Answer:
50°
Step-by-step explanation:
the angles should add up to 180. there is a 90° angle abd a 40° angle which adds up to 130. 180-130 gives you rour missing angle if 50°.
a metal pile is 500cm long correct to the nearest centimeter the pole is cut into rods each of length 5.8cm correct to the nearest millimeter calculate the largest rod the pole can be cut into
Answer:
86 pieces
Step-by-step explanation:
Given
[tex]Pole = 500cm[/tex]
[tex]Pieces = 5.8cm[/tex]
Required
Determine the largest number of rods
To do this, we simply divide the length of the pole by the length of each piece.
[tex]Number = \frac{Pole}{Pieces}[/tex]
[tex]Number = \frac{500cm}{5.8cm}[/tex]
[tex]Number = \frac{500}{5.8}[/tex]
[tex]Number = 86.2068965517[/tex]
Round down
[tex]Number = 86[/tex]

9514 1404 393
Answer:
143°
Step-by-step explanation:
Angle VUT is the sum of the angles into which it is divided.
∠VUT = ∠VUA +∠AUT
∠VUT = 55° +88°
∠VUT = 143°
A soft-drink manufacturer purchases aluminum cans from an outside vendor. A random sample of 70 cans is selected from a large shipment, and each is tested for strength by applying an increasing load to the side of the can until it punctures. Of the 70 cans, 58 meet the specification for puncture resistance. Find a 95% confidence interval for the proportion of cans in the shipment that meet the specification. Round the answers to three decimal places.
Answer:
The 95% confidence interval for the proportion of cans in the shipment that meet the specification is (0.741, 0.917).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
For this problem, we have that:
70 cans, 58 meet the specification for puncture resistance. This means that [tex]n = 50, \pi = \frac{58}{70} = 0.829[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.829 - 1.96\sqrt{\frac{0.829*0.171}{70}} = 0.741[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.829 + 1.96\sqrt{\frac{0.829*0.171}{70}} = 0.917[/tex]
The 95% confidence interval for the proportion of cans in the shipment that meet the specification is (0.741, 0.917).

HELP PLEASE ASAP MARKING BRAINLY
With the knowledge that m∠1 = 81°, let's use these relationships to find the rest of the angles:
1 and 3 are vertical: their angle measures are the same, so m∠3 = 81°1 and 4 are corresponding: their angle measures are also the same, so m∠4 = 81°Finally, 1 and 2 are supplemental: their angle measures add up to 180°, so 81 + m∠2 = 180, making m∠2 = 99°The manufacturer that Russell works for makes
bicycles. The wholesale price for the bikes is
$200; however, they markup the cost by 55%.
What is the retail price for these bikes?
Answer:
$310
Step-by-step explanation:
200 increase 55% =
200 × (1 + 55%) = 200 × (1 + 0.55) = 310
Given (4,1) and slope=2, write the equation in slope-intercept form
Answer:
y = 2x-7
Step-by-step explanation:
Point-slope equation for line of slope m that passes through (x₀,y₀):
y-y₀ = m(x-x₀)
y-1 = 2(x-4)
Put into slope-intercept form:
y = 2(x-4) + 1
y = 2x - 7
which polynomial represents the difference below? (8x^2+9)-(6x^2+2x+2)
Answer:
The polynomial is 2 x² - 2x + 7
Step-by-step explanation:
Given polynomial
(8 x² + 9 ) - (6x² +2x +2)
= 8 x² +9 - 6x² - 2x -2
= 8x² - 6x² - 2x + 9-2
= 2 x² - 2x + 7
The polynomial is 2 x² - 2x + 7

In triangle ABC, the measure of the exterior angle at point B is 100°. If m∠A is 4 times larger than m∠c, FIND m∠c
pleaseeeeeeeeee!!!!!
Answer:
m<c = 20º
Step-by-step explanation:
We use these following definitions:
The sum of an interior angle with its exterior is of 180º.
The sum of the three interval angles of a triangle is 180º.
The measure of the exterior angle at point B is 100°.
This means that the measure of the interior angle is: 180 - 100 = 80º
m∠A is 4 times larger than m∠c
This means that the measure of angle c is x, and the measure of angle a is 4x. The other angle, B, is 80º. So
[tex]x + 4x + 80 = 180[/tex]
[tex]5x = 100[/tex]
[tex]x = \frac{100}{5}[/tex]
[tex]x = 20[/tex]
The measure of angle C is 20º.

I don't know how to find the slope and y intercept form y=-9x+15
Answer:
Slope=-9, y-intercept=15
Step-by-step explanation:
The slope is always with the x when in slope intercept form, and the y-intercept is the constant (the number with no variable).
Answer:
Slope: 9 y-Intercept Form: 15
Step-by-step explanation:
The formula for slope is y=mx+b. Mx is the slope and b is the y-intercept. Because your equation is written in this form, you can easily find the slope and y-intercept which are 9 and 15. I hope this helps :)

What’s the volume of a cylinder with a base of 25 and height of 6
Lee's family had a garden in the shape of a right triangle. The total area of the garden is 16 square feet. If they expand
the garden to form a triangle with twice the base
and twice the height, by how much will they increase the size of their
garden?
O 16 square feet
• 32 square feet
O
48 square feet
64 square
feet
Answer:
48 square feet
Step-by-step explanation:
Given
Before expansion
[tex]A_1 = \frac{1}{2}bh[/tex] --- area of a triangle
[tex]A_1 = 16ft^2[/tex] --- value of the area
After the base and height were expanded, the area becomes:
[tex]A_2 = \frac{1}{2}BH[/tex]
Where
[tex]B = 2b[/tex]
[tex]H = 2h[/tex]
Substitute 2b for B and 2h for H in [tex]A_2 = \frac{1}{2}BH[/tex]
[tex]A_2 = \frac{1}{2} * 2b * 2h[/tex]
[tex]A_2 = \frac{1}{2} * 2*2*b*h[/tex]
[tex]A_2 = \frac{1}{2} * 4*b*h[/tex]
Rewrite as:
[tex]A_2 = 4 * \frac{1}{2} *b*h[/tex]
[tex]A_2 = 4 * \frac{1}{2}bh[/tex]
Recall that: [tex]A_1 = \frac{1}{2}bh[/tex]
So, we have:
[tex]A_2 = 4 * A_1[/tex]
Substitute 16 for [tex]A_1[/tex]
[tex]A_2 = 4 * 16[/tex]
[tex]A_2 = 64[/tex]
So, the area is [tex]64ft^2[/tex] after the dimensions were expanded
The area increased by:
[tex]Increment = A_2 - A_1[/tex]
[tex]Increment = 64 - 16[/tex]
[tex]Increment = 48[/tex]
It increased by [tex]48ft^2[/tex]
