Quadrilateral ABCD is inscribed in this circle. What is the measure of angle a?
Answers
Answer:
Step-by-step explanation:
The rule is that opposite angles are supplementary. Therefore, angle A plus angle C = 180:
angle A + 43 = 180 and
angle A = 180 - 43 so
angle A = 137

QUESTION 2 Write the slope-intercept form of the equation of the line through the gran point micia the grea slope through: (5,-2), siope--1 Oay=-2=6 Oby=-2-3 O cy=-x=3 Ody=-z-6
Answers
Answer:
y = -x+3
Step-by-step explanation:
Slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -1x +b
Using the point for x and y we can calculate b
-2 = -1(5)+b
-2 = -5+b
Add 5 to each side
-2+5 = b
3 = b
y = -x+3
There are j cars at the Rockford dealership and k cars at the Robinson dealership. The Robinson dealership has 6 more than three times as many cars as the Crockford dealership. What is the value of k in terms of j?
Answers
Answer:
[tex]k=3j+6[/tex]
Step-by-step explanation:
We can setup an equation in terms of k and j:
[tex]k=3j+6[/tex]
We get this equation because there are 6 more than 3 times the Crockford cars in the Robinson dealership. We see that the equation already is the value of k in terms of k, so we have our answer.
Sam feels that students score better on math tests that take place on Fridays. The school provides Sam with the school math test average, but they cannot separate them by date taken. The school is too large for him to ask every student, so he randomly selects a sample of willing students' test scores after the next Friday's math test. He uses the method of hypothesis testing to compare the Friday scores against the true average of all scores. Frame the correct set of hypotheses for his research. Decide where the rejection region will lie.
Answers
Answer:
H0 : μ ≤ x
H1 : μ > x
The hypothesis :
The null hypothesis, H0 : μ ≤ x
The alternative hypothesis, uses the Friday score samples to compare the hypothesis ;
The alternative hypothesis, H1 : μ > 8
For then null, the mean scores is assumed to be the same, and has such mean of Friday's test score takes the value of the population.
Let the population mean value = x
The alternative hypothesis is the claim that the sampled mean gives a greater value than the population mean :
H1 : μ > x
there are unspecified number of cows and hens in a den. if there are total of 30 heads and 80 legs in a den, find the number of cows and hens in a den.
Answers
Let x be the number of cow.
Number of hens=180-x.
Since cows have 4 legs and hens 2,
So, 4x+2(180-x)=420.
or, 4x+360–2x=420
or, 2x=420–360
or, 2x=60
or,x=30.
So, number of cows is 30.

The formula p=nc-e gives the profit p when a number of items n are each sold at a cost c and expenses e are subtracted. If p = 3750, n = 3000, and e = 900, what is the value of c?
Answers
Answer:
1.55
Step-by-step explanation:
p =nc-e
p=3750, n=3000, e=900, c=?
3750 = 3000c - 900
3750 + 900 = 3000c
4650 = 3000c
3000c = 4650
c = 4650/3000
c = 1.55

What is the 100th term of the arithmetic sequence below?
4, 11, 18, 25
Answers
Answer:
a₁₀₀ = 697
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = a₂ - a₁ = 11 - 4 = 7 , then
a₁₀₀ = 4 + (99 × 7) = 4 + 693 = 697
Una empresa que trabaja en un mercado de competencia perfecta tiene una función de costos totales CT=Q^3-45Q^2+600Q+1.200 Las funciones de oferta y demanda de este mercado son: Qo=5P-300 y Qd=2.860-8P. Recuerde que la condición para maximizar beneficios dice que la empresa habrá de producir una cantidad tal que haga igualar sus costos marginales con el precio de equilibrio de mercado.
Answers
Answer:
La cantidad producida para maximizar las ganancias es de 915 unidades
Step-by-step explanation:
Pregunta: Calcule cuánto producirá para maximizar las ganancias.
La función de costo dada se presenta de la siguiente manera;
CT = Q³ - 45 · Q² + 600 · Q + 1200
La función de suministro es Qo = 5 · P - 300
La función de demanda es Qd = 2860 - 8 · P
A precio de equilibrio, tenemos;
Qo = Qd
Por lo tanto;
5 · P - 300 = 2860 - 8 · P
13 · P = 2.860 + 300 = 3.160
P = 3160/13
Por lo tanto;
Q = 2860 - 8 × (3160/13) = 11900/13 ≈ 915,38
La cantidad producida que maximiza las ganancias es de aproximadamente 915 unidades.
El costo total CT = 915³ - 45 × 915² + 600 × 915 + 1200 = 728,935,950
if 2/5 of the sweets in a bag is 60, how
many sweets would represent 1/3
Answers
Answer:
50 Candy
Step-by-step explanation:
We know that 2/5 of the bag is 60 candy. By taking this information we can conclude that 1/5 of the bag is 30 candy. We know that 1/5 of the bag is 30, so 30 times 5 is 150 candy.
Now that we have found out that there is 150 candy total we can know divde 150 by 3 to find out how much candy is in 1/3 of the bag.
150/3 = 50 Candy
1/3 of the bag represent 50 candy.

Step-by-step explanation:
To solve for b, we want to use the Pythagorean Theorem as given.
b and 7 are the legs, and 12 is the hypotenuse.
[tex]7^2+b^2=12^2[/tex] [exponent]
[tex]49+b^2=144[/tex] [subtract both sides by 49]

Now we know [tex]b=\sqrt{95}[/tex].
How is adding and subtracting radical expressions similar to adding and subtracting variables ?????
Answers
Answer: To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical. If the indices or radicands are not the same, then you can not add or subtract the radicals.
Answer:
combining like terms. if the radicand is the you can combine the radical. this is the same as combining variables as long as the variable is the same if that makes sense
Step-by-step explanation:
so like you can add 7a and 3a because they have the same variable a. you can combined 2 root 2 and 4 root 2 because the radicand is same <3

If the sum of seven odd consecutive numbers is 231, find the middle number.
Answers
Answer:
33
Step-by-step explanation:
(1+x) + (3+x) + (5+x) + (7+x) + (9+x) + (11+x) + (13+x) = 231
7x + 49 = 231
7x = 231 - 49
7x = 182
x = 182/7
x = 26
To find the middle number;
7 + x
= 7+26
= 33
