Answer:
She bought 24 Tangram puzzles
Step-by-step explanation:
Let the number of Tangram puzzles be t and the number of IQ puzzles be i
The sum of all the puzzles is 40;
i + t = 40 ••••••(i)
Cost of all Tangram puzzles at a cost of $4 per one will be;
4 * t = $4t
cost of all Iq puzzles at a cost of $2 per one is
2 * i = $2i
Sum
paid for all is $128
so;
4t + 2i = 128 •••••••(ii)
From equation i;
i = 40-t
Substitute into ii
4t + 2(40-t) = 128
4t + 80 - 2t = 128
2t = 128-80
2t = 48
t = 48/2
t = 24
A bag contains 42 red, 45 green, 20
yellow, and 32 purple candies. You
pick one candy at random. Find the
probability that it is green or yellow.
Answer:
65/139 fraction form
0.47 decimal form
Answer:
Step-by-step explanation:
Total sample space , n (s) = 139
no of green candies , n (g) = 45
no. of yellow candies , n (y) = 20
Probability that is green or yellow is
P( g or y) = P(g) + P(y)
= n(g) / n(s) + n (y) / n(s)
= 45 / 139 + 20 / 139
= 65 / 139
hope it will help :)
What is the equation of the line that passes through the point (-6,4)
and has a slope of -5/6
Answer: y = -5/6 x - 1
Step-by-step explanation:
The slope is -5/6, which is why x = -5/6. The - 1 is so the line on the graph will pass through (0,-1) and (-6,4).
What is the equation of the line that passes through the point (-4,-3)and has a slope of 3/4
Answer:
y=3/4x
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=3/4(x-(-4))
y+3=3/4(x+4)
y=3/4x+12/4-3
y=3/4x+3-3
y=3/4x

Which polynomial is written in standard form ?
9514 1404 393
Answer:
H
Step-by-step explanation:
Standard form has the highest-degree term first. That is the case only for the polynomial of H.
(The degree of a term is the sum of the exponents of its variables.)

What is the total length of all the ski trails that are 2 7/8 miles long?
Answer:
[tex]Total\ length = 8\frac{5}{8}\ miles[/tex]
Step-by-step explanation:
Given
See attachment for ski trails
Required
Total length of [tex]2\frac{7}{8}[/tex] ski trails
From the attached figure, there are 3 skis with length [tex]2\frac{7}{8}\ miles[/tex]
So:
The total length is:
[tex]Total\ length = 3 * 2\frac{7}{8}[/tex]
Express fraction as improper fraction
[tex]Total\ length = 3 * \frac{23}{8}[/tex]
[tex]Total\ length = \frac{3 *23}{8}[/tex]
[tex]Total\ length = \frac{69}{8}[/tex]
[tex]Total\ length = 8\frac{5}{8}\ miles[/tex]

finding angle measures with trig. Find the missing angle measures. Round to the nearest whole number
Answer:
let angle be x
Step-by-step explanation:
relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=13/26
x=sin-¹(13/26)=30°
2.relationship between perpendicular and base is given by tan angle
tan x =p/b
tan x =7/16
x=tan -¹(7/16)=23.63°
3.relationship between between perpendicular and base is given by tan angle
tan x =p/b
tanx=31/50
x=tan-¹(31/50)=31.8°
4.relationship between base and hypotenuse is given by cos angle
cos x =b/h
cos x=5/7
x=cos-1(5/7)=44.4°
5.relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=4/14
x=sin-¹(4/14)=16.6

The radius of a circle is 4 centimeters. What is the angle measure of an arc bounding a sector with area 2 square centimeters?
Answer:
Measure of the arc = 14.32°
Step-by-step explanation:
Radius of a circle = 4 cm²
Area of the circle = πr²
Here, r = radius of the circle
Area of the circle = π(4)²
= 16π cm²
= 50.265 cm²
Since, area of a sector = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]
Here, θ = Central angle subtended by the arc Or measure of arc
Area of the sector given as 2 cm²
2 = [tex]\frac{\theta}{360}(50.265)[/tex]
θ = 14.32°
Therefore, measure of the arc = 14.32°.
