Answer:
20 degrees
Step-by-step explanation:
The sum of inner angles of a triangle is 180 degrees
120 + 40 + x = 180
160 + x = 180
x = 20
Answer:
A + 120 + 40 = 180 (interior angles of a triangle equal to 180°)
A = 180-120-40
A = 20°
The length of a field in feet is a function f(n) of the length nin yards. Write a function rule for this situation.
Given:
The length of field is n yards.
The length of a field in feet is a function f(n).
To find:
The function rule for this situation.
Solution:
We know that,
1 yard = 3 feet
Using this conversion, we get
n yard = 3n feet
The length of field is n yards. So, the length of the field is 3n feets.
The length of a field in feet is a function f(n). So,
[tex]f(n)=3n[/tex]
Therefore, the required function rule for this situation is [tex]f(n)=3n[/tex].

answer:
N(t)=2×[tex]1.7^{t}[/tex]
17
15
step by step explain:
before lesson (t=0), she knows 2 words.
after a week (t=1), she knows
2×(1+70%)=3.4 words
after one more week (t=2), she knows
3.4×(1+70%)=5.78 words
one more week later (t=3), she knows
5.78×(1+70%)=9.826 words
and so on ...
from pattern shown above, we know that she knows
2×[tex]1.7^{t}[/tex] words after t weeks
so N(t)=2×[tex]1.7^{t}[/tex]
after 4 weeks (t=4), she knows 2×[tex]1.7^{4}[/tex]=16.7042≈17 words
for learning 5000 words, she need:
2×[tex]1.7^{t}[/tex]=5000
[tex]1.7^{t}[/tex]=2500
t log(1.7)=log(2500)
t=[tex]\frac{log(2500)}{log(1.7)}[/tex]
=14.7448727
≈15 (round up)
Answer:
(a) N(t) = 2(1.7)^t
(b) 17
(c) 15
Step-by-step explanation:
(a) N(t) = 2(1.7)^t
There is a 2 because she starts with 2 words. The 1.7 is since her vocabulary grows by 70%. Finally, t represents the weeks. (it is an exponent)
(b) Just plug in the equation
N(4) = 2(1.7)^4
N(4) = 2(8.3521)
N(4) = 16.7042
Round, so it is 17
(c) Once again, plug in the equation
5000 = 2(1.7)^t
2500 = (1.7)^t
use a calculator for the part below
log1.7(2500) = log1.7(1.7)*t
t = log1.7(2500)
t = 14.7448
Round, so it is 15
If point P is Nine-elevenths of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into?
9:2
9:9
9:11
9:13
Given:
Point P is Nine-elevenths of the distance from M to N.
To find:
The ratio in which point P partition the directed line segment from M to N.
Solution:
It is given that, point P is Nine-elevenths of the distance from M to N. So,
[tex]\dfrac{MP}{MN}=\dfrac{9}{11}[/tex]
It can be written as
[tex]\dfrac{MP}{MN}=\dfrac{9}{11}[/tex]
Let the lengths of MP and MN are 9x and 11x respectively. Then,
[tex]PN=MN-MP[/tex]
[tex]PN=11x-9x[/tex]
[tex]PN=2x[/tex]
Now,
[tex]\dfrac{MP}{PN}=\dfrac{9x}{2x}[/tex]
[tex]\dfrac{MP}{PN}=\dfrac{9}{2}[/tex]
[tex]\dfrac{MP}{PN}=9:2[/tex]
It means, point P divides the line segment MN in 9:2.
Therefore, the correct option is A.

what is the slope of a line containing points (2,-1) (3,5)
Answer:
slope(m)=6
Step-by-step explanation:
(2 , -1)=(x1 , y1)
(3 , 5)=(x2 , y2)
use formula : y2 - y1/x2 - x1
=5-(-1)/3-2
=5+1/1
=6/1
=6
therefore slope of a line is 6.

