3km
Answer:
10.3 km
Step-by-step explanation:
Perimeter = side1 + side2 + side3
side1 = 2.7 km
side2 = 3.3 km
side3 = 4.3 km
Perimeter = 2.7 + 3.3 + 4.3
Perimeter = 10.3 km
Plan A $17 plus 0.10 for each min of calls. Plan B &13 plus an additional 0.15 for each min. What amount do the two plans cost the same?
Answer:
80 minutes ; $25
Step-by-step explanation:
Let x = number of minutes
Plan A :
17 + 0.1x - - - (1)
PLAN B :
13 + 0.15x - - - (2)
Both plans will cost the same when ;
17 + 0.1x = 13 + 0.15x
Solve for X
0.1x - 0.15x = 13 - 17
-0.05x = - 4
divide both sides by - 0.05
-0.05x / - 0.05 = - 4 / - 0.05
x = 80 minutes
Amount :
17 + 0.1(80) = 17 + 8 = $25
A veteran math teacher at a large high school claims that 93% of their students pass the state’s final exam. A random sample of 120 of the teacher’s students was chosen, and 108 passed the state’s final exam. Let p hat = the proportion of the random sample who passed the state’s final exam.
The probability that 90% or fewer of this teacher’s students passed the state’s final exam is 0.096. Does this result provide convincing evidence against the teacher’s claim?
Yes, it is expected that at least 90 of the students will pass the state’s final exam.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
Answer:
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.

A Camera has a list price $560.99 before tax if the sales tax rate is 7.75% find the total cost of the camera wit sale tax included round your answer to the cent
Answer:
$604.47
Step-by-step explanation:
Given data
Cost of camera= $560.99
Tax= 7.75%
Let us find the amount of the tax
=7.75/100* 560.99
=0.0775*560.99
=$43.48
Hence the amount of the tax is $43.48
Therefore the total cost is
=43.48+560.99
=$604.47

The shape of a patio is triangle without hight of 8 ft and base of 17 ft what is the cost of out door carpeting to cover the patio of the carpeting costs 6.50 per ft
Answer:
$442
Step-by-step explanation:
Given :
Height of patio, h = 8ft
Base of patio = 17 ft
Cost of carpeting = $6.50 per ft²
Area of triangular patio :
Area = 1/2 * base * height
Area = 0.5 * 17 * 8
Area of patio = 4 * 17
Area of patio = 68 ft²
Cost of carpeting :
Area of patio * contains st per ft²
68 * 6.50
= $442

Bonnie's doctor recommended that she drink 2cups of milk per day. If she buys 3 quarts of milk,will it be enough milk to last 1 week?
Answer:
She does not have enough milk to last for 1 week
Step-by-step explanation:
From the question, we are told that:
Bonnie's doctor recommended that she drink 2cups of milk per day.
Step 1
The number of days in a week is 7 days
Hence
1 day = 2 cups of milk
7 days = x
Cross Multiply
x = 7 × 2 cups of milk
= 14 cups of milk.
Step 2
If she buys 3 quarts of milk,will it be enough milk to last 1 week?
We have the conversion rate as:
1 quart = 4 cups
Therefore,
1 quart = 4 cups
3 quarts = x cups
Cross Multiply
x cups = 3 quarts × 4 cups/1 quart
x cups = 12 cups of milk
This means she bought 12 cups of milk.
Therefore, from the above calculation, she does not have enough milk to last for 1 week because due to her doctor's recommendation, she need 14 cups of milk for the week but she only bought 12 cups of milk

simplify and leave answer in decimal form (3,6×10 to the power 6)-(5,2×10 to the power 5 show steps of calculations
Answer:
3.08×10 to the power of 4
Step-by-step explanation:
3.6×10the power of 6 =3,600,000
and 5.2× 10 to the power of 5 = 520,000
then the next step is to substract
3,600,000-520,000=308,000
then when we change it to decimal place we will get=3.08×10 to the power of 5