The angle of elevation to a nearby tree from a point on the ground is measured to be
31°. How tall is the tree if the point on the ground is 62 feet from the tree? Round
your answer to the nearest tenth of a foot if necessary.
Answer:
37.3 ft
Step-by-step explanation:
tan A = opp/adj
tan 31° = x/62
x = 62 * tan 31°
x = 37.3 ft
The height of the tree is 37.25 ft if the point on the ground is 62 feet from the tree.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
Trigonometric ratios are used to demonstrate the connection between the sides and angles of a right-angled triangle.
Let h denote the tree if the point on the ground is 62 feet from the tree.
The angle of elevation = 31°. Hence:
tan 31° = h/62
h = 62 × tan 31°
h = 37.25 ft
Thus, the height of the tree is 37.25 ft if the point on the ground is 62 feet from the tree.

Answer:
Measure of angle K is 52.5 degrees
Step-by-step explanation:
Here, we have a case of two sides being congruent
mathematically when two sides are congruent, then we have an isosceles triangle
For an isosceles triangle, the base angles are equal
LM faces K , while M faces KL
What this mean is that L faces KM
From above, we can see that K = M = ?
Let us call this x
Mathematically, the sum of angles in a triangle is 180 degrees
75 + x + x = 180
2x = 180-75
2x = 105
x = 105/2
x = 52.5

A linear binomial with a leading coefficient of 2
Given:
A quadratic monomial with a leading coefficient of 6.
A linear binomial with a leading coefficient of 2.
To find:
The mathematical terms for the given statements.
Solution:
Monomial: The expression with single term.
Binomial: The expression with two terms.
Quadratic: Highest power of the variable is 2.
Linear: Highest power of the variable is 1.
Coefficient: In the product of a number and a variable, the number is known as the coefficient of that variable.
The first statement is "A quadratic monomial with a leading coefficient of 6".
Quadratic monomial means single term with degree 2. The leading coefficient of 6. So, the term is [tex]6x^2[/tex].
The second statement is "A linear binomial with a leading coefficient of 2".
Linear binomial means [tex]ax+b[/tex], where a and b are real values. The leading coefficient is 2. So, [tex]a=2[/tex].

A sculptor needs to lift a piece of marble it’s a cuboid with dimensions 1 by 0.2 by 0.5 marble has a density of 2.7 what’s the mass in kg
Answer:
Mass of piece of marble = 0.27 kilogram
Step-by-step explanation:
Given:
Dimensions of cuboid = 1 x 0.2 x 0.5
Density of marble = 2.7
Find:
Mass of piece of marble
Computation:
Volume of cuboid = (l)(b)(h)
Volume of marble = 1 x 0.2 x 0.5
Volume of marble = 0.1
Mass = Density x Volume
Mass of piece of marble = Density of marble x Volume of marble
Mass of piece of marble = 2.7 x 0.1

A rental car company charges $80 per day to rent a car and $0.10 for every mile driven. Alyssa wants to rent a car, knowing that: She plans to drive 150 miles. She has at most $300 to spend. Which inequality can be used to determine xx, the maximum number of days Alyssa can afford to rent for while staying within her budget?Geq30080x+15≥300 15x+80\leq30015x+80≤300 80x+15\leq30080x+15≤300 15x+80\geq30015x+80≥300
Multiply the number of days (x) by the amount per day (80) to get 80x.
She is driving 150 miles at 0.10 per mile so multiply to get the mileage cost: 150 x 0.10 = 15
Add this to the daily amount:
80x+15
She can spend up to 300, so less than or equal to 300:

Darrel receives a weekly salary of $435. In addition, $12 is paid for every item sold in excess of 100 items. How much will Darrel earn for the week if he sold 189 items?
Answer:

explanation:
12×189=2268
2268+435=2703
Darrel earned 1503 dollars that week.
How to count no. of digits from a certain no. to a certain no. ?Suppose we are given how many no. are there from 224 to 358.
To find do the following (358 - 224 + 1) = 135 numbers.
According to the question Darrel receives a weekly salary of 435 dollars. In addition, 12 dollars is paid for every item sold in excess of 100 items.
Here excess of 100 items means after 100 which is 101.
He sold 189 items so his addition earning is for (189 - 101 + 1) = 89 items.
Given for each item he is paid 12 dollars.
∴ For 89 items he is paid (89 × 12) dollars which is
= 1068 dollars.
So in that week Darrel earns total of (435 + 1068) dollars.
= 1503 dollars.
